In NSW, three laboratory confirmed measles cases were reported in April. The index case was a young adult who became ill after returning from a trip to Thailand. Two locally-acquired measles cases linked to the index case have subsequently been reported. One case was confirmed in an infant under 12 months of age and the other a young adult. The public health investigation of these cases is ongoing and a number of other close contacts at risk of infection are being actively followed up.
Measles is a serious and highly contagious disease that is spread from person to person. Travellers who have not been vaccinated are at risk of getting the disease and spreading it to infants who are too young to be immunised, and to their friends and family members who may not be up to date with their vaccinations.
Measles immunisation is highly effective in preventing the disease. All children and adults born during or after 1966 should be vaccinated with two doses of the measles-containing MMR vaccine if not already immune.
