Health officials said there are four additional cases, all from the same family. Two children and one adult are visiting from overseas; one other adult is an Allegheny County resident.
One of the patients visited the Enterprise Rental Car at 2260 Babcock Blvd. on Wednesday, May 1, between 2 p.m. and 3 p.m. on. Anyone who was there until 5 p.m. may have potentially been exposed.
The final patient's only public exposure was believed to be at Pittsburgh International Airport on Tuesday, April 16 between 7:30 a.m. and 10 a.m. The CDC has told Channel 11 this patient was a child, who flew to Pittsburgh on an international flight from Israel that stopped at Newark International Airport.
Health officials said most people are not at risk because they have been immunized or have had measles. Those born before 1957 are considered to be immune.
