Answer 1

Answer:

The 2019–20 coronavirus pandemic is an ongoing pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID-19 is caused by infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus strain. Although for most people COVID-19 causes only mild illness, it can make some people very ill. More rarely, the disease can be fatal. Older people, and those with pre- existing medical conditions (such as high blood pressure, heart problems or diabetes) appear to be more vulnerable.

Answer 2

Answer:

Here are the basics of how to wear a mask:

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.
