If COVID-19 is spreading in your community, stay safe by taking some simple precautions, such as physical distancing, wearing a mask, keeping rooms well ventilated, avoiding crowds, cleaning your hands, and coughing into a bent elbow or tissue. Check local advice where you live and work. Do it all! You also find out more about WHO's recommendations for getting vaccinated on our public advice page on COVID-19 vaccines.
Clean your hands before you put your mask on, as well as before and after you take it off, and after you touch it at any time.
Make sure it covers both your nose, mouth and chin.
When you take off a mask, store it in a clean plastic bag, and every day either wash it if it’s a fabric mask, or dispose of a medical mask in a trash bin.
Don’t use masks with valves.
For specifics on what type of mask to wear and when, read our Q&A and watch our videos. There is also a Q&A focused on masks and children.
