Lysol in your Nose?!

NPR's Goats and Soda* has another great COVID-19 related poster, titled A Handy Guide to Hand Sanitizers.  

"In your nose?" a questioner asks. NOT!

"Your best bet," according writer Fran Kritz "is the whole combination of protective measures: frequent washing or hand sanitizing your hands, especially if you come in contact with an item or surface that someone else might have touched, physical distancing and wearing a mask. (my emphasis).

The essay about the poster includes tips on using hand sanitizers as well as choosing them. Check the ingredients--wood alcohol- and methanol-based sanitizers are NOT safe. And suppose you are holding a party and wonder about using sanitizing aerosol. They don't work; they are meant to be used on surfaces on surfaces, besides even if they did work their effect is very short, The droplets are regulated by gravity and fall to the floor and other surfaces very quickly.

Lots of good information so for a refresher this one is short and answers typical questions. It also includes a video on SARS-CoV-2 virus behavior in the air.

*And maybe you've wondered about how this NPR program got its name. Playfully and fully answered here; a nice story to boot.
