IntroductionSchistosomiasis (SCH) and soil transmitted helminthiases (STH) have been historically recognized as a major public health problem in Angola. However, lack of reliable, country wide prevalence data on these diseases has been a major hurdle to plan and implement programme actions to target these diseases. This study aimed to characterize SCH and STH prevalence and distribution in Angola.MethodsA country wide mapping was conducted in October 2018 (1 province) and from July to December 2019 (14 provinces) in school aged (SAC) children in 15 (of 18) provinces in Angola, using WHO protocols and procedures. A total of 640 schools and an average of 50 students per school (N = 31,938 children) were sampled. Stool and urine samples were collected and processed using the Kato-Katz method and Urine Filtration. Prevalence estimates for SCH and STH infections were calculated for each province and district with 95% confidence intervals. Factors associated with SCH and STH infection, respectively, were explored using multivariable logistic regression accounting for clustering by school.ResultsOf the 131 districts surveyed, 112 (85.5%) are endemic for STH, 30 (22.9%) have a prevalence above 50%, 24 (18.3%) are at moderate risk (prevalence 20%-50%), and 58 (44.3%) are at low risk (50% prevalence), 59 (45.0%) are at moderate risk (10%-50% prevalence), and 57 (43.5%) are at low risk (ConclusionsThis mapping exercise provides essential information to Ministry of Health in Angola to accurately plan and implement SCH and STH control activities in the upcoming years. Data also provides a useful baseline contribution for Angola to track its progress towards the 2030 NTD roadmap targets set by WHO.

Background This last decade's ongoing conflict in the Central African Republic (CAR) has led to gradual and continuous destruction of health services. With severe gaps in qualified health professionals, community health workers (CHWs) have become essential to ensuring health care access to the affected population. This article aims to evaluate the effectiveness of a 10-y CHW program in the CAR. Methods Routine case management data from CHWs were collected in the Paoua district from January 2012 to December 2017 and analysed. Structured interviews were conducted in the Paoua and Carnot health districts among individuals from three different groups (health service beneficiaries, CHWs and health facility managers). Results From 2012 to 2017, 353 948 people consulted for malaria suspicion with CHWs and 86% were found to be malaria positive after a rapid diagnostic test. Among those diagnosed patients, 98.5% received adequate treatment and nearly 1.5% were referred to health facilities. Also, 94.5% of respondents identified fever as the major malaria symptom. About 70% of the population could identify three malaria signs/symptoms and 84.4% accepted and used CHW services. Interviews with CHWs revealed that 45.8% of them received at least four training sessions per month as part of their capacity building. Conclusions CHWs can be a resourceful solution when other health professional are scarce. This study showed that CHWs are not only able to deliver curative and preventive health services, but they are also well accepted by the served communities. [ABSTRACT FROM AUTHOR]
