How does the coronavirus spread?

The Covid-19 coronavirus outbreak is a new illness and scientists are still assessing how it spreads from person to person, but similar viruses tend to spread via cough and sneeze droplets.

When an infected person coughs or sneezes, they release droplets of saliva or mucus. These droplets can fall on people in the vicinity and can be either directly inhaled or picked up on the hands then transferred when someone touches their face, causing infection. For flu, some hospital guidelines define exposure as being within six feet of an infected person who sneezes or coughs for 10 minutes or longer.

Stay six feet from infected individuals.

  • Viruses can also be spread through droplets landing on surfaces such as seats on buses or trains or desks in school. However, whether this is a main transmission route depends on how long viruses survive on surfaces – this can vary from hours to months.
  • There is anecdotal evidence that the virus can be spread by people before they have symptoms. Some other illnesses such as flu can be passed from one person to another before symptoms occur – but the extent to which this is happening with the Wuhan coronavirus is not well understood yet.

Cover your mouth and nose with a tissue when you cough or sneeze, then throw the tissue in the bin and wash your hands. If you do not have a tissue to hand, cough or sneeze into your elbow rather than your hands.

Face masks offer some protection as they block liquid droplets. However, they do not block smaller aerosol particles that can pass through the material of the mask. The masks also leave the eyes exposed and there is evidence that some viruses can infect a person through the eyes.
