In the context of an unprecedented event such as the COVID-19 pandemic, at present, the effectiveness of stringent social distancing and international traffic-related measures in decreasing the rate of spread of SARS-CoV-2, and related mortality, is inferred from empiric observations of their applic...ation in countries experiencing different transmission scenarios (e.g., Australia, China, Germany, Italy, New Zealand, and Spain). Such observations are consistent with and corroborated by mathematical models.

The WHO Guidance for Conducting a Country COVID-19 Intra-Action Review (IAR) was developed to guide countries to conduct periodic review(s) of their national and subnational COVID-19 response, so countries do not miss critical opportunities for learning and improvement to better respond to the COVID...-19 outbreak in their countries, especially as the possibility of a protracted pandemic becomes increasingly probable. The IAR is a country-led facilitated process conducted during the COVID-19 outbreak in-country, bringing together a small group of COVID-19 responders with knowledge of the public health response pillars under review. Although IARs can be conducted online or face-to-face, the online format is recommended, especially if community transmission remains high in the country. The IAR will identify practical areas for immediate remediation and sustained improvement of the ongoing response.

La schistosomiase est une parasitose aiguë et chronique provoquée par des vers (trématodes) du genre Schistosoma. Selon les estimations, au moins 251,4 millions de personnes avaient besoin d’un traitement préventif en 2021. Le traitement préventif, qui devrait être renouvelé pendant un cert...ain nombre d’années, permettra de réduire et de prévenir la morbidité. La transmission de la schistosomiase est avérée dans 78 pays. Cependant, la chimioprophylaxie de la maladie, dont le but est de traiter à grande échelle les populations et les communautés, n’est nécessaire que dans 51 pays d’endémie où la transmission est de modérée à forte.

Principaux faits
D’après les estimations, 6 à 7 millions de personnes dans le monde sont infectées par Trypanosoma cruzi (T. Cruzi), le parasite responsable de la maladie de Chagas. La plupart de ces personnes vivent en Amérique latine.
La transmission à l’être humain se fait principalem...ent, en Amérique latine, par l’intermédiaire d’un insecte appelé triatome, qui peut être porteur de T. cruzi.
Parmi les autres modes de transmission de la maladie de Chagas, figurent : la transmission orale (par voie alimentaire), la transfusion de sang ou de produits sanguins, la transmission mère-enfant (congénitale), la transplantation d’organes et les accidents de laboratoire.
La maladie de Chagas ne touchait auparavant que des zones rurales de la Région des Amériques, et surtout de l’Amérique latine. Ces dernières décennies, toutefois, les mouvements de population ont fait que la plupart des personnes infectées sont des habitants de zones urbaines (urbanisation) et que la maladie s’est propagée à d’autres continents (où T. cruzi se transmet par des voies non vectorielles).
L’infection à T. cruzi est curable si un traitement est instauré rapidement après l’infection.
Chez les personnes infectées de façon chronique, un traitement antiparasitaire peut éventuellement prévenir ou enrayer la progression de la maladie, et éviter sa transmission, notamment de la mère à l’enfant.
Jusqu’à 30 % des personnes infectées de façon chronique présentent des troubles cardiaques, et jusqu’à 10 % d’entre elles souffrent de troubles digestifs et/ou neurologiques, ce qui peut imposer un traitement particulier.
Les principales méthodes de prévention de la maladie de Chagas en Amérique latine sont la lutte antivectorielle ainsi que d’autres stratégies visant à réduire la transmission vectorielle.
Dans le monde entier, le dépistage sanguin joue un rôle crucial dans la prévention de l’infection par transfusion ou transplantation d’organes.
Il est essentiel de détecter et de traiter l’infection chez les femmes et les filles en âge de procréer, ainsi que de soumettre tout nouveau-né et ses frères et sœurs à un dépistage dans le cas où la mère est infectée et n’a jamais reçu de traitement antiparasitaire.
Certains facteurs socio-économiques et environnementaux influent fortement sur la maladie de Chagas, dont la propagation et les différentes dimensions interdépendantes justifient la nécessité de mettre en œuvre des stratégies de lutte multisectorielles.
Quelques pays ont mis en place la notification et la surveillance des cas aigus et chroniques et des voies de transmission actives, qui sont essentielles à la lutte contre la maladie de Chagas.

Rabies is a vaccine-preventable, zoonotic, viral disease affecting the central nervous system. Once clinical symptoms appear, rabies is virtually 100% fatal. In up to 99% of cases, domestic dogs are responsible for rabies virus transmission to humans. Yet, rabies can affect both domestic and wild an...imals. It spreads to people and animals via saliva, usually through bites, scratches or direct contact with mucosa (e.g. eyes, mouth or open wounds). Children between the age of 5 and 14 years are frequent victims.

La vidéo "Choléra - Questions & Réponses" de l'Organisation Mondiale de la Santé (OMS) explique les aspects essentiels du choléra, une maladie diarrhéique aiguë causée par l'ingestion d'eau ou d'aliments contaminés par la bactérie Vibrio cholerae. Elle met en avant les principaux symptôme...s, notamment une diarrhée aqueuse sévère, des vomissements et une déshydratation rapide, pouvant être mortelle sans traitement adéquat. La transmission se fait principalement par l’eau insalubre et les mauvaises conditions sanitaires. Pour prévenir la maladie, il est essentiel d'avoir accès à de l'eau potable, d'améliorer l'hygiène et l'assainissement, et d'utiliser la vaccination dans les zones à haut risque. En cas d'infection, la réhydratation orale ou intraveineuse est le traitement principal, tandis que les antibiotiques sont parfois administrés dans les cas graves. La vidéo insiste sur l'importance d'une intervention rapide et de mesures préventives pour limiter la propagation du choléra et protéger les populations à risque.

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.

Zika virus is primarily transmitted by the Aedes species of mosquito which is also responsible for the spread of dengue, Chikungunya and yellow fever viruses. In most areas, the primary vector of these viruses is Aedes aegypti, with Aedes albopictus a proven or potential vector in some settings. Wel...l-implemented vector control against Aedes using existing tools effectively reduces the transmission of viruses spread by these vectors. Pilot studies are being undertaken on new tools which have potential for future reductions in Aedes populations

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.

PLoS Negl Trop Dis 13(10): e0007694. In 2005, the World Health Organization (WHO) recognized Chagas disease (CD; Trypanosoma cruzi infection) as a neglected tropical disease (NTD) [1] and included it into the global plan to combat NTDs [2]. The Target 3.3 of the United Nations Sustainable Developmen...t Goals (UN/SDG) aims at ending the epidemics of NTDs by 2030 [3]. Mother-to-child (congenital/connatal) transmission is currently the main mode of transmission of T. cruzi over blood transfusions and organ transplantations in vector-free areas within and outside Latin America (LA). Based on recent demonstrations that congenital transmission can be prevented [4–7], WHO has shifted its objective, in 2018, from control to elimination of congenital CD (cCD).

Lymphatic filariasis is a vector-borne neglected tropical disease that causes damage of the lymphatic system and can lead to lymphoedema (elephantiasis) and hydrocele in infected individuals. The global baseline estimate of persons affected by lymphatic filariasis is 25 million men with hydrocele an...d over 15 million people with lymphoedema. At least 36 million persons remain with these chronic disease manifestations. The disease is endemic in 72 countries. In 2016, an estimated total population of 856 million were living in areas with ongoing transmission of the causative filarial parasites and requiring mass drug administration (MDA). Lymphatic filariasis disfigures and disables, and often leads to stigmatization and poverty. Hundreds of millions of dollars are lost annually due to reduced productivity of affected patients. WHO has ranked the disease as one of the world’s leading causes of permanent and long-term disability.
