There are over fifty types of this virus that can cause human infections. Different strains circulate at different times based on movements of people and immunity to these different strains. Some adenovirus strains may cause more severe illness than other strains. Patients with weakened immune systems, or existing respiratory or cardiac disease, are at higher risk of getting sick.
What are the symptoms of adenovirus?
Symptoms include common cold symptoms such as:
- Runny nose
- Sinus congestion
- Sore throat
- Pink eye
- Cough
Symptoms of more severe infection include shortness of breath, pneumonia, wheezing, chest pain, and fever.
Symptoms of gastroenteritis may include vomiting, diarrhea, and stomach cramps.
When do symptoms occur?
Symptoms of adenovirus usually occur three to five days after exposure.
How do I know if I have adenovirus?
See your health care provider. They may order lab tests to see if you are infected with an adenovirus strain.
The viruses spread in different ways depending on the type of infection and strain. Adenoviruses that cause respiratory and eye infections are spread by contact with an infected persons eyes, nose, or mouth. Adenoviruses that cause gastroenteritis are transmitted by contact with an infected person's feces (stool). You can also get infected by touching objects that have the virus on them and then touching your eyes, nose, or mouth.
Most infections are mild and require no treatment. Treatment focuses on relieving the symptoms, which may also go away on their own. Serious illnesses are managed by treating symptoms and complications of the infection. Several antiviral drugs have been used to treat serious infections, such as those caused by strain A14.
There is no vaccine for adenovirus therefore, good handwashing and respiratory etiquette are the best ways to prevent illness.
- Cough or sneeze into your upper sleeve, and throw away used tissues right away.
- Frequently and thoroughly wash your hands.
- Avoid touching your eyes, nose, and mouth with unwashed hands.
- Avoid close contact with those who are ill or exhibiting respiratory symptoms. Do not share cups and utensils with someone who is sick.
- Stay home if you are ill; children who are ill should not attend school or child care.
