COVID-19 is primarily spread through social interaction. If a healthy person comes face to face with an infected person, they may contract the virus through contaminated droplets spread by coughing or sneezing. Your hands can be a major source of infection: the tiny droplets that hang in the air after a cough or sneeze may settle on surfaces such as counter tops, tables or even door handles, contaminating them. If you touch your face after touching these surfaces you may also contract the virus.
