Here's a quick guide on the common symptoms of coronavirus, how it spreads and what you can do to lower your risk of getting it.

HOUSTON — As coronavirus, or COVID-19, continues to dominate the headlines, it's important to stay informed and to resist spreading unconfirmed rumors. 

Here's a quick guide on the common symptoms of coronavirus, how it spreads and what you can do to lower your risk of getting it.

Coronavirus symptoms

The symptoms of coronavirus are similar to the flu or a bad cold. Symptoms include a fever, cough and shortness of breath, according to the Centers for Disease Control.

Most healthy people will have mild symptoms. A study of more than 72,000 patients by the Centers for Disease Control in China showed 80-percent of the cases there were mild. 

But infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death, according to the World Health Organization. Older people with underlying health conditions are most at risk. 

The CDC believes symptoms may appear anywhere from two to 14 days after being exposed.
