Masks, DIY Masks, and COVID-19

This is the second part of AAQB's COVID-19 resource series, where we provide information and resources to the community, and today, we'll be talking about masks!
For people who have to go to high-risk areas, it's important to have some protection from infection, and the best way to do that is with a mask.
The best and most effective type of mask is an N95 mask. However, these masks are highly specialized equipment and almost impossible to find nowadays.
So what are the alternatives?
Many people are using surgical masks, but these are NOT effective in preventing infection. They help prevent the spread of the virus if the wearer is infected, but they don't help a healthy person stay uninfected.
However, you can make a mask at home.
What you need is a piece of thick fabric  or multilayered gauze that you can fit over your mouth and nose, and two pieces of elastic or string.
Attach the elastic or string to the fabric at the top and bottom to make anchors. It's crucial that those pieces of material fit very tightly and snug on your face, as that's what's protecting from the virus.
​Once you're done, it should look something like this:

It's important to wash your new mask frequently.
Stay home and stay safe, everyone!
