The study looked at data that were available by the end of November. They “strongly indicated a lesser severity of the omicron wave of infection,” said Cheryl Cohen of South Africa’s National Institute for Communicable Diseases (NICD).
Cohen added, however, that the data are still early and that more studies are needed. According to previous findings, vaccinated Omikron patients would have a 70 percent chance of avoiding treatment in the intensive care unit.
In South Africa, the Omikron variant already dominates the infection process. The greater area around the metropolis of Johannesburg and the capital Pretoria had at times had a share of up to 80 percent of the daily new infections nationwide.
However, the number of hospital admissions is well below that of previous waves of infection. The number of stays in the hospital also fell significantly to an average of three to four days, according to the study.
