Disinfection methods against SARS-CoV-2: a systematic review

C. P. Viana Martins et al.

Summary: This study reviews the efficacy of various disinfection methods against SARS-CoV-2 based on up-to-date evidence. The results show that several household and hospital disinfection agents, as well as ultraviolet-C (UV-C) irradiation, are effective in inactivating SARS-CoV-2 on environmental surfaces. Formulations containing povidone-iodine have a virucidal effect on the skin and mucous membranes. Typical soap bars and alcohols can inactivate SARS-CoV-2 for hand hygiene. Air filtration systems with catalytic properties, UV-C devices, and heating systems can effectively reduce airborne viral particles. Decontamination of personal protective equipment (PPE) can be safely conducted through heat and ozone treatment.

Evaluation of Betacoronavirus OC43 and SARS-CoV-2 Elimination by Zefero Air Sanitizer Device in a Novel Laboratory Recirculation System

Marco Sebastiano Nicolo et al.

Summary: This study evaluated the virucidal efficacy of commercial air sanitizer Zefero against OC43 and SARS-CoV-2 viruses in different modes. The results showed that the integrated technologies in Zefero effectively eliminated both viruses. Additionally, a recirculation chamber was developed as a reliable experimental system for comparing the disinfection capacity of different air sanitizers.

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

Hiroki Kitagawa et al.

Summary: The study showed that 222-nm UVC irradiation was effective in reducing the viability of SARS-CoV-2 on surfaces, but had minimal impact on the virus RNA. Further research on the safety and effectiveness of 222-nm UVC in real-world settings is needed to assess its potential in preventing the spread of SARS-CoV-2.

Robust Evaluation of Ultraviolet-C Sensitivity for SARS-CoV-2 and Surrogate Coronaviruses

S. J. Boegel et al.

Summary: UV-C light at 254 nm is an effective means of disinfecting coronaviruses, including SARS-CoV-2. The study demonstrated that SARS-CoV-2, along with other coronaviruses, are easily inactivated by 254 nm irradiation, with similar UV sensitivities, making surrogate viruses useful for simplifying disinfection studies. Accurate measurement of light intensity, consideration of fluid UV absorbance, and confirmation of uniform dose delivery were essential in determining the UV sensitivity of these viruses.

Air Disinfection for Airborne Infection Control with a Focus on COVID-19: Why Germicidal UV is Essential†

Edward A. Nardell

Summary: Aerosol transmission is recognized as the main way COVID-19 spreads, highlighting the importance of ventilation. Mechanical ventilation in non-healthcare settings may not achieve recommended air changes per hour. Upper room germicidal UV air disinfection is a key technology for reducing COVID-19 transmission.

UV-C irradiation is highly effective in inactivating SARS-CoV-2 replication

Mara Biasin et al.

Summary: The study demonstrated that UV-C irradiation has strong virucidal effects on SARS-CoV-2, with a low dose being sufficient to inactivate the virus without replication. These findings provide an explanation for the epidemiological trends of COVID-19 and are crucial for developing novel sterilizing methods to contain SARS-CoV-2 infection.

Inactivation of Coronaviruses and Phage Phi6 from Irradiation across UVC Wavelengths

Ben Ma et al.

Summary: The study found that UVC devices can effectively inactivate enveloped viruses, with KrCl* excimer showing the best disinfection performance. Coronaviruses showed similar sensitivities to UV irradiation across different UVC wavelengths, while the bacteriophage surrogate was more resistant and exhibited higher sensitivity to Far UVC irradiation.

UV Inactivation of SARS-CoV-2 across the UVC Spectrum: KrCl* Excimer, Mercury-Vapor, and Light-Emitting-Diode (LED) Sources

Ben Ma et al.

Summary: The study evaluated the effectiveness of various UVC devices in inactivating SARS-CoV-2, with results showing that KrCl* excimer had the best disinfection performance. MHV can serve as a reliable surrogate of SARS-CoV-2 during UV disinfection tests, based on similar inactivation rate constants across wavelengths. UV light from KrCl* excimers can effectively reduce viral transmissions in public spaces.
