Objetivos: descrever os aspectos epidemiológicos, espaciais e temporais da leishmaniose visceral humana, no município de Sobral, no período de 2007 a 2019. Métodos: foi realizado um estudo epidemiológico descritivo e ecológico de análise espacial e temporal, com uso dos programas Quantum-Gis e Joinpoint. Resultados: foram confirmados 316 casos novos, predominantemente, no sexo masculino, nas faixas etárias de 1 a 4 anos (26,3%) e de 20 a 39 anos (24,0%), na zona urbana. Febre (95,9%), fraqueza (85,1%), emagrecimento (80,1%), palidez (73,7%), esplenomegalia (75,6%) e hepatomegalia (69,3%) foram os sinais clínicos mais frequentes. A doença se concentrou em quatro bairros: Terrenos Novos, Centro, Expectativa e Sinhá Saboia, expressando áreas mais densas (quentes). A incidência e a letalidade foram crescentes no início do período e decrescentes no final, com uma inversão destes indicadores no ano de 2014. Conclusão: em Sobral, a leishmaniose visceral humana é um agravo considerado relevante para o serviço de vigilância em saúde com necessidade de intensificação das ações de controle entomológico, zoonótico e de manejo ambiental, principalmente nas áreas mais densas.

Objectives: the objective was to describe the epidemiological, spatial, and temporal aspects of human visceral leishmaniasis, in the municipality of Sobral, from 2007 to 2019. Methods: A descriptive, spatial and temporal ecological study was carried out using Quantum-Gis and Joinpoint programs. Results: 316 new cases were confirmed, predominantly in males, in the age groups of 1 to 4 years (26.3%) and 20 to 39 years (24.0%), mainly in the urban area. Fever (95.9%), weakness (85.1%), weight loss (80.1%), pallor (73.7%), splenomegaly (75.6%), and hepatomegaly (69.3%) were the most frequent clinical signs. The disease was concentrated in four neighborhoods (Terrenos Novos, Centro, Expectativa, and Sinhá Saboia), hot spots. The incidence and case-fatality increased at the beginning of the period but decreased at the end, with an inversion in these in the year 2014. Conclusion: In Sobral, human visceral leishmaniasis is a disease considered relevant to the health surveillance service, with the need to intensify entomological, zoonotic, and environmental management actions, especially in denser areas.

Epidemiological and clinical factors associated with lethality from Human Visceral Leishmaniasis in Northeastern Brazil, 2007 to 2018.

Human Visceral Leishmaniasis (HVL) presents a subacute clinical evolution with systemic involvement, which can result in high case fatality, especially among untreated individuals or those with low socioeconomic status. This study aimed to identify epidemiological and clinical factors associated with HVL case fatality in the Ceara State, from 2007 to 2018. This is an analytical cross-sectional study. The bivariate analysis was performed by Stata 15.1 using Pearson's Chi-square or Fisher's exact test; and Poisson regression for age-controlled multivariate analysis. From 2007 to 2018, there were 4,863 new confirmed cases and 343 deaths from HVL (case fatality rate=7.05%). The risk factors associated with case fatalities were: age group (RR=8.69; 95%CI:3.56-21.20); black population (RR=2.21; 95%CI:1.45-3.35); jaundice symptoms (RR=1.72; 95%CI:1.38-2.14); edema (RR=2.62; 95%CI:2.10-3.26) and hemorrhagic phenomena (RR=1.63; 95%CI:1.26-2.10); and no prescription drug intake (RR=4.03; 95%CI:2.98-5.46). Treatment with pentavalent antimonial was a protective factor (RR=0.35; 95%CI:0.27-0.45). The number of deaths increased among the elderly, illiterate, urban residents, and black skin color individuals. The drugs pentavalent antimonial and amphotericin B showed an association with death, but were not considered causal factors. Treatment failure led to a high risk of death. In multivariate analysis, the risk factors for fatal cases were age group, black skin, symptoms of jaundice, edema and hemorrhagic phenomena; and failure to take the prescription drugs. Treatment with pentavalent antimonial was shown to be a protective factor. Knowing the factors associated with the fatality of VL-HIV cases may help to improve public policies, in order to refine the epidemiological surveillance program and, consequently, prevent deaths related to the disease in Ceara.

Epidemiological Aspects and High Magnitude of Human Visceral Leishmaniasis in Ceará, Northeast of Brazil, 2007-2021.

BACKGROUND: Human visceral leishmaniasis HVL is endemic to 75 countries. The state of Ceará, the Northeast region of Brazil, is of great sanitary importance for the transmission of HVL, and it stands out as an area of interest for epidemiological aspects and control strategies. This study aimed to characterize HVL in relation to epidemiological aspects, composite incidence, and mortality rates in the state of Ceará, Brazil, from 2007 to 2021. METHODS: This ecological study used temporal and spatial cuts of HVL data from the notifiable diseases information system. Epidemiological indicators such as incidence, mortality, and composite indices of incidence and mortality were calculated according to the Ministry of Health standardization. RESULTS: There were 6,775 confirmed cases, with high incidence coefficients in 2009 6.96 cases/100,000 inhabitants and 2011 9.83 cases/100,000 inhabitants, and the highest mortality rate in 2011 6.96 deaths/100,000 inhabitants. The composite index of incidence and mortality identified municipalities in the Northern, Northwestern, and Southern regions of Ceará as having the highest risk of HVL. CONCLUSIONS: HVL remained endemic throughout the study period, with epidemiological indicators and risk of transmission expressing high magnitude, mainly in the Northeast, Northwest, and South regions of Ceará.

High Effectiveness of SARS-CoV-2 Vaccines in Reducing COVID-19-Related Deaths in over 75-Year-Olds, Ceará State, Brazil.

In Brazil, the SARS-CoV-2 vaccination program has so far prioritized people over 75 years of age. By the end of March 2021, in Ceará State, a total of 313,328 elderly people had received at least one dose of vaccine (45% Oxford-AstraZeneca/Fiocruz and 55% CoronaVac-Sinovac/Butantan), and 159,970 had received two doses (83% CoronaVac-Sinovac/Butantan and 17% Oxford-AstraZeneca/Fiocruz). After a single dose, there was already a significant reduction in COVID 19-related deaths (protection ratio: 19.31 (95% CI: 18.20-20.48), attributable protection ratio: 94.8%); higher protection ratios were observed after the application of two doses of the vaccine (132.67; 95% CI: 109.88-160.18), with an attributable protection ratio of 99.2%. SARS-CoV-2 vaccines are highly effective in reducing the number of COVID-19-related deaths in over 75-year-olds in Brazil, one of the hardest hit countries by the current pandemic.

Risk areas for Human Visceral Leishmaniosis 2007-2018: A temporal and spatial analysis in Ceará, Brazil.

Visceral leishmaniasis (VL) is considered as an important tropical disease because it rapidly spreads across a wide geographical area. This study aimed to analyse the temporal and spatial patterns of incidence, mortality and case fatality rates due to human VL in Ceará, Brazil, from 2007 to 2018. This is an ecological study involving time series and spatial analyses, and data were obtained from human VL notifications. Temporal trend analysis was carried out using the Joinpoint Regression Program. SaTScan 9.6 was used for conducting spatial analyses, and ArcMap 9.2 was used for building maps. There were 6,066 incident cases and 516 deaths due to human VL. There was an increasing trend in the incidence rate from 2007 to 2014 (annual per cent change [APC] = 3.8; 95% confidence interval [CI]:0.5 to 7.3; p = .031). Mortality (APC = -0.3; 95%CI: -2.5 to 1.9; p = .765) and VL case fatality rates (APC = -3.0; 95%CI: -4.3 to -1,7; p = .188) showed non-significant decline. The incidence rates were higher in the northwest and south regions of the state, with 11 high incidence rate clusters from 2007 to 2010, seven clusters in 44 municipalities from 2011 to 2014, and six clusters in 49 municipalities from 2015 to 2018. During 2007-2010, only one significant mortality rate cluster was identified in the southern region (relative risk [RR] = 7.6); during 2011-2014, two clusters in the northwest region were identified (RR=3.9 and RR=4.6). In the last period, a cluster of 11 municipalities in the southern region was identified (RR = 4.2). Mortality rate clusters were identified in the centre-south (2007-2010), northwest and south (both from 2011 to 2018). VL has a heterogeneous distribution, with maintenance of clusters with high incidence and mortality rates, as well as case fatality rates in municipalities in the northwest and south regions. These clusters present areas with the greatest risk of transmission of human VL.

Human visceral leishmaniasis: epidemiological, temporal and spacial aspects in Northeast Brazil, 2003-2017.

Visceral leishmaniasis is a highly lethal zoonosis transmitted by a sandfly. It is caused by a Leishmania protozoan parasite and dogs are the main reservoir. Ceara State is endemic to visceral leishmaniasis and it is considered a high risk transmission area. Temporal and spatial epidemiological studies have been used as tools to analyze the distribution and frequency of human visceral leishmaniasis (HVL). This study aimed to characterize HVL in its epidemiological andtemporal aspects in Ceara State, from 2003 to 2017, as this is a neglected disease and a public health problem. This is an ecological study carried out with HVL confirmed cases in Ceara, using three blocks of years (2003 to 2007, 2008 to 2012 and 2013 to 2017). The disease presented an endemic behavior, affecting mainly male residents in the urban area, especially children under five and young adults between 30 and 49 years old. HVL is recorded in all the municipalities, for more than 10 years, with a growing trend and territorial expansion to the Central and Eastern regions of the State. The results of this study indicated the increase in the incidence and lethality, as well as the expansion of leishmaniasis in Ceara State.

Increased detection of rabies virus in bats in Ceará State (Northeast Brazil) after implementation of a passive surveillance programme.

The intensification of dog, cat and livestock vaccination campaigns significantly reduced rabies cases in humans and domestic animals in Ceará State, Brazil. However, sylvatic animals-bats (order Chiroptera), wild canids, raccoons and non-human primates- remain as reservoirs for the virus. Our hypothesis is that surveillance and monitoring of rabies virus in bats, especially passive surveillance, is of fundamental importance, besides the implementation of health education and strengthening of surveillance actions in humans exposed to aggressions. Thus, we assessed the occurrence of rabies virus in animals focusing on bats, before and after launching of the Sylvatic Rabies Surveillance Program in 2010. Surveillance data from the 184 municipalities of Ceará State were analysed, collected during the periods 2003-2010 (active surveillance) and 2011-2016 (passive surveillance), respectively. A total of 13,543 mammalian samples were received for rabies diagnosis from 2003 to 2016. Of these, 10,960 were from dogs or cats (80.9%), 1,180 from bats (8.7%), 806 from other sylvatic animals (foxes, marmosets, raccoons; 6.0%) and 597 from herbivores (cattle, goats, sheep, equines, pigs; 4.4%). A total of 588 (4.3%) samples were positive for rabies. About 8.4% (99/1,180) of the bat samples were infected with rabies virus, 92 (92.9%) of these were from non-haematophagous bat species and 7 (7.1%) from haematophagous species. The number of bat samples received and infection rates increased considerably, after a shift from active surveillance (9/355 [2.5%] samples positive), to passive surveillance (90/825 [10.9%] samples positive). Surveillance of rabies virus in bats is fundamental for human and domestic animal health in Ceará State. Bats have to be considered as targets in surveillance and control programmes. Virus lineages should be characterized to increase knowledge on transmission dynamics of sylvatic rabies virus to domestic animals and the human population, and to provide additional evidence for planning and implementation of improved control measures.

Post-exposure human rabies prophylaxis: spatial patterns of inadequate procedures in Ceará - Brazil, 2007 to 2015

Abstract INTRODUCTION: This study investigated the spatial distribution of inappropriate post-exposure human rabies procedures in Ceará, Brazil, between 2007 and 2015. METHODS: The ecological study population was based on the records of post-exposure human rabies procedures from the Notification Disease Information System. We analyzed the data using the Moran Index (I) and the Moran Local Index. RESULTS: There were 222,036 (95.8%) records with inappropriate post-exposure human rabies procedures. There was heterogeneity in their spatial distribution, with two significant clusters in the northeast and northwest regions. CONCLUSIONS: These findings help elaborate differentiated strategies to reduce unnecessary post-exposure human rabies procedures.

Atendimentos antirrábicos humanos pós-exposição: tendência temporal de sua prevalência no Ceará, de 2007 a 2015 / Post-exposure human anti-rabies care: temporal trend of its prevalence in Ceará, from 2007 to 2015

Resumo Introdução A principal recomendação para o controle da raiva em humanos é a vacinação profilática. Objetivo Considerando-se a endemicidade da raiva no Brasil e o direcionamento das ações de controle, buscou-se caracterizar a tendência temporal dos atendimentos antirrábicos humanos pós-exposição no Ceará, de 2007 a 2015. Método O estudo é ecológico de tendência temporal e analítico. Os dados das fichas de atendimento antirrábico foram organizados em planilhas e calculados os coeficientes anuais de prevalência. Resultados Houve 231.694 atendimentos antirrábicos, com coeficientes de prevalência crescentes de 2007 a 2011 (35,09 por 10.000 habitantes; APC=13,5; p<0,001) e ápice em 2015 (40,35 por 10.000 habitantes; APC=5,5; p=0,005). Houve um aumento na faixa etária de 20 a 59 anos (APC=14,0; p<0,001), e residentes da zona urbana (APC=7,0; p<0,001). A espécie canina teve tendência crescente de 2007 a 2011 (APC=14,3; p<0,001). Das notificações, 95,8% apresentaram condutas inadequadas, com crescimento nos coeficientes de prevalência de 2007 a 2011 (APC=13,6; p<0,001). Conclusão As condutas profiláticas inadequadas aconteceram mais de 2007 a 2011. A análise temporal, com tendência crescente no período analisado, deve ser utilizada como componente contínuo das ações de vigilância da raiva no Ceará, para assistência adequada e segura aos pacientes vítimas de agressão animal.

Abstract Background The main recommendation for the control of rabies in humans is the prophylactic vaccination. Objective Considering the endemicity of rabies in Brazil and the direction of control actions, it was aimed to characterize the temporal trend of post-exposure human anti-rabies in Ceará from 2007 to 2015. Method The study is ecological with a temporal trend and analytical. The data of the anti-rabies data sheets were organized into spreadsheets and the annual prevalence coefficients were calculated. Results There were 231,694 rabies treatments, with prevalence coefficients increasing from 2007 to 2011 (35.09 per 10,000 inhabitants, APC = 13.5, p <0.001) and apex in 2015 (40.35 per 10,000 inhabitants, APC = 5, 5, p = 0.005). There was an increase in the age group of 20 to 59 years old (APC = 14.0, p <0.001), and urban residents (APC = 7.0, p <0.001). The canine species showed an increasing trend from 2007 to 2011 (APC = 14.3, p <0.001). Of the notifications, 95.8% presented inadequate behaviors, with an increase in the prevalence coefficients from 2007 to 2011 (APC = 13.6, p <0.001). Conclusion Inadequate prophylactic behaviors occurred more than 2007 to 2011. The temporal analysis, with an increasing trend in the analyzed period, should be used as a continuous component of the rabies surveillance actions in Ceará, for adequate and safe assistance to the patients who are victims of animal aggression.

Human rabies: evaluation of post-exposure prophylaxis prevalence in Ceará, Brazil, 2007-2015. / Raiva humana: avaliação da prevalência das condutas profiláticas pós-exposição no Ceará, Brasil, 2007-2015.

OBJECTIVE: to analyze the prevalence of inadequate human anti-rabies post-exposure prophylaxis in patients attacked by animals in the state of Ceará, Brazil, 2007-2015. METHODS: this was a study of the prevalence of inadequate prophylaxis procedures, using data on reported cases of accidents involving animals potentially capable of transmitting rabies registered on the Notifiable Diseases Information System (SINAN) from January 2007 to December 2015. RESULTS: of the 231,694 reported cases, 95.8% were found to have inadequate procedures, especially in young people aged under 19 (37.6%), with no difference between the sexes (p=0.04); higher prevalence rate of inadequate procedures occurred with regard to exposure to bites (PR=1.03 - 95%CI 1.02;1.03), multiple injuries (PR=1.07 - 95%CI 1.06;1.07), accidents involving dead/missing animals (RP=1.05 - 95%CI 1.05;1.06), and vaccine treatments (RP=1.03 - 95%CI 1.02;1.03). CONCLUSION: high prevalence of inadequate procedures indicates the need for a better epidemiological evaluation of cases and compliance with the Human Rabies Prophylaxis Technical Standards, in order to ensure adequate anti-rabies prophylaxis procedures.

Objetivo: analisar a prevalência da profilaxia antirrábica humana pós-exposição inadequada em pacientes vítimas de agressão por animal no Ceará, Brasil, 2007 a 2015. Métodos: estudo de prevalência de condutas profiláticas inadequadas, com dados das notificações dos acidentes por animais potencialmente transmissores da raiva registrados no Sistema de Informação de Agravos de Notificação (Sinan), de janeiro de 2007 a dezembro de 2015. Resultados: de 231.694 notificações, 95,8% apresentaram inadequações, principalmente em menores de 19 anos (37,6%), sem diferença entre os sexos (p=0,04); maiores prevalências de condutas inadequadas aconteceram na exposição por mordedura (RP=1,03 - IC95% 1,02;1,03), nos ferimentos múltiplos (RP=1,07 - IC95% 1,06;1,07), nos acidentes com animais mortos/desaparecidos (RP=1,05 - IC95% 1,05;1,06) e nos tratamentos com vacinas (RP=1,03 - IC95% 1,02;1,03). Conclusão: a alta prevalência de condutas inadequadas aponta a necessidade de melhor avaliação epidemiológica dos casos e o atendimento às Normas Técnicas de Profilaxia da Raiva Humana, para a condução adequada da profilaxia antirrábica.
