Fact check: You can safely ignore that “HOW TO FIGHT COVID AT HOME” meme

I noticed this meme a few days ago. I recognized the “friend of a friend who has insider knowledge” formula that makes people want to share a memes. I know better than to trust anonymous online sources that claim to have special knowledge, so I just re-read what the CDC says and moved on.

The bar-hoppers and close-talkers and eaters-in-crowded-diners are right when they say social distancing alone won’t stop the spread of a pandemic.
