The epidemic trend and characteristics of tuberculosis for local population and migrants from 2010 to 2017 in Jiading, China

Abstract

In the present study, we analyze the epidemic trend and characteristics of pulmonary tuberculosis (PTB) registered in the Jiading Industrial Zone, Shanghai from 2010 to 2017, and the information concerning delays in visit to hospital, diagnosis, and treatment. The most important purpose was to reveal the difference in PTB characteristics between local population and migrants. Tuberculosis epidemic data were collected from the National Information System for Disease Control and Prevention (NISDCP) and the specific Jiading system for tuberculosis patients between 2010 and 2017. Descriptive statistics were produced for the epidemic trend and characteristics of PTB cases. The epidemic trend of PTB for migrants was different from the trend for the local population. The peak months for the presentation of migrant TB cases were July, September, and April. The peak months for the presentation of local TB cases were November, July, and April. The two age groups with the greatest percentage of migrant TB cases were 25–34 years and 15–24 years, and the two age groups for the local TB cases with the greatest percentage were ≥ 65 years and 45–54 years. A certain proportion of patients had a delay in visit to hospital (41.00%), delay in diagnosis (26.04%), and delay in treatment (1.38%). Shanghai is a domestic immigration city; a tuberculosis epidemic cannot be ignored. In the current study, local population and migrants have different epidemiological characteristics of tuberculosis. Therefore, different strategies and measures should be adopted for local populations and migrants. In addition, publicity and education concerning early detection and early treatment should be strengthened.
