Excuse me but nobody is even asking which parish of the Russian Orthodox is in her neighborhood. The closest priest and his wife and the church women's group there is there just for that reason.

I'm a covid nurse in the states... If she is really sick with it as in having shortness of breath, breathing fast >20 per min or a low heartbeat <60 please take her into the hospital. Otherwise there should be home health services that can go to her house and check up on her. But if she's experiencing mild symptoms try not to have anyone go see her if it's not absolutely necessary.
