Inheritance and Genetics of Tuberculosis

Genetics of Tuberculosis:

There is evidence that genetic factors may affect susceptibility to tuberculosis and whether the infection becomes latent or not.

Genetics of Tuberculosis Tuberculosis is NOT a genetic disease. Tuberculosis is an infectious disease. In general, an infectious disease can be caused by a pathogenic organism (viruses, bacteria, fungi, worms, parasites) that can invade the body and cause infection. Some infectious diseases can be contagious between people while others are acquired from the person's surroundings but are not spread from one person to another.

Racial Patterns for Tuberculosis:

Racial Information for Tuberculosis: TB is the number one infectious disease killer in the United States. It is 13-times more common among Asian populations, especially those from Cambodia, China, Laos, Korea, India, Vietnam and the Philippines.

Racial Details for Tuberculosis: Minorities are affected disproportionately by TB: 54 percent of active TB cases in 1995 were among African-American and Hispanic people, with an additional 17.5 percent found in Asians. In some sectors of U.S. society, TB rates now surpass those in the world's poorest countries. Among African-American men in New York City aged 35 to 44, for example, 315 out of 100,000 had active TB in 1993, many times the national average of 9.8 cases per 100,000 people.

About inheritance and genetics:

Inheritance of Tuberculosis refers to whether the condition is inherited from your parents or "runs" in families. The level of inheritance of a condition depends on how important genetics are to the disease. Strongly genetic diseases are usually inherited, partially genetic diseases are sometimes inherited, and non-genetic diseases are not inherited.
