乙型肝炎病毒通过泪液传播的研究进展

Research advances of hepatitis B virus transmission through tears

我国乙肝病毒携带者较多,人群中乙肝患者通过血液传播的比例较大,但目前仍有部分传播方式不明确。怀疑与日常生活密切接触的各种体液有关。在眼科日常检查中,仍有部分检查无法采用非接触的方法,这就为病毒等通过眼科接触性检查上的残留泪液进行传播带来风险。因此在眼科中,对于乙肝患者泪液传染性的研究是十分有必要的。本文将针对乙型肝炎病毒通过泪液传播的研究进展进行综述。

China has a large number of Hepatitis B virus carriers. Though hematogenous dissemination is the main transmission route, much remains unknown about the way the virus spreads. It is doubted that people may get the disease through various body fluids in daily activity. Some routine examinations in ophthalmology department such as Goldmann applanation tonometry could not avoid contact with patients＇ ocular surface and may cause virus spread due to the residual tears on the instrument. So it is quite necessary to inspect the tear infectiousness of Hepatitis B virus. This review summarized recent studies about hepatitis B virus transmission via tears.
