按照《广西人体重点寄生虫病监测调查实施方案》调查要求,2016—2019年广西百色市对调查点人群开展人体土源性线虫病（包括钩虫病、蛔虫病、鞭虫病、蛲虫病）和华支睾吸虫病的调查。每个调查点整群抽取3周岁以上常住居民200 人,采集粪便标本,采用改良加藤厚涂片法（Kato-Katz）,一粪二检,镜检土源性线虫、华支睾吸虫等虫卵并计数;土源性线虫调查点加做钩蚴试管滤纸培养法并鉴定粪样中的十二指肠钩虫和美洲钩虫;3~12岁儿童采用透明胶纸肛拭法查蛲虫卵。结果显示,百色市2016—2019年共开展人体寄生虫病调查14 524人次,感染人数为1 464人,总感染率为10.08%;2018年感染率最高,为16.72%（508/3039）,2016年感染率最低,为6.79%（283/4 168）。华支睾吸虫感染率最高,为4.96%（721/14 524）,其次为钩虫3.48%（80/14 524）。男性人体寄生虫感染率为6.94%（452/14 524）,女性为12.63%（1 012/14 524）（P < 0.01）;13~20岁年龄组、常住地为农村、职业为农民、文化水平为文盲、田阳区的人群感染率较高,分别为21.46%（362/1 268）、 29.58%（1 039/3 512）、13.39%（641/4 787）、19.96%（641/3 211）、13.50%（561/4 155）。4年内共检查2 485名儿童,蛲虫感染者166例,感染率为6.68%;其中7岁组儿童感染率最高,为10.45%（23/220）;男童感染率为5.83%（69/1 184）,女童感染率为7.46%（97/1 301）。2016—2019年百色市人体寄生虫感染率总体呈先上升后降低趋势,华支睾吸虫感染率较高,土源性线虫感染以钩虫感染率较高。应加强对13~20岁年龄组、农村、农民、文盲、田阳区等重点人群的治疗与宣传教育工作。

In accordance with the Implementation Plan for Surveillance and Investigation of Key Human Parasitic Diseases in Guangxi, a survey on human soil-borne nematodiasis (including hookworm disease, ascariasis, whipworm disease, pinworm disease) and clonorchiasis was performed in Baise City, Guanxi, from 2016 to 2019. Stool samples were collected from 200 residents over 3 years old at each site, and examined with modified Kato-Katz thick smear method for the eggs of soil-borne nematodes and Clonorchis sinensis and counted. Hookworm species were identified using larva test-tube filter paper culture method for Ancylostoma duodenale and Ancylostoma americana; Enterobius eggs were examined with cellophane anal swab for children aged 3-12 years. The survey of human parasitic diseases were carried out for 14 524 person-times in the city in 2016—2019. The results showed that a total of 1 464 persons were found infected, with a infection rate of 10.08%. The infection rate was highest in 2018 (16.72%, 508/3 039), and lowest in 2016 (6.79%, 283/4 168). The infection rate was highest ofC. sinensis (4.96%, 721/14 524) followed by hookworms (3.48%, 80/14 524). The infection rate was 6.94% (452/14 524) in males and 12.63% (1 012/14 524) in females (P < 0.01). The infection rate was high in populations aged 13-20 years, residing in rural areas, with an occupation of farmers, and having an education level of illiteracy, and in Tianyang District, which were 21.46% (362/1 268), 29.58% (1 039/3 512), 13.39% (641/4 787), 19.96% (641/3 211) and 13.50% (561/4 155), respectively. A total of 2 485 children were examined during the 4 years, of them 166 were infected with Enterobius vermicularis (6.68%, 166), and the highest rate was found in 7-year-old children (10.45%, 23/220). The infection rate was 5.83% (69/1 184) in boys and 7.46% (97/1 301) in girls. The results indicate that the infection rate of human parasites in Baise showed a trend of increase followed by a decrease during 2016—2019. The infection rate ofC. sinensis was relatively high, but the infection of soil-borne nematode was predominated by hookworm infection. It is necessary to strengthen the treatment, and health education in the key populations aged 13-20 years, residing in rural areas, with an occupation of farmers, and having an education level of illiteracy, and in Tianyang District.
