The evil thing about SARS-CoV-2 is that you can transmit the disease before you even really show any symptoms. I had been social distancing like a pro, and only visited my mother once. Two days after the visit she has a slight cough, gets tested and is confirmed positive. I immediately isolate myself, also develop a cough the next day, get tested two days later, also positive. No other contacts so I'm 90% positive I got it from her, even though she was perfectly healthy on the day of my visit.
So don't just stay away from people that are confirmed to have it (that one is a given anyway), but stay away from people in general, within reason. You never know. Stay safe!
