  • As the weather warms up, this is what we typically see--people out enjoying it.

  • Turns out that’s one of three reasons scientists expect to see the spread of COVID-19 to slow down the summer.

  • Probably the most important one is crowding.

  • So in the winter people are inside more.

  • Since they are inside more, they are closer.

  • When people are outside, higher temperatures break down the virus on surfaces and in the air faster so it becomes less infectious.

  • Same with higher humidity.

  • The virus can’t survive as long when it is humid.

  • Scientists took that information about the way heat affects our behavior and the virus and tracked the spread of COVID-19 all around the globe.

  • They found the transmission was fastest in the areas that were cool and dry, up to about 62 degrees.

  • And then they mapped out their predictions.

  • By rate summer, Sacramento county could see just under two people infected by every new case of the virus, down from 2.3 right now.

  • That means it is still spreading, just not as fast.

  • The numbers are much more dramatic in areas with more extreme weather, like Phoenix, Arizona, weather rate of transmission could drop 40% this summer.

  • But two points to keep in mind.

  • In every map, the virus bounces back in the fall.

  • And while the weather can slow the virus, it won't stop it.

  • It would have to be unbearably hot for covid to be wiped out.

  • It would have to be over 130 or 160 degrees or something like that to really ... to really get rid of it.

  • But the higher the temperature, the less it survives.

  • And that means the bottom line is that we can't depend on the weather to keep us safe from COVID-19.

  • I think I know the answer to this question, but does that mean we can let down our guard?

  • No, we can't let down our guard.

  • It is really important to maintain the social distancing.

  • That is the number one thing we can do during this time when we don't have a vaccine.

  • And Dr. Blumberg estimates that right now about 4 percent of us have been infected with COVID-19 here in California.

  • So that means the vast majority of us are still susceptible.

  • And Lisa and Gulstan, that means we still need to be careful.

  • Yes, very good reminder and great explanation, alright Edie, thank you so much.
