Abstract

During or following human activity in the built environment, microbes on surfaces have the potential to be resuspended into the air and contaminate surrounding surfaces. The goal of this study was to explore the scope of viral dissemination (e.g., vertical and horizonal distance), resuspension and surface contamination after activities on indoor flooring surfaces (carpet and wood). Virus (MS2 bacteriophage) was inoculated onto nylon carpet or wood floors, with and without a dust matrix and indoor activities were conducted (walking/stomping and vacuuming). A statistically significant difference was found between virus resuspension associated with dust matrix compared to without dust (tripartite matrix) during vacuuming carpet (p value =.0000058) indicating greater exposure to virus laden dust particles. There was also a significant difference found between the distance of vertical or horizonal virus dispersal and dust matrix.
