Whooping cough used to be quite common in the United States. However, with the creation of a vaccine it is better controlled now. Every two to four years, outbreaks occur among people who are not immunized. Many cases occur among young children who have not received the entire series of vaccinations.

Reported cases of pertussis (whooping cough) vary from year to year and tend to peak every three to five years. More than 48,000 cases of pertussis were reported across the United States during 2012, including 20 deaths. The majority of deaths occur among infants younger than 3 months of age.
