摘要
目的了解和掌握陆丰市重点寄生虫病人群感染状况,为制订防治对策和评价防治效果提供科学依据。方法采集3周岁以上常住居民粪便标本,采用改良加藤厚涂片法(Kato-Katz)一粪三检,检测钩虫、蛔虫、鞭虫等重点寄生虫虫卵,同时采用透明胶纸肛拭子法检测3～12周岁儿童蛲虫卵。结果 5个调查点共粪检1000人,感染人数79人,平均感染率为7.9%,其中钩虫、蛔虫、鞭虫和蛲虫感染率分别为2.6%、0.3%、4.9%和0.2%。检测儿童蛲虫970人,感染率为12.6%;钩虫、蛔虫和鞭虫感染者每克粪便算术平均虫卵数分别为24.2、120和25.7,均为轻度感染;调查点粪检感染率最高的是城东镇,为14.5%,最低是陂洋镇,为5.0%,各调查点感染率差异有统计学意义(χ2=15.86,P<0.005);各年龄组感染率以50～岁组最高(19.8%),60～岁组最低(3.5%);不同文化程度感染率以初中文化水平者最高(10.3%),不同文化程度感染率差异无统计学意义(χ2=5.55,P>0.05)。结论陆丰市重点寄生虫病人群感染情况处于较低水平,其中蛔虫、钩虫和儿童蛲虫感染率明显低于2001-2004年广东省人体重要寄生虫病现状调查水平。
Objective To know about and grasp the population infection status of important parasitic diseases in Lufeng city and provide scientific basis for making the control countermeasures and evaluating the control effect. Methods The stool samples of permanent residents over 3 years old were collected and examined by modified Kato-Katz technique for the eggs of important parasites such as hookworm, ascaris and whipworm. At the meantime, children at 3-12 years old were examined for threadworm by cellophane swab method. Results 1 000 persons took stool examination in 5 survey sites,with 79 being found infected and mean infection rate of 7.9%,of which the infection rates of hookworm,ascaris, whipworm and threadworm were 2.6%,0.3%,4.9% and 0.2%,respectively. 970 children were examined for threadworm,with an infection rate of 12.6%.EPGs of hookworm,ascaris and whipworm infected persons were 24.2,120 and 25.7,respectively,and all were mild infection.The survey site with the highest infection rate by tool examination was Chengdong town （14.5%）,and the site with the lowest infection rate was Beiyang town （5.0%）. Difference between the infection rates in different survey sites was statistically significant（X2=15.86,P0.01）. The highest infection rate for age groups was that of 50-60 years-old group and the lowest was that of over 60 years-old group.The highest infection rate for education levels was that of junior middle school level and difference between the infection rates in different education levels was not statistically significant（X2=5.55,P0.05）. Conclusions The population infection status of important parasitic diseases in Lufeng city was at a lower level. The infection rates of ascaris and hookworm and the threadworm of children were apparently lower than the infection levels in the current-status survey of human important parasitic diseases of Guangdong province in 2001-2004.
