According the Centers for Disease Control and Prevention (CDC), COVID-19 is thought to spread mainly by respiratory droplets released when people talk, cough, or sneeze. Many cases are asymptomatic, meaning that do not show any symptoms but can still spread the virus to others.
Wearing a face covering will help limit the number of droplets that are released and limit how far they travel. This will help protect the people around you if you are infected or do not know you are infected. Face coverings along with other measures like washing your hands frequently and social distancing work together to prevent the spread of this disease.
