A survey was conducted by the National Tuberculosis Programme in 44 Malawian hospitals on screening young children aged 5 years or less in households of adults diagnosed with smear-positive pulmonary tuberculosis. Of 659 hospitalised adult patients, 267 (41%) had a total of 365 young children; 56 (21%) adult patients had been informed about childhood screening, and in 31 (12%) some of their children were screened. Of the 365 young children, 33 (9%) were screened for TB--23 received isoniazid preventive therapy, six received anti-tuberculosis treatment, and in four no action was taken. Steps are needed to improve childhood screening procedures.
