Recent Data on the Effect of Heat and Sunlight on COVID 19

Just this week, William Bryan of the Science and Technology Division of the Department of Homeland Security presented results on the effect of heat and sunlight on COVID 19. The results show that higher temperatures, higher humidity, and especially sunlight dramatically reduce the time that the virus can survive either on surfaces or in the air. On the other hand, typical indoor conditions (70-75 degrees and 20% humidity) are much more favorable for the virus. The takeaway is that being outdoors in summer is a good place to be. Obviously, one needs sunscreen, sunglasses and other protection from the sun. Hopefully, this data will encourage states to open up parks, golf courses, lakes and beaches and other outdoor venues where social distancing can still be maintained.
