Cases of measles have been confirmed one after another in Japan. Since the COVID-19 pandemic started, the spread of other infectious diseases has tended to be forgotten about, but vigilance must be maintained.

The number of measles patients this year reached 10 as of May, already exceeding the total for all of last year. The disease has also been spreading widely overseas. There was even a case of transmission aboard a Shinkansen train from a person who developed measles symptoms after returning from India.
