Scientists Studying Omicron See Rise in Reinfections

“Scientists in South Africa tracking the spread of the Omicron variant said Thursday they are seeing a rise in reinfections in people who had recovered from Covid-19 as the country reported another sharp daily rise in new cases,” the Wall Street Journal reports.

“The scientists’ conclusions suggest previous infection provides less protection against the new variant than against earlier versions. They also offer a possible explanation of why Omicron has been able to spread so quickly in the country, outpacing even the highly transmissible Delta variant, which is currently dominant in much of the rest of the world.”
