Reports say that people who jog and ride their bicycles could share and be exposed to the COVID-19 disease via something called slipstream.

Slipstream is a region behind a moving object in which a wake of fluid is moving at velocities comparable to the moving object, relative to the ambient fluid through which the object is moving. People can get sick even if they are practicing social distancing the way that authorities have recommended.

The sad reality is that people are still going outside, despite city, state and national officials telling them to shelter in. And a study confirms that with them exercising in public, they inadvertently spread the coronavirus.


“The droplets that are exhaled by somebody — even if the person coughs or sneezes, but just exhaling is enough,” Bert Blocken, a civil engineering professor at Eindhoven University of Technology in the Netherlands, has explained in his study.

“These droplets are very light,” Blocken added. “They will stay behind in the air and they need time to settle down. If they don’t get the time to settle down, because another person starts running behind you, the other person will simply walk through a dense cloud of droplets.”

This is problematic as so many people are jogging up and down local streets in the community and not on a track.

According to the Philadelphia Inquirer, runners can spew viruses farther than 6 feet, leaving it almost impossible to dodge the virus if someone walks into slipstream in the hood during their exercise.

The study states, “If someone exhales, coughs or sneezes while walking, running or cycling, most of the microdroplets are entrained in the wake or slipstream behind the runner or cyclist.”

That should be more reason to say at home!
