Abstract

The surge of the Omicron variant has been studied in overall India, Delhi and Mumbai. The increase in the percentage share of the Omicron strain in total registered cases resulted in a surge of daily new infections. The pathogenicity of Original, Delta, and Omicron variants has been compared using the data collected at the Max Healthcare network in India. The Omicron wave was the least severe of all three waves. The third Omicron wave did not cause much damage due to hybrid immunity generated in the population as a result of vaccination and previous SARS-CoV-2 infection. The low pathogenic nature of the Omicron virus is also the reason for the less severe illnesses the variant caused. Hospitalization during the Omicron wave was just 10% of the Delta wave. The percentage of patients who needed oxygen support was the least during the Omicron wave (23.4%) followed by the Original (63%) and the Delta variant (74%). The less severe nature of the Omicron wave gave the hope of recovering from the deadly devastating COVID-19 pandemic. The symptoms of “long COVID” patients have been compared during all three waves. Nearly the same number of the patients at 5.3% and 5.16% had health issues during Original and Omicron waves, respectively whereas during the Delta surge 5.9% of patients with “long COVID” had symptoms.
