COVID-19 spreads through droplets or aerosols released when an infected person talks, coughs, sneezes, sings or shouts.
These infectious droplets or aerosols can easily spread to others when they are inhaled or reach the nose, mouth or eyes of people in poorly ventilated spaces or in close contact. The virus can also spread when a person touches another person (i.e. a handshake) or a surface or object that has the virus on it and then touches their mouth, nose or eyes with unwashed hands. The virus can be spread to others from someone who is infected but is not showing symptoms (either because they haven’t yet developed symptoms or are asymptomatic).
