A hybrid model integrating warm heat and ultraviolet germicidal irradiation might efficiently disinfect respirators and personal protective equipment

Rajib Banerjee et al.

Summary: This research proposes a hybrid model for sanitizing infected masks using user-friendly viral decontamination methods, showing better decontamination efficacy, operational speed, and reuse cycles compared to single methods. The model, originally intended for medical PPE, can also be applied to household and personal sanitation during the COVID-19 pandemic.

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.

Fast inactivation of SARS-CoV-2 by UV-C and ozone exposure on different materials

Elena Criscuolo et al.

Summary: The rapid spread of SARS-CoV-2 has led to over a million deaths from COVID-19. Proper disinfection of objects, tissues, and clothes can restrict viral transmission in public environments. Effective disinfection systems like UV-C and ozone can help prevent the spread of the virus.

Practical considerations for Ultraviolet-C radiation mediated decontamination of N95 respirator against SARS-CoV-2 virus

Guillaume R. Golovkine et al.

Summary: Decontaminating N95 respirators for reuse using Ultraviolet-C irradiation shows promising results, but the efficacy depends on the mask model, material, and location of contamination. Caution is needed when interpreting the effectiveness data from UV-C decontamination methods.

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.

Mechanistic theory predicts the effects of temperature and humidity on inactivation of SARS-CoV-2 and other enveloped viruses

Dylan H. Morris et al.

Summary: In this study, the stability of SARS-CoV-2 on inert surfaces under different temperature and humidity conditions was measured, and a mechanistic model was developed to explain and predict how temperature and humidity affect virus inactivation. The results showed that the virus survives longest at low temperatures and extreme humidity, with implications for understanding virus transmission mechanisms and strategies to mitigate transmission risk. The mechanistic model accurately predicted measurements of five different human coronaviruses, suggesting shared mechanisms may affect stability across various viruses.

Ultraviolet C lamps for disinfection of surfaces potentially contaminated with SARS-CoV-2 in critical hospital settings: examples of their use and some practical advice

Manuela Lualdi et al.

Summary: The spatial emission of UV-C lamps is strongly dependent on the power and design of reflectors, and correct calculation of exposure time is essential for disinfecting surfaces contaminated by SARS-CoV-2. In the absence of instruments for direct measurement of irradiance, it is advisable to increase the calculated irradiation time by at least 20%.

Inactivation of SARS-CoV-2 isolates from lineages B.1.1.7 (Alpha), P.1 (Gamma) and B.1.110 by heating and UV irradiation

S. Ulloa et al.

Summary: The article discusses methods of reducing the infectivity of SARS-CoV-2 through heating and irradiating UV-C light procedures. The study found no differences in the effectiveness of physicochemical treatment among different lineages, thus determining analytical conditions for efficient inactivation of SARS-CoV-2.

Effect of various decontamination procedures on disposable N95 mask integrity and SARS-CoV-2 infectivity

Jeffrey S. Smith et al.

Summary: The study tested the feasibility of VHP, UV, and ethanol decontamination on N95 masks, with ethanol and UV showing different degrees of degradation, while VHP treatment showed no significant change. Ethanol treatment was effective in eliminating detectable SARS-CoV-2 RNA in a virucidal experiment.
