Show MEASLES (Cases in 1992 in Utah=O) The incidence of measles decreased in Utah and the nation from 1951 to the 1980's. Measles appeared to be contained from 1981 through 1988, but then increased in both Utah and the nation (Table 56, Figure 34). The resurgence of measles is most likely due to low immunization rates of children under the age of two (see Public Health Section, p. 81) and primary vaccine failure. There does not appear to be any consistent trend in the Utah:U.S. comparison. The differences reflect the year-to-year variability in infectious diseases and the problems of comparisons based upon small numbers. The incidence of measles by age (Table 57) reveals that it principally affects younger populations (primarily those age 19 and younger). However, since 1989 there has been an increase in the number of older people infected with measles. From 1980 to 1988 there were very few cases in the 20 and over age group, but this age group accounts for nearly 10% of the cases from 1989-1991.
