Adenovirus infections

Adenoviruses are a group of viruses that cause respiratory (breathing) illnesses, such as a common cold, conjunctivitis (an infection in the eye), croup, bronchitis, bronchiolitis (inflammation of the lower airways) and pneumonia. Most adenovirus infections are mild.

Adenoviruses can also cause urinary or intestinal tract infections. The Division of Infectious Diseases at Boston Children's Hospital provides consultative care for children and adolescents with all types of infections.

• Infections can occur at any age.
• Most children have had one form of the infection by age 10.
• They are contagious.
• The best way to prevent infections is by washing your hands.
• Treatment involves staying hydrated and may require medication.
