Of course, it is true that masks don’t work perfectly, don’t replace hand-washing and social distancing, and work better if they fit properly. And, of course, surgical masks (the disposable type that surgeons wear) don’t filter out small viral particles like medical-grade respirator masks rated N95 and above. However, surgical masks protect a bit more than not wearing masks at all. We know from flu research that mask-wearing can help decrease transmission rates along with frequent hand-washing and social distancing.
When to Use a Mask?
The World Health Organization recommends using face masks in these cases:
- If you are healthy, you only need to wear a mask if you care for a person with a suspected 2019-nCoV infection.
- Wear a mask if you are coughing or sneezing.
- Masks are effective only when combined with frequent hand-cleaning with alcohol-based hand rub or soap and water.
- If you wear a mask, you must know how to use and dispose of it properly.
