Abstract: Objective To understand the TB control work status of floating population in Bao’an district of Shenzhen. Methods We collected the case-based database of pulmonary TB cases registered from 2004 to 2007 in Bao’an chronic disease hospital. A total of 3027 cases were registered, among which 796 cases were of resident population, and 2231 were of floating population. We analyzed the features of TB epidemic in floating population. We also interviewed nine cases of TB patients, six TB doctors, and ten health administration leaders responsible for floating population TB management. Through the interview, we analyzed the health demand of floating population TB patients, their health seeking behavior and current status in their TB diagnosis, treatment, management and control policy.  Results The number of pulmonary TB cases registered in floating population was 2.8 times（2231/796） of that in resident population. 6.05%（135/2231）of TB patients were detected by passive case identification in floating population, the referral rate was 93.32％(2082/2231). Patients aged between 15 to 45 years old predominated in new smear positive patients was 93.80％(1739/1854). Case management was mainly through full course management, 97.93%(663/677)  for new smear positive pulmonary TB patients in 2007, the accumulative smear conversion rate at the end of third month was 92.99%(1724/1854). The cure rate was 46.33%（859/1854）because high proportion of patients missed treatment outcome information in the end.  Conclusion The number of TB registration in floating population is higher than in resident population, however, a large proportion of patients were loss to follow-up at the end of treatment. Therefore, we should strengthen the treatment management of TB patients and information connection and sharing.
