Illinois Tuberculosis Control Report 2002-2006 Introduction Tuberculosis (TB) is a reportable disease in Illinois (suspect and confirmed cases). The sooner cases are reported to the local TB control authority, the sooner their personnel can begin investigations which may interrupt transmission of TB in the community. Delays in reporting may contribute to the spread of TB. The U.S. Centers for Disease Control and Prevention (CDC) has set national objectives to guide elimination of TB in the United States. Progress has been made toward meeting these objectives in Illinois (Table A1). In 2006, Illinois reported 569 TB cases and ranked fifth in the United States among states for the total number of cases reported (California 2,781; Texas 1,585; New York 1,274; and Florida 1,038).This is the first year in Illinois reporting history that the number of foreign-born TB cases (54%) outnumbered the U.S.-born TB cases. The incidence of TB reported by local Illinois TB authorities ranges from very low incidence (<1 case per year) of disease in rural counties, to high incidence (>400 cases per year) in the Chicago metropolitan area. The Illinois Department of Public Health TB Program is responsible for statewide surveillance, management of the Illinois TB case registry, and oversight of TB prevention and control activities conducted by local TB control authorities (local programs). The program continues to work with local TB control authorities to ensure accurate and timely reporting of the disease in Illinois. Surveillance data is used to direct public health efforts to identified high risk groups and geographic locations. Section staff assists local programs through the provision of Directly Observed Therapy (DOT) grants, assessment and identification of local problems, planning appropriate interventions, assistance with outbreaks, orientation and training of local staff, and promoting and facilitating networking with other programs. This report provides an overview of statewide TB morbidity. For more detailed information on the TB incidence for Illinois jurisdictions and the city of Chicago please refer to the following resources: National level detailed surveillance reports can be obtained from the CDC at: Division of Tuberculosis Elimination - Surveillance Reports Detailed surveillance report for the city of Chicago can be obtained through: Chicago Department of Public Health, TB Program Web Site CDPH TB Morbidity Reports

Executive Summary This is the first time in nine years that Illinois has observed an increase in the total number of tuberculosis (TB) cases (Figure 1). During 2006, a total of 569 TB cases were reported, representing a decrease of 3.6 percent from the 596 cases reported in 2005. The 2006 case rate for Illinois is 4.4 cases per 100,000 population, which remains below the 2006 national rate of 4.6 per hundred-thousand population. In 2006, the Suburban Cook County TB Sanitarium District reported 116 TB cases, 69 percent of which were foreign-born, compared 64 percent of which were foreign-born, reported in 2005 (Table 1 and Table A3). In 2006, the highest numbers of foreign cases were from three countries: India, Mexico and the Philippines. (The Suburban Cook County TB Sanitarium District reports cases from Cook County, outside the city of Chicago.) The Chicago TB Program reported 292 TB cases in 2006 compared with 333 cases in 2005, representing a decrease of 12.3 percent. The number TB cases reported among the foreign-born increased 23 percent from 101 in 2005 to 131 in 2006. The U.S.-born black non-Hispanic group continues to report the largest decrease of 26 percent from 154 in 2005 to only 114 cases in 2006. Between 2002 and 2006, Chicago did observe a 23.9 percent decline in number of cases and the rate of TB decreased from 13.3 per 100,000 population in 2002 to 10.8 cases per 100,000 population in 2006 (Figure A1 and Table A2). The decrease of cases in Chicago and suburban Cook County was offset by an increase in cases of 11.6 percent reported in Illinois outside of Cook County (Table 1). The largest increase of cases outside of Cook County was reported in the U.S.-born African American non-Hispanic population, which increased from 14 cases in 2005 to 21 cases in 2006. DuPage County reported the largest increase in the number of cases from 29 cases in 2005 to 44 cases in 2006. In 2006, 53.6 percent (N=305) cases were foreign-born, coming from 52 countries. Mexico (N=86), India (N=55) and the Philippines (N=39) which accounted for 60.0 percent of all foreign-born cases reported (Figure 2). The percentage of foreign-born cases increased from 23

percent (N=224) in 1997 to 54 percent (N=305) in 2006 (Figure 3). Among cases reported in 2006 within Illinois and outside of Chicago, 63.4 percent (N=175) were foreign-born. Among the total cases reported between 2002 and 2006, 35.1 percent were black non-Hispanic, 24.3 percent Hispanic, 24.0 percent Asian and 15.7 percent white non-Hispanic. During this same period, the percentage of cases reported among the Asian population increased slightly 1.3 percent, whereas the rates among the black non-Hispanic, Hispanic and white non-Hispanic populations decreased 32.3, 6.3 and 4.4 percent respectively. In 2006, the non-Hispanic black group reported the largest number of cases (N=186) among all the race/ethnicity categories (Table A4). Illinois demographic data shows that, from 2002 to 2006, the highest percentage (34.1 percent), was reported among the 25- to 44-year-old age group, whereas the highest rates per 100,000 persons was recorded among the 45 to 64 and 65 and older age groups (Tables A6 and A7). During this same period, cases were divided 59.3 percent male to 40.7 percent female. The rate of cases 18 to 64 years old reporting to be unemployed in the past 24 months increased from 38.5 percent in 2002 to 44.7 percent in 2006. Examining race and ethnicity data among cases reported in 2006 by region of the state yielded considerable differences. For example, in 2006 among the 184 cases African-American non-Hispanic TB cases reported, 71 percent were reported within Chicago and only 29 percent were outside of Chicago (Table A5). Among all cases reported in 2006, 65.4 percent (N=372) were pulmonary only, 27.4 percent (N=156) extra-pulmonary and 7.2 percent both (N=41). Following initial drug susceptibility testing one multi-drug resistant (MDR) case and no extensively drug-resistant TB (XDR-TB) cases were reported (Table A8). Between 2002 and 2006, there were 1,036 TB cases ages 25 to 44. Of these, 77.9 percent (N=807) reported a valid HIV status (positive, negative or indeterminate) and 11.7 percent (N=121) were HIV-positive. During this five-year period, reporting of HIV status for TB cases in this age group improved from a low of 69.5 percent in 2002 to a high of 89.1 percent in 2006 (Table A10). For all ages during the five-year period, the total number of HIV positive TB cases was 204 (6.7 percent). Among the 7,917 AIDS cases reported to the Illinois Department of Public Health (IDPH) during 2002-2006, TB (pulmonary and/or extra-pulmonary) was diagnosed in 194 (2.5 percent) of the cases.
