1/ Some #SaturdayMorning #SaturdayThoughts on masks. 
Most people still don’t understand the term and concept of “asymptomatic spread” of #covid19, and why we now recommend that everyone who can, wear a mask as a way to facilitate safee reopening. See thread
for more info.

2/ The coronavirus currently causing our global pandemic- SARS COV2, is actually from a family of viruses, including SARs, MERs, & the common cold.
For those other related viruses, it’s very rare for a person who doesn’t feel sick, or look sick, to be able to spread disease.

3/ Put another way, most people spreading the common cold for instance, have symptoms - like a fever, a runny nose, or a cough.
And when you have such symptoms or come across someone who does, you know to keep your distance in order to prevent the spread of those germs.

4/ In the case of this new virus that causes #COVID19, around half of the people who have it actually feel and look fine. 
They have NO symptoms or are “asymptomatic.”
You won’t know that you or someone standing next to you has the virus, and is capable of spreading it.

5/ Once scientists realized this new #coronavirus behaved differently than anything we'd seen before, recommendations on masks changed. 
Current research/ data now tells us
of the most effective ways to prevent #COVID19 spread is for as many people as possible to wear masks!

6/6 Scientists and health officials give the best advice they can based on available info- but when the data changes, so too must the advice.
The high degree of asymptomatic spread of #COVID19 is why we all should embrace wearing as part of a safe & sustained reopening.
