Are You Traveling Overseas?

As travelers gear up for international adventures, a recent alert from NSW Health warns about the increased risk of measles following an infectious individual's visit to Sydney Airport and other locations in New South Wales. The individual had just returned from Southeast Asia, where alarming outbreaks are reported in countries like Vietnam, Thailand, and Indonesia.

Measles is considered one of the most contagious diseases known. It spreads when an infected person breathes, coughs, or sneezes, with the potential to infect up to 18 other individuals who are not immune! Initial symptoms can mimic a common cold—fever, runny nose, cough, and conjunctivitis—but soon escalate into a non-itchy rash that can spread across the body. While children are the most vulnerable, adults are also at risk, representing up to 20% of measles cases during outbreaks.

Vaccination Saves Lives—Don't Delay!

The fight against measles took a significant turn with the introduction of the measles vaccine in 1963, saving approximately 60 million lives globally in the 21st century alone. The measles vaccine, available for free through Australia’s National Immunisation Program, is usually administered to children at 12 and 18 months as part of the combined MMR (measles, mumps, rubella) vaccine.

Despite unfounded claims linking the vaccine to autism, extensive research confirms its safety and efficacy. However, those with weakened immune systems, like individuals undergoing chemotherapy or pregnant women, are advised against vaccination. For them, community immunity is essential to safeguard against measles.

A staggering 95% community immunity is required to prevent outbreaks due to the virus's highly infectious nature. Unfortunately, gaps in global vaccination coverage are widening, worsened by pandemic disruptions. Data shows that as of 2023, only 83% of the world's children received their first dose of the measles vaccine by their first birthday, significantly below the threshold needed to halt the virus's spread.

Measles Outbreaks Are on the Rise—What It Means for You

The situation is urgent as measles cases spike globally. In Australia alone, 37 cases have already been reported in 2025, eclipsing the total of 57 from all of 2024. Most of these cases are imported and may carry the virus from popular tourist destinations like India, Thailand, and Vietnam, further complicating the scenario.

In addition, countries traditionally deemed safe from measles, including the U.S., U.K., and various European nations, are currently grappling with outbreaks. As the incubation period for measles is between seven to ten days, travelers may unwittingly transport the virus back home, putting entire communities at risk.

Essential Tips for Travelers—Stay Safe and Healthy!

Traveling soon? Ensure your family is protected! For children as young as six months heading to high-risk areas, early vaccination with the MMR vaccine may be advised. This extra dose won’t replace the standard vaccines offered at 12 and 18 months but serves as an interim safeguard.

All adults must be aware of their vaccination history. If unsure, consult with your healthcare provider regarding whether you need vaccination. It’s crucial to ensure you’ve received the two lifetime doses of the measles vaccine, especially if you've migrated from countries with lower vaccination coverage.

Upon return from your travels, if you exhibit symptoms indicating measles, communicate your recent travel history to your healthcare provider before seeking in-person medical care.

With the resurgence of measles threatening public health, now is the time to act! Ensure you and your family are vaccinated and ready for your next overseas adventure—before it’s too late!
