Objective To understand the epidemiological characteristics of patients with advanced schistosomiasis in Hunan Province,so as to provide the evidence for formulating the advanced schistosomiasis prevention strategies and measures. Meth-ods The data of advanced schistosomiasis patients were collected and analyzed retrospectively with the cross section research method and description method in Hunan Province,2012. Results There were 5 722 advanced schistosomiasis patients in Hu-nan Province,and among them,4 112 patients were male(71.86%),and 1 610 were female(28.14%). Totally 5 311 patients came from the schistosomiasis endemic areas(92.82%)and 411 patients from non-schistosomiasis endemic areas(7.18%). The prevalence rate of advanced schistosomiasis was 8.46/10 000. The mean age of advanced schistosomiasis patients was 60.30 ± 11.63 years,and the youngest was 17 years old and the oldest 92 years old. In the age composition of advanced schistosomiasis pa-tients,the greatest number of cases was in the 60-70 years age group (32.72%). There were 3 595 cases of ascites type (62.83%),2107 cases of splenomegaly type(36.82%),11 cases of dwarf type(0.16%),and 11 cases of colon proliferation type (0.35%). Conclusion The prevalence rate of advanced schistosomiasis is relatively stable in Hunan Province,and the age of the patients showed an old aging trend.
