The study also shows that vaccinated people, and in particular those who received the booster dose, are less likely to be infected.
The “subvariant” of omicron, BA.2, is more contagious than the original BA.1, according to a Danish study published Monday.
“The study shows that if one person in a household is infected with BA.2, there is an overall 39% risk that another family member will be infected during the first week. On the contrary, if the person is infected by BA.1, the risk is 29%, ”said the Danish Infectious Diseases Control Authority (SSI) in a statement.
Dominant in Denmark, where it overtook omicron, BA.2 is preliminary estimated to be 1.5 times more contagious than BA.1, the SSI revealed on January 26.

“Unvaccinated people may also be more likely to be infected by BA.2 relative to BA.1,” added Camilla Holten Møller, a doctor at SSI, quoted in the statement.
The study also shows that vaccinated people, and in particular those who received the booster dose, are less likely to be infected, he stressed.
Despite a record number of cases, the 43% increase in new infections registered in seven days, the Scandinavian country of 5.8 million inhabitants is ready to lift all restrictions on Tuesday, arguing the strong coverage of vaccines and the lower severity of the omicron variant. (I)
