Africa-Press – Cameroun.<\/strong><\/span>\u00a0<\/strong><\/span>Avec la reprise de l’\u00e9pid\u00e9mie de Covid-19 un peu partout en Europe, le coronavirus est \u00e0 nouveau au c\u0153ur de l’actualit\u00e9. Nouveau rebondissement dans cette s\u00e9rie qui semble sans fin : l’identification d’un variant hypermut\u00e9, B1.1.529 en Afrique du Sud. L’OMS se r\u00e9unit d’urgence ce 26 novembre 2021 pour \u00e9voquer son cas.<\/p>\n

Toutes les deux semaines, rejoignez Julie Kern, journaliste sant\u00e9 dipl\u00f4m\u00e9e d’un master en infectiologie, pour un tour d’horizon des derni\u00e8res actualit\u00e9s et des mesures adopt\u00e9es pour contrer la pand\u00e9mie.<\/p>\n

Il \u00e9tait inconnu la semaine derni\u00e8re. Il provoque une r\u00e9union d’urgence de l’Organisation mondiale de la sant\u00e9 ce 26 novembre 2021. Un nouveau variant du SARS-CoV-2 inqui\u00e8te particuli\u00e8rement les scientifiques car il est \u00ab hypermut\u00e9. \u00bb Il a \u00e9merg\u00e9 en Afrique du Sud, dans la r\u00e9gion de Johannesbourg aux alentours du 10 novembre. Au moment de la r\u00e9daction de ces lignes, 65 cas confirm\u00e9s sont r\u00e9pertori\u00e9s en Afrique du Sud, 6 au Botswana et 4 en Chine (sur l’\u00eele d’Hong Kong). C’est donc moins de 100 cas pour lesquels le g\u00e9nome est s\u00e9quenc\u00e9 et identifi\u00e9.<\/p>\n

L’OMS n’a pas encore statu\u00e9 sur le profil de ce variant : est-ce un variant d’int\u00e9r\u00eat (VOI) ou d’inqui\u00e9tude (VOC). S’il est consid\u00e9r\u00e9 comme un VOC, il se pourrait qu’il soit nomm\u00e9 variant Nu pour suivre la tradition des lettres grecques. En attendant, on l’appelle B.1.1.529, en r\u00e9f\u00e9rence \u00e0 sa lign\u00e9e phylog\u00e9n\u00e9tique.<\/p>\n

Plus de 30 mutations dans la prot\u00e9ine S de ce variant du SARS-CoV-2<\/b><\/p>\n

Les informations scientifiques sur B.1.1.529 sont tr\u00e8s limit\u00e9es et encore \u00e0 confirmer. Mais il poss\u00e8de un nombre cons\u00e9quent de mutations, plus de 30, dans sa prot\u00e9ine S, celle-l\u00e0 m\u00eame qui permet son attachement et son entr\u00e9e dans les cellules. Certaines de ces mutations sont pr\u00e9sentes dans les variants Alpha et Delta et par analogie, les scientifiques craignent qu’elles conf\u00e8rent aussi \u00e0 B.1.1.529 le pouvoir d’\u00e9chapper au syst\u00e8me immunitaire et d’amoindrir l’efficacit\u00e9 des vaccins.<\/p>\n

L’impact des mutations sur le comportement de ce nouveau variant est encore \u00e0 confirmer. Il y a encore peu d’information sur l’\u00e9tat de sant\u00e9 des personnes infect\u00e9es par B.1.1.529, et donc il est impossible de conclure sur la s\u00e9v\u00e9rit\u00e9 des sympt\u00f4mes qu’il provoque.<\/p>\n

Le successeur du variant Delta ?<\/b><\/p>\n

Plusieurs pays, dont la France, ont d\u00e9j\u00e0 annonc\u00e9 la suspension de leurs liaisons a\u00e9riennes avec l’Afrique du Sud et ses voisins pour \u00e9viter la propagation de B.1.1.529. Les cas confirm\u00e9s \u00e0 Hong Kong Island \u00e9taient des voyageurs en provenance du pays. Si l’\u00e9mergence de ce variant semble inqui\u00e9ter la communaut\u00e9 scientifique, le peu de donn\u00e9es \u00e0 disposition appelle \u00e0 la prudence. Il ne pourrait \u00eatre qu’un des nombreux variants du SARS-CoV-2 \u00e0 \u00e9merger sans outrepasser les autres.<\/p>\n

D’autres \u00e9tudes scientifiques sont n\u00e9cessaires pour savoir si nous sommes face \u00e0 un variant aussi contagieux que le variant Delta. En Afrique du Sud, le variant B1.1.529 semble se propager plus vite que ce dernier. Les prochaines semaines devraient nous en apprendre plus sur B.1.1.529.<\/p>\n
