Three dilutions of each of three parainfluenza strains were placed on nonabsorptive (stainless steel, laminated plastic, skin) and absorptive (hospital 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. Additionally, 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.
将三种副流感病毒株各进行三种稀释度处理，分别置于非吸收性（不锈钢、层压塑料、皮肤）和吸收性（医院 gown、面巾纸、实验室工作服）表面，以评估在 0、0.5、1、2、4、6、8 和 10 小时时病毒回收的持续性。病毒在不锈钢表面持续时间最长。此外，通过增加初始接种物中病毒的初始浓度，提高了回收病毒的能力。接种物在表面干燥会降低但不会立即消除回收病毒的能力。用多种常用的消毒剂或防腐剂清洁受污染表面，只需短时间接触就能减少或消除病毒。通过大力清洁去除污染物质可能与实际的消毒物质同样重要。一般来说，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可持续长达 10 小时，在吸收性表面上可持续长达 4 小时，这表明需要考虑污染物可能是医院内外副流感病毒传播的一个来源。 （注：原文中“hospital gown”不太明确具体是什么，这里暂译为“医院 gown”）
