COVID-19 spreads like other common viruses that cause a cold or the flu—typically via small droplets that spread when an infected person sneezes or coughs.
Being within close proximity to an infected person for a prolonged period (usually within 6 feet for 10 minutes) can put you at a higher risk of infection.
Virus particles can also spread through contact, such as shaking hands or kissing, or they can settle on surfaces such as doorknobs, countertops, and drinking glasses.
