Post-Covid symptoms are caused by aftereffects of the virus due to changes the infection made to cells in your body. Post-Covid changes are not contagious, so if you have a current negative Covid test, it is safe to be around other people. It is wise to be alert for a chance that you are ill again, because it is possible to become infected again.
So you can safely enjoy time with your family - just keep a Covid test handy in case you get symptoms again.
