Stop in for a cup of coffee

I know a guy who had Covid and was in very bad shape....was able to get passed most of it while hospitalized. He is home now and says he has double (each lung) pneumonia.....um, wait.....does Covid cause pneumonia? or was that the issue all along??? Haven't heard of a single pneumonia case this year and people used to die from that all the time. I am an asthmatic, I pay attention to those things when you hear of it going around.
