Answer:
Following physical distancing guidelines and wearing a mask are essential to reduce the risk of infection.
Studies Trusted Source confirm that SARS-CoV-2, the virus that causes COVID-19, spreads from person to person mainly through respiratory droplets created when someone with an infection coughs, sneezes, or talks.
These droplets may land in the mouths or noses of nearby people, or be inhaled into the lungs, where the virus can proliferate.
There are two ways to reduce this risk: physical distancing and wearing a face mask.
