Whooping cough (pertussis) is a highly contagious respiratory tract infection. In advanced stages, it's marked a severe, hacking cough followed by a high-pitched intake of breath that sounds like "whoop."

In the first half of the 20th century, whooping cough was a leading cause of childhood illness and death in the United States. But after the introduction of a vaccine, the number of cases gradually declined, reaching a low in the mid-1970s.

Since then, however, the incidence of whooping cough has been increasing, primarily among children too young to have completed the full course of vaccinations and teenagers and adults whose immunity has faded.
