Confirmed cases of measles have now been reported at two public health units in southern Ontario.

Grand Erie Public Health said nine people have the highly contagious virus.

Of those, three are children and the remaining six are adults.

Only one of those cases is in Brantford-Brant, while the other eight are in Haldimand County and Norfolk County.

Southwestern Public Health, which covers Oxford County, Elgin County and St. Thomas, confirmed Thursday they have one active case. Officials believe it is likely connected to those reported by Grand Erie Public Health.
