Investigation and analysis of hookworm infection in rural population of Tiantai County

目的通过了解天台县农村人群钩虫病的感染现状,为进一步制定防治策略提供科学依据。方法按照县域范围内东、西、南、北、中5个地理方位随机选取5个行政村作为检测点;选择3周岁以上的常住居民为研究对象,收集每村研究对象的新鲜粪便≥200份,按照WS/T 570—2017《肠道蠕虫检测改良加藤厚涂片法》(Kato-Katz法)检测土源性线虫虫卵。结果共检测5个行政村1013份居民新鲜粪便,39份检出钩虫卵,感染率为3.85%。5个行政村感染率差异有统计学意义(P<0.05),其中南区前杨村感染率最高,为10.95%;西区街一村感染率最低,为0.00%。男女之间钩虫感染率差异无统计学意义(P>0.05);>80岁人群感染率最高,为17.65%。不同职业及不同文化程度人群间土源性线虫感染率差异均有统计学意义(P<0.05)。结论天台县农村人群钩虫感染率较高,且存在区域高发,以高龄、低文化农民人群为主。
