Ámbito biológico, social, tecnológico, económico, normativo y político del plan hacia la eliminación de la malaria en el Perú 2022-2030 / Biological, social, technological, economic, regulatory and political scope of the plan towards the elimination of malaria in Peru 2022-2030

La malaria es producida por parásitos del género Plasmodium y transmitida por Anopheles. Es considerada un problema de salud pública; a pesar de la reducción significativa de los casos, a nivel mundial, persisten tasas de morbi-mortalidad elevadas. En las Américas, recientemente, se registró brotes palúdicos importantes en seis países, el Perú fue uno de ellos, generando la iniciativa para crear el Plan hacia la Eliminación de la Malaria en el Perú (PEMP), partiendo de la experiencia en el Departamento de Loreto en marco del Plan Malaria Cero. El PEMP, tiene la finalidad de reducir el 90% los casos de malaria antes de 2030, con un enfoque comunitario. El objetivo de este estudio fue evaluar la integralidad del PEMP referidas a los ámbitos biológico, social, tecnológico, económico, normativo y político. Se conformó un grupo de expertos, quienes realizaron la validez aparente de cada uno de los conceptos (DDP< 2,4). Posteriormente, la congruencia de causas por ámbitos y, la contribución por objetivos específicos dentro de cada ámbito. Encontrándose coherencias entre los objetivos específicos, planes y/o acciones dentro de cada ámbito. Se corroboró el enfoque integral del PEMP, encaminando en trabajo multidisciplinario y de comprensión integral de los desafíos actuales para la eliminación de la malaria. Se identifica como debilidad la falta de abordaje de los reservorios de malaria; se recomienda realizar búsqueda activa de casos e investigaciones en hospedadores no humano, especialmente en zonas de alta transmisión; e implementarse un diseño de enfoque holístico como parte del abordaje integral(AU)

Malaria is produced by parasites of the genus Plasmodium and transmitted by Anopheles. It is considered a public health problem; Despite the significant reduction in cases, worldwide, high morbidity and mortality rates persist. In the Americas, important malaria outbreaks were recently registered in six countries, Peru was one of them, generating the initiative to create the Plan for the Elimination of Malaria in Peru (PEMP), based on the experience in the Department of Loreto within the framework of the Zero Malaria Plan. The PEMP aims to reduce malaria cases by 90% before 2030, with a community approach. The objective of this study was to evaluate the integrality of the PEMP referring to the biological, social, technological, economic, regulatory and political fields. A group of experts was formed, who carried out the apparent validity of each one of the concepts (DDP < 2.4). Subsequently, the congruence of causes by areas and the contribution by specific objectives within each area. Finding coherence between the specific objectives, plans and/or actions within each area. The integral approach of the PEMP was confirmed, leading to multidisciplinary work and a comprehensive understanding of the current challenges for the elimination of malaria. The lack of approach to malaria reservoirs is identified as a weakness; It is recommended to carry out active search for cases and investigations in non-human hosts, especially in areas of high transmission; and a holistic approach design implemented as part of the comprehensive approach(AU)

A systematic literature review on the economic impact of endemic disease in UK sheep and cattle using a One Health conceptualisation.

Endemic sheep and cattle diseases represent a constant strain and impact to animal health and welfare, the environment, public health, and the economy. Quantifying this impact helps to inform decisions on surveillance and control of livestock diseases. This systematic literature review had two objectives; to describe the economic impact of endemic sheep and cattle diseases in the United Kingdom using a broad conceptualisation of impact, and to investigate what variables (e.g. medication costs, loss of production) and methods are included in these calculations. The Prisma protocol for systematic literature reviews was followed. Searches were performed in Pubmed, Scopus and Web of Science using selected and trialled search terms. A total of 1129 papers were identified and screened for relevancy; 38 papers were selected for full review extracting and analysing data on disease, impact and methods. From this final selection of papers it was found that; 1) research in this area is mainly focused on the dairy sub-sector, 2) the most mentioned diseases were mastitis and lameness in dairy cattle; bovine viral diarrhoea in beef cattle; and ectoparasites in sheep with reported animal-level costs of £ 77-£ 548/cow/year, £ 26-£ 185/bovine animal/year and £ 40-£ 47/ewe/year, respectively, 3) numerous methods and variables were used to calculate or estimate the economic impact with most studies focussing on the direct producer impacts and less on the wider implications and affected stakeholders; and 4) it was common for studies to look at one disease in isolation rather than consider disease impact on the farm as a whole. It is recommended that future economic impact calculations on livestock disease include wider implications to estimate the true cost of disease. To generate the necessary data, a wider, more inclusive conceptualisation of impact will be needed to support the collection of data and facilitate communication between stakeholders. Systematic health data recording combined with assessment calculations and metrics that allow comparability within or across livestock sub-sectors will increase the informative value of these impact calculations.

Combining epidemiology and economics to assess control of a viral endemic animal disease: Porcine Reproductive and Respiratory Syndrome (PRRS).

Porcine reproductive and respiratory syndrome (PRRS) is an extremely contagious disease that causes great damage to the U.S. pork industry. PRRS is not subject to official control in the U.S., but most producers adopt control strategies, including vaccination. However, the PRRS virus mutates frequently, facilitating its ability to infect even vaccinated animals. In this paper we analyze how increased vaccination on sow farms reduces PRRS losses and when vaccination is profitable. We develop a SIR model to simulate the spread of an outbreak between and within swine farms located in a region of Minnesota. Then, we estimate economic losses due to PRRS and calculate the benefits of vaccination. We find that increased vaccination of sow farms increases the private profitability of vaccination, and also transmits positive externalities to farms that do not vaccinate. Although vaccination reduces industry losses, a low to moderate vaccine efficacy implies that large PRRS losses remain, even on vaccinated farms. Our approach provides useful insight into the dynamics of an endemic animal disease and the benefits of different vaccination regimens.

The cost of tsetse control using 'Tiny Targets' in the sleeping sickness endemic forest area of Bonon in Côte d'Ivoire: Implications for comparing costs across different settings.

BACKGROUND: Work to control the gambiense form of human African trypanosomiasis (gHAT), or sleeping sickness, is now directed towards ending transmission of the parasite by 2030. In order to supplement gHAT case-finding and treatment, since 2011 tsetse control has been implemented using Tiny Targets in a number of gHAT foci. As this intervention is extended to new foci, it is vital to understand the costs involved. Costs have already been analysed for the foci of Arua in Uganda and Mandoul in Chad. This paper examines the costs of controlling Glossina palpalis palpalis in the focus of Bonon in Côte d'Ivoire from 2016 to 2017. METHODOLOGY/PRINCIPAL FINDINGS: Some 2000 targets were placed throughout the main gHAT transmission area of 130 km2 at a density of 14.9 per km2. The average annual cost was USD 0.5 per person protected, USD 31.6 per target deployed of which 12% was the cost of the target itself, or USD 471.2 per km2 protected. Broken down by activity, 54% was for deployment and maintenance of targets, 34% for tsetse surveys/monitoring and 12% for sensitising populations. CONCLUSIONS/SIGNIFICANCE: The cost of tsetse control per km2 of the gHAT focus protected in Bonon was more expensive than in Chad or Uganda, while the cost per km2 treated, that is the area where the targets were actually deployed, was cheaper. Per person protected, the Bonon cost fell between the two, with Uganda cheaper and Chad more expensive. In Bonon, targets were deployed throughout the protected area, because G. p. palpalis was present everywhere, whereas in Chad and Uganda G. fuscipes fuscipes was found only the riverine fringing vegetation. Thus, differences between gHAT foci, in terms of tsetse ecology and human geography, impact on the cost-effectiveness of tsetse control. It also demonstrates the need to take into account both the area treated and protected alongside other impact indicators, such as the cost per person protected.

Distribution and health-ecological risk assessment of heavy metals: an endemic disease case study in southwestern China.

This research focuses on the health risks caused by heavy metal (HM) environmental pollution. Soil, water, corn, rice, and patients' hair samples from Daping Village, Yunnan Province, China, were analyzed for seven selected HMs. Geoaccumulation index (Igeo), pollution indexes (PI), and the Nemerow integrated pollution index (PN) were used to evaluate pollution levels. We employed principal component analysis (PCA), correlation analysis (CA), and spatial distribution to identify the source and distribution characteristics of HMs in soil. Health risks of HMs and exposure pathways were accessed by calculating the hazard quotient (HQ) and hazard index (HI). The Igeo, PI, and PN results show that cadmium (Cd) and arsenic (As) pollution is severe in soil, while other pollution is relatively little. PCA, CA, and spatial distribution show that HMs may be derived from black shale weathering and enrichment. Residents' drinking water is relatively safe. Arsenic is the element most threatening to local residents (HI = 3.8). Soil (HI = 3.55) ingestion and plant (HI = 1.67) ingestion are the primary exposure pathways to HMs. This unusual disease may be caused by children's relatively low immunity and long-term exposure to As. We must enhance the protection of children and encourage avoiding soil contact as much as possible. Our results highlight the importance of investigating HM pollution from geological sources and blocking potential exposure pathways.

When and why direct transmission models can be used for environmentally persistent pathogens.

Variants of the susceptible-infected-removed (SIR) model of Kermack & McKendrick (1927) enjoy wide application in epidemiology, offering simple yet powerful inferential and predictive tools in the study of diverse infectious diseases across human, animal and plant populations. Direct transmission models (DTM) are a subset of these that treat the processes of disease transmission as comprising a series of discrete instantaneous events. Infections transmitted indirectly by persistent environmental pathogens, however, are examples where a DTM description might fail and are perhaps better described by models that comprise explicit environmental transmission routes, so-called environmental transmission models (ETM). In this paper we discuss the stochastic susceptible-exposed-infected-removed (SEIR) DTM and susceptible-exposed-infected-removed-pathogen (SEIR-P) ETM and we show that the former is the timescale separation limit of the latter, with ETM host-disease dynamics increasingly resembling those of a DTM when the pathogen's characteristic timescale is shortened, relative to that of the host population. Using graphical posterior predictive checks (GPPC), we investigate the validity of the SEIR model when fitted to simulated SEIR-P host infection and removal times. Such analyses demonstrate how, in many cases, the SEIR model is robust to departure from direct transmission. Finally, we present a case study of white spot disease (WSD) in penaeid shrimp with rates of environmental transmission and pathogen decay (SEIR-P model parameters) estimated using published results of experiments. Using SEIR and SEIR-P simulations of a hypothetical WSD outbreak management scenario, we demonstrate how relative shortening of the pathogen timescale comes about in practice. With atttempts to remove diseased shrimp from the population every 24h, we see SEIR and SEIR-P model outputs closely conincide. However, when removals are 6-hourly, the two models' mean outputs diverge, with distinct predictions of outbreak size and duration.

Selectively recommend 18F-FDG PET/CT for patients with de novo nasopharyngeal carcinoma in endemic areas.

INTRODUCTION: To identify the subset of patients with de novo nasopharyngeal carcinoma (NPC) for whom [18F] fluorodeoxyglucose positron emission tomography and computed tomography (18F-FDG PET/CT) should be recommended, and to determine whether PET/CT is a cost-effective decision for precise M staging in endemic areas. MATERIALS AND METHODS: Retrospective analysis of data of 4469 patients diagnosed with de novo NPC between January 2014 and December 2019. The detection rate of distant metastasis was compared between different groups. Univariate and multiple logistic regression analysis was applied to identify the risk factors for distant metastasis. The cost-effectiveness of the diagnostic strategies was assessed. RESULTS: The detection rate of distant metastasis in the whole cohort was 5.46%. In multivariate analysis, male sex, T3-4 stage, N2-3 stage, and high plasma Epstein-Barr virus (EBV) DNA (≥ 14,650 copies/mL) were risk factors for distant metastases. NPC patients with T3-4 stage combined with N2-3 stage, high EBV DNA combined with male sex, or N2-3 stage combined with high EBV DNA were defined as recommended group with relatively higher tendency for metastasis. Distant metastasis incidence in recommended group and unrecommended group were 10.25% and 1.75%, respectively (P < 0.001). In the recommended group, PET/CT significantly improved the detection rate of distant metastasis (13.25% vs 9.02%, P = 0.005). Cost-effectiveness analysis revealed that additional cost for every one percent increase in distant metastasis detection rate was $22,785.58 in the recommended group (< Willingness-to-pay (WTP) threshold of $32,700.00) and $310,912.90 in the unrecommended group. CONCLUSIONS: In patients with de novo NPC, the tendency for metastasis can be predicted based on clinical parameters. 18F-FDG PET/CT should be selectively recommended for the subset of patients with a relatively higher tendency for metastasis.

Metas 2030 para los programas de control de las geohelmintiasis

La hoja de ruta para las enfermedades tropicales desatendidas, publicada por la OMS en el 2012, estableció dos metas para el control de las geohelmintiasis para el 2020, a saber: suministrar tratamiento regular a 75% de los niños en edad preescolar y escolar que lo requirieran y lograr la cobertura de 75% con la quimioterapia preventiva en los niños en edad preescolar y escolar en 100% de los países. En el 2017, los datos recopilados de los 103 países donde las geohelmintiasis son endémicas mostraban que era factible alcanzar esas dos metas. En octubre del 2018, un grupo de representantes de esos países, junto con asociados de otras instituciones que apoyan las actividades de control, se reunió en Basilea para proponer nuevas metas que orientaran la quimioterapia preventiva y otras actividades de control una vez alcanzadas las metas para el 2020. Los indicadores establecidos por el grupo de trabajo y que se presentan en esta publicación pueden considerarse recomendaciones de los expertos dirigidas al Departamento de la OMS de Control de Enfermedades Tropicales Desatendidas, para distribuir a su vez a las oficinas regionales y en los países de la OMS, los funcionarios del ministerio de salud y los responsables de los programas en los países con endemicidad, a fin de sustentar la lista definitiva de los indicadores en materia de geohelmintiasis que deberán alcanzarse para el 2030.

Measuring endemicity and burden of leprosy across countries and regions: A systematic review and Delphi survey.

BACKGROUND: Leprosy is a chronic infectious disease caused by Mycobacterium leprae, the annual new case detection in 2019 was 202,189 globally. Measuring endemicity levels and burden in leprosy lacks a uniform approach. As a result, the assessment of leprosy endemicity or burden are not comparable over time and across countries and regions. This can make program planning and evaluation difficult. This study aims to identify relevant metrics and methods for measuring and classifying leprosy endemicity and burden at (sub)national level. METHODS: We used a mixed-method approach combining findings from a systematic literature review and a Delphi survey. The literature search was conducted in seven databases, searching for endemicity, burden and leprosy. We reviewed the available evidence on the usage of indicators, classification levels, and scoring methods to measure and classify endemicity and burden. A two round Delphi survey was conducted to ask experts to rank and weigh indicators, classification levels, and scoring methods. RESULTS: The literature review showed variation of indicators, levels, and cut-off values to measure leprosy endemicity and/or burden. The most used indicators for endemicity include new case detection rate (NCDR), new cases among children and new cases with grade 2 disability. For burden these include NCDR, MB cases, and prevalence. The classification levels 'high' and 'low' were most important. It was considered most relevant to use separate scoring methods for endemicity and burden. The scores would be derived by use of multiple indicators. CONCLUSION: There is great variation in the existing method for measuring endemicity and burden across countries and regions. Our findings contribute to establishing a standardized uniform approach to measure and classify leprosy endemicity and burden at (sub)national level, which would allow effective communication and planning of intervention strategies.

Differential mortality of infectious disease in Italian polities: COVID-19, past plague epidemics, and currently endemic respiratory disease.

Coronavirus disease 2019 (COVID-19) has harshly impacted Italy since its arrival in February 2020. In particular, provinces in Italy's Central and Northern macroregions have dealt with disproportionately greater case prevalence and mortality rates than those in the South. In this paper, we compare the morbidity and mortality dynamics of 16th and 17th century Plague outbreaks with those of the ongoing COVID-19 pandemic across Italian regions. We also include data on infectious respiratory diseases which are presently endemic to Italy in order to analyze the regional differences between epidemic and endemic disease. A Growth Curve Analysis allowed for the estimation of time-related intercepts and slopes across the 16th and 17th centuries. Those statistical parameters were later incorporated as criterion variables in multiple General Linear Models. These statistical examinations determined that the Northern macroregion had a higher intercept than the Southern macroregion. This indicated that provinces located in Northern Italy had historically experienced higher plague mortalities than Southern polities. The analyses also revealed that this geographical differential in morbidity and mortality persists to this day, as the Northern macroregion has experienced a substantially higher COVID-19 mortality than the Southern macroregion. These results are consistent with previously published analyses. The only other stable and significant predictor of epidemic disease mortality was foreign urban potential, a measure of the degree of interconnectedness between 16th and 17th century Italian cities. Foreign urban potential was negatively associated with plague slope and positively associated with plague intercept, COVID-19 mortality, GDP per capita, and immigration per capita. Its substantial contribution in predicting both past and present outcomes provides a temporal continuity not seen in any other measure tested here. Overall, this study provides compelling evidence that temporally stable geographical factors, impacting both historical and current foreign pathogen spread above and beyond other hypothesized predictors, underlie the disproportionate impact COVID-19 has had throughout Central and Northern Italian provinces.

"We know about schistosomiasis but we know nothing about FGS": A qualitative assessment of knowledge gaps about female genital schistosomiasis among communities living in Schistosoma haematobium endemic districts of Zanzibar and Northwestern Tanzania.

BACKGROUND: Schistosoma haematobium causes urogenital schistosomiasis and is widely distributed in Tanzania. In girls and women, the parasite can cause Female Genital Schistosomiasis (FGS), a gynecological manifestation of schistosomiasis that is highly neglected and overlooked by public health professionals and policy makers. This study explored community members' knowledge, attitudes and perceptions (KAP) on and health seeking behavior for FGS. METHODS/PRINCIPAL FINDINGS: Using qualitative research methods-including 40 Focus Group Discussions (FGDs) and 37 Key Informant Interviews (KIIs)-we collected data from 414 participants (Males n = 204 [49.3%] and Females n = 210 [50.7%]). The study engaged 153 participants from Zanzibar and 261 participants from northwestern Tanzania and was conducted in twelve (12) purposively selected districts (7 districts in Zanzibar and 5 districts in northwestern Tanzania). Most participants were aware of urogenital schistosomiasis. Children were reported as the most affected group and blood in urine was noted as a common symptom especially in boys. Adults were also noted as a risk group due to their involvement in activities like paddy farming that expose them to infection. Most participants lacked knowledge of FGS and acknowledged having no knowledge that urogenital schistosomiasis can affect the female reproductive system. A number of misconceptions on the symptoms of FGS and how it is transmitted were noted. Adolescent girls and women presenting with FGS related symptoms were reported to be stigmatized, perceived as having a sexually transmitted infection (STI), and sometimes labeled as "prostitutes". Health seeking behavior for FGS included a combination of traditional medicine, self-treatment and modern medicine. CONCLUSION/SIGNIFICANCE: Community members living in two very different areas of Tanzania exhibited major, similar gaps in knowledge about FGS. Our data illustrate a critical need for the national control program to integrate public health education about FGS during the implementation of school- and community-based mass drug administration (MDA) programs and the improvement of water, sanitation and hygiene (WASH) facilities.

Surmounting structural barriers to tackle endemic infectious diseases.

A unique experiment in bringing academic and industrial scientists together to tackle endemic infectious diseases has proved a success. The Tres Cantos Open Lab Foundation, guided and advised by independent experts, funds extended stays of academics at the campus of a pharmaceutical company, where they access the firm's resources in partnership with company scientists. Progress in tackling tuberculosis, protozoal infections, and enteric bacterial diseases has sustained the decade-long evolution of the model, whose distinctive features complement other public-private partnerships with similar goals.

Presentaciones inesperadas de enfermedades endémicas: síndrome de dificultad respiratoria aguda en un paciente con dengue / Unexpected presentations of endemic conditions: acute respiratory distress syndrome in a dengue patient

El dengue es la infección trasmitida por vectores con mayor impacto en carga de enfermedad, económica y social a nivel mundial, con más de 3,6 billones de personas en riesgo de infección. Sus manifestaciones son variables, caracterizadas en su mayoría por síndrome febril con riesgo de sangrado, choque y muerte. El compromiso pulmonar es infrecuente, siendo el síndrome de dificultad respiratoria aguda una complicación inesperada, aunque informada, asociada a un mal pronóstico. Se presenta un paciente sin antecedentes relevantes de importancia, con focalización pulmonar severa asociado a infección por el virus dengue. En el caso presentado se descartaron procesos infecciosos bacterianos u otros agentes causales de síndrome de dificultad respiratoria aguda, lo que sumado a las características clínicas de ingreso, zona de ocurrencia del caso considerada como endémica, curso clínico, paraclínico y la franca positividad de las pruebas para dengue así como la seroconversión de estas, a pesar de no haber sido realizadas pruebas moleculares, se consideró como el agente causal más probable el virus dengue. Todo esto lleva a recomendar siempre considerarlo como potencial agente causal, lo que permite así un diagnóstico y manejo óptimos(AU)

Dengue is the vector-borne infection with the greatest impact on disease, economic and social burden worldwide, with more than 3.6 billion people under risk of contagion. Its manifestations are varied, most of them characterized by febrile syndrome with a risk of bleeding, shock and death. Pulmonary involvement is infrequent, and acute respiratory distress syndrome is an unexpected complication, though it has been reported in association to a bad prognosis. A case is presented of a male patient without relevant antecedents of interest, with severe pulmonary focalization associated to dengue virus infection. Bacterial infectious processes and other causative agents of acute respiratory distress syndrome were ruled out. In view of the patient's clinical status at admission, the endemicity of the patient's area of residence, the clinical and paraclinical course, and the obvious positivity of the dengue tests performed and their seroconversion, despite not having conducted molecular tests, it was concluded that the most probable causative agent was dengue virus. Therefore, it is recommended that dengue infection always be considered as a potential causative agent of acute respiratory distress syndrome, thus contributing to optimal diagnosis and management(AU)

Nota Téccnica n. 98 (Disoc): Mortalidade por covid-19 e queda do emprego no Brasil e no mundo

Para situar no contexto mundial a intensidade relativa de danos causados pela covid-19 no Brasil, esta nota compara alguns indicadores, ressaltando suas principais limitações e vantagens. O Brasil registrou, em proporção de sua população total, mais mortes por covid-19 em 2020 do que 89,3% dos demais 178 países com dados compilados pela Organização Mundial de Saúde (OMS). Quando a comparação desses registros é ajustada à distribuição populacional por faixa etária e sexo em cada país, o resultado brasileiro se torna pior que os de 94,9% dos mesmos 178 países. Com base em dados de nível de ocupação compilados pela Organização Internacional do Trabalho (OIT), o Brasil registrou queda do indicador mais intensa do que as de 84,1% dos demais 63 países analisados entre os três últimos trimestres de 2019 e de 2020.

Epidemiological investigation and physician awareness regarding the diagnosis and management of Q fever in South Korea, 2011 to 2017.

BACKGROUND: In South Korea, the number of Q fever cases has rapidly increased since 2015. Therefore, this study aimed to characterize the epidemiological and clinical features of Q fever in South Korea between 2011 and 2017. METHODS/PRINCIPAL FINDINGS: We analyzed the epidemiological investigations and reviewed the medical records from all hospitals that had reported at least one case of Q fever from 2011 to 2017. We also conducted an online survey to investigate physicians' awareness regarding how to appropriately diagnose and manage Q fever. The nationwide incidence rate of Q fever was annually 0.07 cases per 100,000 persons. However, there has been a sharp increase in its incidence, reaching up to 0.19 cases per 100,000 persons in 2017. Q fever sporadically occurred across the country, with the highest incidences in Chungbuk (0.53 cases per 100,000 persons per year) and Chungnam (0.27 cases per 100,000 persons per year) areas. Patients with acute Q fever primarily presented with mild illnesses such as hepatitis (64.5%) and isolated febrile illness (24.0%), whereas those with chronic Q fever were likely to undergo surgery (41.2%) and had a high mortality rate (23.5%). Follow-up for 6 months after acute Q fever was performed by 24.0% of the physician respondents, and only 22.3% of them reported that clinical and serological evaluations were required after acute Q fever diagnosis. CONCLUSIONS: Q fever is becoming an endemic disease in the midwestern area of South Korea. Given the clinical severity and mortality of chronic Q fever, physicians should be made aware of appropriate diagnosis and management strategies for Q fever.
