I have been in contact with a person who had tested positive for covid 19, do i need a referral letter to do the test?

Contact your Dr.: 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.
