BACKGROUND
To review the effect of ultraviolet germicidal irradiation (UVGI) as a disinfection method for filtering facepiece respirators (FFRs) to facilitate reuse during COVID-19 pandemic.
METHODS
Systematic review of the research concerning UVGI for FFRs disinfection to facilitate reuse (also termed limited reuse) during respiratory infectious diseases where aerosol transmission is considered possible.
RESULTS
UVGI is one possible method for respiratory disinfection to facilitate the reuse of dwindling supplies. Appropriate dose UVGI exposition could provide enough energy to effectively decontaminate respiratory viral agents and maintain respirator's integrity for reuse. There was not currently sufficient research evidence on the effect of UVGI to inactivate coronaviruses SARS-CoV-2, and the practical application of UVGI is still unclear. .
CONCLUSION
Appropriate dose UVGI exposition could provide enough energy to effectively decontaminate respiratory viral agents and maintain respirator's integrity for reuse. Further evidence concerning UVGI as a decontamination technique specifically for SARS-CoV-2 isneeded.
背景
回顾紫外线杀菌（UVGI）作为过滤式面罩呼吸器（FFR）的消毒方法，以促进在 COVID-19 大流行期间的重复使用。
方法
系统综述了有关 UVGI 对 FFR 进行消毒以促进呼吸道传染病期间重复使用（也称为有限重复使用）的研究，在这些传染病中，气溶胶传播被认为是可能的。
结果
UVGI 是一种可能的呼吸消毒方法，可促进对日益减少的供应品的重复使用。适当剂量的 UVGI 暴露可以提供足够的能量，有效地清除呼吸道病毒，并保持呼吸器的完整性以供重复使用。目前尚无足够的研究证据表明 UVGI 可以灭活冠状病毒 SARS-CoV-2，UVGI 的实际应用仍不清楚。
结论
适当剂量的 UVGI 暴露可以提供足够的能量，有效地清除呼吸道病毒，并保持呼吸器的完整性以供重复使用。需要进一步研究 UVGI 作为 SARS-CoV-2 专门的消毒技术。
