What should i do if i have been in contact with some with covid-19 ?

That depends on.....: What was exposure like? Were you close to infected person – less than 2 meters? Were you both wearing masks? Did the person appear ill? Sneeze or cough near you? Interaction less than 10 minutes? In a crowded or poorly ventilated room? – (vs being outdoors). Even if answer is “no” to many of these questions, a direct cough or sneeze can get infect you.

Contact: You should isolate yourself from others for 10 day and call your physician to arrange testing. If negative and you develop no symptoms after 10 days, you're able to circulate but continue social distancing,wearing mask when appropriate,wash hands frequently. If you develop symptoms report this to your MD and don't circulate until you've done 10 days isolation and have had no symptoms 7 more days
