目的 了解抗洪部队血吸虫感染状况,及时根治疾病,探索大规模快速疾病普查方法。方法 1998年9月10～24日分两批分别对参加荆江段和武汉段抗洪抢险的两支空军部队进行血吸虫病普查,普查方法采用经皮试初筛后ELISA法确认,或直接经ELISA法确认两种方法。结果 血吸虫感染皮试阳性率为18.4％,第一次调查血吸虫感染阳性率为1.4％,第二次为0.6％;荆江抗洪部队血吸虫感染阳性率为1.1％,武汉抗洪部队阳性率为0.3％,差别有显著性(P<0.05)。服预防性药物者感染率较低,其中吡喹酮预防效果优于菁蒿琥酯片。结论血吸虫感染与疫区作业有关,预防性服药可以降低感染率。
Objective To understand the status of schistosomiasis infection in flood fighting forces, to cure the disease in time and to explore the method of large-scale rapid disease screening. Methods From September 10 to September 24, 1998, two batches of air force units participating in Jingjiang section and Wuhan section were respectively surveyed by schistosomiasis in two batches. The screening method was confirmed by ELISA after transdermal screening, or directly by ELISA Confirm two methods. Results The positive rate of schistosomiasis skin test was 18.4%. The positive rate of schistosomiasis infection was 1.4% and the second was 0.6%. The positive rate of schistosomiasis infection was 1.1% in Jingjiang Flood Control Corps and 0.3% in Wuhan Flood Control Corps. The difference was significant (P <0.05). Preventive drug taking the infection rate is low, of which praziquantel prevention effect is better than artesunate tablets. Conclusions Schistosoma infection is related to the operation of epidemic area. Prophylactic medication can reduce the infection rate.
