Measles in Japan: a resurgence linked to international travelers

Japan, which had declared measles eliminated, is facing a resurgence of cases imported by international travelers. According to local media, declining vaccination rates in certain countries and post-pandemic travel are fueling transmission. Measles is extremely contagious: one infected person can infect 90% of unimmunized people around them.

If you're planning a trip to Japan, or if you're receiving visitors from at-risk areas, your vaccination status is crucial. Measles can be serious in adults: respiratory complications, encephalitis, hospitalization. In Cambodia, accessing care for a preventable disease is something to avoid. Remember to check your vaccination record and that of your children.

Here are the steps to follow:

• Check if you've received two doses of the MMR vaccine (measles-mumps-rubella).
• If you were born after 1980 and have only one dose or none, consult a doctor for an update.
• Before traveling to Japan, ensure you're protected at least two weeks before departure.
• If you develop symptoms (fever, cough, rash), wear a mask and seek medical attention promptly.

Don't assume measles is a benign childhood disease: in adults, complications are common. Avoid relying on supposed immunity if you had measles as a child: vaccination is still recommended. Finally, don't neglect vaccination updates on the grounds that you're in good health: measles can be serious even without risk factors.

The situation in Japan could worsen with the influx of tourists during cherry blossom season. Japanese authorities may strengthen health controls at airports. Stay informed through official channels and WHO alerts. If you travel, purchase travel insurance covering medical expenses abroad.
