The first data suggest that the Omicron mutation of coronavirus SARS-CoV-2 is more contagious than Delta mutation, the director of the Centers for Disease Control and Prevention said on Wednesday (CDC) Rochelle Wallenski.
The data from the first investigations show that Omicron has a doubling time of about two days, Waleski noted during today’s briefing of the journalists in the White House, according to Reuters.
So far cases of this variant have been confirmed in at least 36 States and health professionals expect that they will increase in the coming weeks, reports the APE BPE.
Experts are beginning to notice an increase in cases among fully vaccinated residents of nursing homes. Among those who have received the booster dose of the vaccine, however, the risk of infection is ten times lower, Wallenski added.
It is pointed out, finally, that it is estimated that the 3% all cases in the US are due to Omicron. Five days ago the CDC talked about just 43 Omicron cases in the country.
