Measles is an airborne infectious disease with an extremely high rate of transmission. If a person without immunity comes into contact with a patient, the likelihood of infection can exceed 90%.

Symptoms of measles include fever, cough, runny nose, conjunctivitis, and a widespread rash. In particular, infants, young children, pregnant women, and others with weakened immune systems are at high risk of developing severe complications such as pneumonia or encephalitis. Therefore, those who have not completed two doses of the measles (MMR) vaccine or whose vaccination status is unclear should check their immunization records before traveling.


The influenza season in Japan also began earlier than usual this year. In 2026, the influenza outbreak started in week 34, which is five weeks earlier than the average. When visiting places with large crowds, such as festivals or multi-use facilities, travelers are advised to wash their hands, practice proper cough etiquette, and wear a mask if they develop respiratory symptoms to prevent infection.

Travelers to Southeast Asian countries such as Vietnam, Thailand, and the Philippines should be vigilant about mosquito-borne diseases like dengue fever. It is recommended to apply mosquito repellent every three to four hours and wear long, light-colored clothing. If you are bitten by mosquitoes or develop symptoms such as fever, headache, or muscle pain upon arrival, you should report it to a quarantine officer and receive a free dengue fever test.
