Abstract
A measles outbreak occured in Tsubetsu, Hokkaido, between February and March, 1987. The outbreak was peculiar in that junior high school students mainly contracted measles. We investigated the cause of the outbreak of measles among adolescents with the cooperation of the elementary schools and the junior high schools in Tsubetsu, Tsubetsu Hospital and the regional health center in Bihoro. Five elementary school students and eighteen junior high school students contracted measles in Tsubetsu between February and March, 1987. On the other hand, the patients who were diagnosed as measles at Tsubetsu Hospital consisted of two infants, two elementary school students, eight junior high school students, three high school students and two adults.In Tsubetsu, the rate of measles vaccination was 64.5 percent after the enforcement of the measles vaccination in 1979. The vaccination rate was too low to prevent measles outbreaks. We concluded that this low level of vaccination permitted the measles outbreak among adolescents who remained susceptible to measles.It has been known that serum level of lactate dehydrogenase is increased in measles patients, and we reconfirmed it in this outbeeak. It might be helpful for atypical cases of measles.
