This study evaluated cost-effectiveness of a comprehensive schistosomiasis control program (2003\u20132006). The comprehensive control program was implemented in Zhangjia and Jianwu (cases); while standard interventions continued in Koutou and Xiajia (controls). Incurred costs were documented and the schistosomiasis comprehensive impact index (SCI) and cost-effectiveness ratio (Comprehensive Control Program Cost\/SCI) were applied. In 2003, prevalence of Schistosoma japonicum infection was 11.3% (Zhangjia), 6.7% (Jianwu), 6.5% (Koutou), and 8.0% (Xiajia). In 2006, the comprehensive control program in Zhangjia and Jianwu reduced infection to 1.6% and 0.6%, respectively; while Koutou and Xiajia had a schistosomiasis prevalence of 3.2% and 13.0%, respectively.  The year-by-year SCIs in Zhangjia were 0.28, 105.25, and 47.58, with an overall increase in cost-effectiveness ratio of 374.9%\u2013544.8%. The SCIs in Jianwu were 16.21, 52.95, and 149.58, with increase in cost-effectiveness of 226.7%\u20131,149.4%. Investment in Koutou and Xiajia remained static (US$10,000 unit cost). The comprehensive control program implemented in the two case villages reduced median prevalence of schistosomiasis  8.5-fold. Further, the cost effectiveness ratio demonstrated that the comprehensive control program was 170% (Zhangjia) and 922.7% (Jianwu) more cost-effective. This work clearly shows the improvements in both cost and disease prevention effectiveness that  a comprehensive control program-approach has on schistosomiasis infection prevalence.<\/jats:p>","DOI":"10.3390\/ijerph10126409","type":"journal-article","created":{"date-parts":[[2013,11,28]],"date-time":"2013-11-28T12:06:47Z","timestamp":1385640407000},"page":"6409-6421","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Impact and Cost-Effectiveness of a Comprehensive Schistosomiasis japonica Control Program in the Poyang Lake Region of China"],"prefix":"10.3390","volume":"10","author":[{"given":"Qing","family":"Yu","sequence":"first","affiliation":[{"name":"Department of Schistosomiasis, National Institute of Parasitic Diseases, Chinese Center for Disease Control and Prevention, 207 Rui Jin Er Road, Shanghai 200025, China"},{"name":"World Health Organization Collaborating Center for Malaria, Schistosomiasis, and Filariasis\u2014Key Laboratory of Parasite and Vector Biology, Ministry of Health, 207 Rui Jin Er Road, Shanghai 200025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Geng-Ming","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, School of Public Health, Fudan University, 130 Dong An Road, Shanghai 200032, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xian-Lin","family":"Hong","sequence":"additional","affiliation":[{"name":"Jingxian Schistosomiasis Control Station, JingXian 331700, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric","family":"Lutz","sequence":"additional","affiliation":[{"name":"Environmental and Occupational Health Section, Division of Community, Environment, and Policy, Mel and Enid Zuckerman College of Public Health, University of Arizona, 1656 E.
