L’orthopoxvirus simien ou virus de la variole du singe (MPXV), est un virus à ADN double brin qui appartient au genre Orthopoxvirus de la famille
des Poxviridés. Les poxvirus causent des maladies chez l’espèce humaine et beaucoup d’autres animaux ; l’infection se manifeste généralement... par la formation de lésions, de nodules cutanés ou d’une éruption cutanée disséminée. Les autres espèces d’orthopoxvirus (OPXV) pathogènes pour l’être humain comprennent le virus de la variole bovine et le virus variolique (responsable de la variole, qui a été éradiquée). Le virus de la vaccine est également un OPXV qui a été utilisé pour la vaccination humaine, et a été un outil essentiel pour l’éradication de la variole, obtenue en 1980. Le MPXV doit son nom au fait qu’il a été identifié pour la première fois chez le singe. Le MPXV se retrouve principalement chez les rongeurs, mais son réservoir reste indéterminé. Il existe deux clades connus du MPXV, l’un endémique en Afrique de l’Ouest, et l’autre dans la région du bassin du Congo.

The report provides an epidemiological update on cholera outbreaks in Haiti as of January 17, 2023. Since the first confirmed cases in October 2022, Haiti has reported 24,232 suspected cases, including 1,742 confirmed cases and 483 deaths. The most affected areas are in the Ouest Department, particu...larly Port-au-Prince. Children aged 1 to 4 years are the most affected group. The ongoing humanitarian crisis, security issues, and limited access to healthcare have worsened the outbreak, hindering epidemiological surveillance and case reporting. The PAHO/WHO is working with Haitian authorities to respond to the outbreak and mitigate its spread.

The document presents Cameroon's National Response Plan for the 2018 cholera outbreak, covering August to October 2018. It highlights the epidemiological situation, with outbreaks reported in the North and Central regions and a total of 109 suspected cases and 9 deaths by July 2018. The plan outline...s strategies for controlling the epidemic, including epidemiological surveillance, improved access to clean water, sanitation, mass vaccination, community awareness campaigns, and hospital and community-based treatment.
The response is coordinated by the Ministry of Public Health, WHO, and various partners, focusing on early detection, rapid response, and multi-sectoral collaboration. Challenges include poor sanitation, limited healthcare infrastructure, and cross-border disease transmission risks. The plan emphasizes resource mobilization, monitoring, and evaluation to contain the outbreak and prevent future cases.

The article investigates the global burden and risk factors of chronic obstructive pulmonary disease (COPD). It emphasizes that COPD is a leading cause of morbidity and mortality worldwide, with significant health and economic impacts. The study identifies smoking as the primary risk factor, but als...o highlights other contributors such as occupational exposure, air pollution, and respiratory infections. The authors discuss variations in COPD prevalence and mortality rates across different regions, influenced by socioeconomic and environmental factors. The article calls for comprehensive public health strategies to reduce exposure to risk factors and improve early diagnosis and management to curb the global impact of COPD.

Asthma has a significant impact on people of all ages, particularly children. A lack of universally accepted case definition and confirmatory tests and a poor understanding of major risks interfere with a global response. We aimed to provide global estimates of asthma prevalence and cases in 2019 ac...ross four main epidemiological case definitions – current wheezing, ever wheezing, current asthma, and ever asthma. We further investigated major associated factors to determine regional and national distributions of prevalence and cases for current wheezing and ever asthma.
