The incidence in 2007 was 59.17 / 100 000, the incidence in 2008 was 34.88 / 100 000 and the incidence in 2009 was 145.60 / 100 000 (P <0.01). The average annual incidence rate (/ 100,000) from 2007 to 2009 was 123.07 in the county town and 72.71 in the rural township (P <0.01), 101.61 for males and 57.86 for females (P <0.01), and 447.601 and 353.57 for 0-5 years , 2 065.67,1 057.84,567.00,316.07, 6 ~ 15 years old was 23.33 (P <0.01).
