Md. Gov. Larry Hogan issues ‘stay at home’ order
It will be interesting to see if keeping people indoors really helps at all. I personally hope that they don't put this into effect in VA.
https://www.mercurynews.com/2020/03/27/coronavirus-q-a-part-3-is-hiking-ok-is-my-newspaper-infected-what-about-sex/Q: How do I limit my exposure while hiking outside? When passing people heading in the opposite direction on a narrow trail, is there a risk of contracting the virus from the air, or in the air on the trail that they came from? What keeps me from from picking up their viral spray?
A: Outdoors on the trail, where there’s a breeze, the virus will probably be quickly killed by ultraviolet light from the sunlight. If a person is coughing and passes closely, it’s potentially possible that the virus could be transmitted. But the risk is exceedingly small.
In still air, the virus can remain suspended for up to about three hours. So if you walk into a room after somebody has been coughing, it’s possible that you can get infected droplets that are suspended in the air. But outdoors, I think it’s highly unlikely.
In hospitals, we consider a risk of substantial exposure somebody who has been within six feet for four minutes.
