The most likely diagnosis is a viral illness acquired at the camp. The key features pointing towards a viral etiology are the acute onset of symptoms in a previously healthy child, exposure to other sick children at camp, and the clinical manifestations of conjunctivitis and pharyngitis. The main viral pathogens to consider are adenovirus, enterovirus, influenza, metapneumovirus, and rhinovirus. Adenovirus and enterovirus commonly cause pharyngoconjunctival fever with conjunctivitis, pharyngitis, and fever. Influenza can present similarly. Metapneumovirus and rhinovirus less commonly cause conjunctivitis. Based on the combination of conjunctivitis and pharyngitis following a camp exposure, the most likely diagnosis is adenovirus or enterovirus infection acquired at camp.E: Adenovirus
