Out of 31 confirmed cases of infection, the NCoV virus has killed at least 18 people

The virus is related to one that causes the common cold, also a coronavirus

NCoV has been compared to SARS, which killed about 10% of its confirmed victims

(CNN) —  

A newly discovered and often deadly virus related to one that causes the common cold has struck another victim, this time in France.

A man hospitalized in April is infected with the novel coronavirus, France’s Health Ministry said Thursday.

NCoV virus was recently found for the first time in humans and scattered reported cases have occurred across parts of the Middle East, particularly Saudi Arabia.

It has proved deadly in more than half of the confirmed cases so far, according to the World Health Organization. Of 34 people with confirmed infections, at least 18 have died.

Infectious disease specialists believe the virus is very difficult to catch.

The two infected men are the first confirmed cases in France. The first patient had recently returned from the United Arab Emirates, the French Health Ministry said.

Identifying the source of that man’s ailment took time, the ministry said. France’s Pasteur Institute confirmed the case Wednesday. The Health Ministry identified 124 people who had contact with the man.

NCoV, like some common colds, is also caused by a coronavirus. And like a cold, it attacks the respiratory system, the Centers for Disease Control and Prevention have said.

But symptoms are severe and can lead to pneumonia and even kidney failure.

“Once it gets you, it’s a very serious infection,” said Dr. William Schaffner, an infectious disease specialist at Vanderbilt University Medical Center in Nashville.

NCoV has also been compared to related coronavirus, the one that causes SARS, or severe acute respiratory syndrome, which appears to have been contained in 2004, according to the CDC.

Although its discovery in humans is new, NCoV would seem potentially deadlier, when contracted, than SARS.

Of the some 8,000 verified cases of SARS, fewer than 800 people – less than one-tenth of those infected – died.
