Which is the MOST likely etiology of an Adenoviral conjunctivitis?

• A. GI infection
• B. Upper Respiratory Infection
• C. Trauma
• D. Idiopathic

Answer: (B)

Adenoviral conjunctivitis is most strongly linked to an upper respiratory infection. Adenovirus frequently travels with or follows a cold-like illness, and outbreaks of conjunctivitis occur alongside pharyngitis, fever, cough, and other URI symptoms. The virus spreads through respiratory droplets and contaminated surfaces, so a recent or concurrent URI is the best contextual clue for this conjunctivitis. While adenovirus can cause gastroenteritis, that GI link is not what commonly drives the conjunctival infection, and trauma or an idiopathic label don’t explain the viral conjunctivitis pattern. Therefore, an upper respiratory infection is the best fit for the typical etiology.
