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 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.
新型冠状病毒病 2019（COVID-19）感染在全球范围内的传播引起了人们对 SARS-CoV-2 预防和控制的关注。能够快速使病毒失活的设备可以通过空气传播和接触传播来降低感染的机会。本研究表明，波长为 280±5nm 的深紫外发光二极管（DUV-LED）照射可以快速使从 COVID-19 患者中分离得到的 SARS-CoV-2 失活。预计配备 DUV-LED 的设备的开发将防止通过空气和接触污染物体后病毒的入侵。
