对４１４名煤矿职工甲、乙、丙型肝炎的流行病学调查显示：该人群病毒性肝炎现患率为１２％，其中甲肝占４０％、乙肝４０％、丙肝２０％；甲肝感染率为９６３８％、乙肝表面抗原阳性率７２５％、乙肝总感染率５３１４％、丙肝感染率２９％。经逐步回归分析显示：乙肝表面抗原携带的危险因素为输血与使用公用水杯，乙肝感染危险因素为工龄及使用公用毛巾、浴巾、丙肝危险因素为半年内曾拔牙或手术。本调查结果可为煤矿肝炎的防治工作提供科学依据。
Epidemiological investigation of 414 coal mine workers A, B and C showed that the prevalence of viral hepatitis in this population was 1.2%, of which 40% were hepatitis A, 40% hepatitis B and 20% hepatitis C, and the rate of hepatitis A infection was 96 38%, hepatitis B surface antigen positive rate 7 25%, total hepatitis B infection rate 53 14%, hepatitis C infection rate 2 9%. The stepwise regression analysis showed that the risk factors for HBsAg were blood transfusion and use of common drinking cups. The risk factors for HBV infection were length of service and the use of public towels, bath towels and hepatitis C risk factors were those who had had tooth extraction or surgery within six months. The results of this survey can provide a scientific basis for prevention and control of coal mine hepatitis.
