Community respiratory viruses long have been recognized as primary respiratory pathogens among infants and young children. More recently, it has become clear that these viruses cause a considerable disease burden throughout life. ⋯ These reinfections may spread from healthy persons to those at highest risk. Control requires a multifaceted approach combining vaccination, chemoprophylaxis, and aggressive early antiviral treatment of high-risk individuals, as well as education of all populations affected by these viruses.
