zh-cn	有两项研究称使用LPV/r作为接触后预防SARS-CoV和MERS-CoV的方法。
en-us	Two studies have reported the use of LPV/r as post-exposure prophylaxis for SARS-CoV and MERS-CoV. 

zh-cn	其中一项研究表明，与未服用任何药物的卫生工作者相比，服用LPV/r的卫生工作者中MERS-CoV感染的发生率较低；
en-us	One of these studies suggested that the occurrence of MERS-CoV infection was lower among health workers receiving LPV/r compared to those who did not receive any drugs; 

zh-cn	另一项研究指出，在与SARS患者住在同一病房的19名艾滋病毒感染者中，没有发现SARS-CoV感染病例，其中11人正在接受抗逆转录病毒治疗。
en-us	the other study found no cases of SARS-CoV infection among 19 people living with HIV hospitalized in the same ward of SARS patients, of whom 11 were on antiretroviral therapy. 

zh-cn	同样，由于样本量小、所提供药物的可变性以及暴露强度的不确定性，证据的确定性非常低。
en-us	Again, the certainty of the evidence is very low due to small sample size, variability in drugs provided, and uncertainty regarding intensity of exposure.
