Study suggests Omicron variant 3 times more infectious than Delta

A new study by South African scientists suggested that the Omicron variant is three times more likely to cause reinfections as compared to the Delta strain.

These findings are based on data collected by South Africa’s health system.

This provides the first epidemiological evidence about Omicron’s ability to evade immunity from prior infection.

The study shows recent reinfections have occurred in individuals whose primary infections occurred across all three waves.

However, the authors did not have information about the individuals’ vaccination status. Hence, it was not clear yet to what extent Omicron evades vaccine-induced immunity.

More data is needed on disease severity associated with the Omicron variant. Earlier, a top South African scientist Anne von Gottberg had forecasted a surge in cases.

But also stressed that the authorities expected vaccines would still be effective against severe outcomes.

Scientists also believe that vaccines will still, however, protect against severe disease.

And it is worth noting that Vaccines have always helped to protect against serious disease. WHO experts are now stressing on calls for a rethink on travel bans against southern Africa.

This comes after the Omicron was reported in more than 20 countries. South Africa and Botswana had detected the Omicron variant.
