ABSTRACT

The spread of novel coronavirus disease 2019 (COVID-19) infections worldwide has raised concerns about the prevention and control of SARS-CoV-2. Devices that rapidly inactivate viruses can reduce the chance of infection through aerosols and contact transmission. This in vitro study demonstrated that irradiation with a deep ultraviolet light-emitting diode (DUV-LED) of 280 ± 5 nm wavelength rapidly inactivates SARS-CoV-2 obtained from a COVID-19 patient. Development of devices equipped with DUV-LED is expected to prevent virus invasion through the air and after touching contaminated objects.

用深紫外LED照射可快速灭活SARS-CoV-2。

摘要

全球新型冠状病毒疾病2019（COVID-19）感染的蔓延引起了人们对SARS-CoV-2预防和控制的担忧。快速灭活病毒的设备可以减少通过气溶胶和接触传播的感染机会。这项体外研究表明，用波长为280±5 nm的深紫外发光二极管（DUV-LED）照射可快速灭活从COVID-19患者那里获得的SARS-CoV-2。预计将开发配备DUV-LED的设备，以防止病毒通过空气以及接触被污染的物体而侵入。
