Abstract

We have reviewed the primary literature on the virucidal efficacy of microbicidal active ingredients, formulated microbicides, and physical inactivation approaches (heat, irradiation) for hemorrhagic fever viruses (HFVs) (arenaviruses, filoviruses, flaviviruses, hantaviruses, nairoviruses, and phenuiviruses), and for two non-typical HFV paramyxoviruses. As each of these HFVs are large, lipid-enveloped RNA viruses, their susceptibilities to virucidal agents are informed by the so-called hierarchy of susceptibility of pathogens to microbicides. The unique susceptibility of lipid-enveloped viruses to most classes of microbicides is based on the common mechanisms of action of envelope-disrupting microbicides. Despite this, due to the relatively great lethality of these viruses, it is prudent (where possible) to confirm the expected efficacies of inactivation approaches in testing involving the HFVs themselves (as opposed to less lethal surrogate viruses) using field-relevant methods. Empirical data for virucidal activities of microbicidal active ingredients, formulated microbicides, and physical inactivation approaches, such as heat, ultraviolet light, and gamma irradiation, that were collected specifically for HFVs have been reviewed and summarized in this paper. These empirical data for surface and hand hygiene approaches, liquid inactivation approaches, and approaches for rendering diagnostic samples safe to handle inform non-pharmaceutical interventions intended to mitigate transmission risk associated with these HFVs.

摘要

我们回顾了关于杀微生物活性成分、配方杀微生物剂以及物理灭活方法(加热、辐照)对出血热病毒(HFV,包括沙粒病毒、丝状病毒、黄病毒、汉坦病毒、内罗病毒和白蛉病毒)以及两种非典型HFV副粘病毒的杀病毒效力的主要文献。由于这些HFV均为大型、有包膜的RNA病毒,它们对杀病毒剂的敏感性遵循所谓的病原体对杀微生物剂的敏感性等级。有包膜病毒对大多数种类杀微生物剂的独特敏感性基于破坏包膜的杀微生物剂的共同作用机制。尽管如此,鉴于这些病毒的致死率相对较高,在使用与实际情况相关的方法进行涉及HFV本身(而非致死性较低的替代病毒)的测试时,谨慎做法是(在可能的情况下)确认灭活方法的预期效力。本文回顾并总结了专门针对HFV收集的杀微生物活性成分、配方杀微生物剂以及物理灭活方法(如加热、紫外线和伽马辐照)的杀病毒活性的实验数据。这些关于表面和手部卫生方法、液体灭活方法以及使诊断样本安全处理的方法的实验数据为旨在降低与这些HFV相关的传播风险的非药物干预措施提供了参考。
