The early news out of South Africa concerning lower hospitalization rates is potentially good (relatively speaking) news. But, as the minister of health in South Africa said, it may be due to vaccine coverage.
About the only thing I know for sure right now is that I don't know for sure how the omicron variant is going to play out.
>>>In the second week of the Omicron wave, between Dec. 9 and Dec. 15, the national data show that the average number of new infections in South Africa was nearly five times greater, at 20,207. Yet, less than 2 percent of these cases have resulted in hospital admissions. Not every case is sequenced, but Omicron is dominant now in the country.
Officials urged caution in interpreting that data. “The mildness of the disease may not necessarily mean that the virus itself is less virulent, but it’s probably also due to significant vaccine coverage,” Dr. Joe Phaahla, the minister of health, said during a televised briefing on Friday. . . .
In previous waves, the proportion of admissions with severe Covid has hovered at 60 percent, Dr. Jassat said, but during this wave, the proportion has dipped below 10 percent nationally. The number of patients needing oxygen is similarly lower.
Five weeks of data from the administrative capital Pretoria and the surrounding municipality show that hospitalizations are lower across all age groups. Among those aged 60 years and older, rates of severe illness appear to be 50 percent lower, compared with the Delta wave. This age group is also the most vaccinated across South Africa, in both rural and urban areas.
“For the first time, there are more nonsevere than severe patients in hospital,” said Dr. Jassat, who leads the hospital admissions surveillance at the institute.
“We have to interpret the less severity data in light of the high seroprevalence and some vaccination coverage,” Dr. Jassat said.<<<
Researchers warned that the epicenter of the country’s outbreak is more highly vaccinated than others, and that natural immunity is also high.
