In a recent video, 92-year-old former Los Angeles Dodgers manager Tommy Lasorda decked out in Dodger blue and wearing a face mask and gloves, made a public service announcement urging folks to stay at home.

"Stay Home! Wear your mask!" he said. "Do everything to help yourself, and your country, and your friends."

It was a heartfelt message but, as viewers pointed out, he was not wearing his mask correctly. The World Health Organization (WHO) says that masks should cover your mouth and nose even though it might feel awkward.

The Centers for Disease Control and Prevention (CDC) offers these guidelines for the correct use of a facemask to protect your against COVID-19, according to the Los Angeles Times:

• It must fit snugly but comfortably against the side of your face.
• It should be secured with ties or ear loops.
• It must have multiple layers of fabric to be effective.
• You should be able to breathe freely.
• The mask should be washable and machine dried without damage or losing its shape.
• It must cover both your nose and mouth with no gaps between your face and the mask.

Be careful not to touch your eyes, nose or mouth when removing the face mask and wash your hands immediately after removing it, according to the CDC. WHO recommends cleaning your hands with an alcohol-based hand rub or soap and water before donning the mask and replacing the mask with a new one as soon as it is damp, according to the Times. The agency also warns NOT to touch the front of the mask when you remove it.

Paula Cannon, a professor of molecular microbiology and immunology at the Keck School of Medicine at UCS, says an interview with the Times, that while there are multiple guidelines online on how to obtain or make your own face mask, it should be comfortable and let you breathe easily.

"Because if you can't breathe easily, or it gets wet or uncomfortable, you're going to be fiddling with it, and you're going to be doing the very thing we want the mask to stop you from doing, which is touching your face," she says.

Here is a T-shirt design she recommends.
