So i had a call from a friend saying he heard i was on quarantine because i had visited a retail business and the owner has now been tested positive. should i quarantine? covid-19?

Yes: Self isolate for at least 14 days or three days without fever, whichever is longer. If there are symptoms, such as congestion, cough, shortness of breath, testing is advised. For test sites, please check your local listings.

Closeness of contact: 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? – Even if answer is “no” to many of these questions, a direct cough or sneeze can get infect you.
