Experts suggest Omicron sub-variants are to responsible for Delhi's 4.5-month peak in Covid cases.

Delhi daily count of Covid-19 in Delhi at highest level in nearly four and a half months . Gurgaon reported 497 new Covid cases, up 78% from previous day .

NEW DELHI (New Delhi) – On Thursday, the daily count of Covid-19 in Delhi stood at 1,934, the highest level in nearly four and a half months.It's also a big jump from Wednesday's 928 cases.According to statistics shared by the state health department, 23,870 tests were performed in the last 24 hours relative to 13,099 the day before.This could explain the sudden rise in cases.

The optimism rate stood at 8.1% on Thursday, up from Wednesday's 7.8%.Covid-19 cases are on the rise in India, too.However, the amount of hospitalization is lower than in the previous waves.On Thursday, Gurgaon revealed 497 new Covid cases, up 78% from the previous day, when it reported 278 cases.

When Omicron was first detected in India, the sub-variants in circulation were BA.1 and BA.2.However, BA.4 and BA.5 are now being confirmed.As long as hospitalizations are minimal, we shouldn't be concerned about localized spikes, he said.According to a new analysis by scientists from Beth Israel Deaconess Medical Center in the United States, where Covid-19 cases have been on the rise in recent weeks despite widespread vaccination and exposure to the virus, the newer sub-variants of Omicron were able to escape immunity offered by both natural infection and vaccination.

According to a study published in the New England Journal of Medicine, BA.2.12.1, BA.4, and BA.5 sub-variants miraculously escaped neutralizing antibodies induced by vaccination and infection.In addition, neutralizing antibody titers against the BA.4 or BA.5 sub-variants and (to a lesser extent) against the BA.2.12.1 sub-variant were lower than titers against the BA.1 and BA.2 sub-variants, indicating that Omicron has continued to evolve with increasing neutralization escape, according to the study.
