Which of the following has a greater likelihood of being present in a child with laryngotracheobronchitis (croup) than in a child with epiglottitis?
Croup is a viral illness most commonly attributed to the following infectious agents:
Croup, the most common infectious cause of stridor in children, generally begins as an upper-respiratory tract infection one to three days before airway obstruction is noted. The child, usually aged 3 months to 5 years, presents with inspiratory stridor accompanied by a cough often described as resembling the barking of a seal. Older children may complain of a sore throat, but it is generally mild in nature. Physical examination reveals slight tachypnea (usually without retractions), a normal voice or some degree of hoarseness, rhinitis and a posterior pharynx that is mildly inflamed but may appear normal. Fever, if present, is generally low grade.
