Pharyngoconjunctival fever happens when adenovirus affects the lining of the eye and the respiratory tract.

Gastroenteritis is inflammation of the stomach and the intestines, large and small. Wet diarrhea, vomiting, headache, fever, and stomach cramps accompany this variety. Adenovirus is sometimes linked to urinary tract infections, which causes urinary frequency, burning pain, or blood in the urine. All types of adenovirus are transmitted by direct contact, fecal-oral and waterborne transmission. Some types can establish persistent infections in the tonsils, adenoids, and intestines.
