[Sampling survey on schistosomiasis in Jingzhou City in 2006].
A survey on schistosomiasis conducted in sampled 453 out of 1971 villages in Jingzhou City in the year of 2006. Miracidia hatching test demonstrated that the prevalence in human population was 3.9% (12,006/310,232), with sporadic cases of acute schistosomiasis, and the prevalence in cattle was 10.2% (270/2,651). The mean density of living snails was 0.67/0.11 m2 (1,988/1,054,597) with a density of infected snails of 0.001 9/0.11 m2 (1,988/713,486). In comparison to those of 2004, prevalence in humans decreased by 40.0%, prevalence in cattle increased by 22.3%; the snail-ridden area increased by 4.0%, but the mean density of living snails increased by 68.5% and the infected snail density increased by 18.8% with a decrease of 36.4% in snail infection rate. Consequently, there is an urgent need in controlling schistosome infection in cattle.
