Chagas disease is a parasitic, systemic, and chronic disease caused by the protozoan Trypanosoma cruzi, with risk factors strongly link to low socioeconomic factors. Chagas disease is considered a neglected tropical disease. It is endemic in 21 countries in the Americas, although the migration of in...fected people can transport the disease to non-endemic countries of America and the world.

Almost all populations are consuming too much sodium. The global mean intake of adults is 4310 mg/day sodium (equivalent to 10.78 g/day salt). This is more than double the World Health Organization recommendation for adults of less than 2000 mg/day sodium (equivalent to < 5 g/day salt).
- The prima...ry health effect associated with diets high in sodium is raised blood pressure, increasing the risk of cardiovascular diseases, gastric cancer, obesity, osteoporosis, Meniere’s disease, and kidney disease.
- An estimated 1.89 million deaths each year are associated with consuming too much sodium

WHO convened the fifth stakeholders meeting on the elimination of HAT due to infection with Trypanosoma brucei gambiense (g-HAT) and Trypanosoma brucei rhodesiense (r-HAT) in Geneva, Switzerland, on 7–9 June 2023. The meeting was held again in person after the coronavirus disease (COVID-19) pandem...ic and jointly for both forms of the disease. The previous meetings on g-HAT held in 2014, 2016 and 2018, as well as on r-HAT in 2015, 2017 and 2019, and jointly for g-HAT and r-HAT in 2021 (8) reinforced the partnership and commitment for HAT elimination and structured the mechanisms of collaboration within the WHO network for HAT elimination. The network includes NSSCPs, groups developing new tools, international and nongovernmental organizations involved in disease control, and donors.
Fewer than 1000 cases of HAT annually have been reported over the past 5 years, which is a historic achievement. The area at risk has been substantially reduced. The elimination of HAT as a public health problem at the global level has been achieved.
The new road map for neglected tropical diseases (NTDs) 2021−2030 (“the road map”) with the target to interrupt the transmission of g-HAT requires the strengthened and sustained efforts of all stakeholders, national authorities and partners, under WHO coordination. It will take disproportionally high efforts and innovative strategies to find the last cases of g-HAT and neutralize its transmission. Given the limited resources and other competing public health priorities, this is a challenge that requires our joint commitment.

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.”

The article "Can we prevent cardiovascular diseases in low- and middle-income countries?" by Claude Lenfant discusses the growing threat of cardiovascular diseases (CVDs) in developing countries. It highlights that while CVD is already the leading cause of death globally, low- and middle-income coun...tries are now facing rising CVD rates due to lifestyle changes associated with urbanization and economic growth. Lenfant advocates for a dual approach: identifying and treating high-risk individuals and promoting broad, population-wide prevention efforts focused on lifestyle changes such as reducing smoking, lowering salt intake, and increasing physical activity. He emphasizes that early, affordable preventive measures are essential to mitigate the impending CVD epidemic in these countries and prevent significant healthcare and economic strain.

The video "Cholera - Questions & Answers" by the World Health Organization (WHO) explains the essential aspects of cholera, an acute diarrheal disease caused by ingesting water or food contaminated with the Vibrio cholerae bacterium. It highlights the main symptoms, including severe watery diarrhea,... vomiting, and rapid dehydration, which can be fatal without proper treatment. Transmission occurs primarily through unsafe water and poor sanitation conditions. To prevent the disease, it is crucial to have access to clean drinking water, improve hygiene and sanitation, and use vaccination in high-risk areas. In case of infection, oral or intravenous rehydration is the primary treatment, while antibiotics are sometimes administered in severe cases. The video emphasizes the importance of rapid intervention and preventive measures to limit the spread of cholera and protect at-risk populations.

Revised working paper following AVAREF meeting February 2019.
WHO has published a roadmap aiming to coordinate partners’ actions and contributions to the licensing and roll-out of Merck’s Ebola vaccine (VSV-ZEBOV) in African countries. The vaccine was developed during the West Africa Ebola epi...demic of 2014-2016, during which more than 11 000 people lost their lives to the disease. The vaccine was tested in European and African countries at the time and is currently used under an “expanded access” protocol in the Democratic Republic of Congo.
WHO will expedite prequalification and licensing of the vaccine for use in countries at risk of Ebola outbreaks and will coordinate work between those countries’ regulatory authorities and the European Medicines Agency and the US Food and Drug Administration.

Dengue is the fastest spreading, mosquito-borne viral infectious disease worldwide, with remarkable morbidity and mortality. In the past decades, profound contributions have been made towards understanding its epidemiology, including disease burden and distributions, risk factors, and control and pr...evention practices. Dengue continues to disseminate to new areas, including high latitude regions, and a new serotype (dengue virus serotype 5) has been identified. Vaccine research has made new progress, in which the licensed yellow fever and dengue virus quadrivalent chimeric vaccine is now under further safety assessment. In disease surveillance, because of its operational simplicity, rapidity, capability, and utility as an indicator of disease severity, dengue virus NS1 antigen detection has great promotion and application value among primary health care institutions. Vector control progress has driven new breakthroughs in biotechnology, including Wolbachia-infected Aedes and genetically modified Aedes. Both Aedes variants have been used to block transmission of the dengue virus through population replacement and suppression. In the future, vector control should still be pursued as a key measure to prevent transmission, along with anti-viral drug and vaccine research.

We developed an integrated vector surveillance (IVS) proposal for cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL) in the Americas, based on eco-epidemiological studies conducted by researchers of the Leishmaniasis Research Network of Argentina. For CL, the transmission was explained in ...the framework of the edge effect, the increase of vectors and risk of exposure at ecotones and environmental interfaces, and typified as ephemeral, transient, or permanent edges, supporting a cost-effective IVS strategy for early warning of CL outbreaks through an environmental modification alert network, which includes multiple sources of information and actors. In relation to VL, the earliest colonization sites and spatial distribution were explained by modeling and forecasting the most likely hotspots, persistent in time and space, and modulated by environmental variables. Therefore, for VL, a scalar strategy of critical site selection is proposed from a “city” scale based on secondary sources such as remote sensing for the definition of possible areas to monitor and intervene, a scale of restriction from possible to most likely areas through local knowledge, and a “focal site” scale of trap placement through field observation; in this way, IVS activities are carried out at a few sites of the urban landscape and allow a sustainable program.
