FOREWORD 1. About one third of the world's population is infected by Mycobucterium tuberculosis. Worldwide in 1995 there were estimated about nine million new cases of tuberculosis with three million deaths. M Tuberculosis kills more people than any other single infectious agents. Deaths from TB comprise 25% of all avoidable deaths in developing countries. 95% of TB cases and 98% of TB deaths are in developing countries, 75% of these cases are in the economically productive age group (15 - 50). 2. As a consequence, the world is facing a much more serious situation in the twenty-first century than that of the mid-1950s. Due to demographic factors, socio-economic trends, neglected TB control in many countries, and in addition, the HIV epidemic, there are many more smear positive pulmonary TB cases, often undiagnosed andlor uneeated. When TB cases are treated, poor drug rescripti ion and poor case management are creating more TB patients excreting resistant tubercle bacilli. 3. In 1991, the World Health Assembly adopted Resolution WHO 44.8, recognizing eflective case management as the central intervention for tuberculosis control': and recommending the strengthening of national tuberculosis programmes by introducing short course chemotherapy and improving the treatment management system. Since 1992, the WHO Global Tuberculosis Programme has developed a new strategy, to meet the needs of global tuberculosis control.
