There are three cases of of covid-19 where i'm staying can i test even though i'm not symptomatic. i m concern that that i might have contracted the infection?

ZA or USA?: I can’t tell where you are from. If from South Africa, contact PCM who will assess & make determination about COVID 19 testing. If asymptomatic they might have you just quarantine. USA – policies vary by state. State & local health departments/ providers make actual testing decisions. Some states require a dr.'s referral & some don't. Can call PCM if one believes they should be tested.
