Abstract

The dynamics of the Omicron variant in India, Mumbai, and Delhi have been studied. The % share of the Omicron variant in overall India rose from 0.35% to 97.12% during the period November 29, 2021, to February 7, 2022. Due to the emergence of the Omicron variant, the daily new infections in India rose from a baseline tally of below 8,000 cases to the highest number of 347,063 cases recorded on January 20, 2022. In Mumbai, the Omicron variant completely replaced the Delta and other lineages as reported on March 3, 2022 genome sequencing report. In Mumbai because of the Omicron variant surge, the new infections rose to 20,971 on January 7, 2022, from a baseline tally of 191 daily cases recorded after receding the second Delta variant wave. In real-time, the vaccine effectiveness among the Indian population during the Omicron variant surge was studied and noticed that the two-dose regimen was 99.3% effective in preventing death. The death rate among the hospitalized patients was reduced by 12% among the vaccinated individuals compared to the unvaccinated ones. During the Omicron variant wave, the average age of the COVID-19 patients shifted by 11 years towards the younger age which was because the vaccination among the younger population was low compared to the elderly population.
