Adenovirus refers to a group of common viruses that mostly affect younger children. Daycares and schools often have outbreaks of adenoviruses, which can cause respiratory symptoms (sinus or throat problems, cough) and gastrointestinal problems (diarrhea, vomiting). Illnesses are usually mild, but they can sometimes lead to serious problems — especially in babies.
Adenovirus infections are seen year-round. In winter, spring, and early summer, respiratory symptoms are more common. Gastrointestinal symptoms are seen year round, mostly in children younger than 4.
