Sure enough, a few hours later, a contact tracer called to deliver the bad news: I’d tested positive. “If you layer [testing] with masking, and then physical distancing, then you create a strategy where together it significantly reduces the chance of transmission.”, Plenty of others disagree. But given the way COVID-19 is believed to be transmitted, lingering on surfaces and in the air, it would be “very difficult” for anyone to prove that a particular person caused them to become ill, Ahmed says. How long it takes to get the results of a COVID-19 test varies.
