It's possible to get COVID-19 twice or more. This is called presymptomatic transmission.
The COVID-19 virus can also spread from someone who is infected but hasn't developed symptoms yet. This is called asymptomatic transmission. The COVID-19 virus can spread from someone who is infected but has no symptoms. The virus can also spread if you touch a surface with the virus on it and then touch your mouth, nose or eyes. Sometimes the COVID-19 virus can spread when a person is exposed to small droplets or aerosols that stay in the air for several minutes or hours - called airborne transmission. These droplets can be inhaled or land in the mouth, nose or eyes of a person nearby. The virus spreads by respiratory droplets released when someone infected with the virus coughs, sneezes, breathes, sings or talks. Data has shown that the COVID-19 virus mainly spreads from person to person among those in close contact.
