Parainfluenza viruses types 1, 2 and 3 were found in 2·5%, 0·8% and 1·6% respectively of patients examined in the MRC/PHLS general practice survey and in 2·2%, 0·7% and 2·7% of those in the hospital survey. Type 3 infections were found earlier in life than type 1, while type 2 infections tended to be detected in older children. These viruses were found most frequently in croup and laryngitis but were also common causes of coryza and lower respiratory infections, especially in general practice. The epidemiology and diagnosis of parainfluenza virus infections are discussed briefly.
在医学研究委员会/公共卫生实验室服务处的全科医疗调查中，分别有2.5%、0.8%和1.6%的受检患者被检测出感染1型、2型和3型副流感病毒；在医院调查中，相应比例分别为2.2%、0.7%和2.7%。3型感染在生命早期比1型感染更早出现，而2型感染往往在年龄较大的儿童中被检测到。这些病毒在哮吼和喉炎中最常见，但也是普通感冒和下呼吸道感染的常见病因，尤其是在全科医疗中。本文简要讨论了副流感病毒感染的流行病学和诊断方法。
