“…can deactivate the enveloped viruses via the oxidation of thiol groups in virus proteins and denaturation of proteins. [ 42 , 43 , 44 , 45 ] Similarly, iodophors can release iodine which can penetrate into the membrane and oxidize the proteins’ thiols and also damage the RNA of the virus. Therefore, tethering of the safe oxidizing agents on the surface of personal protection equipment (PPE) can be used as an appropriate approach for fabrication of antiviral PPEs.…”

The outbreak of COVID‐19 revealed the vulnerability of commercially available face masks. Without having antibacterial/antiviral activities, the current masks act only as filtering materials of the aerosols containing microorganisms. Meanwhile, in surgical masks, the viral and bacterial filtration highly depends on the electrostatic charges of masks. These electrostatic charges disappear after 8 h, which leads to a significant decline in filtration efficiency. Therefore, to enhance the masks’ protection performance, fabrication of innovative masks with more advanced functions is in urgent demand. This review summarizes the various functionalizing agents which can endow four important functions in the masks including i) boosting the antimicrobial and self‐disinfectant characteristics via incorporating metal nanoparticles or photosensitizers, ii) increasing the self‐cleaning by inserting superhydrophobic materials such as graphenes and alkyl silanes, iii) creating photo/electrothermal properties by forming graphene and metal thin films within the masks, and iv) incorporating triboelectric nanogenerators among the friction layers of masks to stabilize the electrostatic charges and facilitating the recharging of masks. The strategies for creating these properties toward the functionalized masks are discussed in detail. The effectiveness and limitation of each method in generating the desired properties are well‐explained along with addressing the prospects for the future development of masks.

“…Peracetic acid (CH 3 COOOH), Figure 13 , is an organic peroxide with activity against mycobacteria, viruses, spores, molds at low concentrations. It results to be a more potent antimicrobial agent than hydrogen peroxide [ 104 , 105 ]. Peracetic acid is a strong oxidizing agent that provides innocuous decompositions by-products: acetic acid and hydrogen peroxide.…”

From viruses to bacteria, our lives are filled with exposure to germs. In built environments, exposure to infectious microorganisms and their byproducts is clearly linked to human health. In the last year, public health emergency surrounding the COVID-19 pandemic stressed the importance of having good biosafety measures and practices. To prevent infection from spreading and to maintain the barrier, disinfection and hygiene habits are crucial, especially when the microorganism can persist and survive on surfaces. Contaminated surfaces are called fomites and on them, microorganisms can survive even for months. As a consequence, fomites serve as a second reservoir and transfer pathogens between hosts. The knowledge of microorganisms, type of surface, and antimicrobial agent is fundamental to develop the best approach to sanitize fomites and to obtain good disinfection levels. Hence, this review has the purpose to briefly describe the organisms, the kind of risk associated with them, and the main classes of antimicrobials for surfaces, to help choose the right approach to prevent exposure to pathogens.

“…In health institutions, fumigation with hydrogen peroxide, peracetic acid, and ultraviolet light lamps have been used for terminal disinfection of patient rooms, which does not replace the need for manual cleaning and disinfection of surfaces [30,31]. If we consider the environmental survival of coronaviruses, the effectiveness of surface disinfection (performed by rubbing or scrubbing with selected solutions), and the cost of fumigation or ultraviolet radiation technologies, most probably the cost outweighs the benefits in terms of prevention.…”

Background: The rationale of transmission prevention is related to transmission mechanisms, and evidence from observations has shown an improper use of personal protective equipment (PPE). Objective: We aim to describe the evidence on the transmission mechanisms of severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) and related prevention practices. Method: Review of the published literature on coronavirus disease 2019 (COVID-19) in the Scopus, Science Direct, and PubMed databases. Results: Transmission of respiratory viruses, including SARS CoV-2, could be by aerosols, droplets and contact with contaminated surfaces. Evidence suggests that the primary route of transmission of these viruses is by droplet and short distance. Scientific evidence in relation to the transmission of COVID-19 assigns the highest risk to the aerosol-generating procedures and by droplets in closed environments with poor ventilation, and the lowest risk of transmission by direct contact with contaminated surfaces. Conclusion: Prevention practices must be in correspondence with the evidence about the transmission of COVID-19, which will facilitate the rational use of available resources.
