Omicron variant more likely to be re-infected than Delta: study


Cape Town: A team of researchers in South Africa said they found some evidence that people who were once infected with Kovid are more likely to be re-infected with the Omicron variant than the beta or delta variants.

According to a report by CNN, the research team said that it is too early to say anything about this for sure, but the recent increase in infections for the second time has indicated to them that people in Omicron have been re-infected. more likely to do.

“Contrary to our expectations and experience with the previous variant, we are now experiencing an increased risk of reinfection, which exceeds our previous experience,” said Juliet Pulliam of Stellenbosch University.

Omicron was identified as recently as November, but it has alarmed the World Health Organization (WHO) and other global health officials, who have described it as dangerous because of its many mutants. It is being told that it is more infectious than other variants, as well as it has the ability to evade the immune system. Doubts are being raised about this that even the dose of the vaccine is not going to have any significant effect on it. However, many experts are not convinced and say that the vaccine will definitely provide some protection against any variant.

The new variant has been described as a Variant of Concern.

Pulliam and his colleagues have looked at reports of infections covering 2.7 million people in South Africa since the start of the pandemic, with more than 35,000 people infected with more than one covid-19 infection.

Of the 27 lakh people who tested positive, 35,670 suspects were found to be re-infected.

In their report posted online in a preprint, the researchers said, we have identified 35,670 suspected cases of being infected at least twice (as of November 27, 2021), three infections in 332 individuals and four suspected cases in one person. The infection has been confirmed.

Of the individuals who have had more than one reinfection, 47 (14.2 per cent) experienced their third infection in November 2021, which suggests that many third infection cases are linked to the Omicron variant, he said.

They are assuming that the recent spurt in cases in South Africa reflects Omicron’s spread, not some other factor such as weakened immunity.

The virus in those whose cases they describe has not been sequenced or sequenced, so it is not certain whether they were actually infected with the Omicron variant.

However, officials have said the Omicron variant is now the dominant coronavirus strain in South Africa, accounting for 74 percent of genetically sequenced samples in November. More number of sequencing is underway to determine the true prevalence of the variant.
