Omicron’s BA.2 ‘sub-variant’ one and a half times more contagious than original, Danish study finds

A Danish study confirms it: the sub-variant of Omicron BA.2 is one and a half times more contagious than the original BA.1.

“The study shows that if someone in your household is infected with BA.2, there is a 39% overall risk of another household member becoming infected within the first week. On the other hand, if the person is infected with BA.1, the risk is 29%,” the Danish Infectious Diseases Control Authority (SSI) said in a statement.

Finally, another conclusion drawn from the work of Danish scientists: vaccinated people, and particularly those who have received a booster, are much less likely to be infected.

Denmark lifts restrictions today

In Denmark, Omicron BA.2 has already dethroned BA.1 and a record number of cases has been observed. A dramatic 43% rise in new infections has been recorded in seven days.

However, this did not prevent the Scandinavian country from lifting all health restrictions from today, thanks in particular to the high vaccination coverage enjoyed by the Danes.
