There was a worker who visted our house , i was about 10 feet away from him . so i wasnt wearing mask. i read on internet that covid survives in air , can i get it in the air now ? i am very anxious now

COVID 19: The SARS -CoV-2 virus only lives in the air for a brief time (some estimate 3 hours). I would wear a max even if you are ten feet away because a vigorous sneeze or cough can actually travel a good distance if the person isn't wearing a mask. In general there is more risk when in crowded, tight, poorly ventilated rooms - outdoors is considered safer.
