1.1 Global Burden of TB

In 1996 there were about 9 million new cases of TB with 3 million deaths, worldwide. These deaths comprise 25% of all avoidable adult deaths in developing countries. 95% of patients, and 98% of deaths, from TB occur in developing countries. 75% of TB patients in developing countries are in the economically productive age group (15-50 years).

The increase the global burden of TB is due to a combination of:

· population growth
· rapid urbanization
· increasing poverty
· spread of HIV (in some regions of the world), and
· ineffective TB control programmes leading to the development of multiple drug resistant organisms.
