What is a coronavirus?

Coronaviruses are a large family of viruses that cause disease1 in mammals and birds. Coronaviruses can cause illnesses that range from the common cold to much more severe illnesses like Middle East Respiratory Syndrome2 (MERS) and Severe Acute3 Respiratory Syndrome (SARS).

Experts still do not have a clear picture of the severity of the new coronavirus.

What is a new coronavirus?

Officials are calling the disease a "novel" or new coronavirus because it has not been found before in humans.

The newly4 identified virus is thought to have spread to humans from wild animals sold at a market in Wuhan, in central China's Hubei province. But it is now spreading between people.

Chinese officials say the disease is able to spread from one person to another even before any actual signs appear. This makes it especially hard to contain.

What are the signs of the new coronavirus?

Signs of the disease among infected patients have included fever, cough, shortness of breath and general breathing difficulties. In more severe cases, the virus can cause pneumonia5.

Some people report few or no signs, while others have gotten very sick or even died.

The U.S. Centers for Disease Control and Prevention reports that signs of the virus may appear between two and 14 days after being near someone who is infected.

Treatment and Prevention

There is no special treatment for the new coronavirus. However, many of its effects are treatable, as long as a patient is in fair health.

Because the virus is so new among humans, there is no available vaccine6 to protect against the disease. But the World Health Organization advises people to avoid close contact with anyone showing signs of a breathing sickness, such as coughing or sneezing. It also says people should wash their hands often and use safe food practices.

The U.S. Centers for Disease Control also published prevention tips. It says wash your hands for at least 20 seconds with soap and water; avoid touching7 your face with unwashed hands; stay home when you are sick; and clean objects and surfaces that are touched often.
