乙型肝炎患者的血液具有高度的传染性,0.00004ml即可引起感染。将乙型肝炎病毒(HBV)干燥血清稀释成10~(-7)～10~(-8)ml仍可使人或黑猩猩感染发病。HBV对理化因子抗力很强,在外环境中有较强的耐受力,室温(30～32℃)下可存活6个月,在60℃下经4h仍可使人感染。在医院内尤其是传染病医院内有HBV污染严重的区域,切实做好终末消毒及预防性消毒,切断传播途径,预防医源性感染,实为重要。为此,本文以几种常用的消毒剂和消毒方法对乙型肝炎患者血清(简称HBV血清)进行了感染指标(HBsAg、HBeAg、HBV-DNA)消除效果的比较观
Hepatitis B patients are highly contagious and 0.00004 ml can cause infection. Hepatitis B virus (HBV) dry serum diluted to 10 ~ (-7) ~ 10 ~ (-8) ml still make the human or chimpanzees infection. HBV is very resistant to physico-chemical factors and has strong tolerance in external environment. It can survive for 6 months at room temperature (30 to 32 ° C) and can still infect after 4 hours at 60 ° C. In hospitals, especially in infectious diseases hospitals have serious areas of HBV pollution, and effectively do the final disinfection and preventive disinfection, cut off the route of transmission, prevention of iatrogenic infection, it is very important. To this end, this article in several commonly used disinfectants and disinfection of hepatitis B patients serum (referred to as HBV serum) infection indicators (HBsAg, HBeAg, HBV-DNA) to eliminate the effect of comparison
