Measles Cases Surge Globally, Prompting Vaccination Concerns in Australia
With rising measles cases in the US and other countries, health officials warn of potential outbreaks in unvaccinated communities in Australia.
A measles outbreak in the United States has resulted in the deaths of two individuals, alongside hundreds of infections and numerous hospitalizations among children.
The Centers for Disease Control and Prevention (CDC) reports that more than 370 cases of measles have been confirmed across 17 states this year, with 64 hospitalizations attributed to the disease.
The outbreak stems from communities with low vaccination rates, raising concerns among health officials regarding the risk of similar scenarios in Australia.
Historically, measles was considered eliminated in the US, a status achieved through the widespread administration of the measles, mumps, and rubella (MMR) vaccine.
However, the current outbreak highlights the vulnerability of populations where vaccination rates fall below the critical threshold of 95% necessary to prevent the spread of the disease.
In 2024, the US has already exceeded the previous year's total of 285 confirmed cases, indicating a worrying trend as the number of outbreaks continues to climb.
Most cases are linked to those who are unvaccinated or whose vaccination status is unclear.
Notably, 90% of this year's confirmed cases (341 out of 378) are related to identified outbreaks.
Vaccination rates have been declining in the US since the COVID-19 pandemic, with many states reporting that kindergarten vaccination levels are insufficient to curb outbreaks.
Internationally, the situation remains concerning.
In Mexico, authorities have launched an intensified vaccination campaign following a surge of measles cases, including 39 confirmed cases in the Chihuahua region.
Meanwhile, Vietnam is grappling with an ongoing outbreak, reportedly logging around 40,000 suspected cases this year.
Europe has also seen a resurgence, with cases doubling to a 25-year high in 2024, as the World Health Organization (WHO) reported over 127,000 cases last year in its European region, which encompasses 53 countries.
In Australia, the Department of Health’s National Notifiable Disease Surveillance System has recorded 37 confirmed measles infections this year, marking an increase from 26 cases in 2023 and 57 cases in 2024. Since being declared measles-free in 2014, Australia remains vulnerable to the introduction of the virus through international travel.
Most current cases are linked to returned travellers and their close contacts, with the majority detected in New South Wales and Victoria.
Notably, vaccination rates in Australia have dipped below the WHO target of 95%, prompting health officials to express concern over the risk of outbreaks.
Experts indicate that vaccination coverage has been declining since the onset of the pandemic.
Associate Professor Frank Beard from the National Centre for Immunisation Research and Surveillance suggests that the decline is particularly evident in certain demographics.
Pediatrician Margie Danchin highlighted a notable decrease in vaccination rates among First Nations children and specific regions, particularly in northern Australia.
Danchin outlined that while skepticism toward vaccines exists, practical barriers such as access to appointments and financial constraints are significant contributors to the decline in vaccination uptake.
Health officials stress the importance of addressing these gaps in vaccination coverage, particularly as international travel continues to pose a risk of importing measles back into the country.
The ongoing situation underscores the need for heightened awareness and action to bolster vaccination rates in vulnerable communities across Australia.
