What is coronavirus disease 2019


Coronavirus disease 2019 (COVID-19) is a respiratory illness that can spread from person to person. The virus that causes COVID-19 is a novel coronavirus that was first identified during an investigation into an outbreak in Wuhan, China.

Can people in the U.S. get COVID-19?

COVID-19 is spreading from person to person in China, and limited spread among close contacts has been detected in some countries outside China, including the United States. At this time, however, this virus is NOT currently spreading in communities in the United States. Right now, the greatest risk of infection is for people in China or people who have traveled to China. Risk of infection is dependent on exposure. Close contacts of people who are infected are at greater risk of exposure, for example health care workers and close contacts of people who are infected with the virus that causes COVID-19. CDC continues to closely monitor the situation.

How does COVID-19 spread?

The virus that causes COVID-19 probably emerged from an animal source, but now it seems to be spreading from person to person. It’s important to note that person-to-person spread can happen on a continuum. Some diseases are highly contagious (like measles), while other diseases are less so. At this time, it is unclear how easily or sustainably the virus that causes COVID-19 is spreading between people.

What are the symptoms of COVID-19?

Patients with COVID-19 have had mild to severe

respiratory illness with symptoms of:
– Fever
– Cough
– Shortness of breath

What can I do to protect myself?

The best way to prevent infection is to avoid being exposed to the virus that causes COVID-19.

Everyday things you can do to prevent the spread of respiratory viruses:

– Avoid close contact with people who are sick
– Avoid touching your eyes, nose, and mouth with unwashed hands
– Wash your hands often with soap and water for at least 20 seconds. Use an alcohol-based hand sanitizer that contains at least

60% alcohol if soap and water are not available.

If you are sick, to keep from spreading the respiratory illness

to others, you should:

– Stay home when you are sick
– Cover your cough or sneeze with a tissue,

then throw the tissue in the trash
– Clean and disinfect frequently touched objects and surfaces

Is there a vaccine or treatment?

There is currently no vaccine to protect against COVID-19. The best way to prevent infection is to avoid being exposed to the virus that causes COVID-19. There is also no specific antiviral treatment for COVID-19, but people with COVID-19 can seek medical care to help relieve symptoms.
