Causes

Adenoviruses are a group of viruses that are a frequent cause of acute respiratory tract infections (ie, common colds ), as well as a number of other types of infections. Adenoviruses can be spread through:

  • Being exposed to a sneeze or cough of an infected person
  • Fecal contamination (eg, water supplies, poor hygiene)
  • Eating food contaminated by houseflies
  • Person-to-person contact
  • Handling an object that was exposed to an infected person
  • Swimming in lakes or pools

Risk Factors

A risk factor is something that increases your chance of getting a disease or condition.

The following factor is thought to increase the risk of developing an adenovirus infection:

  • Age: childhood, especially young children

Symptoms

Depending on where the infection occurs, symptoms of adenovirus infection may include:

Diagnosis

Your doctor will ask about your symptoms and medical history, and perform a physical exam. Depending on the type of infection that is suspected, he or she may also take mucous, stool, blood, and/or urine samples for testing in the laboratory.

Treatment

Talk with your doctor about the best treatment plan for you. Treatment will depend on the type of infection you have. Treatment options include:

Management of Symptoms

Since adenovirus infections will usually subside with time, treatment often focuses on making the patient more comfortable. This may include plenty of rest, extra fluids, a humidifier, acetaminophen, and/or over-the-counter medications. In cases of conjunctivitis, warm compresses and eye ointments or drops may be recommended.

Fluid Replacement

If you have severe diarrhea or vomiting, fluids may need to be given via an intravenous line to prevent dehydration.

Medical Treatment

Rarely, a doctor may administer certain medicines for life-threatening adenovirus infections in those patients that are severely immunocompromised.

Prevention

The best way to prevent adenovirus infection is to avoid contact with infected persons and practice good hygiene, including frequent hand washing and cleaning of shared surfaces (eg, countertops, toys). In addition, keeping swimming pools adequately chlorinated may prevent outbreaks of adenovirus infection associated with swimming pools.
