Steep increases in tuberculosis notification among young men in the industrialised districts of Danang, Vietnam.
BACKGROUND
Tuberculosis (TB) notification is increasing among young adults in urban provinces in Vietnam, despite having achieved World Health Organization targets for treatment success and case detection.


OBJECTIVE
To identify causes for non-declining TB case rates in an urban area of Vietnam, and to describe trends in new smear-positive pulmonary TB notification by age, sex and district in the period 1999-2004 in Danang City, Vietnam.


RESULTS
Age and sex-standardised notification rates declined by 1.3% (95%CI -2.3-0.3%) annually. Notification rates among men aged 15-44 in Danang City increased significantly (5%, 95%CI 2.4-7.7 annually), most notably in industrialised districts (>or=12% annually).


CONCLUSIONS
TB notification rates among young men in an urban setting in Vietnam increased most notably in industrialised districts. We hypothesise that this is due to poor living and working conditions and internal migration rather than to an emerging human immunodeficiency virus epidemic.
