Overview
This disease results in high morbidity and mortality in many countries every year. In the United States, 5000-7000 cases are reported each year. Incidence of pertussis has increased steadily since the 1980s. The incidence in 2002 was 3.01/100,000 when 8,296 cases of pertussis were reported.
Trends in Pertussis Disease in the United States
In the United States, the highest recorded annual incidence of pertussis occurred in 1934 when greater than 260,000 cases were reported. The incidence of reported pertussis disease declined substantially in the 1940's as use of whole-cell DTP vaccines became widespread. By 1970, the reported incidence had declined greater than 99%; the fewest cases (1,010) were reported in 1976. However, since the early 1980s reported pertussis incidence has increased steadily. Cyclical peaks in incidence occurred in 1983, 1986, 1990, and in 1993. The number of reported cases has increased in all age groups, but the increase is greatest among persons aged greater than or equal to 5 years. Nevertheless, infants and young children continue to have the highest risk for pertussis and its complications.
Despite the availability of vaccination, the incidence of pertussis in the US has continued to increase in the past 10-15 years. The Center for Disease Control and prevention (CDC) reported the incidence of pertussis in 2005 to be 25,616, which is triple the incidence reported in 2001.
