【摘要】：目的了解河南省國家級監(jiān)測點(diǎn)土源性線蟲病的流行動態(tài)。方法 2006-2015年,每年在淮陽縣國家級土源性線蟲病監(jiān)測點(diǎn)收集不少于1 000人份的糞便樣本,采用改良加藤厚涂片法檢查土源性線蟲及其他腸道蠕蟲卵,3~12周歲兒童加做透明膠紙肛拭法檢查蟯蟲卵。此外,每年隨機(jī)抽取10戶家庭,收集其菜地、廁所、庭院和廚房的土壤樣本,用改良飽和硝酸鈉漂浮法檢測土壤蛔蟲卵污染情況。結(jié)果 2006-2015年,共在淮陽縣監(jiān)測點(diǎn)調(diào)查10 419人,檢出5種腸道蠕蟲卵,分別為蛔蟲、鞭蟲、鉤蟲、蟯蟲和東方毛圓線蟲,人群土源性線蟲平均感染率為3.69%,均為輕度感染且存在家庭聚集性。男性和女性土源性線蟲感染率差異無統(tǒng)計學(xué)意義,男、女童蟯蟲感染率差異無統(tǒng)計學(xué)意義(P均0.05)。1~10歲年齡組土源性線蟲、蛔蟲及蟯蟲感染率均最高,其中3~9歲兒童為重點(diǎn)感染人群,蟯蟲為主要感染蟲種。小學(xué)文化程度人群土源性線蟲感染率最高,感染率隨文化程度升高呈遞減趨勢。10年來,河南省國家監(jiān)測點(diǎn)土源性線蟲感染率總體呈逐年下降趨勢。監(jiān)測點(diǎn)土壤中檢出受精蛔蟲卵和未受精蛔蟲卵,但檢出率很低。結(jié)論近10年來河南省國家級監(jiān)測點(diǎn)土源性線蟲感染率呈逐年下降趨勢且維持在較低水平,感染存在家庭聚集性。兒童尤其是3~9歲兒童為重點(diǎn)感染人群,蟯蟲為重點(diǎn)防治蟲種。
[Abstract]:Objective to investigate the epidemic dynamics of soil derived nematode disease in national surveillance sites in Henan Province. Methods from 2006 to 2015, not less than 1,000 fecal samples were collected from national surveillance sites of soil-derived nematode disease in Huaiyang County each year. The egg of Enterobius vermicularis was examined by modified Kato thick smear method. In addition, 10 families were randomly selected each year to collect soil samples from vegetable fields, latrines, yards and kitchens, and to detect the contamination of Ascaris lumbricoides eggs by modified saturated sodium nitrate floatation method. Results from 2006 to 2015, a total of 10 419 people were investigated in Huaiyang County, and 5 kinds of intestinal worm eggs were detected, namely Ascaris lumbricoides, Trichuris trichuris, hookworm, Enterobius vermicularis and Trichoderma orientalis. The average infection rate of soil-derived nematode was 3.69, which was mild infection and family aggregation. There was no significant difference in infection rate between male and female, but there was no significant difference between male and female in Enterobius vermicularis infection (P < 0.05). The infection rate of Ascaris lumbricoides and Enterobius vermicularis was the highest in 10 years old group. Among them, 3 years old children were the main infected population, and Enterobius vermicularis were the main infective species. The infection rate of soil nematode was the highest in the population with primary school education, and the infection rate was decreasing with the increase of education. In the past 10 years, the infection rate of soil derived nematode in the national monitoring sites of Henan Province was decreasing year by year. Fertilized Ascaris lumbricoides and unfertilized Ascaris lumbricoides eggs were detected in the soil of monitoring site, but the detection rate was very low. Conclusion the infection rate of soil-derived nematode in the national surveillance sites of Henan Province has been decreasing year by year and maintained at a low level in recent 10 years. Children, especially children aged 3 to 9, were the focus of infection and pinworm control.
