Abstract: Objective To study the evolutive trend of the sputum positive tuberculosis incidence in Beijing.Methods To summarize the evolutive trend and its main explanations through analyzing the epidemical characteristics of sputum positive tuberculosis incidence and tuberculous infection, the implement of DOTS strategy, and the relationship among them in Beijing in 1980—2002.Results The sputum positive tuberculosis incidence had dropped significantly in 1980—2002; and the incidence dropping resulted mainly from notable declining of the incidence in low age groups (30 below people); the tuberculous infection descending in low age groups had caused the incidence declining; by controlling the infection sources, DOTS strategy had significantly reduced the tuberculous infection and tuberculosis incidence in low age groups, but had little effect on the infected people.Conclusion The sputum positive tuberculosis incidence in Beijing wouldn’t decline notably in near future.
