[An approach to tuberculosis in newcomers from Asia and Africa]

In recent years, it has been documented that tuberculosis frequently occurs among recently entered foreigners dominantly from Asia. We studied 85 cases admitted to our hospital for active tuberculosis from 1986 to 1990. Many of those cases, we believe, were infected in countries of origin and were reactivated soon after or before entering Japan. In spite of higher rate of involving recurrent cases and resistance to anti-mycobacterial drug agents, chemotherapy has been generally efficient. In some cases, continuance of treatment was difficult because of their illegal stay, misunderstanding of the disease or other problems such as customs and economic difficulties.
