Prevalence of trachoma in the non-indigenous Baixo Jaguaribe micro-region, Ceará State, Northeast Brazil.

BACKGROUND: The aim of the current study was to estimate the population prevalence of trachoma in non-indigenous populations in the Baixo Jaguaribe micro-region, in the state of Ceará, northeast region of Brazil, 2021-2022. METHODS: A population-based prevalence survey focusing on detecting cases of trachomatous inflammation-follicular (TF) in children aged 1-9 y and trachomatous trichiasis (TT) 'unknown to the health system' in people aged ≥15 y, was conducted in rural areas of the Baixo Jaguaribe micro-region in the state of Ceará. Indigenous populations will be further researched. RESULTS: There was no detection of cases of TF and TT. In 900 households, 2234 people were examined. In the Baixo Jaguaribe micro-region, females (54.6%; 1219/2234) and the mixed/Pardo-Brazilian ethnicity (68.1%; 1521/2234) predominated. The most commonly reported educational level was elementary and middle school (41.8%; 702/1679). In 56.2% (506/900) of households, there was a source of water within the household. The monthly income range of 50%-100% of the minimum wage predominated in the families of the Baixo Jaguaribe micro-region (43.1%; 388/900). CONCLUSIONS: Although no cases of TF and TT were detected in the Baixo Jaguaribe micro-region in the state of Ceará during the study period, considering the historical endemicity, we emphasise the need for monitoring and sustainability of surveillance actions in areas at risk for trachoma, common contexts for neglected populations.

Scientometric analysis of research on trachoma in Brazil, 2000-2020.

OBJECTIVE: To analyze the scientometric profile of research on trachoma in Brazil. METHODS: Bibliographic research of publications on trachoma in Brazil indexed by the Scopus database from 2000 to 2020, based on specific criteria. Data on authorship, country of origin, institutions, and keywords were collected and analyzed with analysis of time trends. Bibliographic networks were constructed via a scientometric visualization software-VOSviewer® 1.6.16. RESULTS: We analyzed 42 publications on trachoma in Brazil. The annual average was two articles, with an increase of about 50% during the period. The average number of authors was three per document and school surveys were the most common subject category. Most published articles came from Brazilian institutions (95.2%), mainly those based in Southeast and North Brazil. Of the most productive authors, 10 were mentioned as first author in 26.2% of publications (11/42) and the predominant institutions are based in the state of São Paulo. The term "trachoma" (n = 18) was the most recurrent keyword. CONCLUSION: This first scientometric analysis of research on trachoma in Brazil showed a limited number of studies on this disease. The scientific production slightly increased, although the origin of many studies is geographical areas with lower endemicity of this disease. Greater investments are needed for a better understanding and control of this neglected tropical disease. The analysis of bibliographic production on this topic is important to strengthen the development of research and strategic planning of programs for the control of trachoma and neglected tropical diseases in general.

Territory, neglected diseases and the action of community and endemic combat agents.

OBJECTIVE: To characterize knowledge, practices, and professional experience of community health agents (ACS) and endemic combat agents (ACE) on leprosy and Chagas disease (DC), during participation in an integrated training workshop in the IntegraDTNs-Bahia project. METHODS: Descriptive and exploratory case study, involving health agents and endemic combat agents participating in a training workshop on the shared role of these professionals in health care and surveillance processes. The project was developed in the municipalities of Anagé, Tremedal and Vitória da Conquista, in the southwestern State of Bahia, 2019-2020. A specific instrument was applied, with questions related to knowledge and practices of surveillance and care for leprosy and Chagas disease. Descriptive analysis of the data, in addition to consolidation of the lexical analysis, was performed. RESULTS: Out of a total of 135 participants (107 ACS and 28 ACE), 80.7% of them have been working for at least 12 years, without previous participation in joint training processes. Only 17.9% of endemic combat agentes reported having participated in training on leprosy and none reported developing specific actions to control the disease. For Chagas disease, 36.4% of community health agents participated in training more than a decade before, while for 60.7% of endemic combat agents the last training was carried out in the last five years. The development of educational actions for Chagas disease was more frequent for endemic combat agents (64.3%). When asked about ways of recognizing diseases, the term "skin spots" was the most reported (38 times) for leprosy and, for Chagas disease, the term "I don't know" (17 times). CONCLUSION: Processes of health agents and endemic combat agents action in realities endemic for leprosy and Chagas disease in the interior of Bahia proved to be fragmented in the territories. For these diseases, the distance between surveillance and health care actions is reinforced, including in training processes. The importance of innovative permanent and integrated education actions is reiterated to actually promote changes in practices.

Socio-demographic and clinical factors of leprosy cases associated with the performance of the evaluation of their contacts in Ceará, Brazil, 2008-2019. / Fatores sociodemográficos e clínicos de casos de hanseníase associados ao desempenho da avaliação de seus contatos no Ceará, 2008-2019.

OBJECTIVE: To analyze the effect of sociodemographic and clinical characteristics of new leprosy cases as determinants in the performance of the evaluation of their contacts. METHODS: This was a cross-sectional study, with a temporal approach to the evaluation indicator of 100% of contacts examined of each new case (NC) registered in the state of Ceará, Brazil, on the Notifiable Diseases Information System (SINAN), in 2008-2019. Logistic regression was used to estimate odds ratio (OR) with 95% confidence intervals (95%CI). The temporal trends were analyzed using joinpoint regression. RESULTS: 23,675 NCs, 65.4% with contacts examined were analyzed. It was less likely to evaluate 100% of the registered contacts when the new cases were multibacillary (OR=1.19 - 95%CI 1.11;1.28) and with examination of contacts as an entry mode (OR=1.71 - 95%CI 1.35;2.18). There was an increasing temporal trend of the indicator (Annual Percentage Change: 2.1 - 95%CI 1.2;3.0). CONCLUSION: Distinct dimensions of individual and social vulnerability among new leprosy cases influenced the persistent unsatisfactory performance of the evaluation of contacts.

Seroprevalence and risk factors of Chagas disease in a rural population of the Quixeré municipality, Ceará, Brazil.

INTRODUCTION: This study estimated the seroprevalence and risk factors of Chagas disease (CD) in a population of the Quixeré municipality, Ceará. METHODS: We conducted serological methods to detect the Trypanosoma cruzi infection. The other variables were evaluated by a standardized questionnaire. RESULTS: The estimated prevalence of CD was 3.7%. Male sex, age >40 years, being farmers, low education level, origin from rural areas, and being born in Quixeré were significantly associated with infection. CONCLUSION: CD persists in this rural population of Northeast Brazil. Poverty, low education, and limited information regarding CD are critical issues that need to be addressed.

Operational failures of leprosy control in household social networks with overlapping cases in endemic areas in Brazil. / Falhas operacionais no controle da hanseníase em redes de convívio domiciliar com sobreposição de casos em áreas endêmicas no Brasil.

OBJECTIVE: To analyze institutional/programmatic vulnerability of health services in the development of health care actions for people affected by leprosy and contact surveillance. METHODS: This was a cross-sectional study conducted in 2017 based on primary data from a sample of leprosy cases notified between 2001-2014 with overlapping cases in household social networks (HSN) in municipalities in the states of Bahia, Piauí and Rondônia, Brazil. RESULTS: A total of 233 leprosy cases were analyzed, 154 (66.1%) belonged to HSN with 3 or more leprosy cases. In 53.2% of cases, 2 or more generations were affected, this being an outcome associated with absence of dermato-neurological examination (prevalence ratio 1.32; confidence interval [95%CI 1.10;1.59]; p-value=0.004). CONCLUSION: Operational failures in the surveillance of leprosy contacts in areas of high endemicity reinforce the character of institutional/programmatic vulnerability in HSN contexts with more than one case of leprosy in the three states analyzed.

Characterization of tinnitus in the elderly and its possible related disorders.

UNLABELLED: Population aging it is a current reality in Brazil and tinnitus appears as a very prevalent symptom, having a high impact on the quality of life of elderly patients. AIM: To evaluate and to characterize tinnitus in this group. MATERIALS AND METHODS: A research questionnaire randomly given to 100 elderly patients in a tertiary hospital, asking about tinnitus characteristics, its impact on the life of the patient, and personal medical history. RESULTS: 61% of the participants were female, average age average was 69.53 years. The results associated with tinnitus features were: no-pulsatile 76%, continuous 54%, bilateral 57%, recent 62% and alone 83%;32,5% had emotional disorders, 31.8% had sleep disorders, 22.5% had difficulties concentration and 13.2% had social problems; 39% classified their tinnitus in moderate; 35% had intense tinnitus and 26% considered it a mild one: as to comorbidities: relation with neurotology symptoms and hypertension; as for associations with audiometry findings: descending, sensorineural and symmetrical curves prevailed. CONCLUSIONS: Tinnitus has a relevant impact on the lives of the elderly; there was no correlation between the level of hearing loss and the level of patient dissatisfaction caused by tinnitus; and presbycusis was the most common finding in the audiometric tests.

Nutritional aspects of people affected by leprosy, between 2001 and 2014, in semi-arid Brazilian municipalities. / Aspectos nutricionais de pessoas acometidas por hanseníase, entre 2001 e 2014, em municípios do semiárido brasileiro.

The study aimed to characterize food insecurity, nutritional status, and eating habits of people affected by leprosy. This is a descriptive cross-sectional study based on a census population. We evaluated 276 cases, reported in the Notifiable Diseases Information System, between 2001 and 2014, in the municipalities of Vitória da Conquista and Tremedal, in the state of Bahia. Food insecurity was estimated according to the Brazilian Food Insecurity Scale. We collected weight and height measurements, meal frequency, and household, socioeconomic, psychosocial and clinical variables. The prevalence of food insecurity was 41.0% among the study population - 28.3% mild, 8.0% moderate and 4.7% severe. Overweight/obesity was estimated in 60.1% of the study participants, and excessive salt intake was reported by 8.6%. Beans and red meat were the most regularly consumed foods; there was low consumption of milk, raw and cooked vegetables, and fruits. This population presented high food insecurity prevalence, inadequate eating habits and nutritional status, reflecting nutritional vulnerability. The insertion of nutritional assistance in the leprosy control programmes is recommended, to improve health care.

O estudo buscou caracterizar a insegurança alimentar, o estado nutricional e os hábitos alimentares de pessoas acometidas por hanseníase. Trata-se de um estudo transversal descritivo, de população censitária, em que foram avaliados 276 casos, notificados no Sistema de Informação de Agravos de Notificação, entre 2001 e 2014, nos municípios de Vitória da Conquista e Tremedal, Bahia. Na análise foi empregada a Escala Brasileira de Insegurança Alimentar. Foram coletadas medidas de peso e altura, frequência alimentar, variáveis domiciliares, socioeconômicas, psicossociais e clínicas. A prevalência de insegurança alimentar foi de 41,0% na população; sendo 28,3% leve, 8,0% moderada e 4,7% grave. O sobrepeso/obesidade foi estimado em 60,1% das pessoas avaliadas e o consumo excessivo de sal foi relatado por 8,6%. O feijão e a carne vermelha foram os alimentos mais regularmente consumidos e houve baixo consumo de leite, hortaliças cruas e cozidas e frutas. A insegurança alimentar apresentou elevada prevalência, associada à inadequação do hábito alimentar e estado nutricional, refletindo a vulnerabilidade nutricional desta população. Recomenda-se a inserção da assistência nutricional às políticas públicas da hanseníase, como forma de qualificar a atenção à saúde.

Surveillance of intradomiciliary contacts of leprosy cases: perspective of the client in a hyperendemic municipality.

OBJECTIVE: To characterize approach methods for intradomiciliary contacts (IdC) of leprosy cases resident in Northern Brazil, during 2001-2012. METHOD: A cross-sectional and descriptive study in the state of Rondônia. Included IdC of leprosy cases diagnosed/reported in SINAN-Ministry of Health (MS), 2001-2012. A semi-structured instrument was applied to the IdCs, with six interventions: complete dermatological examination; complete neurological examination; BCG vaccination; instructions for return to the health unit; BCG guidance; and guidance to mobilize other contacts.Results: From a total of 459 IdCs included, failure to perform the dermatological examination was reported by 191 people (41.6%) and the neurological examination, by 252 (54.9%); 138 (30.1%) did not have BCG indicated and 122 (26.6%) did not receive guidelines; 257 (56.0%) were not advised to return for a new evaluation/follow-up and 186 (40.5%) were not asked to mobilize other contacts. CONCLUSION: Despite the favorable indicators of IdC examination coverage in the state, the evaluation process presents patterns that indicate operational quality failures.

Is Visceral Leishmaniasis the same in HIV-coinfected adults?

INTRODUCTION: Visceral Leishmaniasis is the most severe form of disease caused by the Leishmania donovani complex, with significant morbidity and mortality in developing countries. Worse outcomes occur among HIV-positive individuals coinfected with Leishmania. It is unclear, however, if there are significant differences on presentation between Visceral Leishmaniasis patients with or without HIV coinfection. METHODS: We reviewed medical records from adult patients with Visceral Leishmaniasis treated at a reference healthcare center in Fortaleza - Ceará, Brazil, from July 2010 to December 2013. Data from HIV-coinfected patients have been abstracted and compared to non-HIV controls diagnosed with Visceral Leishmaniasis in the same period. RESULTS: Eighty one HIV-infected patients and 365 controls were enrolled. The diagnosis in HIV patients took significantly longer, with higher recurrence and death rates. Kala-azar's classical triad (fever, constitutional symptoms and splenomegaly) was less frequently observed in Visceral Leishmaniasis-HIV patients, as well as jaundice and edema, while diarrhea was more frequent. Laboratory features included lower levels of hemoglobin, lymphocyte counts and liver enzymes, as well as higher counts of blood platelets and eosinophils. HIV-infected patients were diagnosed mainly through amastigote detection on bone marrow aspirates and treated more often with amphotericin B formulations, whereas in controls, rK39 was the main diagnostic tool and pentavalent antimony was primarily used for treatment. CONCLUSIONS: Clinical and laboratory presentation of Visceral Leishmaniasis in HIV-coinfected patients may differ from classic kala-azar, and these differences may be, in part, responsible for the delay in diagnosing and treating leishmaniasis, which might lead to worse outcomes.

Identification of Biomphalaria sp. and other freshwater snails in the large-scale water transposition project in the Northeast of Brazil.

The wide eco-bio-social intervention generated by the SaoFrancisco River Integration Project (PISF) may contribute to the dispersion or introduction of schistosomiasis intermediate hosts in areas without prior recording. The objective was to characterize the limnic malacofauna and its distribution along watersheds involved in the PISF. A cross-sectional study based on the collection of mollusks from 33 water bodies, from Aurora, Brejo Santo, Jaguaretama, Jaguaribara, Jati e Mauriti municipalities in the Ceara (CE) State was developed. The conchological characteristics were used to identify snails at the genus level. The snails of the genus Biomphalaria were analyzed for the presence of Schistosoma mansoni cercariae and the molecular identification (only mollusks from Brejo Santo-CE) for differentiation between species. The following species were found: Biomphalaria sp.; Drepanotrema sp.; Melanoides sp.; Physa sp.; and Pomacea sp. Pomacea sp. (75.8%) and Biomphalaria sp. (72.7%) were the most prevalent species. All municipalities showed Biomphalaria sp. Biomphalaria straminea (Porcos Stream) and Biomphalaria kuhniana was identified in the Boi 1 and Cipo reservoirs (Brejo Santo). The evaluated municipalities under the influence of the PISF present areas with potential for schistosomiasis transmission. It is necessary to intensify control actions and health surveillance in these areas.

Scientometric analysis of research on trachoma in Brazil, 2000-2020 / Análise cienciométrica da pesquisa sobre tracoma no Brasil, 2000-2020

Foram extraídos e analisados dados sobre autoria, país de origem, instituições e descritores, com análises de tendências temporais. As redes bibliográficas foram construídas via software de visualização cienciométrica VOSviewer® 1.6.16. RESULTADOS Do total de 42 publicações analisadas sobre tracoma no Brasil, observou-se média anual de dois artigos, com incremento de aproximadamente 50% no período. Verificou-se média de três autores por documento e os inquéritos escolares foram a categoria de assunto mais comum. Os artigos publicados provêm majoritariamente de instituições brasileiras (95,2%), principalmente das sediadas nas regiões Sudeste e Norte. Dez autores mais produtivos estão mencionados nas primeiras autorias em 26,2% (11/42) das publicações e as instituições predominantes estão afiliadas ao estado de São Paulo. O termo Trachoma (n = 18) apresenta maior recorrência como descritor. CONCLUSÃO Esta primeira análise cienciométrica sobre tracoma no Brasil evidencia limitado número de pesquisas sobre essa doença. Há discreto incremento da produção científica, apesar da concentração da origem em áreas geográficas com menor endemicidade da doença. Maiores investimentos são necessários para o melhor entendimento e controle dessa doença tropical negligenciada. A análise da produção bibliográfica tem papel relevante para fortalecimento do desenvolvimento de pesquisas e planejamento estratégico de programas para o controle de tracoma e doenças tropicais negligenciadas em geral.

Territory, neglected diseases and the action of community and endemic combat agents / Território, doenças negligenciadas e ação de agentes comunitários e de combate a endemias

ABSTRACT OBJECTIVE To characterize knowledge, practices, and professional experience of community health agents (ACS) and endemic combat agents (ACE) on leprosy and Chagas disease (DC), during participation in an integrated training workshop in the IntegraDTNs-Bahia project. METHODS Descriptive and exploratory case study, involving health agents and endemic combat agents participating in a training workshop on the shared role of these professionals in health care and surveillance processes.

RESUMO OBJETIVO Caracterizar conhecimentos, práticas e experiência profissional de agentes comunitários de saúde (ACS) e agentes de controle de endemias (ACE) sobre hanseníase e doença de Chagas (DC), durante participação em oficina de formação integrada no projeto IntegraDTNs-Bahia. MÉTODOS Estudo de caso descritivo e exploratório, envolvendo comunitários de saúde e agentes de controle de endemias, participantes de oficina de formação sobre o papel compartilhado desses profissionais no processo de vigilância e atenção à saúde. Projeto desenvolvido nos municípios de Anagé, Tremedal e Vitória da Conquista, no Sudoeste do Estado da Bahia, 2019-2020. Aplicou-se instrumento específico prévio com questões relativas a conhecimentos e práticas de vigilância e atenção para hanseníase e doença de Chagas. Análise descritiva dos dados, além de consolidação da análise léxica. RESULTADOS Do total de 135 participantes (107 ACS e 28 ACE), 80,7% deles atuam há pelo menos 12 anos, sem participação prévia em processos de formação conjunta. Apenas 17,9% dos agentes de controle de endemias relataram ter participado de capacitações sobre hanseníase e nenhum informou desenvolver ações específicas de controle da doença. Para a doença de Chagas, 36,4% dos agentes comunitários de saúde participaram de capacitações há mais de uma década, enquanto para 60,7% dos agentes de controle de endemias a última capacitação foi realizada nos últimos cinco anos. O desenvolvimento de ações educativas para a doença de Chagas foi mais frequente para agentes de controle de endemias (64,3%). Quando perguntados sobre formas de reconhecimento das doenças, a palavra "manchas na pele" foi a mais relatada (38 vezes) para hanseníase e, para a doença de Chagas, a palavra "não sei" (17 vezes). CONCLUSÃO Os processos de atuação de agentes comunitários de saúde e agentes de controle de endemias em realidades endêmicas para hanseníase e doença de Chagas no interior da Bahia revelaram-se desintegrados nos territórios. Para essas doenças, reforça-se o distanciamento entre ações de vigilância e de atenção à saúde, inclusive nos processos de capacitação. Reitera-se a importância de ações inovadoras de educação permanentes e integradas para promover de fato mudanças nas práticas.

[Aedes aegypti resistance to temefos in counties of Ceará State]. / Resistência do Aedes aegypti ao temefós em Municípios do Estado do Ceará.

The susceptibility of Aedes aegypti to temefos was evaluated by means of samples of eggs and larvae from four large counties in the state of Ceará (Fortaleza, Barbalha, Juazeiro do Norte and Crato). The technique standardized by the World Health Organization for tests with larvicides was used. The CL50 of eight samples from populations of Aedes was determined, as were their respective resistance ratios, compared to the CL50 of the susceptible Rockefeller strain. All populations submitted to the experiment showed resistance to temefos, with resistance ratios varying between 8 and 16. Analysis of these results reinforces prior evidence regarding the dissemination of temefos resistance in different locations in the state, subjected to considerable pressure for control in recent decades. The larvicide may lose its effectiveness if an urgent attempt is not made to reestablish the susceptibility of Aedes aegypti in these areas, profoundly affecting control campaigns currently under way.

Temporal trends of leprosy in a Brazilian state capital in Northeast Brazil: epidemiology and analysis by joinpoints, 2001 to 2012. / Tendência temporal da hanseníase em uma capital do Nordeste do Brasil: epidemiologia e análise por pontos de inflexão, 2001 a 2012.

The objective of this study was to characterize epidemiological and temporal trends of leprosy in the city of Fortaleza, Ceará, Brazil, from 2001 to 2012. A total of 9,658 new cases were reported. Their temporal trend was analyzed by the jointpoint regression model. The overall detection rate showed a declining trend, with annual percent change (APC) of -4.0 and 95% confidence interval (95%CI) -5.6 - -2.3. The detection rate in children under 15 years of age (APC = -1.4; 95%CI -5.4 - 2.8) and the detection rate of disability grade 2 (APC = -0.8; 95%CI -4.5 - 3.1) were stable. The proportion of female patients was descending (APC = -1,5; 95%CI -2.3 - -0.8). The proportion of multibacillary cases from 2005 to 2012 (APC = 1.4; 95%CI 0.6 - 2.3) and among them, lepromatous cases from 2004 to 2012 (APC = 6.0; 95%CI 3.4 - 8.6) were increasing. There was stability in the proportion of cases with grade 1 (APC = 1.4; 95%CI -0.9 - 3.7) and grade 2 disability (APC = 3.7; 95%CI -0.1 - 7.8). Despite the trend towards a reduction in detection, the disease transmission persists in the city. The data also suggest late diagnosis.

Fatores sociodemográficos e clínicos de casos de hanseníase associados ao desempenho da avaliação de seus contatos no Ceará, 2008-2019 / Factores sociodemográficos y clínicos de los casos de lepra asociados con el desempeño de la evaluación de sus contactos en Ceará, Brasil, 2008-2019 / Socio-demographic and clinical factors of leprosy cases associated with the performance of the evaluation of their contacts in Ceará, Brazil, 2008-2019

Objetivo:Analisar o efeito de características sociodemográficas e clínicas de casos novos (CNs) de hanseníase como determinantes no desempenho da avaliação dos contatos. Métodos: Estudo transversal, com abordagem temporal do indicador de avaliação de 100% os contatos examinados de CNs registrados no Ceará, Brasil, via Sistema de Informação de Agravos de Notificação (Sinan), em 2008-2019. Empregou-se regressão logística para estimar razão de chances-odds ratio (OR) com intervalos de confiança de 95% (IC95%). A tendência temporal baseou-se em regressão joinpoint. Resultados: Foram analisados 23.675 CNs, 65,4% com contatos examinados. Verificou-se maior chance para não avaliação de 100% dos contatos registrados com CN multibacilar (OR=1,19 - IC95% 1,11;1,28) e com exame de contatos como modo de entrada (OR=1,71 - IC95% 1,35;2,18). A tendência temporal do indicador foi de aumento (variação percentual anual: 2,1 - IC95% 1,2;3,0). Conclusão: Dimensões distintas de vulnerabilidade individual e social de CNs de hanseníase influenciam o persistente desempenho insatisfatório da avaliação de contatos.

Seroprevalence and risk factors of Chagas disease in a rural population of the Quixeré municipality, Ceará, Brazil

Abstract INTRODUCTION: This study estimated the seroprevalence and risk factors of Chagas disease (CD) in a population of the Quixeré municipality, Ceará. METHODS: We conducted serological methods to detect the Trypanosoma cruzi infection. The other variables were evaluated by a standardized questionnaire. RESULTS: The estimated prevalence of CD was 3.7%. Male sex, age >40 years, being farmers, low education level, origin from rural areas, and being born in Quixeré were significantly associated with infection. CONCLUSION: CD persists in this rural population of Northeast Brazil. Poverty, low education, and limited information regarding CD are critical issues that need to be addressed.

Yellow fever risk assessment in the Central African Republic.

Yellow fever still causes high burden in several areas of sub-Saharan Africa and Latin America. There are few well-designed epidemiological studies and limited data about yellow fever in Africa. Staples et al., in a recently published paper in Transactions of the Royal Society of Tropical Medicine & Hygiene, performed a nationwide study in the Central African Republic (CAR) assessing infection risk and the operational impact of preventive measures. The rapid assessment of human, non-human and mosquito data call attention to the potential risk of future yellow fever outbreaks in the CAR and elsewhere. The study reinforces the need for intensified applied and operational research to address problems and human capacity needs in the realm of neglected tropical diseases in the post-2015 agenda.
