Results A total of 4 483 people were surveyed, 381 eggs were detected and the average infection rate was 8.50%. The infection rates in 2008, 2009, 2010 and 2011 were 14.09%, 10.57%, 4.68% and 4.40% respectively, The difference in the first 3 years was statistically significant and was controlled in 2010 and 2011 (χ2 = 6.68, P <0.05, χ2 = 29.31, P <0.01, χ2 = 0.09, P> 0.05) , Respectively. The infection rates in 5 orientations were 3.68%, 6.98%, 6.35%, 10.51% and 14.54%, respectively. The difference was statistically significant.
