Health problems among Vietnamese refugees resettled in Japan

A medical examination of 932 Vietnamese refugees was conducted within 1 month of their resettlement in Japan between 1989 and 1991. A variety of abnormalities were detected, including parasitic disease (78% prevalence), anemia (12%), HBsAg positive state (14%), liver dysfunction (10%), hypertension (0.8%), active pulmonary tuberculosis (2%) and syphilis (0.7%). These rates were still as high as the prevalence in previous studies of earlier immigrants from Vietnam. The high frequency of infectious diseases in recent Vietnamese refugees compared with the Japanese community leads to a recommendation for continuing medical examinations and treatment for new Vietnamese refugees.
