Adenovirus
A large family of viruses that can cause respiratory illness, pink eye, or gastroenteritis.
Symptoms and what to notice
Fever, sore throat, cough, runny nose, pink eye, or diarrhea and vomiting, depending on the virus type.
How long can it last?
Often several days to about two weeks; severe illness can last longer.
How serious is Adenovirus?
Usually mild, but pneumonia and other severe complications can occur, especially in people with weakened immune systems.
Treatment and management
Usually rest, fluids, and symptom care. Severe cases need medical assessment; there is no routine adenovirus-specific antiviral treatment.
Is there a vaccine—and who should receive it?
A live oral vaccine against types 4 and 7 is used only for eligible U.S. military personnel, not the general public.
