Show Measles (Cases in 1996 in Utah =118) For seven of the last 14 year, Utah reports little to no incidence of measles. However, Utah and the nation had significant increases in measles rates for the years 1989, 1990 and 1991. In 1991 the number of measles cases reached the highest level since 1971. The most prevalent age group to contract measles in 1991 were those ages 5-19. From 1980 until 1988 it appeared that measles may have been contained. A national and statewide resurgence and subsequent decline in cases was then seen between 1988 and 1992. Measles had significantly high rates in 1994 and 1996. Two factors in the state have lead to the highest rates in the nation. First, Utah has lower vaccination rates than the rest of the U.S. Second is the size of Utah's families. As one member of the family becomes infected, the disease spreads to those who have been vaccinated but not fully protected by the vaccination. In 1995, Utah and the U.S. had no cases of measles. This is probably explained by higher vaccination rates. Measles primarily affects younger populations (age 19 or younger). However, since 1988, older individuals have made up to 10% of the total measles incidence. Table 57.
