Adenoviruses are common viruses that can cause illness in humans. But, most illnesses are not serious. Adenoviruses most often cause respiratory illness. The viruses may also cause fever, diarrhea, pink eye (conjunctivitis), bladder infection (cystitis), or rash illness.

Anyone can get infected with adenoviruses. Infants and people with weakened immune systems or existing respiratory or cardiac disease are at higher risk of getting sick from an adenovirus infection. You can get infected with adenoviruses by having close contact with people who are infected these viruses or those who are sick. You can also get infected by touching surfaces or objects that have adenoviruses on them then touching your mouth, nose, or eyes.
