Wife got sick recently. Doctor said she had pneumonia. Congestion and coughing, but wasn't too bad. Into the 3rd day, I got sick too. Coughing wasn't too bad, but the congestion was constant for approx 8 days. I'm just glad I didn't have fever, nor needed to visit a doctor. Next time, I'm sleeping on the couch and might wear a mask if I'm anywhere near her. :-)
