Measles Risk Rises at Travel Hotspots: Are You Vaccinated?

Measles Risk in Popular Destinations: What Travelers Need to Know

As measles outbreaks continue in several travel hot spots, health authorities are stressing the importance of vaccination before international trips. New data from Korea’s disease control agency show an uptick in measles cases among travelers returning from countries with active outbreaks, including Vietnam, South Africa, Uzbekistan, Thailand, Italy, and Mongolia. The spread is linked to gaps in vaccination coverage and disruptions to health services during the COVID-19 pandemic, which have left immunity levels below the recommended standard in some regions.

Country-by-country risk and vaccination guidance

Vietnam
– Risk level: High
– Vaccination recommendation: Travelers should be up-to-date on the MMR vaccine (measles, mumps, and rubella). If staying in rural areas for extended periods, consider vaccines for hepatitis A and typhoid.

South Africa
– Risk level: Moderate to High
– Vaccination recommendation: MMR vaccination is essential for travelers, especially to regions with active outbreaks. Additional vaccines for hepatitis A, hepatitis B, and cholera may be advisable in rural or underserved areas.

Uzbekistan
– Risk level: Moderate
– Vaccination recommendation: MMR vaccination is strongly advised for travelers. Hepatitis A and typhoid vaccines are also recommended, particularly for longer stays or rural travel.

Thailand
– Risk level: Moderate to High
– Vaccination recommendation: Ensure MMR vaccination is up to date. Vaccinations for hepatitis A, hepatitis B, and typhoid are recommended for longer trips or stays in areas with higher risk.

Italy
– Risk level: Moderate
– Vaccination recommendation: Make sure MMR vaccination is current before visiting. While Italy has a high overall vaccination rate, some regions have experienced recent outbreaks. Consider flu vaccination during colder months for extended stays in crowded places.

Mongolia
– Risk level: Moderate
– Vaccination recommendation: Travelers should be up-to-date on MMR vaccines. Hepatitis A and typhoid vaccines are worth considering, especially when traveling outside major cities.

Why vaccination is essential

Measles is an extremely contagious viral disease that spreads through the air. It can cause severe complications, including pneumonia, brain inflammation (encephalitis), and even death, particularly in infants and people with weakened immune systems. Vaccination remains the most effective protection. The two-dose MMR schedule provides the best protection, and adults who did not receive both doses in childhood should consider completing the series before travel.

What travelers should do

– Check your vaccination status: Ensure you and your family are up-to-date with the two-dose MMR vaccine. If in doubt, consult a healthcare professional and obtain the vaccine well before departure.
– Travel with records: Carry documentation of your vaccination history in case proof is requested.
– Monitor health after travel: If you develop fever or a rash within three weeks of returning from a measles-affected country, seek medical care promptly and tell your provider about your travel.
– Protect vulnerable groups: Infants, pregnant travelers, and people with compromised immune systems should take extra precautions and consult a healthcare professional before travel.

The role of travel health advisories

Travel health advisories from organizations like the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) provide up-to-date outbreak information, vaccination recommendations, and health risk guidance for different destinations. Check these resources before planning international trips, especially to regions with known measles activity.

Summary

With measles activity rising in several popular destinations, vaccination—particularly the two-dose MMR schedule—remains the most effective defense. Travelers should verify their immunization status, obtain the MMR vaccine if needed, and stay informed through reputable health advisories. By taking these precautions, travelers can protect themselves and others while enjoying safer trips abroad.

A hopeful note: widespread vaccination and adherence to travel health guidance can help prevent outbreaks and allow people to travel with greater confidence and peace of mind. If you’d like, I can tailor a quick pre-travel vaccination checklist based on your destination and trip length.
