[Effect of integrated measures on schistosomiasis transmission--interruption in hilly areas].

ABSTRACT

OBJECTIVE: To evaluate the effect of control integrative measures which persist in snail eradication and chemotherapy on schistosomiasis transmission-interruption in hilly areas. METHODS: The data of integrated control and endemic situation of schistosomiasis from 2004 to 2014 were collected, and the control effect of integrated measures was evaluated. RESULTS: From 2004 to 2014, both the Oncomelania hupensis snail area and density of living snails of Jurong City were reduced from 43.13 hm2 and 1.48 snails/0.1 m2 to 0; the residents' seropositive rate declined continuously; the residents' and students' awareness rates on schistosomiasis control were increased from 88.43% and 82.04% to 92.56% and 95.74% respectively; the snail area was significantly negatively correlated with the coverage rate of snail control (r = -0.864, P < 0.05). CONCLUSIONS: In the hilly areas, the schistosomiasis control integrated measures which persist in snail eradication and chemotherapy could control the endemic situation rapidly and steadily, accelerating to achieve the goal of schistosomiasis transmission-interruption.
