Adenovirus - Information for Patients


What kind of infection is it?

Adenovirus is a virus. Some types of adenovirus cause diarrhea, other types cause pinkeye, cough, sore throat and other illnesses.

How do people get infected?

  1. Adenovirus diarrhea is quite common in young children under 5 years of age.
  2. Adenovirus is spread person to person by contact with stool (poop) from an infected person.
  3. Poor hand washing after using the bathroom or changing diapers can contaminate food or surfaces.
  4. Outbreaks have been reported in day care centers.

What are the usual symptoms?

  1. Illness usually starts 8-10 days after exposure.
  2. Watery diarrhea, stomach pain or cramps, and fever.

How long does it last?

  1. Typically 4-8 days. The illness can be prolonged, especially in children with weakened immune systems or poor health.

How is it treated?

  1. Prevent dehydration by drinking fluids. Sometimes anti-nausea medicines or IV fluids may be necessary if you or your child cannot keep down any fluids. Warning signs of dehydration include a dry mouth, decreased urination, or dizziness.
  2. Because this is a viral infeciton, antibiotics do not help and may make the diarrhea worse.

Are there possible complications?

  1. Dehydration is the major complication.
  2. Diarrhea can be prolonged, especially for children with a weakened immune system.
  3. Bloody diarrhea can occur but this is rare.
  4. Prolonged abdominal pain due to swelling of lymph nodes in the abdomen (mesenteric adenitis) can occur.
  5. Severe complications can occur in transplant patients and others with severely weakened immune systems.

Comments:

  1. Wash hands carefully with soap and water after going to the bathroom or changing diapers, or cleaning up vomit or stool.
  2. Clean contaminated surfaces with disinfectant or bleach solution (5-25 tablespoons of household bleach per gallon of water).
  3. People with diarrhea should not prepare food.
