Answer

In the prevaccination era, pertussis (ie, whooping cough) was a leading cause of infant death. As a result of vaccination, however, the number of cases reported decreased by more than 99% from the 1930s to the 1980s. Nonetheless, because of many local outbreaks, the number cases reported in the United States increased by more than 2300% between 1976 and 2005. (See Epidemiology.) [3]
