儿童呼吸道合胞体病毒( RSV )。注意巨细胞，它是细胞病理效应的一部分。插图显示典型的巨细胞，圆形,有粉红色胞质包涵体。RSV是2岁以下儿童患肺炎的主要原因，同时也是1～6 个月或稍大的婴幼儿死亡的一个原因。
This is respiratory syntytial virus (RSV) in a child. Note the giant cells which are part of the viral cytopathic effect. The inset demonstrates a typical giant cell with a round, pink intracytoplasmic inclusion. RSV accounts for many cases of pneumonia in children under 2 years, and can be a cause for death in infants 1 to 6 months of age or older.
