Infection with adenoviruses typically occurs as result of close contact with someone already infected, or by touching surfaces or objects that have adenoviruses on them and then touching the mouth, nose or eyes. Outbreaks of conjunctivitis caused by certain serotypes of adenoviruses have also been traced to inadequately chlorinated swimming pools or contaminated ophthalmic medications.

A vaccine against adenovirus types 4 and 7 was approved by the U.S. Food and Drug Administration in March 2011 for U.S. military personnel only. The vaccine is not available to the public. Prevention of adenovirus infection requires careful attention to hygienic measures including:

• Washing hands often with soap and water

• Covering the mouth and nose when coughing or sneezing

• Not touching the eyes, nose or mouth

• Avoiding close contact with people who are sick 

• Staying home when ill

Adenovirus infections were traditionally diagnosed by cell culture since adenoviruses readily replicate in cell culture. Monoclonal antibodies are also used to detect infected cells using direct fluorescence antibody assays. Polymerase chain reaction methods that amplify and detect adenovirus DNA are also now becoming a commonly used laboratory method to confirm adenovirus infection.

Most adenovirus infections are mild and typically do not require much medical treatment outside of managing the symptoms. More serious adenovirus infections are managed by treating symptoms and complications of the infection. In some cases, cidofovir (a nucleotide analog) may be used to treat severe adenovirus infections in people with immunocompromised systems.
