Routine serologic testing of pregnant women in a predominantly Hispanic population at the Los Angeles County Medical Center revealed that 8 of 2,000 were positive for hepatitis B surface antigen (HBSAg). Only two of the eight women had a risk factor as currently defined by the Centers for Disease Control. Screening of all pregnant women is necessary to identify those HBSAg-positive women capable of transmitting the hepatitis B virus to their infants. All the other obstetric surveys reviewed support the need to screen obstetric patients and to provide immunoprophylaxis to the infants at risk of perinatal infection. This policy is necessary to prevent perinatal transmission of hepatitis B virus and is cost effective.
在洛杉矶县医疗中心对以西班牙裔为主的人群中的孕妇进行的常规血清学检测显示，2000名孕妇中有8名乙肝表面抗原（HBSAg）呈阳性。这8名女性中只有两人有目前疾病控制中心定义的风险因素。对所有孕妇进行筛查，以识别那些能够将乙肝病毒传播给婴儿的HBSAg阳性女性是必要的。所有其他经审查的产科调查都支持对产科患者进行筛查，并为有围产期感染风险的婴儿提供免疫预防的必要性。这项政策对于预防乙肝病毒的围产期传播是必要的，而且具有成本效益。
