ABSTRACT

Objective To evaluate the cost-effectiveness of comprehensive schistosomiasis control measures with focus on total removal of cattle and sheep in Juanshan District,Yueyang City.Methods The schistosome infection status of human,cat-tle,sheep and Oncomelania hupensis snails and costs of control measures were gathered during the period of 2006 to 2016.The costs for different periods and cost-effectiveness ratios were calculated.Results The prevalence of schistosome infection in resi-dents in the pilot villages decreased from 3.44% in 2006 to 0 in 2016.The annual costs of schistosomiasis prevention and control were 4 708 500 yuan from 2006 to 2008,5 094 700 yuan from 2009 to 2012 and 9 522 700 yuan from 2013 to 2016.The cost-ef-fectiveness analysis showed that the average annual cost of reduction in the residents'infection rate by 1% were 79 500 yuan from 2006 to 2008,101 200 yuan from 2009 to 2012,and 95 200 yuan from 2013 to 2016,respectively.
