目的了解高州市2011~2014年土源性线虫病流行变化情况,探讨其影响因素,为土源性线虫病的防控提供科学依据。方法采用改良加藤厚涂片法,对监测点常住居民土源性线虫感染进行调查,采用透明胶纸肛拭法对监测点学校6~12岁部分学生进行蛲虫卵检查。结果 4年共调查3 962人,感染者493人,平均感染率为12.44%,共检出4种寄生虫,感染以钩虫为主,未见蛔虫感染;2011年最低(8.72%),2014年最高(15.24%),感染率有呈上升趋势,各年间感染率差异有统计学意义(P<0.01)。结论高州市土源性线虫感染率近四年呈上升趋势,因此需加大经费投入,加大防控知识宣传,进步提高民众防控知识和自保护意识。
Objective To understand the epidemiological changes of soil-borne nematodes from 2011 to 2014 in Gaozhou, and to explore the influencing factors, so as to provide a scientific basis for the prevention and control of soil-borne nematode diseases. Methods The modified Kato thick smear method was used to investigate the infection of soil-borne nematodes among the resident population in the monitoring sites. Oviparous eggs of some 6-12-year-old students at the monitoring point were inspected with the transparent adhesive tape anal swab method. Results A total of 3 962 people were surveyed in 4 years, 493 were infected with an average infection rate of 12.44%. A total of 4 parasites were detected. The infection was mainly hookworm, with no roundworm infection. The lowest in 2011 (8.22%), 2014 The highest infection rate (15.24%) showed an upward trend with a significant difference in infection rates (P <0.01). Conclusion The infection rate of soil-borne nematodes in Gaozhou is on the rise in recent four years. Therefore, it is necessary to increase funding, intensify the prevention and control of knowledge and publicity, and improve people’s awareness of prevention and control and self-protection.
