Omicron sub-variant BA.2 more infectious than original version

Omicron sub-variant BA.2 more infectious than original version

Copenhagen, Feb 1 (Prensa Latina) Omicron sub-variant BA.2 would be more infectious than the original one (BA.1), according to a study released Tuesday by the University of Copenhagen and the Statens Serum Institut.

The research found that BA.2 spread between members of the same household within seven days of the first infection in 39%, compared with 29% of cases for the original version of Omicron.

The study concluded that BA.2 was substantially more transmissible than BA.1 and it also possessed immune-evasive properties that further reduce the protective effect of vaccination against infection.

According to specialist Camilla Holten, individuals who agreed to get vaccinated, especially those who have received a booster dose, are at much lower risk of being infected and are less likely to transmit the disease.

The Danish study, which has not yet been validated by other experts, monitored the spread of 8,541 household infections between late December 20, 2021 and January 18.
