Cependant, dans des endroits confin\u00e9s comme un restaurant, l&rsquo;air conditionn\u00e9 jouerait \u00e9galement un r\u00f4le capital dans la diss\u00e9mination des s\u00e9cr\u00e9tions respiratoires contenant de l&rsquo;ARN viral. C&rsquo;est ce que rapporte une r\u00e9cente lettre de recherche dans le journal Emerging Infections Disease.<\/div>\n<div>C&rsquo;est dans un restaurant climatis\u00e9 de 5 \u00e9tages, sans fen\u00eatres, localis\u00e9 en Chine que les contaminations ont eu lieu. Une famille venue de Whuan a voyag\u00e9 jusqu&rsquo;\u00e0 Guangzhou. Ici, elle a d\u00e9jeun\u00e9 dans ledit restaurant. Le lendemain, une personne de cette famille a manifest\u00e9 des sympt\u00f4mes typiques du Covid-19. Ce d\u00e9jeuner aurait favoris\u00e9 la contamination de 9 autres personnes : 4 membres de la m\u00eame famille et 5 personnes des deux autres familles \u00e0 proximit\u00e9, dont 2 personnes se trouvant en dessous de l&rsquo;air conditionn\u00e9.<\/div>\n<div>Le lendemain, 83 personnes ont d\u00e9jeun\u00e9 au m\u00eame \u00e9tage que ces personnes ; 10 ont d\u00e9velopp\u00e9 des sympt\u00f4mes par la suite. Les auteurs consid\u00e8rent la piste de la contamination par climatiseur plausible m\u00eame si d&rsquo;autres hypoth\u00e8ses ne peuvent pas \u00eatre \u00e9cart\u00e9es (contamination directe, puis contamination intra-famille, autres sc\u00e9narios). Enfin, les investigateurs rappellent que des contaminations suspectes similaires avaient d\u00e9j\u00e0 \u00e9t\u00e9 observ\u00e9es concernant le MERS-CoV.<\/div>\n<div><\/div>\n<div><strong>*Des futures recommandations pour les salles closes ?<\/strong><\/div>\n<div>\u00a0L&rsquo;\u00e9tude a cependant ses limites &#8212; pas d&rsquo;exp\u00e9rimentation simulant la voie de transmission a\u00e9roport\u00e9e, pas d&rsquo;\u00e9tudes s\u00e9rologiques, avec \u00e9couvillon, sur des membres asymptomatiques de la famille et d&rsquo;autres convives pour estimer le risque d&rsquo;infection directe &#8212; cependant, forts de cette potentielle d\u00e9couverte, les auteurs concluent que la transmission des gouttelettes a \u00e9t\u00e9 provoqu\u00e9e par une ventilation climatis\u00e9e.<\/div>\n<div>Le facteur cl\u00e9 de l&rsquo;infection \u00e9tait la direction du flux d&rsquo;air.
