Hi, we had groceries delivered today. And the delivery man coughed once.. we aren't sure whether he was wearing a mask. After the man left, I went to collect the box.. I was wearing a glove and mask but I think my mask was a bit loose around the nose and I could breathe as normal.. is there a chance of me getting covid due to breathing the air in case that person was infected ?? The Hallway is open on both sides..I am very scared now and I have washed my hands multiple times thereafter... please help

Please find the attached report of back of neck says a small inflamatory lession since observed from last 10 months but no other symptoms in bodies like fever , weight loss , other swelling etc. The existing swelling is painless, not increased. My physician says to do further FANAC to get confirm, but due to COVID situations I am unable to perform FANAC . What is your opinion as per USG is anything wrong? . Regular physical exercise can be continued pls explain?
