How Does COVID-19 Spread?

This virus was first detected in Wuhan City, Hubei Province, China, the CDC said. The first infections were linked to a live animal market, now the virus is spreading from person to person.

"The virus that causes COVID-19 seems to be spreading easily and sustainably in the community (“community spread”) in some affected geographic areas," the CDC said.

Community spread means people have been infected with the virus in an area, including some who aren't sure how or where they became infected.

Prevention, Symptoms and Treatment of COVID-19

There's currently no vaccine to prevent COVID-19. The best way to prevent illness is to avoid being exposed to this virus. The CDC recommends preventive actions every day to help prevent the spread of respiratory diseases, including:

  • Avoid close contact with people who are sick.
  • Avoid touching your eyes, nose and mouth.
  • Stay home when you're sick.
  • Cover your cough or sneeze with a tissue, then throw the tissue away.
  • Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.
  • Follow CDC’s recommendations for using a facemask.
  • Wash your hands often with soap and water for at least 20 seconds, especially after going to the bathroom, before eating and after blowing your nose, coughing, or sneezing.
  • If soap and water aren't available, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty.

The CDC doesn't recommend that people who are well wear a facemask to protect themselves from respiratory diseases, including COVID-19.

Facemasks should be used by people who show symptoms of COVID-19 to help prevent the spread of the disease to others. The use of facemasks is also crucial for health workers and people who are taking care of someone in close settings.

Reported illnesses have ranged from mild symptoms to severe illness and death for COVID-19 cases, the CDC said. Symptoms may appear two to 14 days after exposure to the virus and include fever, cough and shortness of breath.

There's no specific treatment recommended for COVID-19. People with COVID-19 should get care to help relieve symptoms. For severe cases, treatment should include care to support vital organ functions, the CDC said.

People who think they may have been exposed to COVID-19 should contact their healthcare provider immediately.
