Abstract

Background: COVID-19, the pandemic caused by the SARS-CoV-2, is a global health calamity and one of the greatest challenges faced by the humankind across the globe. The virus originated in Wuhan, China and spread rapidly to more than 200 countries/nations, affected more than 600 billion individuals and caused around 65 lakh deaths worldwide. Since the start of the pandemic, SARS-CoV-2 mutates and accumulates genetic variations which constantly resulted in the emergence of new variants.

Objective: The current article discusses about the new omicron sub variant BF.7, and how this BF.7 variant may pose risk in India, if it overrides the current COVID-19 circulating variants.

Content: The emergence and potential consequences of the circulating SARS-CoV-2 variants usually augment virus transmissibility and host immune evasion. The current spurt in COVID-19 infections in China which has alarmed people around the world, is believed to be driven by an omicron sub variant BF.7. Although India has been reporting a "steady decline" in COVID-19 cases, we need constant surveillance to keep a track of the new emerging variants in circulation. Keeping in mind, the new surge in COVID-19 cases across many nations, we discuss about the new variant and its possible impact on India.

Keywords: BF.7; COVID-19; Omicron; SARS-CoV-2.
