“…Manual cleaning is not standardized and often refuses to remove bioburden on frequently touched surfaces, because of different personal-related reasons ( 17 , 18 , 22 ). Therefore, automated room decontamination systems could be a suitable method to enhance the success of cleaning and disinfection processes in hospitals.…”

“…Therefore, automated room decontamination systems could be a suitable method to enhance the success of cleaning and disinfection processes in hospitals. The efficacy of a procedure, the ease and safety of use, rapid availability and ability to be integrated into routine processes are important for using new standardized procedures for final disinfection ( 18 ). Therefore, studies characterizing such devices are essential to ensure effectivity as well as safe operation in hospitals.…”

“…In contrast, there is no possibility of monitoring or logging process parameters for the simple aHP nebulizer. For such devices, it is recommended to use additional measurement equipment to verify sufficient concentration and ensure adherence to safety exposure limits afterwards ( 18 ). Both principles of action are based on reactive oxygen species that inactivate pathogens, so that sensitive materials could be attacked.…”

To evaluate the effectiveness of automated room decontamination devices, a common aerosolized hydrogen peroxide (aHP) as well as a recent gaseous ozone-based device, which produces the disinfectant reagent without the need of consumables, were tested under real-life conditions. Twenty-two contaminated surfaces were positioned in different areas in a patient room with adjacent bathroom and anteroom. Following the decontamination process bacteria were recovered and reduction factors were calculated after performing quantitative culture. Following the manufactures instructions, the ozone-based device displayed a bactericidal effect (log10 > 5), whereas the aHP system failed for a high bacterial burden and achieves only a complete elimination of a realistic bioburden (log10 2). After increasing the exposure time to 30 min, the aHP device also reached a bactericidal effect. Nevertheless, our results indicate, that further research and development is necessary, to get knowledge about toxicity, efficacy and safety by using in complex hospital conditions and achieve meaningful integration in cleaning procedures, to reach positive effects on disinfection performance.

“…However, ozone causes some materials (e.g., natural rubber) to corrode. Also, for it to be effective, considerable humidity of the environment is necessary [42]. According to research by Sato et al [43], for the virus to be inactivated, ≥80% air humidity is required.…”

The outbreak of coronavirus disease 2019 (COVID-19) generated a huge pressure on health care systems worldwide and exposed their lack of preparation for a major health crisis. In the times of a respiratory disease pandemic, members of the dental profession, due to having a direct contact with the patients' oral cavity, body fluids and airborne pathogens, are exposed to a great occupational hazard of becoming infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The authors carried out a systematic literature search using the main online databases

Disinfection of hospital facilities and ambulances is an important issue for breaking the chain of transmission of viral pathogens. Hydrogen peroxide has provided promising results in laboratory assays. Here, we evaluate the efficacy of a hydrogen peroxide nebulizer for the inactivation of surrogate MS2 bacteriophage and murine norovirus (MNV) in a patient waiting room and the fully equipped cabin of a medical ambulance. We observed an average 3 log 10 titer reduction in both settings, which represents the destruction of over 10 6 and 10 9 infectious particles of MNV and MS2 per cm 2 , respectively. The potential for viral exposure is high for health workers when disinfecting confined and cluttered spaces, so the use of a hydrogen peroxide mist might offer an affordable and efficient solution to minimize the risk of viral contaminations.
