[Caution] Endemic of measles and rubella in Japan

Since 2018 late-April, measles has been remaining highly endemic in Japan. Moreover, starting from this year, rubella has been spreading over the country. According to an emergency announcement of National Institute of Infectious Diseases, 528 people became infected in the first seven weeks of 2019. Due to the situation, the Ministry of Health, Labour and Welfare of Japan revised the Ministerial Ordinance on Immunization Law and provided temporary inoculation of rubella-containing vaccine to adult male who did not infect by rubella or have a vaccination history.

For Hong Kong residents who plan to visit Japan during spring holiday, we recommend you to have vaccination before departure.
