Abstract
Objective: The aim of this study was to clarify trends in foreign-born tuberculosis (TB) patients in Kagawa Prefecture and to examine issues and future measures for regional public health administration.
Methods: A descriptive epidemiological study of newly registered TB patients was conducted using the Japan Tuberculosis Surveillance data from 2016 to 2022. The analysis included demographic characteristics, countries of birth, occupations, methods of detection and treatment outcomes of foreign-born and Japan-born patients. We then compared the characteristics of patients nationwide, in Osaka Prefecture, and in Kagawa Prefecture.
Results: In Kagawa Prefecture, the proportion of foreign-born TB patients increased annually, exceeding that in Osaka Prefecture and nationwide. Foreign-born TB patients were predominantly young adults in their 20s and 30s, with a higher proportion of females. Most of them were from Vietnam, Indonesia, Myanmar, and the Philippines. More than half were regular workers or students, and many cases were detected through routine health check-ups. The proportion of successful treatment in Kagawa Prefecture was higher than that in Osaka Prefecture and nationwide. There were few cases of multidrug-resistant TB or TB/HIV
co-infection.
Conclusion: It is important to address the issues of TB among young foreign-born workers in Kagawa Prefecture. Strengthening collaboration with workplaces and enhancing support systems that enable patients’ continuity of treatment and employment are essential.
