Omicron BA.2 sub-variant more infectious but no more severe – Africa CDC
Feb. 24, 2022
The Omicron BA.2 sub-variant of COVID-19 appears to be more infectious than the original BA.1 sub-variant, but does not cause more severe disease, the head of Africa’s top public health body said on Thursday, citing data from South Africa.
“South Africa is reporting that it is more transmissible than the BA.1 variant, but interestingly and very encouragingly the severity seems to be the same,” said Dr. John Nkengasong, head of the Africa Centres for Disease Control and Prevention.
South Africa was one of the first countries to detect the Omicron variant of COVID-19, which has since swept around the globe and become dominant in most places.
Nkengasong said the trend may be linked to the BA.2 sub-variant, but did not elaborate.
