摘要: Understanding virus transfer between liquid and skin is necessary to estimate transmission during water-related activities. Here, we modeled from liquid-to-skin skin-to-liquid. We performed human subject studies using three bacteriophages as pathogenic surrogates: nonenveloped MS2 Qβ enveloped Φ6. Our study shows that describable by a single model based on (1) concentration (2) volume of remaining skin. Contact times (0.1–30 min), species had little-to-no influence transfer. Likewise, conditions (pH 6–9, ionic strength 10–550 mM) no shown for MS2. The accounts both, adsorbed onto the skin, in retained In comparison, skin-to-liquid was influenced wetness type (water, saliva). 90 ± 19% inoculated are transferred water when remains w...
