Welcome @mishra1423, Sorry to hear you came down with Covid at the same time your PMR is active. I'm not a doctor but think you can get Covid with or without a suppressed immune system. Being you have Covid now, I think the standard practice is to self isolate along with other precautions to avoid passing Covid onto anyone else.

Do you have family or friends that can help or provide support for you while you have Covid?
