A U.S. citizen previously hospitalized in Indiana with Middle East Respiratory Syndrome, or MERS, has passed the potentially fatal virus to an Illinois man, federal health officials said Saturday.

Health officials originally contacted the Illinois resident earlier this month after learning that he had met with the Indiana patient on two occasions prior to the Indiana man’s hospitalization, according to a release from the Centers for Disease Control and Prevention.

An initial test of the Illinois man on May 5 came back negative for an active MERS-CoV infection, officials said. But further testing revealed that the man had in fact been previously infected with the virus.
