A 1-year-old male was brought to the clinic in September because he developed fever, chest congestion, rhinorrhea, and a barking cough three days previously. There was no sputum production, nausea, or vomiting.
His medical history was significant only for recurrent otitis media. On examination he had a temperature. He was in no acute distress and had audible obstructive upper airway sounds. His throat was red. The initial impression was that he had croup. Specimens were sent for viral culture. His symptoms were relieved with the use of a humidifier at home. Ten days later a virus was identified from a nasopharyngeal specimen only after hemadsorption studies were done on the virus culture.
