The Durham Region Health Department is investigating a confirmed case of measles in the region after an adult was exposed during a recent trip abroad.

In a news release on Wednesday, the health department confirmed that “a local adult” is currently isolating at home after acquiring the illness, but it is not mentioned where in Durham region the adult resides.

Durham health has determined that individuals who travelled on the Royal Jordanian Airlines RJ271 flight on Thursday, March 28 departing from Jordan at 10:43 a.m. and arriving to Pearson airport on the same day at 5:24 p.m. local time — may have been exposed to the virus.
