Epidemiology of childhood tuberculosis in a hospital setting.

A study of two hundred cases of tuberculosis over a span of two years was carried out at the pediatric department of a hospital in Islamabad. The diagnosis was based upon history, clinical examination, chest and other relevant radiography, Mantoux test, erythrocyte sedimentation rate (ESR) and where necessary cerebrospinal, pleural and ascitic fluid examinations and lymph gland histopathology were done. An equal number of male and female children upto 12 years of age were enrolled. The children usually presented with fever, cough, weight loss or failure to thrive and pallor. The most commonly affected age group was between 2-5 years and pulmonary tuberculosis was the most frequent diagnosis followed by tuberculous adenitis.
