在非吸收性（不锈钢、层压塑料、皮肤）和吸收性（医院长袍、面巾纸、实验室外套）表面分别稀释三种副流感病毒株，评估病毒在0、0.5、1、2、4、6、8和10小时的持续恢复情况。病毒在不锈钢上存留时间最长。此外，通过增加初始接种物中病毒的初始浓度，可以增强病毒的恢复能力。接种物表面的干燥会降低但不会立即消除恢复病毒的能力。用一些常用的消毒剂或防腐剂清洁被污染的表面，只需要很短的接触时间就可以减少或消除病毒。通过强力清洁去除污染物质可能与实际的消毒物质同样重要。总的来说，所有三种副流感病毒株的反应相似。所有三种副流感病毒株在非吸收性表面上持续时间长达10小时，在吸收性表面上持续时间长达4小时，这表明需要考虑污染物是副流感病毒在医院内外传播的可能来源。
Three dilutions of each of three parainfluenza strains were placed on nonabsorptive (stainless steel, laminated plastic, skin) and absorptive (hosptial gown, facial tissue, laboratory coat) surfaces to assess persistence of virus recovery at 0, 0.5, 1, 2, 4, 6, 8, and 10 hours. Virus persisted longest on stainless steel. Additonally, the ability to recover virus was enhanced by increasing the initial concentration of virus in the initial inoculum. Drying of the inoculum on surfaces reduced but did not immediately eliminate the ability to recover virus. Cleaning the contaminated surface with a number of commonly available disinfectant or antiseptic agents reduced or eliminated virus with only short exposure times. It is likely that removal of contaminated material by vigorous cleaning was as important as the actual disinfecting substance. In general, all three strains of parainfluenza virus responded similarly. Persistence of all three strains of parainfluenza virus for up to 10 hours on nonabsorptive surfaces and up to 4 hours on absorptive surfaces suggests a need to consider fomites a possible source of transmission of the parainfluenza viruses inside and outside the hospital.
