Information Center for Public Health, Chinese Academy of preventive Medicine, Beijing 100050, China; △ Beijing Research Institute for TB Control, Beijing 100035, China The study investigated the burden of smear positive pulmonary TB and its infectivity, using DALY (Disability Adjusted Life Year) as an indicator. An assumed cohort of 2000 cases was set up based on the age specific incidence of 794 newly registered smear positive cases of TB in Beijing in 1994. Prognostic trees and model diagrams of infectivity under natural history and DOTS (Direct Observed Treatment, Short course) strategy were established according to the epidemiological evidence. The results show that 29.6% of DALYs would be neglected if the burden caused by the infectivity was not considered. The results also show that DOTS strategy may reduce 97.3% of the number of potential cases infected, 92.9% of DALYs related to TB patients themselves, and 99.9% of DALYs caused by TB’s infectivity as well.
