Un nouveau coronavirus, similaire au covid-19, alerte la communaut\u00e9 scientifique. Selon certains chercheurs, ce virus pourrait \u00eatre transmissible \u00e0 l\u2019humain.<\/em><\/strong><\/em><\/p>\n\n\n\n

Depuis la pand\u00e9mie du coronavirus d\u00e9clar\u00e9e en 2020 partout dans le monde, les scientifiques redoutent la propagation d\u2019une nouvelle zoonose qui pourrait \u00eatre transmise \u00e0 l\u2019Homme.<\/p>\n\n\n\n

Le HKU5-CoV-2, d\u00e9tect\u00e9 chez des chauves-souris, est un nouveau coronavirus qui poss\u00e8de une caract\u00e9ristique similaire coronavirus mais pour le moment, aucun cas d\u2019infection chez l\u2019\u00eatre humain n\u2019a \u00e9t\u00e9 identifi\u00e9.<\/p>\n\n\n

\"\"<\/figure>\n<\/div>\n\n\n

Dans une \u00e9tude publi\u00e9e dans la revue scientifique am\u00e9ricaine Cell, ce virus qui appartient au sous-genre Merbecovirus, qui inclut \u00e9galement le virus responsable du syndrome respiratoire du Moyen-Orient (Mers-CoV). Ce dernier a un taux de mortalit\u00e9 de 35 %, selon l\u2019Organisation mondiale de la sant\u00e9 (OMS) et s\u2019est transmis des chameaux \u00e0 l\u2019humain par contact physique.<\/p>\n\n\n\n

La d\u00e9couverte de ce virus a \u00e9t\u00e9 r\u00e9alis\u00e9e par une \u00e9quipe de chercheurs chinois dirig\u00e9e par la virologue Shi Zhengl, et plusieurs instituts de recherche chinois ont suivi le pas, notamment le laboratoire de Guangzhou, l\u2019acad\u00e9mie des sciences de Guangzhou, mais aussi l\u2019Institut de virologie de Wuhan, qui a \u00e9t\u00e9 au c\u0153ur de l\u2019actualit\u00e9 et de la pol\u00e9mique lorsque la pand\u00e9mie du coronavirus s\u2019est propag\u00e9e dans le monde.<\/p>\n\n\n\n

Selon les recherches, le HKU5-CoV-2 utilise la m\u00eame prot\u00e9ine r\u00e9ceptrice ACE2 que le Sars-CoV-2, \u00e0 l\u2019origine du Covid-19. Cette prot\u00e9ine est celle responsable de la p\u00e9n\u00e9tration dans le corps humain.<\/p>\n\n\n\n

Les auteurs de l\u2019\u00e9tude ont fait des tests ayant r\u00e9v\u00e9l\u00e9 que des cellules humaines pr\u00e9sentant des niveaux \u00e9lev\u00e9s de cette prot\u00e9ine dans des tubes \u00e0 essai, ainsi que des mod\u00e8les d\u2019intestins ou des voies respiratoires humaines, ont \u00e9t\u00e9 infect\u00e9es par ce type de coronavirus.<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

Toutefois, certains scientifiques mettent de c\u00f4t\u00e9 la possibilit\u00e9 d\u2019une transmission humaine pour l\u2019heure, soulignant que l\u2019immunit\u00e9 existante contre des virus similaires au Sars et la faible affinit\u00e9 de liaison du HKU5-CoV-2 au r\u00e9cepteur ACE2 humain, r\u00e9duisent sa transmission \u00e0 l\u2019humain, mais ne rejettent pas des mutations ou d\u2019autres formes de virus similaires qui pourraient avoir cette capacit\u00e9.<\/p>\n\n\n\n
