Symptoms

Adenoviruses can cause a wide range of illnesses such as

  • Common cold
  • Sore throat
  • Bronchitis (a condition that occurs when the airways in the lungs become filled with mucus and may spasm, which causes a person to cough and have shortness of breath)
  • Pneumonia (infection of the lungs)
  • Diarrhea
  • Pink eye (conjunctivitis)
  • Fever
  • Bladder inflammation or infection
  • Inflammation of stomach and intestines
  • 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.
