ASAHIKAWA, Japan, Dec. 3 (UPI) -- About one in 10 high school students in Japan, and 23.5 percent of 16-year-old girls, are infected with a sexually transmitted disease, a medical survey shows.
According to a survey conducted by Asahikawa Medical College in Hokkaido, the first of its kind in the nation, Japan has among the worst rates of chlamydia infection in the world. The infection rate for this disease is less than 2 percent in Europe and the United States, one of the researchers noted.
The survey questioned 3,190 high school students at 13 schools in Hokkaido on their sexual experiences, and examined samples of their urine, reported the Yomiuri Shimbun Friday.
If left untreated the disease, known as a silent disease because it has few symptoms, could damage the female reproductive organs. Moreover, people infected with chlamydia are much more likely to get infected with HIV/AIDS if exposed to the virus.
