摘要:

为调查与了解上海市崇明区广州管圆线虫病潜在传播风险因素,为岛内广州管圆线虫病传播风险监测与评估提供参考。于2023年4—10月在上海市崇明区开展福寿螺分布调查,并重点选取岛内沿长江水域以南6个福寿螺分布面积较大的乡镇作为重点调查区域开展病例回顾性调查、转续宿主、野外环境、市售螺类情况和居民问卷现场调查,同时选取1个具有代表性的乡镇采用夹夜法开展野鼠感染性调查。结果显示,崇明区共辖乡镇18个,其中15个乡镇发现福寿螺分布。在6个重点调查乡镇共调查了60处野外环境,捕获福寿螺1 228只;共计18处农贸市场和餐饮店完成市售螺类调查,共采集到中华圆田螺1 200只、铜锈环棱螺12件,未发现福寿螺和褐云玛瑙螺,采集淡水鱼、河虾、河蟹等转续宿主共计257件,均未发现广州管圆线虫感染。在港西镇双津村捕捉到野鼠105只,未发现广州管圆线虫成虫。在6个乡镇共发放调查问卷300份,回收率100%,人群知晓率为22%(66/300),以20~39岁年龄组(30.37%,41/135)、城市居民(32.65%,32/98)和大专及以上人群(30.56%,44/144)知晓率较高(χ2 = 13.193、16.624、11.923,P < 0.05)。在食用凉拌或酱爆螺蛳、食用生或半生螺肉、食用醉蟹和(或)醉虾及蟹糊、直接饮用过滤水或自来水、接触福寿螺或蛞蝓等五项生活习惯方面,有一种及以上者占65.99%(198/300),其中以食用醉蟹和(或)醉虾及蟹糊最高(11.67%,35/300),此外有购买或食用福寿螺倾向占比3.67%(11/300)。崇明区广州管圆线虫病传播链较完整,存在输入或本地传播潜在风险,建议强化“人-动物-环境”动态系统风险监测,并做好突发事件应对准备。

Abstract:

To investigate the potential risk factors for angiostrongyliasis transmission across Chongming District of Shanghai Municipality, so as to provide insights into monitoring and assessment of angiostrongyliasis transmission risk in this island. A survey was conducted on Pomacea snail distribution across Chongming District of Shanghai Municipality, from April to October 2023, and six high-risk townships with relatively large areas of Pomacea snail-infested habitats south of the Yangtze River in the island were selected for a retrospective survey of angiostrongyliasis cases, survey of paratenic hosts, wild environments and market-sold snails, and field questionnaire surveys among residents. In addition, wild mice were captured with a trapping method at night from a representative township for detection of Angiostrongylus cantonensis infections. There were 15 out of 18 townships detected with Pomacea snails in Chongming District. A total of 60 wild environments were investigated in 6 high-risk townships, with 1 228 Pomacea snails captured. A total of 1 200 Cipangopaludina cathayensis and 12 Bellamya aeruginosa snails were sampled from 18 farmers’ markets and restaurants, with no Pomacea snails or Lissachatina fulica found, and a total of 257 paratenic hosts (freshwater fish, river shrimp, and river crabs) were collected, with no A. cantonensis infections detected. A total of 105 wild mice were captured from Shuangjin Village, Gangxi Township, with no adult A. cantonensis worms identified. A total of 300 questionnaires were allocated in 6 townships, with a 100% recovery rate, and the awareness rate of angiostrongyliasis control knowledge was 22% (66/300), with a relatively high awareness rate among respondents at ages of 20 to 39 years (30.37%, 41/135), urban residents (32.65%, 32/98), and respondents with an educational level of junior college and above (30.56%, 44/144) (χ2 = 13.193, 16.624, 11.923, P < 0.05). There were 65.99% (198/300) of respondents with at least one of the five living habits of eating raw snails or snails stewed in soy sauce, eating raw or half-cooked snail meat, eating drunk crabs and/or drunk shrimps and crab paste, drinking filtered water or tap water directly, and contact with Pomacea snails or slugs, with the highest proportion for eating drunk crabs and/or drunk shrimps and crab paste (11.67%, 35/300). In addition, 3.67% (11/300) of respondents had a tendency to purchase or consume Pomacea snails. There is a relatively complete transmission chain for angiostrongy-liasis throughout Chongming District, with potential risks for both imported and local transmission. It is recommended to reinforce the dynamic systemic risk monitoring of the “human-animal-environment” and respond to emergency events.
