Un virus qui provoque des sympt\u00f4mes mortels de type Ebola chez certains singes serait sur le point de se propager \u00e0 l\u2019Homme.<\/p>\n
Selon des chercheurs de l\u2019Universit\u00e9 du Colorado-Boulder, aux \u00c9tats-Unis, \u00ab\u00a0ce virus animal a r\u00e9ussi \u00e0 p\u00e9n\u00e9trer dans les cellules humaines, \u00e0 se multiplier et \u00e0 \u00e9chapper \u00e0 certains des m\u00e9canismes immunitaires importants qui devraient nous prot\u00e9ger contre un virus animal. C’est assez rare\u00a0\u00bb.<\/p>\n
Pour l’auteur principal de la recherche, Sara Sawyer, le virus SHFV a d\u00e9j\u00e0 provoqu\u00e9 plusieurs \u00e9pid\u00e9mies mortelles dans des colonies de macaques en captivit\u00e9.<\/p>\n
Ses sympt\u00f4mes se rapprochent de ceux d\u00e9clench\u00e9s par le virus Ebola (fi\u00e8vre, faiblesse intense, douleurs musculaires, vomissements, diarrh\u00e9es\u2026).<\/p>\n
Pour l\u2019heure, les chercheurs ne connaissent pas les cons\u00e9quences si le virus venait \u00e0 changer d\u2019esp\u00e8ce, mais ils \u00e9voquent des similitudes profondes avec le VIH, dont le pr\u00e9curseur est \u00e9galement n\u00e9 chez des singes.<\/p>\n
D\u2019autres virus potentiellement transmissibles ont r\u00e9cemment \u00e9t\u00e9 d\u00e9couverts comme Khosta-2 ou Langya henipavrus.<\/p>\n
\u00ab\u00a0Le Covid n’est que le dernier \u00e9v\u00e9nement d’une longue s\u00e9rie de transmissions de l’animal \u00e0 l’Homme\u00a0\u00bb, souligne Sara Sawyer.<\/p>\n
La scientifique incite \u00e0 davantage surveiller les populations humaines en contact \u00e9troit avec des animaux porteurs du virus pour mieux anticiper si SHFV venait \u00e0 se propager \u00e0 l\u2019Homme.<\/p>\n
