Special Issue Information

Dear Colleagues,

Viruses, especially foodborne, airborne, and waterborne viruses, are inherently highly contagious and pose significant public health challenges. The emergence of the SARS-CoV-2 pandemic in 2019, the ongoing challenge of human norovirus as a leading foodborne pathogen, and recurrent outbreaks of the H1N1 influenza virus have highlighted the critical importance of environmental virus detection and disinfection, particularly considering the limited effectiveness of vaccines against certain viral strains.

Unlike bacteria, which can be enriched in appropriate media, detecting viruses in environmental samples is notably challenging. This difficulty stems from their low concentrations and the necessity for concentration techniques and special recovery to ensure accurate detection. Moreover, many commonly used sanitizers or disinfectants exhibit limited efficacy against non-enveloped viruses such as human norovirus and hepatitis A virus. For instance, studies have shown that both viruses demonstrate resistance to several classes of commercial disinfectants, necessitating higher concentrations and longer contact times for effective inactivation.

The complexity of environmental conditions—including factors such as surface materials and conditions, humidity, and temperature—adds further challenges to effective viral control. These variables can affect both the persistence of viruses on surfaces and the efficacy of antimicrobial agents. Therefore, there is a critical and urgent need to deepen our understanding of viral persistence and decontamination, and to explore innovative technologies for viral inactivation. Advancing research in this area is essential to mitigate the spread of highly contagious viruses in diverse settings, including long-term care facilities, medical centers, and food service environments, and to strengthening public health protection.

We look forward to receiving your contributions.

Fomites are common vehicles for viral transmission. Most studies on virus disinfection have focused on non-porous, hard surfaces, with few investigating porous materials. This review addresses two research questions: (1) What affects viral viability on reusable porous materials? (2) Which antimicrobials effectively target viruses on these materials? Among existing studies, viral persistence on reusable porous surfaces was influenced by several factors, including viral envelope status, virus subtype, material type and structure, temperature, relative humidity, deposition method, and transmission medium. Disinfectants evaluated included ultraviolet irradiation, steam, chlorine, quaternary ammonium compounds, alcohols, glutaraldehyde, silver, and peroxide-based agents. Chlorine and steam were most effective; glutaraldehyde and peroxides showed limited action against non-enveloped viruses. Viral persistence and disinfection efficacy on reusable porous materials are influenced by multiple factors, highlighting the need for robust environmental management and infection control practices. Lack of standard tests and long-term disinfection effects on material integrity remain key challenges needing further study. Full article
