There is no direct antiviral medication for adenovirus infection in infants; therefore, treatment focuses on alleviating symptoms. Easing symptoms improves the baby's comfort. Treatment options for adenovirus in infants may include:

* Using fever reducers if the baby has a high fever.
* Encouraging increased fluid intake to compensate for fluid loss caused by the infection.
* Using saline nasal drops or a nasal aspirator to relieve nasal congestion and improve breathing.
* Ensuring the baby gets plenty of rest and avoids overexertion.
* Practicing good hand hygiene to prevent the spread of infection. Hands should be washed before touching the baby.

In severe cases, adenovirus in infants can lead to serious complications such as pneumonia or bronchitis, manifested by symptoms like difficulty breathing, severe cough, or high fever. Medical attention should be sought if these symptoms develop.
