what is coronavirus?
Coronaviruses are a family of viruses that range from the common cold to MERS coronavirus, which is
Middle East Respiratory Syndrome coronavirus and SARs, Severe acute respiratory syndrome
coronavirus.
Where do coronaviruses come from?
Corona viruses are circulating in animals and some of these coronaviruses have the capability of
transmitting between animals and humans. We call that a spillover event.
How can I help protect myself from a coronavirus?
The coronaviruses typically cause respiratory symptoms. So we recommend basic hand hygiene, such
as washing your hands with soap and water and respiratory hygiene, such as when you sneeze,
sneezing into your elbow.
Ways to protect yourself against a potential animal source would be to avoid unnecessary
unprotected contact with live animals and to make sure that you wash your hands thoroughly after
contact with animals and also to make sure your meat is cooked thoroughly before consuming.
Is there treatment?
There are no specific treatments for coronaviruses, but symptoms can be treated.
Prevention for 2019 Novel Coronavirus
There is currently no vaccine to prevent 2019-nCoV infection. The best way to prevent infection is to avoid being exposed to this virus. However, as a reminder, CDC always recommends everyday preventive actions to help prevent the spread of respiratory viruses, including:
- Avoid close contact with people who are sick.
- Avoid touching your eyes, nose, and mouth with unwashed hands.
- 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 using a regular household cleaning spray or wipe.
- Follow CDC’s recommendations for using facemask.
- CDC does not recommend that people who are well wear facemask to protect themselves from respiratory viruses, including 2019-nCoV.
- Facemask should be used by people who show symptoms of 2019 novel coronavirus, in order to protect others from the risk of getting infected. The use of facemasks is also crucial for health workers and people who are taking care of someone in close settings (at home or in a health care facility).
- 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 are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty.

These are everyday habits that can help prevent the spread of several viruses. CDC does have specific guidance for travelers.Info for Travelers
Treatment for 2019 Novel Coronavirus
There is no specific antiviral treatment recommended for 2019-nCoV infection. People infected with 2019-nCoV should receive supportive care to help relieve symptoms. For severe cases, treatment should include care to support vital organ functions.
People who think they may have been exposed to 2019-nCoV should contact your healthcare provider immediately.
See Interim Guidance for Healthcare Professionals for information on persons under investigation.
