​​Adenoviruses are a group of viruses that infect the tissue linings, which include membranes in the eyes, respiratory tract, intestines, urinary tract and nervous system. Infants or individuals with weak immune systems are more prone to get adenoviruses.


Symptoms of adenoviruses are typically mild. They can vary greatly and cause a range of illnesses.

Some symptoms include:

  • Common Cold
  • Sore Throat
  • Pink Eye (viral)
  • Fever
  • Pneumonia
  • Bronchitis
  • Vomiting and/or Diarrhea


Adenoviruses are highly contagious. They tend to be resistant to many disinfectant products and can remain on surfaces and objects for long periods of time.

While there is no vaccine for adenovirus, there are steps that can be taken to help prevent and protect against adenovirus.

Boys Town Pediatrics recommends the following steps:

  • Wash your hands with soap and water often.​
  • Avoid touching your mouth, nose or eyes.
  • Avoid close contact with people who are sick.


Typically infections get better on their own and are a few days to a week or two in duration. Getting plenty of rest, drinking enough liquids and taking acetaminophen to treat fevers should help in recovering from an adenovirus.
