Show PERTUSSIS (Cases in 1992 in Utah=45) There was a significant drop in the incidence of pertussis (whooping cough) between 1950 and 1990 (Table 59, Figure 36), attributed in part to better public health programs, including immunizations. Utah's rates followed this trend, but appear to be above the nation's rates for 6 of the last 10 years. Utah's rate is affected by the number of children in the population since incidence of pertussis is greatest among infants under the age of one, followed by pre-schoolers, and finally school-aged children (Table 60). The Utah:U.S. ratio shows that Utah has varied substantially in its comparison with the U.S. There is no apparent trend in how Utah and the U.S. compare. The changes reflect the small number of cases and the year-to-year variability of the incidence of this disease.
