[Epidemiological investigation on confirmed cases of schistosomiasis in Hubei Province].

Objective: To grasp the distribution and epidemiology of confirmed cases of schistosomiasis in Hubei Province, so as to provide the evidence for promoting the prevention and control work.

Methods: The confirmed cases of schistosomiasis in Hubei Province from 2010 to 2014 were epidemiologically investigated, and the prevalence characteristics and main influencing factors were analyzed.

Results: A total of 10 102 confirmed cases from 2010 to 2014 were surveyed. There were 1 062 local infected patients, accounting for 10.51% and including 354 repeated infections and 17 newly infected. There were 290 foreigninfected patients, accounting for 2.87%, with 206 repeated infection cases and 84 newly infected. There were 8 750 historical patients, including 2 229 patients who leaked the former schistosomiasis investigations, accounting for 22.06%; 570 patients missed treatment, accounting for 5.64%; 3 640 patients were treated with non-standard therapy, accounting for 36.03%; 2 311 patients were treated with poor medication efficacy, accounting for 22.88%. The multivariate non-conditional Logistic regression, targeting at confirmed cases in 2014, showed that, for the leaking investigations, the potential risk factors included the age, educational level, and latrine renovation (＞0, ＞1), the protective factors were the times of previous treatment, cattle feeding in villager team, and snails in surroundings (＜0, ＜1); for the treatment-missing, the age, educational level, snails in the surroundings of residence were risk factors (＜0, ＜1); for the substandard treatment, the risk factors included the occupation and snails in the surroundings of residence (＞0, ＞1), and the educational level and snails in the own field were protective factors (＜0, ＜1).

Conclusions: The epidemiological investigation on the confirmed cases of schistosomiasis could grasp the epidemic factors so as to improve the management and carry out the scientific control.
