World Health Organization tuberculosis notification update, 1994

Abstract

More than three million cases of tuberculosis were notified in 1994, but the World Health Organization (WHO) estimates that over eight million cases might have occurred in the world. This under-reporting reflects missing or incomplete information or poor performance of the recording and reporting systems of some national tuberculosis control programs. Three quarters of the notified cases have been recorded in Asia and Africa. Underlying causes are poverty, urbanisation, malnutrition, and HIV.
