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.

As countries aim to progress towards the Sustainable Development Goals (SDGs) and achieving universal health coverage, health inequities driven by racial discrimination and intersecting factors remain pervasive. Inequities experienced by indigenous peoples as well as people of African descent, Roma ...and other ethnic minorities are of concern globally; they are unjust, preventable and remediable.
Health systems themselves are important determinants of health and health equity. They can perpetuate health inequities by reflecting structural racism and discriminatory practices of wider society. For instance, systemic racism, implicit bias, misinformed clinical practice, or discrimination by health professionals contributes to health inequities. However, health systems can also be a leading force for tackling the inequities faced by populations experiencing racial discrimination.
Primary health care (PHC) is the essential strategy for reorientating health systems and societies to become healthier, equitable, effective and sustainable. In 2018, on the 40th anniversary of the Declaration of Alma-Ata, the World Health Organization (WHO) and the United Nations Children’s Fund (UNICEF) renewed the emphasis on PHC with their strategy,
WHO outlines 14 strategic and operational levers for policy-makers to strengthen PHC. Within each lever, there are multiple potential entry points for targeted actions to address racial discrimination, foster intercultural care, and reduce health inequities experienced by indigenous peoples as well as people of African descent, Roma and other ethnic minorities.

Brucellosis is widespread in both humans and livestock in many developing countries. The authors have performed a series of epidemiological studies on brucellosis in agro-pastoral areas in Tanzania since 2015, with the aim of the disease control. Previously, the potential of a community-based brucel...losis control initiative, which mainly consisted of the sale of cattle with experience of abortion and vaccinating calves, was assessed as being effective and acceptable based on a quantitative approach. This study was conducted to investigate the feasibility of community-based brucellosis control program using participatory rural appraisals (PRAs) and key-informant interviews. Four PRAs were performed together with livestock farmers and livestock and medical officers in 2017. In the PRAs, qualitative information related to risky behaviors for human infection, human brucellosis symptoms, willingness to sell cattle with experience of abortion, and willingness to pay for calf vaccination were collected, and a holistic approach for a community-based disease control project was planned. All of the communities were willing to implement disease control measures. To avoid human infection, education, especially for children, was proposed to change risky behaviors. The findings of this study showed that community-based disease control measures are promising.

The Covid-19 pandemic has so far infected more than 30 million people in the world, having major impact on global health with collateral damage. In Mozambique, a public state of emergency was declared at the end of March 2020. This has limited people's movements and reduced public services, leading ...to a decrease in the number of people accessing health care facilities. An implementation research project, The Alert Community for a Prepared Hospital, has been promoting access to maternal and child health care, in Natikiri, Nampula, for the last four years. Nampula has the second highest incidence of Covid-19. The purpose of this study is to assess the impact of Covid-19 pandemic Government restrictions on access to maternal and child healthcare services. We compared health centres in Nampula city with healthcare centres in our research catchment area. We wanted to see if our previous research interventions have led to a more resilient response from the community.
METHODS: Mixed-methods research, descriptive, cross-sectional, retrospective, using a review of patient visit documentation. We compared maternal and child health care unit statistical indicators from March-May 2019 to the same time-period in 2020. We tested for significant changes in access to maternal and child health services, using KrushKall Wallis, One-way Anova and mean and standard deviation tests. We compared interviews with health professionals, traditional birth attendants and patients in the two areas. We gathered data from a comparable city health centre and the main city referral hospital. The Marrere health centre and Marrere General Hospital were the two Alert Community for a Prepared Hospital intervention sites.
RESULTS: Comparing 2019 quantitative maternal health services access indicators with those from 2020, showed decreases in most important indicators: family planning visits and elective C-sections dropped 28%; first antenatal visit occurring in the first trimester dropped 26%; hospital deliveries dropped a statistically significant 4% (p = 0.046), while home deliveries rose 74%; children vaccinated down 20%.
CONCLUSION: Our results demonstrated the negative collateral effects of Covid-19 pandemic Government restrictions, on access to maternal and child healthcare services, and highlighted the need to improve the health information system in Mozambique.

The health-care system collapse underway in Venezuela is a cause of utmost concern for its people and, increasingly, for the wider region. Declines in provision of basic services, such as ...childhood immunisation, malaria control, water, sanitation, and nutritional support, have led to increasing morbidity and mortality rates from an array of preventable diseases, including malaria, measles, and diphtheria. Secondary and tertiary care have also been greatly affected, due to declining investment, out-migration of providers, and spiralling hyperinflation that has driven the country and its people into poverty.1 As is so often, and so tragically, the case, the most affected populations have been the most vulnerable: infants and children, their mothers, the poor (now the great majority of the populations), and indigenous people

Because of the limited access to more powerful diagnostic tools, there is a paucity of data regarding the burden of fungal infections in Burkina Faso. The aim of this study was to estimate the incidence and prevalence of serious fungal infections in this sub-Saharan country. We primarily used the na...tional demographic data and performed a PubMed search to retrieve all published papers on fungal infections from Burkina Faso and its surrounding West African countries. Considering the prevalence of HIV infection (0.8% of the population) and a 3.4% incidence of cryptococcosis in hospitals, it is estimated that 459 patients per year develop cryptococcosis. For pneumocystosis, it is suggested that 1013 new cases occur every year. Taking into account the local TB frequency (population prevalence at 0.052%), we estimate the prevalence of chronic pulmonary aspergillosis at 1120 cases. Severe forms of asthma with fungal sensitization and allergic bronchopulmonary aspergillosis are estimated to affect 7429 and 5628 cases, respectively. Vulvovaginal candidiasis may affect 179,000 women, and almost 1,000,000 children may suffer from tinea capitis. Globally, we estimate that roughly 1.4 million people in Burkina Faso (7.51% of the population) suffer from a serious fungal infection. These data should be used to drive future epidemiological studies, diagnostic approaches, and therapeutic strategies.

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.

In 1989, the Republic of Benin was facing a great social and
economical crisis. Civil servants of all the sectors in public
administration were on strike. People did not know where to
go for their health care. Salaries were not paid for more than
six months and life for the general population wa...s very dificult.
The country was about to degenerate into civil war as a
result of the civil unrest in the country.
Thanks to the assistance from the French, and Canadian
and American Mennonite missionaries, the Bethesda Health
Centre was started in 1990 with US$ 1,000 granted by theses
partners. Today, the Health Centre of Bethesda has expanded
and has become a large Hospital in Cotonou. It hosts each
year about 100,000 patients and has developed the department
of paediatrics, ophthalmology, stomatology, cardiology,
obstetrical gynaecology, X-rays, etc. The Hospital has also
put in place an AIDS service which has been promoted by the
government to the status of an AIDS Treatment Centre.
In an integrated vision, Bethesda has established other departments.
In 1993, the Sanitation department was established
to implement sanitation and environmentally-friendly
projects aimed at reducing the high incidence of some diseases
frequently treated at the hospital. In 1996, the decision
was made to establish a micro-inance department called
PEBCo. This initiative, which currently has 10,000 clients,
uses community savings to promote income-generating activities.
Since many women were obliged to use the loans for
family needs (health care, children schooling, etc.), they were
unable to reimburse them as planned. Hence the Bethesda
non-government organization (NGO) recently began an initiative
to provide a community-based health insurance option
for the population in 2006. There are now 12,000 members.
This paper focuses on the presentation of Benin and the program,
but also describes how the project could be better improved
and what were its beneits and impacts.

Key facts
- A healthy diet helps to protect against malnutrition in all its forms, as well as noncommunicable diseases (NCDs), including diabetes, heart disease, stroke and cancer.
- Unhealthy diet and lack of physical activity are leading global risks to health.
- Healthy dietary practices start... early in life – breastfeeding fosters healthy growth and improves cognitive development, and may have longer term health benefits such as reducing the risk of becoming overweight or obese and developing NCDs later in life.
- Energy intake (calories) should be in balance with energy expenditure. To avoid unhealthy weight gain, total fat should not exceed 30% of total energy intake (1, 2, 3). Intake of saturated fats should be less than 10% of total energy intake, and intake of trans-fats less than 1% of total energy intake, with a shift in fat consumption away from saturated fats and trans-fats to unsaturated fats (3), and towards the goal of eliminating industrially-produced trans-fats (4, 5, 6).
- Limiting intake of free sugars to less than 10% of total energy intake (2, 7) is part of a healthy diet. A further reduction to less than 5% of total energy intake is suggested for additional health benefits (7).
- Keeping salt intake to less than 5 g per day (equivalent to sodium intake of less than 2 g per day) helps to prevent hypertension, and reduces the risk of heart disease and stroke in the adult population (8).
- WHO Member States have agreed to reduce the global population’s intake of salt by 30% by 2025; they have also agreed to halt the rise in diabetes and obesity in adults and adolescents as well as in childhood overweight by 2025 (9, 10).

A full-scale military attack (invasion) of Ukraine was started by Russia in the night of February 23/24, 2022. Cities, towns and other targets in all regions of Ukraine have been shelled or attacked with rockets, and columns of military vehicles have been invaded the country from three directions (n...orth, east and south). Fighting continues across all regions with Russian forces capturing cities along the south coast but facing tougher resistance in the northern parts of the country. Residential areas in cities such as Kharkiv, Kyiv and Mykolaiv have been shelled and destroyed, with many lives have been lost. Ongoing negotiations between the governments of Ukraine and Russia have yielded no results in bringing a ceasefire or end to the conflict.

Les infections au SRAS-CoV-2 chez les enfants et les adolescents provoquent une maladie moins grave et moins de décès que chez les adultes. Bien qu'une évolution moins grave de l'infection soit un résultat positif, on s'inquiète du fait que des symptômes légers aient pu conduire à moins de t...ests, ce qui a entraîné un nombre moins important de cas identifiés de COVID-19 chez les enfants. Si les enfants présentant des symptômes légers ou inexistants transmettent la maladie, ils peuvent agir comme des vecteurs de transmission au sein de leur communauté. Il est essentiel de comprendre les symptômes, l'infectivité et les modes de transmission du SRAS-CoV-2 chez les enfants et les adolescents pour développer, adapter et améliorer les mesures de contrôle du COVID-19 à tous les âges. Ce document est un résumé des connaissances actuelles concernant l'acquisition et la transmission de l'infection par le SRAS-CoV-2 et les symptômes de la maladie COVID-19 chez les enfants et les adolescents. Il vise à éclairer les décisions, en fonction des contextes locaux, sur la meilleure façon de maintenir ouvertes les écoles, les jardins d'enfants et les crèches et sur les conseils à appliquer en matière de mixité intergénérationnelle.
