write a report on mask used in covid
Answers
Masks are a key measure to suppress transmission and save lives.
Masks should be used as part of a comprehensive ‘Do it all!’ approach including physical distancing, avoiding crowded, closed and close-contact settings, good ventilation, cleaning hands, covering sneezes and coughs, and more.
Depending on the type, masks can be used for either protection of healthy persons or to prevent onward transmission.
Even when you’re in an area of COVID-19 transmission, masks should not be worn during vigorous physical activity because of the risk of reducing your breathing capacity. No matter how intensely you exercise, keep at least 1 metre away from others, and if you’re indoors, make sure there is adequate ventilation.

Masks are a simple barrier to help prevent your respiratory droplets from reaching others. Studies show that masks reduce the spray of droplets when worn over the nose and mouth. You should wear a mask, even if you do not feel sick.
