Abstract:

Objective  To analyze the endemic changes of schistosomiasis in Hunan Province from 2002 to 2015 for following evidence in prevention and control of this prevalence. Methods  Annual data reported schistosomiasis prevention and control in Hunan province were collected from 2002 to 2015, and descriptive statistics was used to quantitatively describe the changes of endemic schistosomiasis. Results  By 2015, all regions in our province reached the criteria of transmission control, and 15 cities(including administrative districts, counties, and farms) were up to the criteria of transmission interruption. The number of estimated schistosomiasis cases and reported acute infections was decreased to 27 900 and zero in 2015 from 206 400 and 197 in 2002, with a decrease of 86.48%, and 100%, respectively. Infection in farm cattle was reduced to 285 capita in 2015 from 3 091 capita in 2002, with a fall of 92.69%. Snail ridden areas started to rebound in 2003, and to 175953.31 hm2  in 2015. Conclusion  Endemic schistosomiasis appears to significantly fall in Hunan province from 2002 through 2015. However, prevention of snail spreading and acute infection with schistosomiasis remains primary yet difficult in current and following tasks.
