Coronaviruses are important human and animal pathogens. At the end of 2019, a novel coronavirus was identified as the cause of a cluster of pneumonia cases in Wuhan, a city in the Hubei Province of China. It rapidly spread, leading to a global pandemic. In February 2020, the World Health Organization designated the disease COVID – 19, which stands for coronavirus disease 2019.. The virus that causes COVID – 19 is designated as severe acute respiratory syndrome coronavirus 2 ( SARS–CoV–2 ). Like other viruses, SARS-CoV-2 evolves over time. Certain variants have garnered widespread attention because of their rapid emergence within populations and evidence for transmission or clinical implications; these are considered variants of concern. The Omicron variant ( B.1.1.529 ) was first reported from Botswana and very soon thereafter from South Africa in November 2021. It was promptly identified in multiple other countries, where it was associated with sharp increases in reported infections. The Omicron has a replication advantage and evades infection and vaccine induced immunity to a greater extent than prior variants. It appears to be associated with less severe disease than other variants. The Delta ( B.1.617.2 ) lineage was first identified in India in December 2020 and had since been the most prevalent variant worldwide until emergence of the Omicron variant. It was more transmissible, and was associated with a higher risk of severe disease and hospitalization.COVID19 Specialist Doctor In Mumbai.
