Why do we need face coverings?
At first, scientific research on the benefits of wearing face coverings suggested they weren’t especially useful. But in June, as new studies were published, the World Health Organization (WHO) changed its advice. They said: “In light of evolving evidence, the WHO advises that governments should encourage the general public to wear masks where there is widespread transmission and physical distancing is difficult.”
COVID-19 spreads when droplets from an infected person’s mouth or nose spray into the air and land on surfaces when they talk, sing, cough or sneeze. Many people who are infected with the virus don’t know they are, because they have no symptoms or haven’t yet started feeling poorly. So by wearing a face covering in enclosed spaces, we protect others from breathing in or touching our droplets.
