Is anyone sick or know anyone

We have one friend who seems to be symptomatic. Told us she was out shopping.(Idiot)
And that's why we have chosen to self isolate.Both Me and My gf had pneumonia within the last 10 years . That was rough I don't know if My lungs could handle anything like that again.Had a ct scan a few weeks ago and seems my lungs may have some scar tissue.
