Management of Symptoms

The following steps may help you be more comfortable:

  • Get plenty of rest.
  • Drink plenty of fluids.
  • Use a humidifier or vaporizer.
  • Take over-the-counter pain medications if you have discomfort.

If you have conjunctivitis, your doctor may have you use warm compresses. You may also be given eye ointments or drops.

Fluid Replacement

Severe diarrhea or vomiting can lead to dehydration. Fluids may need to be given by IV.

Medical Treatment

Infections can be more severe in people with a weak immune system. This may include people with organ transplants, HIV/AIDS, or chronic diseases. Medication may be needed to reduce the intensity of the infection. Talk to your doctor if you have a weakened immune system..

Prevention

The best way to prevent adenovirus infection is to:

  • Avoid contact with infected persons.
  • Wash hands often.
  • Wash and clean common surfaces, such as counters and toys.
  • Avoid touching your nose, mouth, and eyes.

Military personnel aged 17 to 50 years of age may be eligible to get the adenovirus vaccine. It is available in a pill form.
