    1997 Fact Sheet
    Tuberculosis in the Foreign Born

    1. In 1997, 19,855 cases of TB were reported in the United States. This represents a 7% decrease from 1996 (21,337 cases). Of these 19,855 cases, 7,702 (39%) were foreign born. These 7,702 cases represent essentially no change in the number of foreign-born cases nationally since 1996 (7,704). However, there has been a steady increase in foreign born-cases since the mid-1980s. Tuberculosis case rates among the foreign born are consistently four to five times higher than among U.S. born persons. 1
    2. In 1997, 4,059 cases of TB were reported in California. This represents a 6% decrease from 1996 (4,313 cases). Of these 4,059 cases, 2,815 (69%) were foreign born. These 2,815 cases represent a decrease of <1% in the number of foreign born cases since 1996 (2,843). Persons from Mexico, the Philippines, and Vietnam make up 66% (1,861) of the total foreign- born cases. 2
    3. In 1997, 1,347 cases of TB were reported in Los Angeles County. This represents a 2% decrease from 1996 (1,375 cases). Of these 1,347 cases, 963 (71%) were foreign-born. These 963 cases represent a 4% increase in the number of foreign born since 1996 (910). Cases were reported from 61 different foreign countries in 1997. Los Angeles County comprises 12% of the national foreign-born cases.
    4. Of the 963 foreign born TB cases, 350 (36%) were from Mexico, 166 (17%) were from the Philippines, 72 (7%) were from Vietnam, 69 (7%) were from South Korea and 50 (5%) were from China.
    5. More males with TB in the foreign-born population were reported than females. In 1997, 603 (63%) of the foreign-born cases were male and 360 (37%) were female.
    6. The age group with the largest number of reported foreign-born TB cases was the 15-34 year old age group with 292 cases (30%), followed by the 65+ age group with 225 cases (23%) and the 35-44 age group with 171 cases (18%).
    7. There were 37 (3%) homeless cases of TB among the foreign-born population reported in Los Angeles County in 1997. Twenty-eight of these cases were Hispanic from Mexico, Guatemala, and El Salvador. Of all homeless cases reported in 1997 (115 cases), 32% were foreign born.
    8. In 1997, there were 58 (6%) confirmed cases of TB co-infected with HIV among the foreign born. Forty-six (79%) cases were Hispanic from Mexico, Guatemala, and El Salvador.
    9. Seventy-eight percent (753) of foreign-born cases in 1997 were confirmed on the basis of a positive culture. This is comparable to the U.S. born population in which 73% of cases were confirmed on the basis of positive bacteriology.
