Thanks

I wonder if the fact that Tennessee has two very large cities is impacting this. Grew up in that area of the country, and Kentucky has lower population density by far. Not questioning the value of these lockdowns, just curious what impacts the greater urbanization of TN would have?
Pay no attention to those morons saying “let people die.” They are a small, loud minority.

This is a Nice Global Hackathon if someone is interested.

Mask is a must!

Masks will safe your life and of your dear family!

In Cambodia, if you don’t wear a mask many people will feel offended that you do not respect their health. Especially if you are a Westerner right now…

Suggestion: Could these slides be put up as a series of tweets explaining the advantages of using masks to help reduce transmission? Might help convey the message better than sharing the video link…

Jeremy just advised to check mask fit by verifying it’s making it impossible to smell something with a strong odor. Beware asnomia (loss of smell) is a possible Covid-19 symptom, so do check you’re able to smell without the mask before you perform this test.

Thank you so much for continuing to perform this service during this horrific time. We all appreciate it, so much.

A famous actor from India: Shah Rukh Khan (SRK) also made a fun(ny) video spreading awareness about the virus . He too has mentioned the important of masks towards the end.
