What about face mask?
When COVID-19 started to spread throughout the world, expert did not recommend the usage of face mask as a means of protection for the majority. The main reason for doing so was because if healthy people buy a lot of medical masks, it will be insufficient for the doctors and nurses who need the most as they will be directly attending to the patients with COVID.
Washing your hands often and practicing social distancing are still the best ways to protect yourself and others. And experts still do not recommend that people who are not health workers wear a medical mask.
Recently, The Centers for Disease Control and Prevention (CDC) does now recommend covering your face when you need to leave your house. This is mostly so that if you are sick, even if you don't have any symptoms, you are less likely to spread the infection to other people. You can use cloth or a bandana to cover your mouth and nose. There are instructions online about how to make your own mask using fabric and rubber bands.
Even if you cover your face, it's still important to stay home except when you need to go out to purchase food, medicine or other basic needs. And be sure to stay at least 6 feet away from other people even when you do leave your home.
When you take your face cover off or the mask, make sure not to touch your eyes, nose, or mouth. And wash your hands after you touch the face cover. You can wash the face cover with the rest of your laundry.
