An unvaccinated child and another adult from the north contracted measles, the Health Ministry reported on Thursday.
So far, five cases of measles have been uncovered in Israel's north in the last month.
Following an epidemiological investigation conducted in the region, a link was found between the cases.
The source of the illness is a person who contracted measles abroad about a month ago and stayed in the emergency room at Furia Hospital, Israeli media added.
