Current Trends Tuberculosis -- United States 1981

A total of 27,412 cases of tuberculosis were reported to CDC in 1981. This figure, considered a provisional total until final corrected data for 1981 are received by the Tuberculosis Control Division, represents a decrease of 2.0% (571 cases) below the 1980 provisional total. The 1981 provisional case rate is 12.0/100,000 population, 3.2% lower than in 1980. However, the 1980 provisional data were based on a 53-week epidemiologic year, while the 1981 data cover a 52-week period (1). Based on these provisional numbers, the final tuberculosis case count for 1981 is expected to be comparable to that for 1980.

Before 1979 the number of tuberculosis cases decreased at a mean annual rate of 4.2%. In 1979 the decrease was 3.0%, and in 1980, the number of cases increased 0.3%. The provisional data for 1981 suggest that the secular trend that was previously downward, has leveled off. Reported by Tuberculosis Control Div, Center for Prevention Svcs, CDC.
