高危行为人群5型病毒性肝炎感染因素研究

1994年 10月～ 1996年 12月 ,对归国劳务人员 119名、卖淫妇女 55名、医务人员 86名、性病患者 88名、有偿供血者 88名 ,进行了 HAV、HBV、HCV、HDV、HEV感染状况调查。5组人群 HAV感染率均在 83%以上 ,医务人员 HBV感染率 ( 53.4 9% )与对照组 ( 30 .4 3% )有显著差异( χ2 =3.86,P<0 .0 5) ;卖淫妇女 HBV感染率 ( 52 .73% )与对照组 ( 2 6.67% )有显著差异 ( χ2 =5.36,P<0 .0 5)。 5组人群未检出抗 - HDV阳性者。医务人员、卖淫妇女、有偿供血者、归国劳务人员、STD患者组的抗 - HEV感染率分别为 1.16%、3.64%、2 .2 7%、5.88%、6.82 % ,抗 - HCV感染率分别为1.16%、3.64%、0 .0 0 %、0 .0 0 %、1.14%。

Research on Risk Factors of 5 Types of Viral Hepatities Among Population with High Risk Behaviors

Epidemiological and serological survey on five types of viral hepatities (hepatitis A-hepatitis E) was conducted from October 1994 to December 1996 among 119 labourers returned from abroad, including 55 female prostitutes, 86 medical workers, 88 STD patients and 88 paid blood donors. HAV infection rates for all of the 5 groups were above 83%. HBV infection rate showed significantly different (chi 2 = 3.86, P < 0.05) between medical workers (53.49%) and the control group (30.43%). A significant difference (chi 2 = 5.36, P < 0.05) between HBV infection among prostitutes (52.73%) and control group (26.67%) was also noticed. In all the five groups, none was found to be anti-HDV positive. The HEV infection rates for the medical workers, prostitutes, blood donors, returned labourers and STD patients were 1.16%, 3.64%, 2.27%, 5.88% and 6.82%, whereas the anti-HCV positive rates were 1.16%, 3.64%, 0.00%, 0.00% and 1.14%, among them respectively.
