Federal health officials said an Illinois business associate of a man treated for MERS in Indiana earlier this month has tested positive for the disease but shows no signs of illness, NBC5 is reporting.
The Illinois man had not traveled outside of the U.S. recently and did not seek or require medical care, officials with the Centers for Disease Control and Prevention said, according to NBC 5.
The CDC said tests show the Illinois man probably was infected with the virus after having close contact twice with the patient diagnosed with MERS, or Middle East respiratory syndrome, in Indiana.
The Indiana man was treated at Community Hospital in Munster and released May 9 after health officials determined he posed "no threat to the community."
The man diagnosed in Munster had fallen ill shortly after arriving from Saudi Arabia where he lived.
Community Hospital employees identified as having come in contact with the man before he was diagnosed were cleared to return to work earlier this week.
The Illinois man contiues to feel well, so is not an official MERS case, CDC officials said, according to NBC5.
The new case was detected as part of efforts by CDC and state health departments to contact everyone connected with the Indiana man and a Florida man who was the second in the U.S. diagnosed with MERS May 11, NBC5 reported.
Most cases of MERS have been in Saudi Arabia or elsewhere in the Middle East. The case confirmed May 11 was in a man from Saudi Arabia who was visiting Florida.
