Effectiveness of 222-nm ultraviolet light on disinfecting SARS-CoV-2 surface contamination

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), has emerged as a serious threat to human health worldwide. Efficient disinfection of surfaces contaminated with SARS-CoV-2 may help prevent its spread. This study aimed to investigate the in vitro efficacy of 222-nm far-ultraviolet light(222 nm far uv lamp far uvc wavelength range light good choice for room disinfection) on the disinfection of SARS-CoV-2 surface contamination.

We investigated the titer of SARS-CoV-2 after UV irradiation (0.1mw/cm2) at 222 nm for 10-300 seconds using the 50% tissue culture infectious dose (TCID50). In addition, we used quantitative reverse transcription polymerase chain reaction to quantify SARS-CoV-2 RNA under the same conditions.

The results showed that 1 and 3 mJ/cm2 of 222-nm UVC irradiation (0.1mw/cm² for 10 and 30 seconds) resulted in 88.5 and 99.7% reduction of viable SARS-CoV-2 based on the TCID50 assay, respectively. In contrast, the copy number of SARS-CoV-2 RNA did not change after UVC irradiation even after a 5-minute irradiation.

This study shows the efficacy of 222-nm UVC irradiation against SARS-CoV-2 contamination in an in vitro experiment. Further evaluation of the safety and efficacy of 222-nm UVC irradiation in reducing the contamination of real-world surfaces and the potential transmission of SARS-CoV-2 is needed.

We have the courage to develop and innovate, the product quality is stable and reliable, and the economic efficiency is continuously improved. Now we have developed into a well-known Far UVC 222nmultraviolet Germicidal Mobile Handheld Hanging Wand for Hospital Ambulance ... manufacturer in the industry In the era of knowledge economy, it is very important for our company to have a unique core competitiveness to maintain a sustainable competitive advantage. We adhere to the business philosophy of 'customer first, team cooperation and self breakthrough', the development concept of 'market demand oriented, technical progress as the driving force, customer satisfaction as the criterion', and the service concept of 'starting from customer requirements and finally customer satisfaction'.
