(AP) -- The MERS Virus has spread from a patient in Indiana to a man from Illinois. It's the first time MERS has spread in the United States. What's unclear is whether or not this man was ever contagious himself.
Health experts long suspected it was just a matter of time. Now, the confirmation that MERS is on the move here at home.
It was the nation's first known patient, a man in Indiana, infected in Saudi Arabia that passed the virus forward to a business contact in Illinois.
He was tested by CDC along with everyone who had come into contact with the Indiana patient. Their closest contact, a handshake.
The 3rd MERS patient had two business meetings with the Indiana patient during the last week of April. On May 5th he was tested but the results were negative.
A second test on May 16th showed he'd been infected though he barely displayed any symptoms.
According to Dr. LaMar Hasbrouck of the Illinois Department of Public Health, "Every single case is different. It is a spectrum of possibilities and we're trying to learn as much as we can."
