D\u2019abord parce qu\u2019il se transmet par les moustiques qui b\u00e9n\u00e9ficient du r\u00e9chauffement. Mais aussi car lors des canicules, les points d\u2019eau se rar\u00e9fient. Les oiseaux et les moustiques se concentrent autour de ceux qui restent, ce qui favorisent la transmission. L\u2019ann\u00e9e 2026 est un signal d\u2019alarme.<\/p>\n<p><b>Doit-on s\u2019en inqui\u00e9ter<\/b><b>\u00a0<\/b><b>?<\/b><\/p>\n<p><b>Y.S. : <\/b>Oui, sans pour autant paniquer. Les cas augmentent. Les formes s\u00e9v\u00e8res et les d\u00e9c\u00e8s aussi. Mais nous n\u2019attendons pas d\u2019\u00e9pid\u00e9mie majeure. C\u2019est une mont\u00e9e progressive avec parfois des pics importants. Il faut \u00eatre vigilant, d\u00e9velopper des programmes de surveillance, des traitements et des vaccins. Pour l\u2019instant, il n\u2019existe qu\u2019un vaccin chez le cheval. Chez l\u2019humain\u00a0: aucun vaccin ni traitement.<\/p>\n<p><b>Par rapport \u00e0 la dengue ?<\/b><\/p>\n<p><b>Y.S. : <\/b>Les cas de dengue sont plus nombreux et plus largement r\u00e9partis g\u00e9ographiquement. Mais le virus du Nil occidental provoque plus de formes s\u00e9v\u00e8res car il atteint le cerveau et entra\u00eene des inflammations souvent fatales. Toutefois, une grosse diff\u00e9rence avec la dengue est qu\u2019un humain infect\u00e9 par le virus du Nil occidental ne le transmet pas s\u2019il est piqu\u00e9 par un moustique. Sa charge virale n\u2019est pas suffisante. Cela freine la transmission. C\u2019est plut\u00f4t une bonne nouvelle. Mais le virus peut se transmettre par don de sang ou d\u2019organe.<\/p>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"La Marseillaise&nbsp;: Avec 161 humains infect&eacute;s par le virus du Nil occidental en France, l&rsquo;ann&eacute;e 2026 marque un record&#8230;","protected":false},"author":1,"featured_media":47423,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[333],"tags":[207,343,239,1094,6179,240,284,569,419,416,1058,353,1615,1938,4258],"news-destination":[],"news-source":[475],"is_homepage":[],"ta_other":[],"class_list":["post-47422","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-environnement","tag-changement-climatique","tag-entretien","tag-herault","tag-maladies","tag-maladies-tropicales","tag-montpellier","tag-occitanie","tag-oiseaux","tag-rechauffement-climatique","tag-recherche-scientifique","tag-science","tag-sciences","tag-universite","tag-vaccins","tag-virus","news-source-website"],"_links":{"self":[{"href":"https:\/\/euapp01.newsmemory.com\/lamarseillaise\/news\/wp-json\/wp\/v2\/posts\/47422","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/euapp01.newsmemory.com\/lamarseillaise\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/euapp01.newsmemory.com\/lamarseillaise\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/euapp01.newsmemory.com\/lamarseillaise\/news\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/euapp01.newsmemory.com\/lamarseillaise\/news\/wp-json\/wp\/v2\/comments?post=47422"}],"version-history":[{"count":1,"href":"https:\/\/euapp01.newsmemory.com\/lamarseillaise\/news\/wp-json\/wp\/v2\/posts\/47422\/revisions"}],"predecessor-version":[{"id":47424,"href":"https:\/\/euapp01.newsmemory.com\/lamarseillaise\/news\/wp-json\/wp\/v2\/posts\/47422\/revisions\/47424"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/euapp01.newsmemory.com\/lamarseillaise\/news\/wp-json\/wp\/v2\/media\/47423"}],"wp:attachment":[{"href":"https:\/\/euapp01.newsmemory.com\/lamarseillaise\/news\/wp-json\/wp\/v2\/media?parent=47422"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/euapp01.newsmemory.com\/lamarseillaise\/news\/wp-json\/wp\/v2\/categories?post=47422"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/euapp01.newsmemory.com\/lamarseillaise\/news\/wp-json\/wp\/v2\/tags?post=47422"},{"taxonomy":"news-destination","embeddable":true,"href":"https:\/\/euapp01.newsmemory.com\/lamarseillaise\/news\/wp-json\/wp\/v2\/news-destination?post=47422"},{"taxonomy":"news-source","embeddable":true,"href":"https:\/\/euapp01.newsmemory.com\/lamarseillaise\/news\/wp-json\/wp\/v2\/news-source?post=47422"},{"taxonomy":"is_homepage","embeddable":true,"href":"https:\/\/euapp01.newsmemory.com\/lamarseillaise\/news\/wp-json\/wp\/v2\/is_homepage?post=47422"},{"taxonomy":"ta_other","embeddable":true,"href":"https:\/\/euapp01.newsmemory.com\/lamarseillaise\/news\/wp-json\/wp\/v2\/ta_other?post=47422"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
