title: Tuberculosis in an indigenous young white south Wales population.
abstract: Concerns about tuberculosis in young people in two linked deprived non-metropolitan communities triggered an investigation into local disease incidence and control measures. A pragmatic case-finding exercise, epidemiological enquiry and DNA genotyping were carried out to establish incidence and connections between cases over a five-year period. Of the 91 cases identified, 88 were from the white indigenous population. Approximately one third of cases were aged under thirty. Eight disease clusters were identified. Epidemiological investigation found spurious links between these, and DNA genotyping was necessary to clarify links. Seven cases and several contacts had been in prisons throughout the United Kingdom. Index cases under thirty generated more contacts, more contacts needing prophylaxis and more secondary cases than older patients. The workload resulting from tuberculosis control in younger cases was considerable. Tuberculosis remains an important problem in this population.
