How does the virus spread?

The virus that causes COVID-19 seems to be spreading easily and sustainably in the community (“community spread”) in some affected geographic areas. Community spread means people have been infected with the virus in an area, including some who are no sure how or where they became infected.

Like other respiratory illnesses, such as influenza, human coronaviruses most commonly spread to others from an infected person who has symptoms through:

  • Droplets produced through coughing and sneezing.
  • Close personal contact, such as caring for an infected person.
  • Touching an object or surface with the virus on it, then touching your mouth, nose, or eyes before washing your hands.

Do not assume that someone of a race or nationality is likely to have COVID-19; this virus has infected people of many different races and nationalities across the entire world.
