Global tuberculosis control : WHO report 1998

Overview

This is the second annual compilation of data by the World Health Organization’s (WHO) tuberculosis surveillance and monitoring project. In May 1997, two hundred and twelve countries, territories and areas were asked to provide information about TB control policy, case notifications for 1996 and treatment outcomes for 1995. One hundred and eighty-one of 212 countries (85%) submitted data to WHO in 1997, covering 97% of the global population. They reported 3.81 million cases of tuberculosis, of which 1.29 million were smear-positive. Compared with estimated annual global incidence, these figures represent case detection rates of 39% and 51%, respectively.
