Summary:To analyze the snail situation in schistosomiasis surveillance sites in Hubei Province from 2009 to 2014. From 2009 to 2014, 207 schistosomiasis endemic villages from 13 cities were selected as the surveillance sites in Hubei Province, where the surveillance of snail situation was performed, and the data about the indexes of snail situation during the 6 years were collected and analyzed statistically. From 2009 to 2014, totally 80 963.47 hm of snail areas were investigated, and 45 309.77 hm of area with snails as well as 364.93 hm of area with infected snails were found out, and 1 646 125 snails were captured. In the 207 surveillance sites, the density of living snails was reduced from 0.493 3 snail/0.1 m in 2009 to 0.339 3 snail/0.1 m in 2014, with a decline rate of 31.22%; the density of infected snails was reduced from 0.000 7 snail/0.1 m in 2009 to 0 in 2014; the infection rate of snails was reduced from 0.14% in 2009 to 0 in 2014. The infection rates of snails in the third-rank villages, endemic areas in
