To determine the prevalence of tuberculosis (TB) infection in Year 8 schoolchildren (aged 12‐14 years) in Sydney. Cross‐sectional survey. 22 inner city Sydney secondary schools. 2290 Year 8 school children enrolled in 1992. Distribution of Mantoux test reaction size and proportion of children who were Mantoux positive (i.e., having Mantoux reaction >15mm with previous Bacille Calmette‐Guérin vaccination; >10mm without). Of the 2290 children, 1836 (81%) were screened and 1801 Mantoux reactions were read. Ten per cent of children were Mantoux positive — 27% of foreign‐born children and 2% of Australian‐born children (relative risk 16.7, 95% confidence interval 10.6‐26.4). Two children were found to have active TB disease. There is a high prevalence of primary (non‐contagious) TB infection in children aged 12‐14 years in inner Sydney, mostly confined to children born overseas. Thus there is a large pool of infected children at risk of developing active (contagious) adult‐type TB disease in the future. This public health problem should be addressed by identification and treatment of those infected. |
