A 3-year-old girl is brought to the physician because of a cough for 2 days. The cough occurs as paroxysmal spells, with vomiting sometimes occurring afterwards. She takes a deep breath after these spells that makes a whooping sound. She has been unable to sleep well because of the cough. She had a runny nose and low-grade fever 1 week ago. She was admitted at the age of 9 months for bronchiolitis. Her immunizations are incomplete, as her parents are afraid of vaccine-related complications. She attends a daycare center but there have been no other children who have similar symptoms. She appears well. Cardiopulmonary examination shows no abnormalities.
