Measles Surges: Bali, Vietnam, Thailand Travel Advisory

Australian health authorities are issuing warnings regarding measles outbreaks in popular Southeast Asian destinations, including Bali, Vietnam, and Thailand, urging travellers to check their vaccination status. Several Australian jurisdictions have reported measles cases, often connected to international travel, with a significant number originating from Southeast Asia. The risk of reintroducing measles into Australia, which was declared measles-free in 2014, is heightened during holiday travel periods.

Compounding the concern is a decline in measles vaccination coverage among young Australian children, with only 89.5% receiving the second recommended dose. This has led to local transmission, with some infections occurring without a clear overseas link. Measles is highly contagious, spreading through airborne particles, and can cause severe complications, including pneumonia and encephalitis. Achieving herd immunity requires about 95% of the population to be vaccinated.

Australians born in 1966 or later without two documented measles vaccine doses are advised to get vaccinated, ideally at least two weeks before travel. Infants as young as six months can receive an early dose if travelling. Vaccination offers robust protection, and ensuring up-to-date immunisation is vital for safeguarding individuals, communities, and vulnerable groups against this preventable disease.
