“…Virus stocks were prepared as described before (10). The poliovirus stock contained 1.6 ϫ 10 7 50% tissue culture infective doses (TCID 50 /ml), and the influenza A (H1N1) virus stock contained 4.0 ϫ 10 6 TCID 50 /ml.…”

“…The poliovirus was left on the coated surfaces for 1 and 6 h and influenza virus for 2 min and 1 h, respectively. The viruses were removed from the glass slides by swabbing with rayon swab sticks (Copan) as described before and from the plastic wells by rinsing with 1 ml cell culture medium (10). Visual inspection of the coatings after virus removal did not show any damage to the coat.…”

“…Visual inspection of the coatings after virus removal did not show any damage to the coat. Enumeration of the viruses and quantitative real-time reverse transcription (RT)-PCR was performed as described previously (10). Data for environmental resistance are presented as total infective viruses recovered from the surfaces (at t ϭ 0 h, the suspension is not yet dried), and data for virucidal activity of the IQACs are presented as reduction relative to uncoated glass and plastic carriers.…”

“…Viruses were enumerated by endpoint titration in 96-well plates (42,45). Cells were seeded in a concentration of 2 ϫ 10 5 cells/ml, and 10-fold serial dilutions in fetal calf serum (FCS)-free medium were prepared (eight dilutions, 10 replicates with each), followed by inoculation in a 96-well plate.…”

“…hAdV-5 and MNV-1 were detected as described by Verhaelen et al (45), and hNoV GI, hNoV GII, and influenza virus were detected as described by Tuladhar et al (47) and Svraka et al (48). Inhibition controls were included in all PCRs to monitor PCR inhibition (42,45,48). The fragment length analyzed was short and varied from 95 to 149 nucleotides.…”

bTransmission of enteric and respiratory viruses, including human norovirus (hNoV) and human influenza virus, may involve surfaces. In food preparation and health care settings, surfaces are cleaned with wipes; however, wiping may not efficiently reduce contamination or may even spread viruses, increasing a potential public health risk. The virucidal properties of wipes with a singlet-oxygen-generating immobilized photosensitizer (IPS) coating were compared to those of similar but uncoated wipes (non-IPS) and of commonly used viscose wipes. Wipes were spiked with hNoV GI.4 and GII.4, murine norovirus 1 (MNV-1), human adenovirus type 5 (hAdV-5), and influenza virus H1N1 to study viral persistence. We also determined residual and transferred virus proportions on steel carriers after successively wiping a contaminated and an uncontaminated steel carrier. On IPS wipes only, influenza viruses were promptly inactivated with a 5-log 10 reduction. D values of infectious MNV-1 and hAdV-5 were 8.7 and 7.0 h on IPS wipes, 11.6 and 9.3 h on non-IPS wipes, and 10.2 and 8.2 h on viscose wipes, respectively. Independently of the type of wipe, dry cleaning removed, or drastically reduced, initial spot contamination of hNoV on surfaces. All wipes transferred hNoV to an uncontaminated carrier; however, the risk of continued transmission by reuse of wipes after 6 and 24 h was limited for all viruses. We conclude that cleaning wet spots with dry wipes efficiently reduced spot contamination on surfaces but that cross-contamination with noroviruses by wiping may result in an increased public health risk at high initial virus loads. For influenza virus, IPS wipes present an efficient one-step procedure for cleaning and disinfecting contaminated surfaces.
