Onchocerca volvulus transmitted by repeated bites of infected blackflies (Simulium spp.). These blackflies breed along fast-flowing rivers and streams, close to remote villages located near fertile land where people rely on agriculture.
There is a need to reinforce skills of national and district... health workers to know and identify the disease, understand the risk factors according to the context and living conditions of the affected communities, and promote the implementation of public health interventions. With the shift from control to elimination, large areas in Africa require mapping to assess whether transmission is active, and treatment required. A sampling strategy named Onchocerciasis elimination mapping has been developed to help countries conduct those assessments and start treatment where needed.
This course examines the epidemiology of Onchocerciasis, clinical aspects, impact, diagnosis, treatment and control, elimination, public health interventions and role of community health workers

Small drinking-water supplies commonly experience operational, managerial, technical and resourcing challenges that impact their ability to deliver safe and reliable services. The needs and opportunities associated with these supplies therefore warrant explicit consideration in policies and regulati...ons.
These Guidelines, specifically tailored to small water supplies, build on over 60 years of guidance by the World Health Organization (WHO) on drinking-water quality and safety. They focus on establishing drinking-water quality regulations and standards that are health based and context appropriate; on proactively managing risks through water safety planning and sanitary inspections; and on carrying out independent surveillance. The guidance is intended primarily for decision-makers at national and subnational levels with responsibility for developing regulatory frameworks and support programmes related to these activities. Other stakeholders involved in water service provision will also benefit from the guidance in this document.
Designed to be practical and accessible, these Guidelines offer clear guidance that is rooted in the principle of progressive improvement. State-of-the-art recommendations and implementation guidance are provided, drawn from a comprehensive evidence review and established good practices. Additionally, case examples are provided from countries and areas around the world to demonstrate how the guidance in this publication has been implemented in practice in a wide variety of contexts.
Together with WHO’s 2024 Sanitary inspection packages – a supporting tool for the Guidelines for drinking-water quality: small water supplies, these Guidelines update and supersede WHO’s 1997 Guidelines for drinking-water quality. Volume 3: surveillance and control of community supplies. Key changes to this updated publication include a greater focus on preventive risk management and a broader range of small water supplies covered, including those managed by households, communities and professional entities.

Diabetes mellitus (DM) is a global epidemic with significant morbidity. Diabetic
retinopathy (DR) is the specific microvascular complication of DM and affects 1 in 3 persons with DM. DR remains a leading cause of vision loss in working adult populations. Patients with severe levels of DR are report...ed to have poorer quality of life and reduced levels of physical, emotional, and social well-being, and they utilize more health care resources.
Epidemiological studies and clinical trials have shown that optimal control of blood glucose, blood pressure, and blood lipids can reduce the risk of developing retinopathy and slow its progression. Timely treatment with laser photocoagulation, and increasingly, the appropriate use of intraocular administration of vascular endothelial growth factor (VEGF) inhibitors can prevent visual loss in vision- threatening retinopathy, particularly diabetic macular edema (DME). Since visual loss may not be present in the earlier stages of retinopathy, regular screening of persons with diabetes is essential to enable early intervention.

WHO today released its first roadmap to tackle postpartum haemorrhage (PPH) – defined as excessive bleeding after childbirth - which affects millions of women annually and is the world’s leading cause of maternal deaths.
Despite being preventable and treatable, PPH results in around 70 000 de...aths every year. For those who survive, it can cause disabilities and psychological trauma that last for years.
“Severe bleeding in childbirth is one of the most common causes of maternal mortality, yet it is highly preventable and treatable,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. “This new roadmap charts a path forward to a world in which more women have a safe birth and a healthy future with their families.”
The Roadmap aims to help countries address stark differences in survival outcomes from PPH, which reflect major inequities in access to essential health services. Over 85% of deaths from PPH happen in sub-Saharan Africa and South Asia. Risk factors include anaemia, placental abnormalities, and other complications in pregnancy such as infections and pre-eclampsia.
Many risk factors can be managed if there is quality antenatal care, including access to ultrasound, alongside effective monitoring in the hours after birth. If bleeding starts, it also needs to be detected and treated extremely quickly. Too often, however, health facilities lack necessary healthcare workers or resources, including lifesaving commodities such as oxytocin, tranexamic acid or blood for transfusions.
“Addressing postpartum haemorrhage needs a multipronged approach focusing on both prevention and response - preventing risk factors and providing immediate access to treatments when needed - alongside broader efforts to strengthen women’s rights,” said Dr Pascale Allotey, WHO Director for Sexual and Reproductive Health and HRP, the UN’s special programme on research development and training in human reproduction. “Every woman, no matter where she lives, should have access to timely, high quality maternity care, with trained health workers, essential equipment and shelves stocked with appropriate and effective commodities – this is crucial for treating postpartum bleeding and reducing maternal deaths.”

What is high blood pressure in pregnancy?
Blood pressure is the force of your blood pushing against the walls of your arteries as your heart pumps blood. High blood pressure, or hypertension, is when this force against your artery walls is too high. There are different types of high blood pressure ...in pregnancy:
Gestational hypertension is high blood pressure that you develop while you are pregnant. It starts after you are 20 weeks pregnant. You usually don't have any other symptoms. In many cases, it does not harm you or your baby, and it goes away within 12 weeks after childbirth. But it does raise your risk of high blood pressure in the future. It sometimes can be severe, which may lead to low birth weight or preterm birth. Some women with gestational hypertension do go on to develop preeclampsia.
Chronic hypertension is high blood pressure that started before the 20th week of pregnancy or before you became pregnant. Some women may have had it long before becoming pregnant but didn't know it until they got their blood pressure checked at their prenatal visit. Sometimes chronic hypertension can also lead to preeclampsia.
Preeclampsia is a sudden increase in blood pressure after the 20th week of pregnancy. It usually happens in the last trimester. In rare cases, symptoms may not start until after delivery. This is called postpartum preeclampsia. Preeclampsia also includes signs of damage to some of your organs, such as your liver or kidney. The signs may include protein in the urine and very high blood pressure. Preeclampsia can be serious or even life-threatening for both you and your baby.

Infections by the soil-transmitted helminths (STH), including Ascaris lumbricoides, Trichuris trichiura, Ancylostoma duodenale/Necator americanus (hookworms), and Strongyloides stercoralis, disproportionately affect children around the world. Because of their transmission associated with poor sanita...ry conditions and inadequate hygiene practices, higher burden of disease is seen in children from developing countries from sub-Saharan Africa, Southeast Asia, and Latin America. Approximately 267 million preschool-age children (PSAC) and 568 million school-age children (SAC) worldwide are at risk of STH infection as well as impaired child growth and cognitive development from A. lumbricoides, T. trichiura, and hookworm infections, and death due to severe S. stercoralis infection. Thus, their control is a global health priority.

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.

Humanitarian emergencies result in a breakdown of critical health-care services and often make vulnerable communities dependent on external agencies for care. In resource-constrained settings, this may occur against a backdrop of extreme poverty, malnutrition, insecurity, low literacy and poor infra...structure. Under these circumstances, providing food, water and shelter and limiting communicable disease outbreaks become primary concerns. Where effective and safe vaccines are available to mitigate the risk of disease outbreaks, their potential deployment is a key consideration in meeting emergency health needs. Ethical considerations are crucial when deciding on vaccine deployment. Allocation of vaccines in short supply, target groups, delivery strategies, surveillance and research during acute humanitarian emergencies all involve ethical considerations that often arise from the tension between individual and common good. The authors lay out the ethical issues that policy-makers need to bear in mind when considering the deployment of mass vaccination during humanitarian emergencies, including beneficence (duty of care and the rule of rescue), non-maleficence, autonomy and consent, and distributive and procedural justice

Testing and diagnosis of hepatitis B (HBV) and C (HCV) infection is the gateway for access to both prevention and treatment services, and is a crucial component of an effective response to the hepatitis epidemic. Early identification of persons with chronic HBV or HCV infection enables them to recei...ve the necessary care and treatment to prevent or delay progression of liver disease. Testing also provides an opportunity to link people to interventions to reduce transmission, through counselling on risk behaviours and provision of prevention commodities (such as sterile needles and syringes) and hepatitis B vaccination.
