乙型肝炎传播途径比较复杂,其中最主要的是经血传播。因为乙型肝炎病毒主要存在于病人或携带者血液中。有人观察,只要注入含有乙型肝炎病毒的血液万分之一毫升,就可引起显性感染;千万分之一毫升的血液引起隐性感染。所以,在日常医疗过程中,如果手术器械、牙科器械、注射器、采血针、针灸针等消毒不严或达不到消毒要求,就会造成乙型肝炎医源性传播。
Hepatitis B transmission more complex, of which the most important is the spread of blood. Because hepatitis B virus is mainly present in the blood of patients or carriers. It has been observed that as long as one tenth of a milliliter of blood containing hepatitis B virus is injected, it can cause a dominant infection; millions of milliliters of blood cause a latent infection. Therefore, in the daily medical process, if the surgical instruments, dental equipment, syringes, lancets, acupuncture needles and other disinfection lax or less than the disinfection requirements, it will cause iatrogenic hepatitis B transmission.
