Quantitative Studies on Fabrics as Disseminators of Viruses

摘要: The effects of laundering with both anionic and nonionic detergents in cold, warm, hot water on poliovirus-contaminated cotton sheeting, terry cloth, washable wool shirting, blanketing, dull nylon jersey, dacron/cotton shirting were determined. fabrics exposed to virus by aerosolization direct contact (pipette) separate studies. Although the results varied each factor used study, titers all generally reduced considerably process. When dried for 20 hr after laundering, an additional decline was seen, often below detectable levels. type detergent made little difference effect titer reduction, but wash markedly virus. Fabric not a major majority experiments, although tended be eliminated more readily from warm persisted longer blanketing material laundered detergent. Sterile similar which contained became contaminated during Virus ranging undetectable 103.9 cell culture 50% infectious doses/ml obtained samples rinse warm- cold-water laundering.
