目的了解上海市金山区外来务工人员的血吸虫感染及预防知识知晓情况,为传播阻断地区开展外来务工人员防治工作提供科学依据。方法对来自血吸虫病流行省份的外来务工人员和当地居民采用间接血凝法(IHA)筛查,血检阳性者采用改良加藤法和孵化法联合查病,问卷调查血吸虫病知晓和行为情况。结果共调查579人,其中来自流行省份的外来务工人员348人,本地居民231人,男性占72.0%,女性占28.0%。外来务工人员以来自安徽省的最多,占36.2%,年龄上以20~29岁最多,占56.0%,受教育程度高中及以上占56.6%。在外来务工人员中查出血清学阳性4人,阳性率为1.15%;查出粪检阳性1人,推算血吸虫感染率为0.29%,当地居民未查到血清学阳性者和病人。外来务工人员在户籍地愿接受血吸虫病检查和治疗的占79.9%,在务工地愿接受血吸虫病检查和治疗的占84.8%,在务工地自费检查和治疗血吸虫病的占48.6%。外来务工人员的血吸虫病知识知晓情况普遍较差,部分人员存在就诊和服药的不正确行为。结论来自流行省份的外来务工人员中存在血吸虫感染者,其血吸虫病预防知识知晓程度较低,增加了当地血吸虫病传播风险。
Objective To understand the status of schistosomiasis infection and prevention knowledge of migrant workers in Jinshan District of Shanghai and to provide a scientific basis for the prevention and treatment of migrant workers in the area of blocking transmission. Methods Indirect hemagglutination (IHA) screening was carried out among migrant workers and local residents from endemic provinces of schistosomiasis. The positive persons were tested with improved Kato’s method and hatching method, and the questionnaire was used to investigate the knowledge and behavior of schistosomiasis. Results A total of 579 people were investigated, including 348 migrant workers from popular provinces, 231 local residents, accounting for 72.0% of men and 28.0% of women. Migrant workers from Anhui Province accounted for the largest, accounting for 36.2% of the age of 20 to 29 years old, accounting for 56.0%, 56.6% of high school education and above. Among migrant workers, 4 were found serologically positive, with a positive rate of 1.15%. One person was found to have a positive stool test. The infection rate of schistosomiasis was 0.29%. Local seropositive patients and patients were not found. Migrant workers are willing to accept the examination and treatment of schistosomiasis in the domicile account for 79.9%, in the construction site would like to accept the examination and treatment of schistosomiasis accounted for 84.8%, at the construction site to check and treat schistosomiasis at their own expense accounted for 48.6%. Migrant workers knowledge of schistosomiasis generally poor, some staff presence and medication taking the wrong behavior. Conclusions Schistosoma infection exists among migrant workers from popular provinces, and their awareness of schistosomiasis prevention is low, which increases the risk of local schistosomiasis transmission.
