Measles Alert: Victoria Faces Increased Risk & Exposure Sites | 2026 Update

Melbourne, Australia is experiencing an increase in measles cases, prompting a health alert from Victorian authorities. The alert, issued on February 21, 2026, highlights a growing risk, particularly in metropolitan Melbourne, with local transmission occurring among individuals who have not recently traveled internationally or been knowingly exposed to the virus.

According to data released by the Australian Center for Disease Control, as of February 19, 2026, 12 confirmed cases of measles have been reported in Victoria this year. This represents a significant increase compared to the 36 cases reported throughout all of 2025 and the 17 cases recorded in 2024.

Measles is a highly contagious viral infection that spreads through airborne droplets released when an infected person coughs or sneezes. Symptoms typically begin with fever, cough, runny nose and red, watery eyes, followed by a characteristic rash that spreads from the head to the body. Complications can include ear infections, pneumonia, and, in rare cases, encephalitis (inflammation of the brain).

Dr. Christian McGrath, Acting Chief Health Officer for Victoria, is urging anyone who has visited a known measles exposure site to monitor for symptoms for up to 18 days and seek medical attention if they develop. Currently identified exposure sites include Melbourne Airport, recent flights arriving in Melbourne from Sydney, Dubai, and Ho Chi Minh City, as well as several hospitals and medical centers. The Victorian Department of Health maintains an updated list of exposure sites, which is available to the public.

The increase in cases is particularly concerning as vaccination coverage in Australia remains below the 95 percent national target. Health officials note that the majority of recent cases in Victoria have occurred in individuals who were not fully vaccinated against measles. Measles requires two doses of the measles-mumps-rubella (MMR) vaccine for full immunity.

The CDC reports that as of February 20, 2026, 982 confirmed measles cases have been reported in the United States this year, with outbreaks occurring in multiple states. This underscores a broader global trend of increasing measles incidence, linked to declining vaccination rates in many parts of the world.

For individuals born during or after 1966, the Victorian Department of Health recommends ensuring they have received two doses of the MMR vaccine. Those unsure of their vaccination status are advised to consult with their healthcare provider. Infants aged 6 to 11 months traveling internationally can receive a state-funded dose of the MMR vaccine prior to departure.

Vaccination remains the most effective way to protect against measles. It is recommended that travelers ensure their routine vaccinations, including measles, are up to date at least two weeks before departure. Local Public Health Units are actively implementing campaigns to improve access to the MMR vaccine within the community.

Healthcare professionals are urged to remain vigilant for measles in patients presenting with compatible symptoms, especially those with a history of international or interstate travel. Suspected cases should be immediately tested, isolated, and reported to the Local Public Health Unit by calling 1300 651 160.

The current situation highlights the importance of maintaining high vaccination rates to protect both individuals and the community from the potentially serious consequences of measles. While measles is a preventable disease, its resurgence underscores the ongoing need for public health awareness and proactive vaccination efforts.
