Tsutsugamushi disease has been a notifiable disease in Japan since the implementation of the Infectious Diseases Control Law in April 1999. In order to assess the role of public health laboratories in detecting Tsutsugamushi disease, a questionnaire regarding routine testing of suspected cases of Tsutsugamushi disease was sent to 73 regional public health laboratories (47 prefectural laboratories and 26 municipal laboratories) in July 2001. The response rate was 92% (67/73 laboratories). It was found that most prefectural laboratories are well prepared to routinely receive and test specimens of suspected Tsutsugamushi disease cases. Additionally, we found that some regional public health laboratories are using two or more detection methods to improve the accuracy of their routine tests. In southern Japan. Kawasaki and Kuroki strains, strains endemic to the region, are widely used in addition to Kato, Karp, and Gilliam strains, the standard strains used for serum antibody tests in Japan. For the years 2000 and 2001, we found that for some prefectures, the annual number of cases confirmed by regional public health laboratories was nearly equal to the annual number of cases the prefecture reported to the National Notifiable Diseases Surveillance System. In these prefectures, it appears that an effective communication network has been established between physicians, public health laboratories, and local health centers, ensuring laboratory confirmation and proper notification.
