According to a South African study, the risk of re-infection with the new Omicron variant of the Coronavirus is three times higher than with its delta or beta variant.
Researchers published this study on Thursday. This study is based on data collected by the South African Health System. Using the Omicron variant at the infection level, this is the first research of its kind that shows how well the new variant penetrates immunity. The research paper has just been uploaded to the medical preprint server, and it has not yet been peer-reviewed.
In the research paper, out of 2.8 million (28 lakh) cases in South Africa, 35,670 cases are likely to recur. These figures were taken on November 27. It is considered re-infection if a person becomes positive after a gap of 90 days. Juliette Pulliem, director of the DSI-NRF Center of Excellence in Epidemiological Modeling and Analysis in South Africa, tweeted, “Recent cases of re-infection in people found infected in the last three waves of Corona have gone. The majority of these were infected with the delta variant.
What is the effect of Omicron on immunity?
Although Pulliam cautioned the researchers to not give out personal information, it did not stipulate how much damage Omicron caused to the immunity created by the vaccine. Researchers plan to investigate this further.
Pulliam said, “The data is needed to establish the severity of the disease. Exclusively associated with Omicron. It should also contain information about people who have previously been infected. Michael Head of the University of Southampton has praised the research, calling it of high quality.
According to his statement, “This analysis is concerning. Due to the previous infection, the new variant is easily penetrating the immunity. It seems highly unlikely, but it may be wrong.’ Consequently, expert and scientist Anne von Gottberg of South Africa’s National Institute for Communicable Diseases warned that cases of infection have increased rapidly, but there is still hope that the vaccine will still be effective.
Do you still not know where Omicron came from?
At a news conference of the South African branch of WHO, Gottberg said, “We believe there has been an increase in cases of infection in all parts of the country. At a news conference of the South African branch of WHO, Gottberg said, “We believe there has been an increase in cases of infection in all parts of the country. Our opinion is that the vaccine will be effective against the severity of the disease and protect people. According to him, the vaccine has always been effective against serious illnesses, hospitalizations, and even death. In the meantime, WHO experts have urged countries to reconsider the ban on travel to South African countries. The WHO reports that a new variant of Coronavirus has been found in at least two dozen countries without having been identified from where it originated.
WHO expert Ambrose Talisuna said, “Botswana and South Africa have identified the variant.” The origin of this variant is unknown. There is no reason to ban people who have identified and reported the variant in such a situation.
According to official statistics from mid-November, 300 cases of Corona infection are arriving every day in South Africa, and 8,561 cases were registered in the country on Wednesday, which was 4373 more cases than the day before and on Monday. Their number was 2,273 more than that.
