Why you’re unlikely to get the coronavirus from runners or cyclists
“The good news is that we do know that while the virus can persist in the environment on different surfaces and in different environments, it does lose infectivity over time,” Rasmussen said. “So if you inhale a large number of total [virus particles] but only a small number of them are infectious, you are at much lower risk of actually getting infected.”
None of this is to say you should be cavalier when you venture into the outside world. Washing your hands, avoiding touching your face, being diligent about physical distancing, wearing masks in public, and disinfecting communal surfaces — all these things likely reduce transmission risk, and we should keep doing them, Rasmussen said. But she also said she feels fine about taking a walk with her husband outdoors.
Psychologically, different people have different levels of tolerance for risk. For some people, any risk that can be minimized, should be, no matter how small. For others, the recommended 6-foot distance, with masks, and the known decay of both the amount and the infectiousness of the virus — that’s good enough.
