Tuberculosis in Black/African American Populations

Since 1993, the rates of TB in the United States have declined in almost all racial and ethnic groups. Rates of TB in non-Hispanic* blacks/African Americans have been cut in half (from 9.4 cases per 100,000 persons in 2007 compared to 4.7 in 2017) over the past decade.

However, black/African American populations in the United States continue to have a disproportionately higher burden of TB.

Addressing the TB disparity among blacks/African Americans is an important priority; prevention and control efforts should be targeted to this population.

The Numbers

In 2017, U.S. state, local, and territorial health agencies reported 9,105 TB cases to CDC.

  • TB disease was reported in 1,910 non-Hispanic blacks/African Americans in the United States, accounting for 21% of all people reported with TB nationally.
  • Among U.S.-born people reported with TB disease, 37% were non-Hispanic blacks/African Americans.
    • Both of these proportions are high considering black/African Americans make up only 13% of the U.S. population.
  • The rate of TB disease in non-Hispanic blacks/African Americans was 4.7 cases per 100,000 population, which is over nine times higher than the rate of TB disease in white, non-Hispanic people (0.5 cases per 100,000 population).

Prevention Challenges

TB is a challenging disease to diagnose, treat, and control. Dwindling resources and loss of public health capacity, including access to care and maintaining clinical and public health expertise add to the challenge. It is critical to reach those at highest risk for TB, and to identify and implement innovative strategies to improve testing and treatment.

TB rates are higher for some racial and ethnic groups. Like other communities, blacks/African Americans may face a number of challenges that contribute to higher rates of TB. Challenges include:

  • Treatment duration and completion
      • Treatment for TB disease is lengthy. Patients are often unable or reluctant to take medication for several months. For people with TB disease, inadequate treatment can lead to treatment failure, relapse, ongoing transmission, and development of drug resistance.
      • For people with latent TB infection, seeking and completing treatment for a condition with no symptoms of illness is often not a priority.
  • Socioeconomic factors
      • Poverty, including limited access to quality health care, unemployment, housing, and transportation can directly or indirectly increase the risk for TB disease and present barriers to treatment of this disease.
      • Language and cultural barriers, including health knowledge, stigma associated with the disease, values, and beliefs may also place certain populations at higher risk. Stigma may deter people from seeking medical care or follow up care.
  • HIV and other medical conditions
    • TB remains a serious threat, especially for people who are infected with human immunodeficiency virus (HIV). People infected with HIV are more likely than uninfected people to get sick with other infections and diseases, including TB.
      • Blacks/African Americans have the most severe burden of HIV of all racial/ethnic groups in the United States. Compared with other races and ethnicities, Blacks/African Americans account for a higher proportion of HIV infections at all stages of disease—from new infections to deaths.
      • Blacks/African Americans accounted for an estimated 43% of all new HIV infections among adults and adolescents (aged 13 years or older) in 2017, despite representing only 13% of the U.S. population.
      • Without treatment, as with other opportunistic infections, HIV and TB can work together to shorten the life of the person infected.
    • In addition to HIV, other underlying medical conditions may increase the risk that latent TB infection will progress to TB disease. For example, the risk is higher in people with diabetes, substance abuse (including injection of illegal drugs), silicosis, or those undergoing medical treatments with corticosteroids.
  • Delayed diagnosis
    • Delayed detection and diagnosis of TB disease, as well as delayed reporting of TB disease remains a challenge in TB prevention and treatment. Because the number of TB cases in the United States is declining, there is decreased awareness of TB signs and symptoms among health care providers and at-risk populations. Patients may be less likely to seek medical care and health care providers may be less likely to consider TB as the cause.
