Pediatric tuberculosis in immigrants to the United Kingdom from the Indian sub-continent.

Tuberculosis (TB) is now an uncommon disease in the United Kingdom (U.K.) and its overall incidence is declining. However, the incidence of TB in immigrants from India, Pakistan, and Bangladesh (the Indian sub-continent, ISC) is much higher than in the native white population or immigrant groups from other areas, and this is so even for children of ISC ethnic origin born in the U.K. The clinical pattern of the disease also differs, extrapulmonary involvement being commoner in ISC patients than white patients. The epidemiology and management of TB in pediatric patients of ISC origin is reviewed and reasons for differences from other ethnic groups in the U.K. are discussed.
