There are many sources for getting tuberculosis, including people who are infected with the bacteria and spread it by sneezing, talking, or coughing. Other sources include certain types of birds such as chickens and animals, especially cattle. It can affect many parts of the body, but it most often affects the lungs and is characterized by the formation of nodules and cavities within the lungs. TB affects all ages. If the person with TB is being treated for the infection and is taking their medication, they can not spread the disease.
Symptoms can begin anytime from two months to several years after being exposed.
The treatment for TB may require a combination of several medications and it takes at least 6 months of treatment with follow up treatment over a period of time. Recently, certain types of TB have become resistant to medications. Those who work in prisons, hospitals, and long term care facilities should be tested yearly. Check with your healthcare provider to find out how often you should be tested. If you have been exposed or if you develop active TB disease, be sure to take all your medications as ordered until they are all gone.
