Tuberculosis (TB) is caused by a bacterium called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but TB bacteria can attack any part of the body such as the kidneys, spine, and brain. Not everyone infected with TB bacteria becomes sick. As a result, two TB-related conditions exist: latent TB infection (LTBI) and TB disease. People with TB infection do not feel sick, do not have any symptoms, and cannot spread TB. However, if untreated, they may develop TB disease and be able to spread TB disease to others.

People with TB disease can be treated and cured if they seek medical help.  Even better, people who have TB infection but are not yet sick can take medicine so they will never develop TB disease.

Marathon County Health Department works to identify, treat, and prevent the spread of TB disease in Marathon County.  Marathon County Health Department’s TB prevention and control activities include screening and testing of people that are at high risk for having TB infection. Marathon County Health Department follows up with people who have latent TB infection and people with active TB disease. The public health nurses protect the public by assuring treatment, investigating contacts, and isolating as necessary.
