Viruses and Viral Infections

Respiratory Syncytial Virus

Respiratory syncytial virus (RSV) causes infections of the lungs and respiratory tract. Infection with respiratory syncytial virus which manifests primarily as bronchiolitis or viral pneumonia, is the leading cause of lower respiratory tract infections (LRTIs) in infants and young children.

Reye’s Syndrome

Reye's syndrome typically occurs after a viral illness, particularly an upper respiratory tract infection, influenza, varicella, or gastroenteritis, and is associated with the use of aspirin during the illness.
