49018 Background 背景
49019 This document provides interim guidance on the management of the blood supply in response to the pandemic outbreak of coronavirus disease (COVID-19). 本文件提供了针对冠状病毒病（COVID-19)大流行的血液供应管理临时指南。
49020 It is intended for blood services, national health authorities, and others responsible for the provision of blood and blood components and integration of the blood system within the public health system. 指南面向血液中心、国家卫生主管部门和其它负责提供血液和血液成分以及将血液系统纳入公共卫生系统的机构。
49021 WHO will continue to update this guidance as new information becomes available. 随着新信息的出现，世卫组织将继续更新这份指导文件。
49022 This document is adapted from the WHO Guidance for National Blood Services on Protecting the Blood Supply During Infectious Disease Outbreaks and risk assessment publications on COVID-19 from regional networks/institutions. 本文件改编自世卫组织《国家血液中心在传染病暴发期间保障血液供应指南》和区域网络/机构关于COVID-19的风险评估出版物。
49023 General considerations —般考虑事项
49024 The COVID-19 virus outbreak is primarily transmitted by the respiratory route and theoretically by transfusions. COVID-19疫情的病毒主要通过呼吸道传播，理论上可以通过输血传播。
49025 The epidemic has the potential to reduce the supply of blood and blood components and adversely affect blood system activities. 该流行病有可能减少血液和血液成分的供应，对血液系统的活动产生不利影响。
49026 Blood services should therefore take steps to assess, plan, and respond appropriately and proportionately. 因此，血液中心应采取措施，进行评估、规划，并作出适当和相称的回应。
49027 The risk of transmission of COVID-19 through transfusion of blood and components is now only theoretical and likely minimal. 通过输注血液和血液成分传播COVID-19的风险现在只是理论上的，可能风险极低。
