Most commonly, viral conjunctivitis is due to adenovirus infection. Many serotypes may be involved. Types 3, and sometimes, 4 and 7, are responsible for pharyngoconjunctival fever - conjunctivitis associated with upper respiratory tract infection. Types 8 and 19 are frequent findings in viral keratoconjunctivitis.
