A novel coronavirus was identified in 2012 as the cause of respiratory illness in people. Their symptoms included fever, cough, and shortness of breath. Some of the reported cases were mild. Investigators are trying to figure out the source of the novel coronavirus and how it spreads. There are no reported cases in the United States.

What Are Coronaviruses?

Coronaviruses are named for the crown-like spikes on their surface. They are common viruses that most people get in their lifetimes. These viruses usually cause mild to moderate upper-respiratory tract illnesses.

Coronaviruses may also infect animals. Most of these coronaviruses usually infect only one animal species or, at most, a small number of closely related species. However, SARS coronavirus can infect people and animals, including monkeys, Himalayan palm civets, raccoon dogs, cats, dogs, and rodents.
