Abstract:
Objective To understand the reporting situation of schistosomiasis cases in National Notifiable Disease Report System (NNDRS) in China from 2015 to 2017, and to seek current deficiencies on case reporting as well as to analyze the epidemiological characteristics of schistosomiasis cases. Methods The data of schistosomiasis cases in China from 2015 to 2017 were collected from NNDRS, and the reporting situation and epidemiological characteristics of schistosomiasis cases were analyzed. Results From 2015 to 2017, totally 59 981 schistosomiasis cases were reported in China, among which, 1 460 cases were deleted, and 58 521 were censored cases. The statistics and analysis showed that a part of the case reporting had been carried out in nonstandard ways, mainly involving the random deletion of cases, reporting time not compliance with regulations, incorrect classification, and severe omission of cases. Among the 58 521 censored cases, the sex ratio of the male to the female was 1.83∶1, the average age of the cases was (51.91 ± 11.30) years, and farmers and fishermen accounted for 93.26% (54 577 cases) and 3.46% (2 022 cases), respectively. The reported cases mainly concentrated in Anhui, Hunan, Hubei and Jiangxi provinces, accounting for 99.73% of the total number in China. During this period, Beijing, Zhejiang and other provinces (cities and regions) reported 11 imported schistosomiasis cases, all of them were schistosomiasis mansoni cases or schistosomiasis haematobia cases. Conclusions From 2015 to 2017, the reported cases of schistosomiasis are mainly clinically diagnosed cases. Compared with the annual report of the national schistosomiasis control, the number of confirmed cases in NNDRS is seriously missed. Therefore, the endemic provinces should strengthen the supervision on confirmed cases and reporting quality of schistosomiasis cases in accordance with the relevant law and regulation.
