Travellers to the Philippines should ensure that they are up-to-date with recommended measles-mumps-rubella (MMR) vaccination. The Northern Territory health department has alerted the public to a case of measles in a traveller returning to Darwin from the Philippines adding to previous alerts from New South Wales and Victoria. Japan has recorded 17 similar cases, and the latest Health Protection report from the United Kingdom also records 10 cases of measles imported from the Philippines. While strenuous efforts are being made in that country to control the prevalence of measles there is still a high incidence of children and adults unprotected by vaccination. While children in Australia born after 1981 should have been vaccinated it is wise to check that a full course of two vaccinations has been given.Adults born between 1966 and 1981 should be vaccinated before travel unless there is clear evidence of immunity.
