(RSV) Quick Facts:

  • Can affect persons of any age
  • Spread by inhaling droplets from an infected person’s sneeze or cough or through contact with contaminated surfaces
  • Symptoms may be mild to severe; a severe infection can pose a serious health threat
  • Most common cause of pneumonia in babies
  • Most common cause of inflammation of the small airways in the lungs
  • More common in winter and early spring
  • Often occurs in annual outbreaks in communities, classrooms and/or childcare centers
  • Most babies will have at least one occurrence by the age of 2

Symptoms

  • Begin two to five days after contact with the virus. Early phase RSV symptoms are often mild and cold-like. In children younger than 3, RSV may move into lungs. Coughing, sneezing and wheezing may occur. Difficulty breathing may become severe, requiring hospitalization. Symptoms may include:

  • Runny nose
  • Fever
  • Cough
  • Apnea (brief interruptions in breathing)

Most at risk

  • Babies born prematurely
  • Babies with any heart, lung or immune system conditions are at risk for more severe impact from the virus
