UPDATE: Third Confirmed MERS Case in Illinois

An update on the spread of the Middle East Respiratory Syndrome, or MERS, virus in the United States.

Health experts say an Illinois man, who had business dealings with an Indiana MERS patient, tested positive for the virus.

The Centers for Disease Control and Prevention says the virus probably spread through a handshake.

This is the third confirmed case in the US. The second case was confirmed in Florida.

But experts still believe the risk to the general public is low.

Dr. William Schaffner of Vanderbilt University Medical Center said, “They were in the same breathing zone, the two of them, this is the kind of thing that will happen from time to time.”

The CDC posted warnings about the virus in US airports and does not plan to take any further precautions.

There is no vaccine, but patients can be treated to relieve symptoms which include fever, cough, chills, body ache and sore throat.
