Human Respiratory Viruses 2008-07-30 .txt text/plain 5716 300 43 Respiratory syncytial virus (RSV) is the most common pathogen, with hMPV, PIV-3, influenza viruses, and rhinoviruses accounting for the majority of the remainder of acute viral respiratory infections. Respiratory syncytial virus (RSV), parainfluenza viruses (PIVs), adenoviruses, and influenza viruses were identified initially as the most common causes of serious lower respiratory tract disease in infants and children. These patients also suffer more frequent and more severe disease including mortality with common respiratory viruses, including RSV, hMPV, PIV, influenza viruses, rhinoviruses, and adenoviruses. Enterovirus infections occur most commonly in the summer months in temperate areas, which differs from the season of many of the other most common respiratory viruses such as paramyxoviruses and influenza virus. Humans generally do not develop lifelong immunity to reinfection with these viruses; rather, specific immunity protects against severe and lower respiratory tract disease.
