摘　　要：目的了解南通市戊型肝炎病毒(HEV)在饮服行业从业人员中新近隐性感染情况,为预防和控制戊型肝炎的流行提供基础数据。方法采集饮服行业从业人员血液样品进行谷丙转氨酶(ALT)和HEV-IgM抗体(ELISA法)检测,HEV-IgM抗体阳性者再检测HEV-IgG抗体(ELISA法),并进行统计学分析。结果35331人份血液样品,HEVIgM抗体阳性14人,阳性率为3.96/万,其中男性阳性率为5.89/万(8/13576)、女性为2.76/万(6/21755),差异无统计学意义(χ~2=2.0739,P=0.1498)。新近隐性感染12人,感染率3.40/万。结论南通市饮服行业从业人员存在HEV新近隐性感染现象,应加强饮服行业从业人员HEV隐性感染监测,防止HEV的传播与戊型肝炎的流行。Objective To acquire HEV newly subclinical infection situation in the group of catering service and to gather data for prevention and control of HEV prevalence in Nantong.

While the male positive rate is 5. 89/10 000（8/13 576）,and the female positive rate is2. 76/10 000（6/21 755）. The gender disparity of positive rate is statistically different（χ2= 2. 0 739,P = 0. 1 498）. 12 were newly inapparently infected with an infection rate 3. 40/10 000.
