Mycobacterial Infections
Mycobacterial infections, particularly tuberculosis, have historically had a significant impact on Black Americans. During the early 20th century, TB was a leading cause of death in Black communities, driven by poor housing conditions, limited access to care, and systemic neglect. Today, Black Americans continue to experience higher rates of TB compared to white Americans, and are more likely to be diagnosed at later stages of the disease. Disparities in access to screening, preventive treatment, and follow-up care contribute to worse outcomes. Stigma around TB can also delay people from seeking help. Addressing social determinants of health and improving access to early detection and treatment are key to reducing these disparities.
Mycobacterial infections are diseases caused by bacteria of the Mycobacterium family. The most well-known are tuberculosis (TB), caused by Mycobacterium tuberculosis, and leprosy, caused by Mycobacterium leprae. There is also a group called non-tuberculous mycobacteria (NTM) that can cause lung and skin infections, especially in people with weakened immune systems. These bacteria grow slowly and can be difficult to treat, often requiring long courses of multiple antibiotics. TB most commonly affects the lungs but can spread to other parts of the body. Early diagnosis and proper treatment are essential to prevent serious complications and the spread of infection.
