South Africa feels a sense of relief as omicron cases follow a pattern of very steep upward increase, followed by a short period of a month, and then a very steep decrease. Cases in South Africa with a population of 60 million, about the size of Britain, dropped from 27,000 at the peak to about 15,000 on December 21, 2021. The area around Johannesburg was hardest hit. The median age is 27 years in South Africa, 40 in UK and 43 in Italy. With younger populations in India and parts of Asia South African population demographic is closer to India than it is to Europe where populations are much older. Scientists do not want to extrapolate from the South African experience with Omicron for this reason. Immunity from vaccination and prior infection could be contributory causes to the less severity of omicron say NCID scientists.

"In South Africa this is the epidemiology. Omicron is behaving in a way that is less severe," says Dr. Cheryl Cohen, of the National Institute for Communicable Diseases (NCID). "Compellingly together our data really suggest a positive story of a reduced severity of omicron compared to other variants," he said at a conference with other scientists on Wednesday, Dec. 22.
