[Investigation on current schistosomiasis cases in Sichuan Province]

To understand the status of current schistosomiasis patients after the interruption of schistosomiasis transmission in Sichuan Province, so as to provide the reference for the development of specific rescue and treatment schemes and the implementation of dynamic management of the patients.

The information of registered schistosomiasis patients in disease control and prevention institutions and medical institutions were reviewed in all schistosomiasis-endemic counties (districts) across Sichuan Province in 2018, and the data of all newly discovered schistosomiasis patients were collected and analyzed.

A total of 1 558 current schistosomiasis cases were diagnosed in 11 endemic cities (prefectures) across Sichuan Province, and all were advanced cases. Megalosplenia and ascites were the predominant types of advanced schistosomiasis cases, and no age- (χ² = 16.723, P > 0.05) or gender-specific difference (χ² = 2.493, P > 0.05) was seen in the clinical types of current schistosomiasis cases. There were 9.3% of current schistosomiasis patients from poor households. There was a tendency towards a decline in the number of advanced schistosomiasis cases since 2012, and the number of schistosomiasis cases in 2018 reduced by 17.8% as compared to that in 2012.

Currently, all current schistosomiasis patients are advanced cases in Sichuan Province. In the future, multidisciplinary collaboration should be implemented to search for a feasible financial subsidy pattern and establish an effective care system for advanced schistosomiasis patients.
