title: [Performance evaluation of small snail control projects in Hubei Province in 2009 and 2010].
abstract: OBJECTIVE
  To evaluate the performance of small Oncomelania snail control projects in Hubei Province in 2009 and 2010, so as to explore the best snail control project in different areas.
  
  
  METHODS
  The expense-effect, expense-efficiency and cost-utility analyses were carried out to analyze the small snail control projects with reference to the relevant schistosomiasis japonica prevention and control index system.
  
  
  RESULTS
  The coverage rate of snail control was 40.15%, the decrease rate of the snail areas was 32.86%, the unit cost for the snail control was 0.39 Yuan/m2, the cost of reducing 1% of the snail area was 67.34 ten thousand Yuan, the total benefit was 15 554.14 ten thousand Yuan, the ratio of cost to benefit was 7.03, the net benefit was 13 341.44 ten thousand Yuan, and the ratio of cost to net benefit was 6.03, and the investment ratio was 1 : 2.11 in the 183 small snail control projects.
  
  
  CONCLUSIONS
  There is an obvious and respectable short-period effect of the small snail control projects.
