Aim:  Gastro‐intestinal infections are widespread in the community and have considerable economic consequences. In this study, we followed chains of infection from a public toilet scenario, looking at infection risks by correlating the transmission of bacteria, fungi and viruses to our current knowledge of infectious doses. Methods and Results:  Transmission of Escherichia coli, Bacillus atrophaeus spores, Candida albicans and bacteriophage MS2 from hands to surfaces was examined in a transmission model, that is toilet brush, door handle to water tap. The load of viable pathogens was significantly reduced during transfer from hands to objects. Nevertheless, it was shown that pathogens were successfully transferred to other people in contagious doses by contact with contaminated surfaces. Conclusions:  Our results suggest that infection risks are mainly dependent on current infectious doses of pathogens. For enteritic viruses or bacteria, for example Norovirus or EHEC, only a few particles or cells are sufficient for infection in public lavatories, thus bearing a high risk of infection for other persons. However, there seems to be only a low probability of becoming infected with pathogens that have a high infectious dose whilst sharing the same bathroom. Significance and Impact of the Study:  The transmission model for micro‐organisms enables a risk assessment of gastro‐intestinal infections on the basis of a practical approach.

Viral infections like Herpes simplex increasingly pose a serious threat to European health care systems and welfare of the population. Indirect transmission routes of infections via inanimate surfaces are often underestimated. In this study, we investigated the adhesion and persistence of Herpes simplex virus on cotton fabrics as well as its inactivation by domestic laundry. Virus adhesion to textile fibers was distinct, because viral DNA was detectable on fabrics for at least 48 hours after contamination as well as after home laundry. Particles remained infectious for several hours at room temperature and partially for 48 hours at 2˚C -8˚C. Nevertheless, domestic laundry was able to inactivate virus particles given that detergents were adequately used. This confirmed that standard household laundry processes, as established in Europe, are a suitable tool to reduce infectious Herpes virus particles from textiles, thereby supporting the prevention of infections circulating in the household and community.

Phage-charged bioindicators may be a tool to provide further insights into the reliability of antiviral laundry processes for health care quality management and for infection control.

The utilization of adsorptive nonwovens as a pretreatment unit may lead to novel, cost-efficient wastewater treatment technologies with remarkable properties for environmental protection, such as efficient adsorption of antibiotics. This paper uses graphene-modified nonwoven (GMN) to examine (i) how the adsorption of tetracycline (TCY)—especially since this antibiotic is frequently detected in the environment—takes place on an environmentally relevant concentration scale, and (ii) what factors influence the antibacterial and antifungal properties profile of this material class. This study demonstrates that combining graphene particles with commercial textile auxiliaries clearly enhances the antibacterial and antifungal properties of the modified nonwoven materials. The enzyme-linked immunosorbent assay (ELISA) was used to detect the TCY residues at ng/mL scale. The adsorption results follow Henry and Redlich–Peterson isotherms and emphasize the adsorption process at low concentration levels of TCY. Therefore, the appropriately designed GMNs have a great potential application for wastewater treatment in sewage plants. Statistical analysis (skewness and kurtosis) of nonwovens and modified nonwovens morphology allowed us to determine the parameters influencing the growth of fungi in such structures. GMN structures are capable of adsorbing antibiotics; a two-fold reduction of TCY was obtained in the studies.
