Health officials in Japan say nearly 470 people across the country have been infected with measles this year.
The National Institute of Infectious Diseases said 11 new cases were reported in the week up to May 5.
The officials said the number of patients this year has reached 467, or 1.7 times last year's total. They said 136 people were infected in Osaka and 71 in Tokyo.
The disease is highly contagious, causes fever and rashes all over the body, and can cause miscarriage or premature delivery.
The health ministry is calling on people who think they might be infected to call medical facilities first for consultation before making visits.
