TOKYO (Jiji Press) — Experts are calling on people to get vaccinated against measles, citing concerns about a possible outbreak as travel between Japan and abroad is becoming active again after COVID-19 restrictions were lifted.

In Japan, where there is no indigenous measles virus, 10 infection cases had been reported this year as of May 28, according to the National Institute of Infectious Diseases. Experts pointed to the possibility of infections with the virus from foreign countries.
