In addition, “a mask may protect you from larger droplets from people around you”.
According to the Centres for Disease Control and Prevention (CDC), recent studies indicate a significant portion of people who have COVID-19 don’t show symptoms, and the virus can spread before they realise they’re sick.
Hygiene matters
“Hand washing is one of the best ways to protect yourself and your family from getting sick,” confirmed the CDC.
Wash your hands with soap and water after returning home from a public place, where you’ve touched shopping carts, electronic cashier screens or door handles.
