Background: The human helminth infections include ascariasis, trichuriasis, hookworm infections, schistosomiasis, lymphatic filariasis (LF) and onchocerciasis. It is estimated that almost 2 billion people worldwide are infected with helminths. Whilst the WHO treatment guidelines for helminth infecti...ons are mostly aimed at controlling morbidity, there has been a recent shift with some countries moving towards goals of disease elimination through mass drug administration, especially for LF and onchocerciasis. However, as prevalence is driven lower, treating entire populations may no longer be the most efficient or cost-effective strategy. Instead, it may be beneficial to identify individuals or demographic groups who are persistently infected, often termed as being “predisposed” to infection, and target treatment at them.
Methods: The authors searched Embase, MEDLINE, Global Health, and Web of Science for all English language, humanbased papers investigating predisposition to helminth infections published up to October 31st, 2017. The varying definitions used to describe predisposition, and the statistical tests used to determine its presence, are summarised. Evidence for predisposition is presented, stratified by helminth species, and risk factors for predisposition to infection are identified and discussed.
Results: In total, 43 papers were identified, summarising results from 34 different studies in 23 countries. Consistent evidence of predisposition to infection with certain species of human helminth was identified. Children were regularly found to experience greater predisposition to Ascaris lumbricoides, Schistosoma mansoni and S. haematobium than adults. Females were found to be more predisposed to A. lumbricoides infection than were males. Household clustering of infection was identified for A. lumbricoides, T. trichiura and S. japonicum. Ascaris lumbricoides and T. trichiura also showed evidence of familial predisposition. Whilst strong evidence for predisposition to hookworm infection was identified, findings with regards to which groups were affected were considerably more varied than for other helminth species.
Conclusion: This review has found consistent evidence of predisposition to heavy (and light) infection for certain human helminth species. However, further research is needed to identify reasons for the reported differences between demographic groups. Molecular epidemiological methods associated with whole genome sequencing to determine ‘who infects whom’ may shed more light on the factors generating predisposition.

Policy brief. HIV testing services (HTS) and anti-retroviral therapy (ART) have been scaled up substantially. It is estimated that, globally, nearly 80% of people with HIV now know their status. With the offer of immediate ART initiation and improved treatment options, access to and uptake of treatm...ent have increased, too. Now, most people with HIV who know their status are obtaining treatment and care.
In response to these changes in the global HIV epidemic, WHO is encouraging countries to use three consecutive reactive tests for an HIV-positive diagnosis as their treatment-adjusted prevalence and national HTS positivity fall below 5% .

Insufficient funding is hindering the achievement of malaria elimination targets in Africa, despite the pressing need for increased investment in malaria control. While Western donors attribute their inaction to financial constraints, the global health community has limited knowledge of China’s ex...panding role in malaria prevention. This knowledge gap arises from the fact that China does not consistently report its foreign development assistance activities to established aid transparency initiatives. Our work focuses on identifying Chinese-funded malaria control projects throughout Africa and linking them to official data on malaria prevalence. By doing so, we aim to shed light on China’s contributions to malaria control efforts, analysing their investments and assessing their impact. This would provide valuable insights into the development of effective financing mechanisms for future malaria control in Africa.

Government spending on health from domestic sources is an important indicator of a government's commitment to the health of its people, and is essential for the sustainability of health programmes. We aimed to systematically analyse all data sources available for government spending on health in dev...eloping countries; describe trends in public financing of health; and test the extent to which they were related to changes in gross domestic product (GDP), government size, HIV prevalence, debt relief, and development assistance for health (DAH) to governmental and non-governmental sectors.

From 2000 to 2010, Rwanda implemented comprehensive health sector reforms to strengthen the public health system, with the aim of reducing maternal and newborn deaths in line with Millennium Development Goal 5, among many other improvements in national health. Based on a systematic review of the lit...erature, national policy documents and three Demographic & Health Surveys (2000, 2005 and 2010), this paper describes the reforms and the policies they were based on, and provides data on the extent of Rwanda’s progress in expanding the coverage of four key women’s health services. Progress took place in 2000–2005 and became more rapid after 2006, mostly in rural areas, when the national facility-based childbirth policy, performance-based financing, and community-based health insurance were scaled up. Between 2006 and 2010, the following increases in coverage took place as compared to 2000–2005, particularly in rural areas, where most poor women live: births with skilled attendance (77% increase vs. 26%), institutional delivery (146% increase vs. 8%), and contraceptive prevalence (351% increase vs. 150%). The primary factors in these improvements were increases in the health workforce and their skills, performance-based financing, community-based health insurance, and better leadership and governance. Further research is needed to determine the impact of these changes on health outcomes in women and children.

Cystic fibrosis (CF) was earlier thought to be a disease prevalent in the West among Caucasians. However, quite a number of recent studies have uncovered CF cases outside of this region, and reported hundreds of unique and novel variant forms of CFTR. Here, we discuss the evidence of CF in parts of... the world earlier considered to be rare; Africa, and Asia. This review also highlighted the CFTR mutation variations and new mutations discovered in these regions. This discovery implies that the CF data from these regions were earlier underestimated. The inadequate awareness of the disease in these regions might have contributed towards the poor diagnostic facilities, under-diagnosis or/and under-reporting, and the lack of CF associated health policies. Overall, these regions have a high rate of infant, childhood and early adulthood mortality due to CF. Therefore, there is a need for a thorough investigation of CF prevalence and to identify unique and novel variant mutations within these regions in order to formulate intervention plans, create awareness, develop mutation specific screening kits and therapies to keep CF mortality at bay.

L’enquête a été réalisée dans la Commune de Dori, chef-lieu de la province du Seno dans la Région du Sahel. Suite à la crise sécuritaire qui prévaut au Burkina Faso depuis 2016, la commune de Dori a enregistré 66 7981 personnes déplacées à la date du 30 Avril 2022. Ce chiffre est le p...lus élevé dans la province du Séno. Les déplacées ont été contraints d’abandonner leurs moyens d’existence, font face à la précarité, bénéficient de l’assistance gouvernementale, des acteurs humanitaires et des populations hôtes.
Il s’agit d’une SMART Rapide. Les secteurs/villages ont été sélectionnés par le logiciel ENA en utilisant la probabilité proportionnelle à la taille. Quant aux ménages, ils ont été sélectionnés selon un processus de segmentation et d’échantillonnage aléatoire simple ou systématique.
Les données ont été collectées du 13 au 15 Juin 2022 par 5 équipes composées d’un chef et d’un mesureur chacune. Les équipes ont été supervisées durant toute la collecte. Les paramètres collectés étaient l’âge, le sexe, le poids, la taille, le périmètre brachial et la présence des œdèmes. Trois grappes ont été inaccessibles due aux problèmes sécuritaires et les trois grappes de réserves prévues à cet effet ont été utilisées.
Au total 25 grappes, 245 ménages, et 246 enfants ont été enquêtés. Les résultats montrent une prévalence de la malnutrition aiguë globale de 19,8 % (IC 95 % ; 14,7 - 26,1) selon le rapport poids/taille) et 5,3 % (IC 95 % : 3,0 - 9,1) selon le périmètre brachial. La malnutrition aiguë globale combinée est de 22,4 % (IC 95 % : 17,3 - 28,5).

This document adopts a health determinants framework for examining the evidence related to women’s poor mental health. From this perspective, public policy including economic policy, socio-cultural and environmental factors, community and social support, stressors and life events, personal behavio...ur and skills, and availability and access to health services, are all seen to exercise a role in determining women’s mental health status. Similarly, when considering the differences between women and men, a gender approach has been used. While this does not exclude biological or sex differences, it considers the critical roles that social and cultural factors and unequal power relations between men and women play in promoting or impeding mental health. Such inequalities create, maintain and exacerbate exposure to risk factors that endanger women’s mental health, and are most graphically illustrated in the significantly different rates of depression between men and women, poverty and its impact, and the phenomenal prevalence of violence against women.

ajtmh.20-1538 Volume 104, 6. Mapping is a prerequisite for effective implementation of interventions against neglected tropical diseases (NTDs). Before the accelerated World Health Organization (WHO)/Regional Office for Africa (AFRO) NTD Mapping Project was initiated in 2014, mapping efforts in man...y countries were frequently carried out in an ad hoc and nonstandardized fashion. In 2013, there were at least 2,200 different districts (of the 4,851 districts in the WHO African region) that still required mapping, and in many of these districts, more than one disease needed to be mapped. During its 3-year duration from January 2014 through the end of 2016, the project carried out mapping surveysfor one ormore NTDs in at least 2,500 districts in 37 African countries. At the end of 2016, most (90%) of the 4,851 districts had completed the WHO-required mapping surveys for the five targeted Preventive Chemotherapy (PC)-NTDs, and the impact of this accelerated WHO/AFRO NTD Mapping Project proved to be much greater than just the detailed mapping results themselves. Indeed, the AFRO Mapping
Project dramatically energized and empowered national NTD programs, attracted donor support for expanding these programs, and developed both a robust NTD mapping database and data portal. By clarifying the prevalence and burden
of NTDs, the project provided not only the metrics and technical framework for guiding and tracking program implementation and success but also the research opportunities for developing improved diagnostic and epidemiologic sampling tools for all 5 PC-NTDs—lymphatic filariasis, onchocerciasis, schistosomiasis, soil-transmitted helminthiasis, and trachoma.

L’enquête SMART Rapide a été réalisée dans la commune de Fada N’Gourma, chef-lieu de la province du Gourma dans la région de l’Est. C’est la commune de la région qui accueille le plus de personnes déplacées internes (PDI) depuis le début de la crise sécuritaire (85 574 PDIs à la ...date du 30 avril 2022)1 . Ces déplacées ont pour la plupart abandonnées leurs moyens d’existence et se retrouvent dans la précarité et sous l’assistance humanitaire et des populations hôtes.
La méthodologie SMART Rapide a été utilisé pour l’évaluation. Les secteurs/villages ont été sélectionnés par le logiciel ENA en utilisant la probabilité proportionnelle à la taille.
Quant aux ménages, ils ont été sélectionnés selon un processus de segmentation, d’échantillonnage aléatoire simple ou systématique. Les données ont été collectés du 13 au 15 juin 2022 par cinq équipes composées d’un chef d’équipe et d’un mesureur chacune. Les équipes ont été supervisées durant la collecte par des superviseurs. Les paramètres collectés étaient l’âge, le sexe, le poids, la taille, le périmètre brachial et la présence des œdèmes. Quatre grappes ont été inaccessibles due aux problèmes sécuritaires.
Au total, 24 grappes (avec l’utilisation des grappes de réserve), 235 ménages et 356 enfants ont été couverts. Les résultats montrent une prévalence de la malnutrition aiguë globale de 15,2% (11,2%-20,2%) selon le rapport poids/taille et 7,8% (5,0%-11,9%) selon le périmètre brachial. La malnutrition aiguë globale combinée est de 16,9% (12,9%-22,0%).

Cardiovascular disease (CVD) is often thought to be a problem of wealthy, industrialized nations. The term “cardiovascular disease” is used throughout the report to refer to cardiac disease, vascular diseases of the brain and kidney, and peripheral vascular disease. The report’s main focus is ...on the major contributors to global CVD mortality, coronary heart disease and stroke, and on the major modifiable risk factors for cardiovascular diseases. In fact, as the leading cause of death worldwide, CVD now has a major impact not only on developed nations but also on low and middle income countries, where it accounts for nearly 30 percent of all deaths. The terms “developed” and “high income countries” are used interchangeably throughout the report to refer to countries classified by the World Bank as high income economies. The terms “developing” and “low and middle income countries” are used interchangeably throughout the report to refer to countries classified by the World Bank as low, lower middle, and upper middle income economies. The increased prevalence of risk factors for CVD and related chronic diseases in developing countries, including tobacco use, unhealthy dietary changes, reduced physical activity, increasing blood lipids, and hypertension, reflects significant global changes in behavior and lifestyle. The term “chronic diseases” is used throughout the report to refer to CVD and the following related chronic diseases that share many common risk factors: diabetes, cancer, and chronic respiratory disease. These changes now threaten once-low-risk regions, a shift that is accelerated by industrialization, urbanization, and globalization. The potentially devastating effects of these trends are magnified by a deleterious economic impact on nations and households, where poverty can be both a contributing cause and a consequence of chronic diseases. The accelerating rates of unrecognized and inadequately addressed CVD and related chronic diseases in both men and women in low and middle income countries are cause for immediate action.

In recent years, Rwanda has been on the fast track to achieve major health improvements for its entire population. With the support of government agencies and various non-governmental partners, the Ministry of Health (MoH) has endeavored to decentralize Rwanda’s health system and bring health serv...ices closer to the people. Guided by multitude of national and international development frameworks, Rwanda’s healthcare successes include the establishment of a community health insurance scheme (mutuelle de santé), a system of cooperative-financed community health workers in every village, and interventions for researching, preventing, and treating diseases like HIV/AIDS, TB, and malaria.
As the MoH continues to design innovative means to reach and surpass its prescribed health outcome targets, it will hold as core principles the integration of service provision, the increase in healthcare capacity, and the attainment of sustainable funding sources. Rwanda is committed to achieving the Millennium Development Goals by 2015 and has declared Family Planning (FP) a national priority for poverty reduction and socioeconomic development of the country. Modern contraceptive use has more than quadrupled from 2005 to 2010, rising from 10% to 45%, but the government’s Economic Development and Poverty Reduction Strategy calls for an increase the modern contraceptive prevalence to 70% by 2016. While structural changes in health care and supply chains have led to noteworthy improvements in FP and other services, there are still many challenges that must be overcome. As such, a strategic plan is needed to coordinate FP efforts around a well-defined set of objectives and responsibilities.

Despite progress in improving antiretroviral therapy (ART) for people with HIV in Malawi, the burden of HIV infections and HIV treatment outcomes among key populations is suboptimal. Client-centered differentiated service delivery approaches may facilitate addressing HIV prevention and treatment nee...ds of key populations in Malawi.
Methods
De-identified program data routinely collected as part of the LINKAGES project–Malawi were assembled from October 2017 to September 2019. HIV case finding was compared across different testing modalities for each population. Poisson regression was used to estimate the association between testing modalities and ART initiation.
Results
Of the 18 397 people included in analyses, 10 627 (58%) were female sex workers (FSWs), 2219 (12%) were men who have sex with men (MSM), and 4970 (27%) were clients of FSWs. HIV case finding varied by modality and population, with index testing and enhanced peer outreach demonstrating high yield despite reaching relatively few individuals. FSWs who tested positive through risk network referral testing were more likely to initiate ART within 30 days compared with those who tested positive through clinic-based testing (adjusted risk ratio [aRR], 1.50; 95% CI, 1.23–1.82). For MSM, index testing (aRR, 1.45; 95% CI, 1.06–2.00) and testing through a drop-in center (aRR, 1.82; 95% CI, 1.19–2.78) were associated with 30-day ART initiation.
Conclusions
These data suggest that differentiated HIV testing and outreach approaches tailored to the needs of different key populations may facilitate improved ART initiation in Malawi. Achieving 0 new infections by 2030 suggests the need to adapt treatment strategies given individual and structural barriers to treatment for key populations with HIV in high-prevalence settings.
