After experiencing major outbreaks of measles (rubeola) in 1986 and 1991, the incidence of the disease has decreased greatly. Though the number of cases rose in 1994 as a result of a college outbreak, it quickly returned to a very low level in 1995 and remained there through 1997. It appears likely that the objective will be achieved by the year 2000.

The incidence rate of verified tuberculosis (TB) in the total population increased steadily from 1986 through 1991, and then began a steady decline through 1997. The same is true for minorities; the peak came in 1992 for that population. In 1997, for the first time, the rates have gone below their 1986 levels. During the entire twelve year period, the incidence rate of TB for the minority population has been more than three times that of the total population. It is unlikely that either TB objective will be achieved.

Since 1988, the annual incidence of Lyme disease (with rash) has increased over 200 percent, with only a slight decline in 1997. The number of cases has consistently far exceeded the year 2000 objective. This has occurred despite prevention education and tick control efforts throughout the state. It is doubtful that the year 2000 objective will be reached.
