(CNN) - The World Health Organization says at least a dozen people have become sick with the new virus it calls NCoV or novel coronavirus.

This potentially fatal SARS-like virus was first identified in September of last year.

Symptoms of infection with the virus include an acute respiratory infection, fever and a cough. Others have suffered pneumonia and kiney failure.

Fortunately, doctors say the virus appears to be hard to get and there's no evidence of sustained human-to-human transmission.

So far, it has only showed up abroad, but experts say they wouldn't be surprised if it appeared in the U.S.

The centers for disease control and prevention is advising doctors to ask patients with certain symptoms about their recent travels.
