小兒呼吸道病毒感染在嬰幼兒常造成嚴重威脅,效死率相當高也常造成住院醫療費用負擔的增加。本篇針對一些常見及新發現的呼吸道病毒做一簡單介紹,包括呼吸道融合病毒、流感病毒、鼻病毒、腺病毒、人類間質肺病毒、波卡病毒及冠狀病毒等等。雖然有許多病毒可在呼吸道檢體被偵測到,仍有許多呼吸道感染無法確認致病原,找尋出一些未知的病毒將會是一個重要的科學工作。
Respiratory tract viral infection in early childhood has a high mortality rate, and the hospitalization costs for treating the condition are often high. In this research, some common viruses and some newly identified respiratory viruses-including respiratory syncytial virus, influenza virus, rhinovirus, adenovirus, human metapneumovirus, bocavirus and coronavirus-are briefly reviewed. Numerous respiratory infections with unknown etiology may be caused by unidentified viruses, and the search for unknown viruses is an urgent scientific task.
