Abstract:
Objective To explore how to control schistosomiasis at the presence of snails in lake marshland. Methods From March 1st to October 31st every year, 2000-2002- the measure of "marshland isolation and farming prohibition" was carried out. Local residents and cattle were examined and treated for schistosomiasis. Results The infections rate of schistosomiasis in surveillance spots decreased from 2.66% (1999) to 1.66% (2002). The infections rate was 0.57% (5/ 871 ) in the township. There were no acute schislosomiasis cases and new patients. The rate of schistosomiasis of cattle decreased from 4. 90% (1999) to 0. 14% . and there was no new calf under two years of age infected. The rale of infected snails decreased from 1. 450% to 0. 005% , and the density of positive snails from 0. 014 8 snail /0. 1 m2 to 0. 000 11 snail/0. 1 m2. Conclusion The measure, mainly including "marshland isolation and farming prohibition", can control schistosomiasis prevalence even at the presence of snails in lake marshland.
