The advisory added that samples from covid clusters must now be sent to India’s genome sequencing laboratories, while emergency operation centers set up during the second wave should be reopened. On the same day that the advisory was issued, more than 200,000 women attended an event on women’s empowerment where Narendra Modi spoke, according to the Prime Minister’s office.With five states heading to the polls in 2022, political parties have been holding rallies with hundreds of thousands in attendance. Although Modi has not held election rallies in Uttar Pradesh, a critical state in the upcoming elections, he has been addressing large gatherings in the state for various policy announcements and inaugurations.Following India’s second covid wave that peaked during the months of April and May, restrictions on gatherings, travel and entertainment have been lifted by state governments over the recent months. While the central government had imposed a nationwide lockdown in March 2020, they have since issued guidelines and advisories to state governments, leaving them to decide on local containment measures depending on their specific covid situation. At least 200 cases of Omicron have been detected in India since December 2 and a total of 34,758,481 covid cases have been recorded in the country as of Wednesday, including 478,325 deaths, according to the health ministry.
