Public health management of invasive meningococcal disease outbreaks: worldwide 1973-2018, a systematic review.

BACKGROUND: Infectious disease outbreaks are an ongoing public health concern, requiring extensive resources to prevent and manage. Invasive Meningococcal Disease (IMD) is a severe outcome of infection with Neisseria meningitidis bacteria, which can be carried and transmitted asymptomatically. IMD is not completely vaccine-preventable, presenting an ongoing risk of outbreak development. This review provides a retrospective assessment of public health management of IMD outbreaks. METHODS: A systematic search was performed in PubMed and EMBASE. English-language studies reporting on IMD outbreaks and associated public health response were considered eligible. Reporting on key characteristics including outbreak size, duration, location, and public health response were assessed against Strengthening the Reporting of Observational studies in Epidemiology guidelines. A summary of lessons learned and author recommendations for each article were also discussed. RESULTS: 39 eligible studies were identified, describing 35 outbreaks in seven regions. Responses to outbreaks were mostly reactive, involving whole communities over prioritising those at highest risk of transmission. Recent responses identified a need for more proactive and targeted controls. Reporting was inconsistent, with key characteristics such as outbreak size, duration, or response absent or incompletely described. CONCLUSION: There is a need for clear, comprehensive reporting on IMD outbreaks and their public health response to inform policy and practice for subsequent outbreaks of IMD and other infectious diseases.

Impacto de la recolección de residuos domésticos de gran tamaño sobre potenciales criaderos de mosquitos transmisores del dengue en Asunción, Paraguay

Introducción: Los brotes recurrentes de dengue subrayan la necesidad de abordajes más efectivos en la prevención y control de vectores. A menudo, las intervenciones se centran en un enfoque biomédico y de promoción de la salud desde un enfoque individual, sin integrar factores socioambientales ni ser evaluados científicamente Objetivo: Evaluar el impacto de la recolección de residuos domésticos de gran tamaño sobre potenciales criaderos de mosquitos transmisores del dengue en Asunción, Paraguay durante los años 2017 a 2021. Material y métodos: Estudio cuasiexperimental, longitudinal, donde se encuestaron 350 hogares, como línea de base durante el 2017 y una línea de cierre en 108 hogares en 2021. Se utilizó el método de Diferencia en Diferencia (DID) para comparar la presencia de criaderos antes y después de la intervención en 43 hogares intervenidos y 65 no intervenidos. Resultados: La recolección diferenciada fue utilizada principalmente por aquellos hogares que tenían una gran cantidad de residuos sólidos de gran tamaño, pero no para deshacerse de todos estos objetos, sino sólo de una parte (DID de -52% en el número total de criaderos y DID de 1% en número de hogares con criaderos). Encontramos una reducción significativa en el número de total de criaderos de gran tamaño, pero no observamos diferencias en el número total de hogares con criaderos. Factores subjetivos, como la creencia de que los objetos en desuso podrían llegar a ser útiles en el futuro explicaban en gran medida su presencia en los hogares, incluso con el servicio disponible. Conclusiones: El enfoque de la gestión municipal en los residuos voluminosos puede contribuir a la prevención del dengue por el hecho de que no constituyen residuos de generación rápida en los hogares, y su eliminación puede tener un impacto relativamente duradero. El factor subjetivo relacionado con la presencia de estos criaderos en los hogares debe ser objeto de mayores estudios.

Introduction: Recurrent dengue outbreaks underscore the need for more effective approaches to vector prevention and control. Often, interventions focus on a biomedical and health promotion approach from an individual approach, without integrating socio-environmental factors or being scientifically evaluated. Objetive: To evaluate the impact of large household waste collection on potential breeding sites of dengue-transmitting mosquitoes in Asuncion, Paraguay during the years 2017 to 2021. Material and methods: Quasi-experimental, longitudinal study, where 350 households were surveyed, as a baseline during 2017 and a closing line in 108 households in 2021. The Difference-in-Difference (DID) method was used to compare the presence of breeding sites before and after the intervention in 43 intervened and 65 non-intervened households. Results: Differentiated collection was mainly used by those households that had a large amount of large solid waste, but not to dispose of all these objects, but only part of them (DID of -52% in the total number of breeding sites and DID of 1% in the number of households with breeding sites). We found a significant reduction in the total number of large breeding sites but did not observe differences in the total number of households with breeding sites. Subjective factors, such as the belief that disused objects could become useful in the future, were largely responsible for the reduction in the number of large breeding sites. Conclusions: The municipal management approach to bulky waste can contribute to dengue prevention because it does not constitute rapidly generated waste in households, and its disposal can have a relatively long-lasting impact. The subjective factors related to the presence of these breeding sites in households warrant further study.

A Novel Web-Based Application for Influenza and COVID-19 Outbreak Detection and Response in Residential Aged Care Facilities.

Unlabelled: The use of innovative digital health technologies in public health is expanding quickly, including the use of these tools in outbreak response. The translation of a digital health innovation into effective public health practice is a complex process requiring diverse enablers across the people, process, and technology domains. This paper describes a novel web-based application that was designed and implemented by a district-level public health authority to assist residential aged care facilities in influenza and COVID-19 outbreak detection and response. It discusses some of the challenges, enablers, and key lessons learned in designing and implementing such a novel application from the perspectives of the public health practitioners (the authors) that undertook this project.

How to protect long-term care facilities from pandemic-like events? - A systematic review on the effectiveness of non-pharmacological measures to prevent viral respiratory infections.

BACKGROUND: The SARS-CoV-2 pandemic underscored the need for pandemic preparedness, with respiratory-transmitted viruses considered as a substantial risk. In pandemics, long-term care facilities (LTCFs) are a high-risk setting with severe outbreaks and burden of disease. Non-pharmacological interventions (NPIs) constitute the primary defence mechanism when pharmacological interventions are not available. However, evidence on the effectiveness of NPIs implemented in LTCFs remains unclear. METHODS: We conducted a systematic review assessing the effectiveness of NPIs implemented in LTCFs to protect residents and staff from viral respiratory pathogens with pandemic potential. We searched Medline, Embase, CINAHL, and two COVID-19 registries in 09/2022. Screening and data extraction was conducted independently by two experienced researchers. We included randomized controlled trials and non-randomized observational studies of intervention effects. Quality appraisal was conducted using ROBINS-I and RoB2. Primary outcomes encompassed number of outbreaks, infections, hospitalizations, and deaths. We synthesized findings narratively, focusing on the direction of effect. Certainty of evidence (CoE) was assessed using GRADE. RESULTS: We analysed 13 observational studies and three (cluster) randomized controlled trials. All studies were conducted in high-income countries, all but three focused on SARS-CoV-2 with the rest focusing on influenza or upper-respiratory tract infections. The evidence indicates that a combination of different measures and hand hygiene interventions can be effective in protecting residents and staff from infection-related outcomes (moderate CoE). Self-confinement of staff with residents, compartmentalization of staff in the LTCF, and the routine testing of residents and/or staff in LTCFs, among others, may be effective (low CoE). Other measures, such as restricting shared spaces, serving meals in room, cohorting infected and non-infected residents may be effective (very low CoE). An evidence gap map highlights the lack of evidence on important interventions, encompassing visiting restrictions, pre-entry testing, and air filtration systems. CONCLUSIONS: Although CoE of interventions was low or very low for most outcomes, the implementation of NPIs identified as potentially effective in this review often constitutes the sole viable option, particularly prior to the availability of vaccinations. Our evidence-gap map underscores the imperative for further research on several interventions. These gaps need to be addressed to prepare LTCFs for future pandemics.

Surveillance system integration: reporting the results of a global multicountry survey.

OBJECTIVES: Currently, there is no comprehensive picture of the global surveillance landscape. This survey examines the current state of surveillance systems, levels of integration, barriers and opportunities for the integration of surveillance systems at the country level, and the role of national public health institutes (NPHIs). STUDY DESIGN: This was a cross-sectional survey of NPHIs. METHODS: A web-based survey questionnaire was disseminated to 110 NPHIs in 95 countries between July and August 2022. Data were descriptively analysed, stratified by World Health Organization region, World Bank Income Group, and self-reported Integrated Disease Surveillance (IDS) maturity status. RESULTS: Sixty-five NPHIs responded. Systems exist to monitor notifiable diseases and vaccination coverage, but less so for private, pharmaceutical, and food safety sectors. While Ministries of Health usually lead surveillance, in many countries, NPHIs are also involved. Most countries report having partially developed IDS. Surveillance data are frequently inaccessible to the lead public health agency and seldomly integrated into a national public health surveillance system. Common challenges to establishing IDS include information technology system issues, financial constraints, data sharing and ownership limitations, workforce capacity gaps, and data availability. CONCLUSIONS: Public health surveillance systems across the globe, although built on similar principles, are at different levels of maturity but face similar developmental challenges. Leadership, ownership and governance, supporting legal mandates and regulations, as well as adherence to mandates, and enforcement of regulations are critical components of effective surveillance. In many countries, NPHIs play a significant role in integrated disease surveillance.

Incidence and disease burden of autoimmune inflammatory rheumatic diseases after non-pharmaceutical interventions in the COVID-19 era: A nationwide observational study in Korea.

BACKGROUND: Infections are considered risk factors for autoimmune inflammatory rheumatic diseases (AIRDs), the incidence of which is considered to have been impacted by the COVID-19 pandemic. The impact of non-pharmaceutical interventions (NPIs) on the incidence of AIRDs and their associated health care services and medical expenses in Korea was investigated. METHODS: We included all AIRD cases reported between January 2016 and February 2021 based on the National Health Insurance Service data. We evaluated changes in incidence trends for each AIRD before and after NPI implementation (Feb 2020 to Feb 2021) using segmented regression analysis. Changes in health care utilization and medical costs for each AIRD before and after NPI implementation were also investigated. RESULTS: After NPI implementation, monthly incidence rates declined significantly by 0.205 per 1 000 000 (95% confidence interval [CI], -0.308 to -0.101, p < .001) in patients with systemic lupus erythematosus (SLE). No significant changes in the incidence of all AIRDs other than SLE were observed before and after implementation. Further, annual outpatient department visits per patient were lower during implementation for all diseases, except juvenile idiopathic arthritis (JIA). The prescription days per outpatient visit increased significantly during implementation for all diseases, except JIA and ankylosing spondylitis. During implementation, the total annual medical costs per patient tended to decrease for all diseases, except JIA and mixed connective tissue disease. CONCLUSION: Implementation of NPIs to contain the pandemic led to a reduction in the incidence of SLE and changed patterns of medical care utilization and treatment cost for most AIRDs.

The state of integrated disease surveillance globally: synthesis report of a mixed methods study.

OBJECTIVES: Disease surveillance is an essential public health function needed to prevent, detect, monitor and respond to health threats. Integrated disease surveillance (IDS) enhances its utility and has been advocated for decades by the World Health Organization. This study sought to examine the state of IDS implementation worldwide. STUDY DESIGN: The study used a concurrent mixed methods approach consisting of a systematic scoping review of the literature on IDS, a survey of International Association of National Public Health Institutes (IANPHI) members and qualitative deep dive case studies in seven countries. METHODS: This report collates, analyses and synthesises the findings from the three components. The scoping review consisted of a review of summarised evidence on IDS. Eight reviews and five primary studies were included. The cross-sectional survey was conducted of 110 IANPHI members representing ninety-five countries. Qualitative case studies were conducted in Malawi, Mozambique, Uganda, Pakistan, Canada, Sweden, and England, which involved thirty-four focus group discussions and forty-eight key informant interviews. RESULTS: In the different countries, IDS is conceptualised differently and there are differing levels of maturity of IDS functions. Although the role of National Public Health Institutes has not been well defined in the IDS, they play a significant role in IDS in many countries. Fragmentation between sectors and resourcing (human and financial) issues were common. Good governance measures such as appropriate legislative and regulatory frameworks and roles and responsibilities for IDS were often unclear. The COVID-19 pandemic has strengthened some surveillance systems, often through leveraging existing respiratory surveillance systems. In some instances, improvements were seen only for COVID-19 related data but these changes were not sustained. Evaluation of IDS was also reported to be weak. CONCLUSIONS: Integration should be driven by a clear purpose and contextualised. Political commitment, clear governance, and resourcing are needed. Technology and the establishment of technical communities of practice may help. However, the complexity and cost of integration should not be under-estimated, and further economic and impact evaluations of IDS are needed.

Caracterização do perfil sociodemográfico dos usuários de profilaxia pré-exposição ao HIV (PrEP) no Ceará / Characterization of the sociodemographic profile of users of hiv pre-exposure prophylaxis (PrEP) in Ceará

Introdução: a PrEP é uma estratégia de prevenção biomédica que consiste no uso de antirretrovirais (ARV) orais com o objetivo de mitigar o risco de adquirir o HIV e, consequentemente, de desenvolver a AIDS. O presente estudo tem como objetivo descrever o perfil sociodemográfico dos usuários com dispensação da PrEP no Ceará, no período de 2018 a 2023. Métodos: trata-se de um estudo transversal descritivo. Os dados foram obtidos por meio do Departamento de HIV/Aids, Tuberculose, Hepatites Virais e Infecções Sexualmente Transmissíveis (DATHI) do Ministério da Saúde por meio do Painel de monitoramento da PrEP. Resultados: observou-se um predomínio de usuários gays e homens que fazem sexo com homens, mas não se consideram gays; autodeclarados como pardos, com alta escolaridade e com faixa etária entre 30 e 39 anos. As dispensações da PrEP apresentaram progressão no período analisado, apesar dos anos de pandemia. Conclusão: embora a PrEP tenha-se mostrado eficaz no controle e declínio no número de infecções pelo HIV, esses dados demonstram que há uma lacuna entre quem se beneficia dela. É um desafio fazer com que a PrEP chegue a quem se pode beneficiar dela e com maior probabilidade de exposição ao HIV indivíduos de baixa escolaridade, pessoas trans, travestis, jovens adultos /adolescentes e não brancos.

Introduction: PrEP is a biomedical prevention strategy that consists of the use of oral antiretrovirals (ARV) to mitigate the risk of acquiring HIV and, consequently, of developing AIDS. The present study aims to describe the sociodemographic profile of users dispensed with PrEP in Ceará from 2018 to 2023. Methods: this is a descriptive cross-sectional study. The data was obtained from the Department of HIV/Aids, Tuberculosis, Viral Hepatitis, and Sexually Transmitted Infections (DATHI) of the Ministry of Health through the PrEP Monitoring Panel. Results: there was a predominance of Gay users and Men who have Sex with Men but do not consider themselves gay; they self-declared as mixed race, highly educated, and aged between 30 and 39 years old. PrEP dispensations showed progression in the period analyzed despite years of pandemic. Conclusion: although PrEP is effective in controlling and declining the number of HIV infections, these data demonstrate that there is a gap between who benefits from it. It is a challenge to make PrEP reach those who can most benefit from it and who are most likely to be exposed to HIV, individuals with low education, trans people, transvestites, young adults/adolescents, and non-whites.

Evaluation by community health agents of the attributes of primary health care for fighting leprosy: a cross-sectional study

OBJECTIVE: To evaluate whether the attributes of Primary Healthcare are present in leprosy control actions in Londrina from Community Health Workers' (CHW) perspectives. METHOD: Observational and evaluative study. Data collection occurred between January and March 2020 in Londrina, Paraná, using the questionnaire "Primary Care Assessment Tool (PCATool) - Hansen's disease - CHW version" and a population-based census of 246 CHWs from 52 Primary Healthcare Units. The analyses used a cutoff point (≥ 6.6), central tendency, and dispersion measures. One-way ANOVA and Tukey's post hoc tests were used to analyze differences. Results: The general performance towards the primary healthcare attributes were evaluated as strong (mean = 6.95 / SD = 1.08) and the essential score (mean = 7.39 / SD = 1.0). On the other hand, the derived score was evaluated as poor (mean = 6.07 / sd = 1.06). Concerning the Access attribute, the rural zone had a lower score than the urban (mean = 4.47 / SD = 1.63). Conclusion: The study highlights issues that can be improved, such as first contact access, catalog of services offered to leprosy patients, information provided to the community, professional training, and differences in PHC performance between urban and rural regions.

Individual perceptions of community efficacy for non-communicable disease management in twelve communities in China: cross-sectional and longitudinal analyses.

OBJECTIVES: This objective of this study was to use empirical data to assess cross-sectional variation singular and changes over time in community efficacy for non-communicable diseases (NCDs) management (COEN) and to examine individual factors associated with changes in COEN. STUDY DESIGN: This was a longitudinal observational study. METHODS: Participants with hypertension and diabetes were randomly selected from 12 communities from three cities in eastern China, and a baseline survey and a 1-year follow-up were conducted. The COEN scale has five dimensions: community physical environment (CPE), behavioral risk factors (BRF), mental health and social relationships (MHSR), community health management (CHM), and community organisations and activities (COA). Mixed-effects models were used to investigate the change in COEN over time and the association between individual factors and changes in COEN. RESULTS: COEN scores showed significant variation singular among the 12 communities (P < 0.001) at the baseline. In the mixed-effects model, CPE (ß coefficient: 1.62, P < 0.001), BRF (0.90, P < 0.001), MHSR (0.86, P < 0.001), CHM (0.46, P < 0.001), and total scores (ß = 3.57, P < 0.001) increased significantly over time. The changes in COEN were associated with individual characteristics (e.g., older, men, more educated). CONCLUSIONS: Cross-sectional variations and changes over time in COEN demonstrated the utility of a sensitive instrument. Factors such as age, gender, marriage, education level, and employment may affect the financial and social resources assignment for NCD management. Our findings suggest that further high-quality studies are needed to better evaluate the effect of community empowerment on the prevention and control of NCDs.

Percepções da dengue na perspectiva de uma comunidade rural da costa caribenha na Colômbia / Perceptions of dengue fever from the perspective of a rural community on the Caribbean coast in Colombia / Percepciones del dengue desde la perspectiva de una comunidad rural de la costa Caribe en Colombia

O estudo buscou compreender as percepções sobre a dengue em uma comunidade rural de Córdoba, Colômbia, com o objetivo de orientar ações específicas de enfermagem comunitária voltadas para o cuidado e a educação em saúde de pessoas, famílias e comunidades rurais. Foram realizadas 20 entrevistas semiestruturadas com chefes de família (13 homens e 7 mulheres), selecionados com base nos critérios de serem membros da comunidade há mais de 20 anos, se autoidentificarem como camponeses e terem no mínimo 18 anos de idade. O número de participantes foi determinado após alcançar a saturação teórica. As entrevistas foram transcritas e organizadas em uma matriz de análise para codificação, categorização e análise dos dados. Os achados revelaram três categorias analíticas: busca pelo conhecimento sobre a doença, práticas in situ e cuidados do passado e do presente. As famílias entrevistadas possuem conhecimento básico sobre a doença e o vetor causador, mantendo práticas familiares relacionadas ao uso de plantas medicinais para cuidados familiares e automedicação nas fases iniciais, devido à baixa percepção do risco. As famílias camponesas constroem representações socioculturais baseadas em solidariedade, apoio familiar e respeito pelo conhecimento dos idosos. A enfermagem é apresentada como ator essencial na coleta de práticas de cuidado para a elaboração e aplicação de planos de cuidado contextualizados de acordo com as necessidades do território. A pesquisa foi aprovada com o código SI-FCS-02-22, autorizando sua implementação.

The study sought to understand perceptions about dengue fever in a rural community in Córdoba, Colombia, with the aim of guiding specific community nursing actions aimed at health care and education for people, families and rural communities. 20 semi-structured interviews were carried out with heads of families (13 men and 7 women), selected based on the criteria of being members of the community for more than 20 years, self-identifying as peasants and being at least 18 years of age. The number of participants was determined after reaching theoretical saturation. The interviews were transcribed and organized into an analysis matrix for coding, categorization and data analysis. The findings revealed three analytical categories: search for knowledge about the disease, in situ practices and past and present care. The families interviewed have basic knowledge about the disease and the causative vector, maintaining family practices related to the use of medicinal plants for family care and self-medication in the early stages, due to low risk perception. Peasant families build sociocultural representations based on solidarity, family support and respect for the knowledge of the elderly. Nursing is presented as an essential actor in the collection of care practices for the elaboration and application of care plans contextualized according to the needs of the territory. The research was approved with code SI-FCS-02-22, authorizing its implementation.

La investigación fue aprobada con el código SI-FCS-02-22, a partir del cual se autoriza su implementación.

Dynamically adjustable SVEIR(MH) model of multiwave epidemics: Estimating the effects of public health measures against COVID-19.

The COVID-19 pandemic was characterized by multiple subsequent, overlapping outbreaks, as well as extremely rapid changes in viral genomes. The information about local epidemics spread and the epidemic control measures was shared on a daily basis (number of cases and deaths) via centralized repositories. The vaccines were developed within the first year of the pandemic. New modes of monitoring and sharing of epidemic data were implemented using Internet resources. We modified the basic SEIR compartmental model to include public health measures, multiwave scenarios, and the variation of viral infectivity and transmissibility reflected by the basic reproduction number R0 of emerging viral variants. SVEIR(MH) model considers the capacity of the medical system, lockdowns, vaccination, and changes in viral reproduction rate on the epidemic spread. The developed model uses daily infection reports for assessing the epidemic dynamics, and daily changes of mobility data from mobile phone networks to assess the lockdown effectiveness. This model was deployed to six European regions Baden-Württemberg (Germany), Belgium, Czechia, Lombardy (Italy), Sweden, and Switzerland for the first 2 years of the pandemic. The correlation coefficients between observed and reported infection data showed good concordance for both years of the pandemic (ρ = 0.84-0.94 for the raw data and ρ = 0.91-0.98 for smoothed 7-day averages). The results show stability across the regions and the different epidemic waves. Optimal control of epidemic waves can be achieved by dynamically adjusting epidemic control measures in real-time. SVEIR(MH) model can simulate different scenarios and inform adjustments to the public health policies to achieve the target outcomes. Because this model is highly representative of actual epidemic situations, it can be used to assess both the public health and socioeconomic effects of the public health measures within the first 7 days of the outbreak.

The state of integrated disease surveillance in seven countries: a synthesis report.

OBJECTIVES: Integrated disease surveillance (IDS) offers the potential for better use of surveillance data to guide responses to public health threats. However, the extent of IDS implementation worldwide is unknown. This study sought to understand how IDS is operationalized, identify implementation challenges and barriers, and identify opportunities for development. STUDY DESIGN: Synthesis of qualitative studies undertaken in seven countries. METHODS: Thirty-four focus group discussions and 48 key informant interviews were undertaken in Pakistan, Mozambique, Malawi, Uganda, Sweden, Canada, and England, with data collection led by the respective national public health institutes. Data were thematically analysed using a conceptual framework that covered governance, system and structure, core functions, finance and resourcing requirements. Emerging themes were then synthesised across countries for comparisons. RESULTS: None of the countries studied had fully integrated surveillance systems. Surveillance was often fragmented, and the conceptualization of integration varied. Barriers and facilitators identified included: 1) the need for clarity of purpose to guide integration activities; 2) challenges arising from unclear or shared ownership; 3) incompatibility of existing IT systems and surveillance infrastructure; 4) workforce and skills requirements; 5) legal environment to facilitate data sharing between agencies; and 6) resourcing to drive integration. In countries dependent on external funding, the focus on single diseases limited integration and created parallel systems. CONCLUSIONS: A plurality of surveillance systems exists globally with varying levels of maturity. While development of an international framework and standards are urgently needed to guide integration efforts, these must be tailored to country contexts and guided by their overarching purpose.

Factors associated with unsuccessful treatment outcome for tuberculosis in previously treated patients in Cali, Colombia, during the period 2015-2019 / Factores asociados al tratamiento no exitoso para tuberculosis en pacientes previamente tratados en Cali, Colombia, en el periodo 2015-2019

Introduction. The success rates in the treatment of tuberculosis are suboptimal. Objective. To identify associated factors with the lack of success of antituberculosis treatment in patients with a tuberculosis treatment history. Materials and methods. We performed a retrospective, analytical, observational, and cohort study of patients reentering the Mycobacterium program in Cali, Colombia. We included patients over 15 years old with pulmonary tuberculosis between 2015 and 2019 and a history of tuberculosis treatment. Patients with drug-resistant tuberculosis were excluded. Results. A total of 605 patients with a treatment history were included, 60% due to unfinished treatment and 40% due to relapse. Compared to patients reentering due to relapse (ORa=2.34, CI=1.62-3.38), the independent variables associated with treatment failure at discharge were homelessness (ORa=2.45, CI=1.54-3.89), substance dependence (ORa=1.95, CI=1.24-3.05), tuberculosis/HIV coinfection (ORa=1.69, CI=1.00-2.86), diabetes (ORa=1.89, CI=1.29-2.77), and unfinished previous tuberculosis treatment due to follow-up loss, abandonment, or other causes. Programmatic variables favoring treatment success were voluntary HIV testing counseling (p<0.001) and HIV testing (p<0.001). Conclusion. Homelessness, substance dependence, tuberculosis/HIV coinfection, diabetes, and incomplete previous treatment due to loss to follow-up, abandonment, or treatment failure hindered the success of antituberculosis. These characteristics should be identified and addressed during the initial care of patients reentering treatment for tuberculosis.

Introducción. Las tasas de éxito del tratamiento de la tuberculosis continúan siendo subóptimas. Objetivo. Identificar los factores asociados al tratamiento no exitoso para tuberculosis en pacientes con antecedentes de tratamiento para la tuberculosis. Materiales y métodos. Se realizó un estudio observacional retrospectivo, analítico, de cohorte de pacientes que reingresaron a un programa de micobacterias en Cali, Colombia. Se incluyeron mayores de 15 años con tuberculosis pulmonar entre el 2015 y el 2019 con antecedentes de tratamiento para la tuberculosis. Se excluyeron los pacientes con tuberculosis resistente. Resultados. Ingresaron 605 pacientes con antecedentes de tratamiento, 60 % por tratamiento inconcluso y 40 % por recaída. En comparación con los pacientes que reingresaron por recaída (ORa= 2,34; IC=1,62-3,38), las variables que explicaron de manera independiente el no tener éxito con el tratamiento para la tuberculosis al egreso fueron: estar en situación de calle (ORa = 2,45; IC = 1,54-3,89), ser farmacodependiente (ORa = 1,95; IC=1,24-3,05), tener coinfección tuberculosis/VIH (ORa = 1,69; IC =1,00-2,86) o diabetes (ORa =1,89; IC=1,29-2,77), y el incumplimiento de un tratamiento previo por pérdida de seguimiento, abandono u otras causas. Las variables programáticas que favorecieron el éxito del tratamiento fueron la asesoría de la prueba voluntaria de VIH (p <0,001) y la realización de la prueba de VIH (p < 0,001). Conclusión. Estar en situación de calle, ser farmacodependiente, tener coinfección de tuberculosis y VIH, o diabetes, así como el incumplimiento del tratamiento previo por pérdida del seguimiento, abandono o fracaso del mismo, dificultaron el éxito del tratamiento antituberculoso. En la primera atención al reingreso de los pacientes con tuberculosis se deben identificar y abordar estas características.

Lessons from the re-emergence of imported measles cases following the COVID-19 pandemic in Victoria, Australia.

Introduction: Australia was declared to have eliminated endemic measles in 2014; however, imported cases continue to pose a threat of outbreaks. International travel restrictions during the coronavirus disease 2019 (COVID-19) pandemic led to a rapid decline in measles cases. The re-opening of the Australian international border to measles endemic regions returns the threat of outbreaks, which may be further compounded by disruptions in routine vaccinations during the COVID-19 pandemic. We consider lessons learned from the public health response to recent measles cases. Methods: This case series includes all confirmed measles cases meeting the national case definition reported to the Victorian Government Department of Health (the Department) between 1 January and 31 December 2022. The Department conducted active case finding and contact tracing of all cases in line with national guidelines. Cases were descriptively analysed. Results: In 2022, six of the seven measles cases reported in Australia occurred in Victoria, all of whom resided in Australia and acquired their infection overseas. Three cases were unlinked, and three formed an epidemiologically-linked household cluster. One case was partially vaccinated, one was not eligible for vaccination, one had unknown vaccination status, and three were unvaccinated, one of whom was under 12 months old but would have been eligible for vaccination prior to travel to endemic regions. None of the cases led to secondary transmission within Australia. Discussion: Following the COVID-19 pandemic, measles importations have re-commenced in Victoria. Although few measles cases occurred in 2022 and none resulted in onwards transmission, imported measles cases remain complex and require substantial public health follow-up. Delays in case diagnosis and flight contact tracing pose a significant risk for outbreaks of measles. Public health interventions are needed to maintain high vaccination rates, improve contact tracing, and ensure public health authorities and healthcare providers can rapidly identify and respond to imported measles cases.

Socioeconomic disadvantage and engagement with digital contact tracing for COVID-19 in Western Sydney: A secondary analysis of surveillance data.

OBJECTIVE: COVID-19 outcomes were highly inequitably distributed in Australia and worldwide. The digitalisation of public health interventions offers resource-efficiency and increased capacity for pandemic responses, but risks excluding the elderly and disadvantaged, reinforcing existing inequalities. Despite this, there has been little evaluation of the determinants of uptake of digital contact tracing. This paper describes the use of digital contact tracing for COVID-19 in a population in metropolitan Sydney and the determinants of engagement in this population. METHODS: Routinely collected surveillance data for residents of Western Sydney Local Health District, returning a positive SARS-CoV-2 result between 1st August 2021 and 12th February 2022, were extracted including responses to a digital contact tracing questionnaire. Individual records were linked to area-level socioeconomic indices of disadvantage. Descriptive analyses explored characteristics of non-responders and geospatial variation. Logistic regression was undertaken to evaluate the effect of age, sex and socioeconomic disadvantage on the odds of response. RESULTS: Of the 133 055 individuals included, 130 645 (98%) were issued a digital contact tracing questionnaire, and 106 432 (81%) responded. Odds of responding were lower in males (odds ratio: 0.79), individuals aged 80+ (odds ratio: 0.17) and the most disadvantaged communities (odds ratio: 0.32). CONCLUSIONS: Digital data collection for contact tracing was a scalable and efficient tool in the context of the Western Sydney Local Health District COVID-19 response. However, older people and individuals in disadvantaged communities were less likely to engage. IMPLICATIONS FOR PUBLIC HEALTH: Responses to future pandemics should leverage the resource-efficiency of digital interventions but should avoid compounding existing health inequalities.

Integrated control of neglected tropical diseases in Brazil: document review of a national campaign in light of WHO recommendations.

Objective: To describe the results of a national campaign aimed at the integrated control of neglected tropical diseases in Brazil in light of the World Health Organization (WHO) official documentation related to the integration of strategies for the prevention, control, and elimination or eradication of neglected tropical diseases. Methods: A document review that included official WHO documents published between 2007 and 2020 and campaign results extracted from the official technical report produced by the Brazilian Ministry of Health. Results: The integrated control of neglected tropical diseases was gradually incorporated in the WHO documentation over time. Preventive chemotherapy through mass drug administration, intensified case management, and integrated vector management were extensively recommended as strategies for integrated control. The Brazilian campaign was carried out in four iterations between 2013 and 2017. Children aged 5 to 14 years enrolled in municipal public schools nationwide were targeted. In summary, a total of 1 074 and 73 522 new cases of leprosy and trachoma, respectively, were detected. Nearly 18 million doses of preventive chemotherapy for soil-transmitted helminthiasis were administered. More than 700 cases of schistosomiasis were diagnosed and treated. Conclusions: The integrated strategies implemented in Brazil throughout the campaign generated results aligned with the WHO recommendations for the control of neglected tropical diseases, especially those regarding mass drug administration, active case detection, and intensified case management. Therefore, the continuity of the campaign with adequate evaluation tools must be encouraged as a constant public health policy in the Brazilian government agenda.

Estrategias de control de la Equinococosis quística en el Uruguay / Strategies for the control of cystic echinococcosis in Uruguay / Estratégias de controle da equinococose cística no Uruguai

La equinococosis quística es una zoonosis de origen parasitario con distribución cosmopolita. En nuestro país continúa siendo una enfermedad endémica, afectando principalmente pequeños centros poblados y áreas rurales pobres relacionadas a la producción ovina. Los planes de control requieren de un abordaje holístico, con la participación de diferentes instituciones, profesionales y en especial de la comunidad. La cooperación regional busca monitorizar el avance de la enfermedad y centrar las medidas de acción sobre cuatro ejes, definidos según los puntos de intervención más comunes para la quiebra del ciclo de transmisión y la consecuente reducción en incidencia y prevalencia de la enfermedad. La presente revisión utilizó literatura obtenida en diferentes bases de datos, bibliotecas virtuales y sitios web regionales y locales con el objetivo describir las principales estrategias de control, vigilancia y prevención aplicadas actualmente en nuestro país.

Cystic echinococcosis is a zoonosis of parasitic origin with cosmopolitan distribution. In our country it continues to be an endemic disease, affecting mainly small population centers and poor rural areas related to sheep production. Control plans require a holistic approach, with the participation of different institutions, professionals and especially the community. Regional cooperation seeks to monitor the progress of the disease and focus action measures on four axes, defined according to the most common points of intervention to break the transmission cycle and consequently reduce the incidence and prevalence of the disease. This review used literature obtained from different databases, virtual libraries and regional and local websites with the aim of describing the main control, surveillance and prevention strategies currently applied in our country.

Factores asociados al tratamiento no exitoso para tuberculosis en pacientes previamente tratados en Cali, Colombia, en el periodo 2015-2019 / Factors associated with unsuccessful treatment outcome for tuberculosis in previously treated patients in Cali, Colombia, during the period 2015-2019

Introducción. Las tasas de éxito del tratamiento de la tuberculosis continúan siendo subóptimas. Objetivo. Identificar los factores asociados al tratamiento no exitoso para tuberculosis en pacientes con antecedentes de tratamiento para la tuberculosis. Materiales y métodos. Se realizó un estudio observacional retrospectivo, analítico, de cohorte de pacientes que reingresaron a un programa de micobacterias en Cali, Colombia. Se incluyeron mayores de 15 años con tuberculosis pulmonar entre el 2015 y el 2019 con antecedentes de tratamiento para la tuberculosis. Se excluyeron los pacientes con tuberculosis resistente. Resultados. Ingresaron 605 pacientes con antecedentes de tratamiento, 60 % por tratamiento inconcluso y 40 % por recaída. En comparación con los pacientes que reingresaron por recaída (ORa= 2,34; IC=1,62-3,38), las variables que explicaron de manera independiente el no tener éxito con el tratamiento para la tuberculosis al egreso fueron: estar en situación de calle (ORa = 2,45; IC = 1,54-3,89), ser farmacodependiente (ORa = 1,95; IC=1,24-3,05), tener coinfección tuberculosis/VIH (ORa = 1,69; IC =1,00- 2,86) o diabetes (ORa =1,89; IC=1,29-2,77), y el incumplimiento de un tratamiento previo por pérdida de seguimiento, abandono u otras causas. Las variables programáticas que favorecieron el éxito del tratamiento fueron la asesoría de la prueba voluntaria de VIH (p < 0,001) y la realización de la prueba de VIH (p < 0,001). Conclusión. Estar en situación de calle, ser farmacodependiente, tener coinfección de tuberculosis y VIH, o diabetes, así como el incumplimiento del tratamiento previo por pérdida del seguimiento, abandono o fracaso del mismo, dificultaron el éxito del tratamiento antituberculoso. En la primera atención al reingreso de los pacientes con tuberculosis se deben identificar y abordar estas características.

Introduction. The success rates in the treatment of tuberculosis are suboptimal. Objective. To identify associated factors with the lack of success of antituberculosis treatment in patients with a tuberculosis treatment history. Materials and methods. We performed a retrospective, analytical, observational, and cohort study of patients reentering the Mycobacterium program in Cali, Colombia. We included patients over 15 years old with pulmonary tuberculosis between 2015 and 2019 and a history of tuberculosis treatment. Patients with drug-resistant tuberculosis were excluded. Results. A total of 605 patients with a treatment history were included, 60% due to unfinished treatment and 40% due to relapse. Compared to patients reentering due to relapse (ORa=2.34, CI=1.62-3.38), the independent variables associated with treatment failure at discharge were homelessness (ORa=2.45, CI=1.54-3.89), substance dependence (ORa=1.95, CI=1.24-3.05), tuberculosis/HIV coinfection (ORa=1.69, CI=1.00-2.86), diabetes (ORa=1.89, CI=1.29-2.77), and unfinished previous tuberculosis treatment due to follow-up loss, abandonment, or other causes. Programmatic variables favoring treatment success were voluntary HIV testing counseling (p<0.001) and HIV testing (p<0.001). Conclusion. Homelessness, substance dependence, tuberculosis/HIV coinfection, diabetes, and incomplete previous treatment due to loss to follow-up, abandonment, or treatment failure hindered the success of antituberculosis. These characteristics should be identified and addressed during the initial care of patients reentering treatment for tuberculosis.

Leprosy and tuberculosis control scenario of the national program for the improvement of access and quality of primary care in Brazil.

BACKGROUND: In Brazil, despite advances in public health policies aimed at eliminating and controlling infectious and parasitic diseases, the incidence of neglected diseases is still high. The epidemiological scenario in Brazil of diseases such as tuberculosis and leprosy evidences a public policy agenda that has not been resolute in terms of control, nor in terms of elimination. OBJECTIVE: To analyze the actions of diagnosis and treatment of leprosy and tuberculosis in the context of primary health care. METHODS: In this ecological study, data from the third cycle of the Program for the Improvement of Access and Quality of Primary Care were extracted from electronic address of the Primary Health Care Secretariat of Brazil in the area of Actions, Programs and Strategies. A total of 37,350 primary health care teams were that answered the questionnaire were eligible, with variables extracted from leprosy and tuberculosis control actions. The municipalities were grouped according to the characteristic of the Brazilian municipality. The partition chi-square and the Residuals Test were used to assess whether there was a difference in the proportion of tuberculosis and leprosy actions between types of municipalities. Statistics were carried out using Minitab 20 and Bioestat 5.3. RESULTS: Regarding the leprosy treatment location, there is a higher proportion of people referred to be treated at the reference in adjacent rural (p = 0.0097) and urban (p < 0.0001) municipalities; monitoring of people with leprosy referred to the service network (p. = 0.0057) in remote rural areas. Lower proportion of teams requesting bacilloscopy in remote rural areas (p = 0.0019). Rural areas have a higher proportion of teams that diagnose new cases (p = 0.0004). Regarding the actions of diagnosis and treatment of tuberculosis. There is a higher proportion of teams that carry out consultations at the unit itself in rural areas when compared to adjacent intermediaries (p = 0.0099) and urban (p < 0.0001); who requested sputum smear microscopy in adjacent intermediaries (p = 0.0021); X-ray in adjacent intermediaries (p < 0.0001) and urban (p < 0.0001); collection of the first sputum sample in urban (p < 0.0001) and adjacent rural areas (p < 0.0001); directly observed treatment (p < 0.0001) in adjacent rural municipalities. CONCLUSION: There are inequalities in the diagnosis and treatment of leprosy and tuberculosis among the types of municipalities.
