【摘要】 目的:了解HBV的传播与感染途径,为预防乙型肝炎提供依据。方法:不同频率聚餐人群为研究对象,采集血液和唾液为标本,用ELISA法检测血液HBV-M、PCR法检测唾液HBVDNA。结果:各组间HBV-M和HBV DNA阳性结果的差别具有统计学意义(P<0.001),阳性率与聚餐频率呈正相相关。结论:唾液中存在HBV,HBV能够通过唾液途径而传播。更多还原

【Abstract】 Objective:To know the relation between different frequency of dining out and infection of HBV.Methods:Made the people with different frequency dining out as study objects and gathered the blood and saliva for examination.HBV-M in blood was detected by ELISA and HBV DNA in saliva was detected by PCR.Results:The differences of the positive results of HBV-M and HBV DNA in every group had statistical meaning(P<0.05～0.01). Conclusion:HBV existed in saliva and saliva might be a spreading way of HBV.High frequency of dining out can be an important spreading way of HBV.更多还原
