How deadly is Omicron’s new variant BA.2 compared to Delta? Big claim in research

Washington. Researchers in the US have claimed that the BA.2 form of Omicron is far less lethal than the delta form of the corona virus that wreaked havoc during the Kovid epidemic. According to a research team led by investigators at Massachusetts General Hospital in the US, Omicron’s BA.2 has less firepower than the original Omicron form. The researchers found that from March 3, 2020 to June 20 this year, out of 1,02,315 confirmed COVID-19 cases in the US, 20,770 cases were of the delta form, 52,605 of the true form of Omicron B.1.1. There were 28,940 cases.

The mortality rate was 0.7 percent for Delta, 0.4 percent for the original Omicron format, and 0.3 percent for Omicron BA.2. The Delta and the original Omicron versions were twice as likely to die compared to the Omicron BA.2, the researchers said. The study is published in the ‘Journal of the American Medical Association (JAMA) Network Open’. According to the findings of the study, the severity of SARS-CoV-2 may be reduced.
