[Schistosomiasis surveillance in mobile population of Xiuzhou District, Jiaxing City, 2013-2014].

OBJECTIVE

To understand the schistosome infection situation of mobile population in Xiuzhou District.

METHODS

The data about the distribution of mobile population from the counties not reaching schistosomiasis transmission controlled in Xiuzhou District were collected, then the questionnaire survey combined with laboratory detection were used to investigate the situation of imported schistosomiasis in this district. In addition, the average infection rate and the estimated number of schistosomiasis patients were calculated.

RESULTS

From 2013 to 2014, there were 15 940 people from the counties not reaching schistosomiasis transmission controlled in Xiuzhou District, among which, 4405 were investigated, and 124 of them had schistosomiasis and treatment history. Thirty-eight people were positive in serological tests, and 3 cases were positive in the etiological detection. The average infection rate of schistosome of the mobile population in Xiuzhou District was 0.068%, the calculated number of schistosomiasis patients was 11.

CONCLUSIONS

The imported sources of infection are the main risk for the consolidation of the results of schistosomiasis control, which may result to the rebound of the endemic situation. So the management and surveillance of mobile population should be strengthened.
