World TB Day Is March 24Th

March 24th has been designated World TB Day in order to raise awareness and support for worldwide TB elimination efforts. This annual event commemorates the date in 1882 when Dr Robert Koch announced his discovery of Mycobacterium tuberculosis, the bacterium that causes TB. TB has not disappeared – worldwide it still kills approximately a million people a year.
Fortunately, the rates in the United States have declined steadily since the 1990s, after a brief resurgence. In 2019, 8,916 individuals were diagnosed with active TB in the U.S. Of those cases, 66 were located in Kentucky and 3 were located in the Lake Cumberland District. Local health departments are responsible for ensuring TB patients receive treatment and people who may have been in close contact with these individuals are identified and tested.
TB most commonly affects the lungs, but can also cause infection of any organ of the body. One can become infected with TB by sharing living spaces with individuals who have active TB disease and are contagious; coughing contaminates the air with TB particles which may be inhaled by another person, who becomes infected. This infection can remain dormant (latent) for years and is non-contagious, but it can become active when an individual’s immune system weakens as can occur with advancing age, chronic diseases such as diabetes, use of immunosuppressant medication for rheumatoid arthritis or other autoimmune diseases or for cancer. Smoking can also increase the risk of TB activation.
On a separate note, it is important to point out that Kentucky is one of the unhealthiest states in our nation; but, a few healthy lifestyle choices could change this. First, eating normally proportioned helpings of nutritious foods including at least five fruits and vegetables a day can lower weight and reduce heart disease and diabetes. Second, exercising about 30 minutes per day can lower blood pressure. Third, avoiding the use of tobacco products can reduce several types of cancer. Finally, making sure you get your needed preventive screenings can detect diseases early and greatly increase your chances for a positive health outcomes, while receiving your recommended vaccinations can prevent acquiring disease in the first place.
