His symptoms began while he was away at summer camp. His immunizations are not up-to-date. He appears ill. His temperature is 39.1C 102.3F. Physical examination shows erythema and edema of the conjunctivae and posterior pharyngeal wall. There is bilateral, tender, preauricular lymphadenopathy. Further evaluation shows infection with a DNA virus. Which of the following is the most likely causal pathogen?? A: Adenovirus, B: Parvovirus, C: Picornavirus, D: Paramyxovirus, E: Human herpes virus 4,  <response>: This is a clinical vignette describing a 9-year-old boy with fever, sore throat, and red eyes after being at summer camp. His immunizations are not up-to-date. On exam he has conjunctivitis, pharyngitis, and tender lymphadenopathy. Further testing shows a DNA viral infection. The key findings here are the conjunctivitis, pharyngitis, lymphadenopathy, and DNA viral infection in an unimmunized child with recent summer camp exposure. This presentation is most consistent with adenovirus infection.Parvovirus typically causes Fifth disease, which would not cause conjunctivitis. Picornaviruses like enteroviruses can cause viral conjunctivitis but do not usually cause pharyngitis. Paramyxoviruses like parainfluenza can cause pharyngitis but not usually conjunctivitis. EBV causes mononucleosis but would not cause conjunctivitis.A: Adenovirus
