Après plus de trois ans sans cas, Haïti a signalé le 2 octobre 2022 un ensemble de cas de choléra dans la zone métropolitaine de Port-au-Prince, alors que le pays était sur le point d'être déclaré exempt de choléra.
Cette résurgence du choléra en Haïti survient dans un contexte opérat...ionnel complexe, au milieu d'un environnement socio-politique instable marqué par des blocus, des pénuries de carburant, des activités de bandes criminelles et une insécurité galopante. Les troubles civils et le manque d'accès aux communautés touchées aggravent la crise humanitaire complexe et entravent les efforts de réponse d'urgence.

Considerable energy has been expended over the last two decades in developing methods for identifying the presence of asthma among participants in population studies. The objective of this endeavour has commonly been to enable epidemiological research on risk factors for asthma, with the ultimate ai...m of preventing the disease. However, there are other reasons for measuring the prevalence of asthma in populations, including the desire to assess the burden of disease attributable to asthma, to track changes over time, and to compare the prevalence among population groups defined by geographical, demographic or social factors. Two major international collaborative studies arising from this work have made major contributions to our knowledge about asthma

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.
