Black People are the Most Affected by COVID-19
Covering your mouth and nose in public spaces, especially indoors, is an easy way to show respect for other people as well as to help slow the spread of COVID-19. Masks of all sorts help for this. Bandanas, neck gators, cloth masks, and things I probably never would have thought about will help keep all of our droplets to ourselves.
If you have questions about COVID-19, please check out the Centers for Disease Control (CDC) website.
UPDATE June 11, 2020:
More studies have been done. WEAR A MASK. Here's an article from Reuters that explains why.
Back to original article:
Wired Magazine (yes, I'm a nerd) has an easily digestible article about Black people being the most affected by COVID-19 in both infection rate and death rate. If you prefer cold, hard facts, check out this link at the CDC.
What do I have to say about any of this? I'm just trying to be useful. I see varying levels of mask wearing happening at the protests I'm watching. If the data says wearing masks will help, I'm gonna put on a mask and point to the data. So, whether you're protesting or grocery shopping, please consider masking up. You just might save someone's life.
