The World Health Organization's cholera fact sheet provides essential information about cholera, an acute diarrheal infection caused by ingesting food or water contaminated with Vibrio cholerae bacteria. The disease remains a global public health threat, particularly in areas lacking safe water and ...adequate sanitation. While many infected individuals exhibit mild or no symptoms, severe cases can lead to rapid dehydration and death if untreated. Prevention focuses on ensuring access to clean water, proper sanitation, and hygiene practices. Effective treatment primarily involves prompt administration of oral rehydration solutions. The fact sheet also highlights the importance of surveillance, preparedness, and response strategies to control outbreaks.

In South and Central America, lymphatic filariasis (LF) is caused by Wuchereria bancrofti, which is transmitted by Culex quinquefasciatus, the only vector species in this region. Of the seven countries considered endemic for LF in the Americas in the last decade, Costa Rica, Suriname and Trinidad a...nd Tobago were removed from the World Health Organization list in 2011. The remaining countries, Brazil, Dominican Republic, Guyana and Haiti, have achieved important progress in recent years. Brazil was the first country in the Americas to stop mass drug administration (MDA) and to establish post-MDA surveillance. Dominican Republic stopped MDA in all LF-endemic foci: La Ciénaga and Southwest passed the third Transmission Assessment Survey (TAS) and the Eastern focus passed TAS-1 in 2018. Haiti passed the TAS and interrupted transmission in >80% of endemic communes, achieving effective drug coverage. Guyana implemented effective coverage in MDAs in 2017 and 2018 and in 2019 scaled up the treatment for 100% of the geographical region, introducing ivermectin in the MDA in order to achieve LF elimination by the year 2026. The Americas region is on its way to eliminating LF transmission. However, efforts should be made to improve morbidity management to prevent disability of the already affected populations.

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.

Excessive consumption of salt (more than 5 g per day) raises blood pressure, a major risk factor for cardiovascular diseases such as heart disease and stroke, and is the leading cause of death in the WHO European Region. Many countries in the Region have initiated national salt reduction strategies,... including public awareness campaigns, reformulation, and front-of-pack nutrition labelling. However, despite ongoing efforts, surveillance data indicate that salt intake still far exceeds the limits recommended by WHO to protect health.

Avec l’essor des traitements antirétroviraux (TAR) à base de dolutégravir (DTG) pour soigner les personnes vivant avec
le VIH dans le monde, il est important d’estimer la vitesse à laquelle la résistance acquise au DTG apparaît dans les
populations sous TAR. Bien que la résistance au DT...G ne soit pas apparue dans les populations naïves aux TAR incapables
de supprimer la charge virale dans les essais cliniques, certains éléments portent à croire que la résistance au
DTG peut émerger chez les personnes suivant des schémas thérapeutiques incluant le DTG. L’OMS recommande aux
pays qui étendent les TAR incluant le DTG d’accompagner ce déploiement d’une surveillance en routine de la pharmacorésistance

Many vaccines and drugs hold the promise of reducing mortality and morbidity among pregnant women and infants living in low- and middle-income countries (LMICs). However, sufficient information on the safety of drugs and vaccines in pregnant women is rarely available at the time of product licensure... or approval. To account for this, active safety surveillance efforts are needed during the post-licensure and post-approval
phase to assess the safety of drugs and vaccines in pregnant women and their offspring. Pregnancy exposure registries (PER) are used to monitor the safety of vaccines and drugs. PERs are observational studies that systematically collect health information on exposure to medical products such as drugs and vaccines during pregnancy. This review demonstrates that a number of resources presently exist in LMICs that perform active safety surveillance in pregnant populations. These results indicate such systems employ a wide variety of approaches, each with their own set of strengths and challenges, as summarized in the final section of the report.
