Nova variante Eris da Covid-19
July 14, 2022 - Os casos de COVID estão a aumentar nos EUA, Europa e Ásia, tendo sido identificada como preocupante a variante EG.5 ou Eris – em disseminação e podendo tornar-se a forma dominante à medida que a imunidade baixa.
The WHO singled out Eris to be closely watched because of mutations that might make it more contagious or severe. It has an extra spike protein mutation which can give it a transmission advantage over other previously dominant variants, but also affects how antibodies neutralise the virus, possibly allowing it to evade immunity due to previous infection or vaccination.
Global EG.5 infections account for around 17% of total cases, up from just 1% in late May, and while it is generally no more dangerous than the earlier Omicron variant, U.S. hospitalisations have soared by 40% since a low in June, while still 90% lower than the January 2022 Omicron outbreak.
