A preliminary study published by South African scientists on November 2 showed that the Omicron variant strain is three times more likely to cause reinfection than the Delta and Beta variant strains.


This finding is based on data collected by the South African health system and is the first epidemiological evidence of Omicron's immunity from previous infections.

As of November 27, of the 2.8 million confirmed cases in South Africa, 356.7 million were re-infection cases.

If a patient’s two positive test results are 90 days apart, they will be considered a reinfected case.

Puliam, director of the South Africa DSI-NRF Epidemiological Modeling and Analysis Center of Excellence, said on Twitter: "The most recent confirmed cases include the primary infections in the three waves. Most of the primary infections occurred in the Delta variant. During the strains raging.”

Puliam emphasized that the study authors did not have vaccination information for the confirmed cases, so they could not assess the extent to which the Omi Keron variant strain evaded the vaccine-induced immune response.

The researchers plan to conduct research in this area next.

South African research papers have been uploaded to the medical preprint server and have not been peer reviewed.
