Starting mid-March 2021, India has become the epicenter of COVID-19 as a second wave of infections devastated the country. India reported 50 percent of global cases and 30 percent of global COVID-19 deaths, and an alarming rate of over 400,000 daily new cases at the height of the wave in early May 2021.

Multiple COVID-19 genetic variants have been detected since the initial SARS-CoV-2 strain was found in China, the most significant of which are classified by the WHO as variants of concern or variants of interest, depending on their attributes and risk level.
