Nearly all of the confirmed cases of Wuhan coronavirus are in China, but the virus has spread across Asia and the rest of the world.
If you're worried, here are some tips for protecting yourself: Know the symptoms: Other symptoms of this coronavirus include fever and shortness of breath. Severe cases can lead to pneumonia, kidney failure and even death.
About meat and animals: Scientists believe this coronavirus started in another animal and then spread to humans. So health officials recommend cooking meat and eggs thoroughly.
Anyone with underlying medical conditions should avoid live animal markets and raw meats altogether, since those people are "considered at higher risk of severe disease," the World Health Organization says.
Take normal flu season precautions: In general, the public should do "what you do every cold and flu season," said Dr. John Wiesman, the health secretary in Washington state — where the first US case of Wuhan coronavirus was confirmed.
That includes washing your hands often with soap and water for at least 20 seconds.
If you feel sick: If you're the one feeling sick, cover your mouth and nose when you cough or sneeze, and disinfect the objects and surfaces you touch.
If you or your doctor suspect you might have the Wuhan coronavirus, the US Center for Disease Control advises wearing a surgical mask.
