Health Information For Parents
Adenoviruses are a group of
that can infect the membranes (tissue linings) of the:
Adenoviruses are common causes of fever and illnesses such as:
Adenovirus (add-eh-noe-VY-rus) infections are usually mild, but serious infections can happen. Infants and people with weak immune systems are more likely to have severe problems. Some types of the virus are linked to more severe disease.
Adenovirus infections can affect children of any age. But they’re more common in babies and young children. Most kids have had at least one adenovirus infection before age 10. There are many different types of adenoviruses, so people can have more than one adenovirus infection.
Adenovirus infections can happen at any time of the year.
The symptoms of adenoviral infections depend on the type of adenovirus and the part of the body affected. Respiratory symptoms are most common.
Upper respiratory infections can range from mild cold symptoms to flu-like symptoms. These include:
Adenoviruses can also cause lower respiratory infections such as bronchiolitis, croup, or pneumonia. Adenovirus can cause a cough that sounds like whooping cough (pertussis).
Gastroenteritis is an infection of the stomach and intestines. Symptoms include diarrhea, vomiting, belly pain, and fever.
Bladder infections: These can cause frequent peeing, burning, pain, and blood in the urine.
Nervous system infections:
Adenovirus is highly contagious. Infections are common in close-contact settings, such as childcare centers, schools, hospitals, and summer camps.
Adenovirus can spread through droplets when someone with an infection coughs or sneezes. Fecal material (poop) can spread the infection via contaminated water, dirty diapers, and poor hand washing. Outbreaks of pharyngoconjunctival fever at summer camps are linked to contaminated water in swimming pools and lakes.
A child might also pick up the virus by touching someone who has it. Adenoviruses can survive on surfaces for a long time. So they can spread on contaminated toys, towels, and other objects.
Symptoms usually start 2 days to 2 weeks after contact with adenovirus.
The symptoms of adenovirus infections are similar to many other infections. If a person has a serious infection, doctors can test respiratory or conjunctival secretions, a stool sample, or a blood or urine sample to confirm the diagnosis.
Doctors will also test for adenovirus during suspected outbreaks. (An outbreak is when many people come down with the same symptoms.)
Most adenovirus infections get better on their own. Treatment at home includes getting plenty of rest, drinking enough liquids, and using acetaminophen to treat fevers. Babies and children with vomiting and diarrhea who can’t drink enough liquids may need treatment for dehydration.
Infants (especially newborns and premature babies), people with weak immune systems, and healthy children and adults with severe adenovirus infections may need antiviral medicine and treatment in a hospital. Other treatment, depending on the symptoms, may include intravenous fluids, oxygen, and breathing treatments.
Most adenovirus infections last from a few days to a week or two. Severe infections may last longer and cause lingering symptoms, such as a cough.
To help prevent the spread of adenovirus infections, parents and other caregivers should:
Call your doctor if your child is sick and:
You know your child best. If he or she seems very ill, call your doctor right away.
