三明地区中老年人钩虫感染流行特征调查分析

Investigation and Analysis on the Epidemiological Characteristics of Hookworm Infection in Middle-aged and Elderly People in Sanming Area

目的调查和分析三明地区中老年人钩虫感染的流行特征,为制定针对性的预防和控制策略提供依据。方法采用Kato-Katz法对粪便的钩虫卵数进行准确的计数统计,在对钩虫虫种进行鉴定时选用试管滤纸培养法。结果共调查了4个村的200名中老年人,结果检出54名钩虫感染者,平均感染率为27.00%。改水和改厕较差的村庄钩虫感染率较高,有统计学意义(P<0.05)。对感染者的分析表明,在性别上没有明显差异,但在年龄上有明显差异(P<0.05)。随着文化程度的提高,感染率也有所下降,差异有统计学意义(P<0.05)。结论中老年人感染钩虫的概率较高,需要加强卫生设施建设和改善卫生条件。

Objective This study aims to investigate and analyze the epidemiological characteristics of hookworm infection in middle-aged and elderly people in Sanming area,providing a basis for formulating targeted prevention and control strategies.Methods In this study,the Kato Katz method was used to accurately count and count the number of hookworm eggs in feces.When identifying hookworm species,the test tube filter paper culture method was used.Results A total of 200 middle-aged and elderly people from 4 villages were surveyed.The results showed that the average infection rate of 54 hookworm infected individuals was 27.00%.The probability of hookworm infec-tion is higher in villages with poor water and toilet improvements,with statistical significance(P<0.05).The analysis of infected individuals showed that there was no significant difference in gender,but there was a significant difference in age(P<0.05).As the level of education increases,the infection rate also decreases,with a statistically significant difference(P<0.05).Conclusion The probability of hookworm infection among middle-aged and elderly people is high,and it is necessary to strengthen the construction of sanitation facilities and improve hygiene conditions.
