Adenoviruses can cause a wide range of illnesses such as

  • common cold or flu-like symptoms
  • fever
  • sore throat
  • acute bronchitis (inflammation of the airways of the lungs, sometimes called a “chest cold”)
  • pneumonia (infection of the lungs)
  • pink eye (conjunctivitis)
  • acute gastroenteritis (inflammation of the stomach or intestines causing diarrhea, vomiting, nausea and stomach pain)

Less common symptoms of adenovirus infection include

  • bladder inflammation or infection
  • neurologic disease (conditions that affect the brain and spinal cord)

Adenoviruses can cause mild to severe illness, though serious illness is less common. People with weakened immune systems, or existing respiratory or cardiac disease, are at higher risk of developing severe illness from an adenovirus infection.
