The annual infection rate was significantly different (χ ~ 2 = 45.607, P <0.05 ). There was no significant difference in infection rates between different genders (χ ~ 2 = 0.063, P> 0.05). The infection rates in different quarters were significantly different (χ ~ 2 = 9.399, P <0.05) (Χ ~ 2 = 16.790, P <0.05).
