title: [Analysis of epidemiological characteristics of advanced schistosomiasis in Hu-nan province, 2012].
abstract: 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.
  
  
  METHODS
  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 Hunan Province, and among them, 4 112 patients were male (71.86%), and 1610 were female (28.14%). Totally 5311 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 patients, 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%).
  
  
  CONCLUSIONS
  The prevalence rate of advanced schistosomiasis is relatively stable in Hunan Province, and the age of the patients showed an old aging trend. The salvation of advanced schistosomiasis patients in non-endemic areas should be strengthened.
