  1. Spring-early summer, April-end of June; Late summer-autumn, end of July-October; (pos/ex), number of positive/number of examined; 95 % CI, confidence interval; χ 2, goodness-of-fit test; P, significance level
  2. aFisher’s exact test was used to compare prevalence between spring and autumn because the condition of χ 2 goodness-of-fit test was not fulfilled
