He has fully recovered but was advised to be in isolation until 3rd December 2021. He will be fit to resume his routine work from 4th December 2021 (sic)." Kamal Haasan appeared on a video call on November 27 and said, "Many people think that Covid-19 has gone or it is just a rumor. But it was a jolt to me when I tested positive. Many, including me, thought that there wouldn't be another wave and got complacent. I can talk to you only because I took two doses of the vaccine. I see this as an opportunity to spread awareness about the virus and request people not to let their guard down. From Chief Minister MK Stalin to many other celebrities, people wished me a speedy recovery. My heartfelt thanks to everyone."
