Definition
Adenovirus is a common virus that can cause:
- The common cold, acute bronchitis, or pneumonia
- Infection of the eye called conjunctivitis
- Urinary tract infection
- Intestine infections
These infections can be more serious in those with weak immune systems. Examples are people with AIDS or organ transplants.
Causes
Adenoviruses pass from person to person. People get infected from:
- Inhaling the virus—when an infected person coughs or sneezes
- Shaking hands with an infected person
- Exposure to infected stool (poop), water, tissue, or blood
- Touching an object that contains the virus

- Long term care homes
- Schools or summer camps
- Public swimming pools
- A weak immune system
Symptoms
Adenoviruses can infect the:
- Nose, throat, and lungs
- Eyes
- Intestines
- Urinary tract
Symptoms depend on where the infection is. They may include:
-

Diagnosis
The doctor will ask about your symptoms and health history. A physical exam will be done.
A sample of body fluids may be taken and tested, such as:
- Mucous from throat or nose
- Stool
- Blood
- Urine
People with weak immune systems may need other tests.
Treatment
In general, adenovirus infections usually end on their own. People with weak immune systems may need supportive care and other treatments.
Options are:
- Rest, fluids, moist air, and pain medicines
- Eye ointments or drops—for conjunctivitis
- IV fluids—for severe vomiting or diarrhea
- Special medicines—for people with weak immune systems
