1996

TUBERCULOSIS

Between 1986 and 1990, the number of new verified tuberculosis cases increased at an average rate of 7.8 percent per year, after implementation of a new, stricter case definition in 1985 by the Centers for Disease Control and Prevention. In 1991 and 1992, the number of cases stabilized and in 1993 began to decline (Figure C3). The number of cases declined to 912 in 1993, 855 in 1994, and 848 in 1995. The number of verified cases reported in 1996 decreased from the 1995 level by 28 cases, to 820. The 1996 incidence represents a 16.7 percent decline from the highest incidence reached in the past decade (984 cases in 1992) (Division of Communicable Diseases, 1998a).

Incidence Chart

Total cases of tuberculosis include verified cases plus any additional cases which do not meet the revised, stricter CDC definition. In 1996, there were a total of 1,091 diagnosed cases, a decrease of 11 cases from the 1995 incidence (Table C4). There were 42 deaths from tuberculosis in 1996, also a decline from the 51 tuberculosis deaths reported in 1995. The death rate fell from 0.6 to 0.5 deaths per 100,000 population.

Persons aged 25 through 54 accounted for almost three-fifths (58.5%) of all verified cases of tuberculosis in 1996 (Table C10). Slightly less than 60 percent of verified cases were male (59.6%) and over one-third were black (39.1%). The modal age group for black males and females with verified tuberculosis diagnosed in 1996 was 35 through 44 years (27.8% and 30.9% of cases, respectively). For white males, the most frequent age at diagnosis was 25 through 34 years (21.0%) and for white females, it was 65 years and over (32.6%).

Every county but Hunterdon reported verified cases of tuberculosis in 1996 (Table C11), although two other counties reported fewer than five cases (Warren and Cape May). Eight counties had slight increases in the number of verified cases of tuberculosis over 1995 levels (Camden, Cumberland, Hudson, Middlesex, Monmouth, Morris, Salem, and Sussex). The number of verified cases reported in Bergen County increased over the year by 51.4 percent, from 37 to 56, while the incidence of verified cases in Passaic County increased 35.9 percent from 64 in 1995 to 87 in 1996. A major decrease in verified tuberculosis cases occurred in Essex County which declined 29.1 percent from 251 reported cases in 1995 to 178 in 1996. Five counties (Bergen, Essex, Hudson, Middlesex, and Passaic) together accounted for two-thirds of the verified cases in 1996 (66.1%). Hudson County had the highest rate of verified tuberculosis cases in 1996 (26.0 per 100,000 residents). There were 11 verified cases of tuberculosis among transients and 30 in residents of institutions. Both of these figures were decreases from 1995 levels.
