TUBERCULOSIS INSOUTH CAROLINA Shea Rabley, RN, MN, Director TB Control Division South Carolina Department of Health and Environmental Control
Tuberculosis, an airborne communicable disease caused by mycobacterium tuberculosis, is primarily found in the lungs (pulmonary) but the bacteria can attack and cause disease in any part of the body (extrapulmonary). Transmission occurs by the expectoration of droplets into the air from a person with active pulmonary disease and the subsequent inhalation of the aeroslized droplets by another person. This can occur while talking, singing, sneezing or coughing. General Information about Tuberculosis
Once a person is exposed and becomes infected, the TB bacilli can remain dominant in the body (latent TB infection or LTBI) or it can progress to active TB disease. LTBI progresses to active TB disease in ~10% of these persons within the first 2 years. The rest remain at risk for life. For persons with a weakened immune system from HIV, other medical conditions or drugs that affect the immune system, the risk of progression is increased greatly and this risk remains higher year after year than it does for others.
TREATMENT TB infection requires the use of 1-2 drugs for 6 – 9 months for treatment completion. TB disease requires treatment with 4 or more drugs for the initial 2 months and then 2 drugs for 4 – 7 more months for a total of 6 – 9 months. Drug resistant TB (MDR-TB or XDR-TB) requires treatment with sensitive drugs for 12 – 24 months.
