ObjectiveTo characterize the epidemic status and treatment outcomes of tuberculosis(TB)from 2008 to 2017 in Songjiang District of Shanghai for the development of TB prevention and control strategies.

MethodsAccording to case registration data in the TB management information system, statistical analysis was performed on the epidemic situation, epidemiological characteristics and treatment outcomes of TB cases in Songjiang District from 2008 to 2017.

ResultsThere were 5 516 reported cases in 2008-2017 in Songjiang District. The average annual reported incidence was 33.58/100 000, which was declining(χ² = 6.13, P < 0.05). The incidence was significantly higher in the floating population than that in the household registered population(χ² = 263.28, P < 0.05). In the cases, gender ratio was 2.17 : 1. More than 70% of the cases were between 15 and 44 years old. The majority of the cases were workers(34.95%), followed by housework or unemployed(16.28%). The proportion of TB case responding to the treatment was 93.38%, which was 93.41% for newly diagnosed cases and 92.86% for previously treated cases. The failure rate in the previously treated smear-positive cases was significantly higher than newly treated smear-positive cases(χ² = 4.96, P < 0.05).

ConclusionTB epidemic in Songjiang District remained at a low level in 2008-2017;however, it is far away from the termination of TB. We should further strengthen the prevention and control of TB, especially in the 15-44 years old workers and unemployed young population.
