Clinical Information

You may have choking spells or may cough so hard that you vomit. Anyone can get whooping cough, but it is more common in infants and children. It’s especially dangerous for infants. The coughing spells can be so bad that it is hard for infants to eat, drink, or breathe. To make a diagnosis, your doctor may do a physical exam, blood tests, chest x-rays, or nose or throat cultures.before there was a vaccine, whooping cough was one of the most common childhood diseases and a major cause of childhood deaths in the United States Now most cases are prevented by vaccines.
