[Longitudinal observation on schistosomiasis control effect of human-cattle synchronous chemotherapy].

The annual reports of human-cattle synchronous chemotherapy from 1992 to 2008 were collected and analyzed, and its effect on schistosomiasis control was evaluated. The results showed that human and cattle infection rates decreased by 72.37% (chi2 = 9.85, P < 0.01) and 65.18% (chi2 = 5.63, P < 0.01), respectively. The snail infection rate and the density of infected snail decreased by 63.64% and 69.44%, respectively. It is concluded that schistosomiasis in Qianjiang City has been effectively controlled after the implementation of human-cattle synchronous chemotherapy for 16 years.
