Parents are being warned to be aware of measles outbreaks if they are travelling to the UK or Europe with children who have not been immunised.
Outbreaks of the disease are being seen in most European countries at the moment. Italy and Romania are the worse affected areas.
In Italy 48 people have died of measles since 2016, while both Italy and Romania had more than 5,000 cases last year.
The outbreaks are also being seen in England due to travel to and from Europe.
There have been fewer than five confirmed measles cases in Jersey over the past decade.
Doctors in Jersey are being asked to offer the MMR vaccine to islanders who did not have the recommended two doses when they were younger.
