Latent TB Infection
Not everyone infected with TB bacteria becomes sick. People who are not sick have what is called latent TB infection. People who have latent TB infection do not feel sick, do not have any symptoms, and cannot spread TB to others. But, some people with latent TB infection go on to get TB disease.
Active TB Disease
People with active TB disease can be treated and cured if they seek medical help. Even better, people with latent TB infection can take medicine so that they will not develop active TB disease.
Untreated active TB disease can spread to other parts of the body, where it can lead to serious or life-threatening complications.
If TB-infected people do not take their medicine as their doctor or nurse directs, the TB bacteria may become resistant to certain medicine.
TB is a communicable disease which medical providers are required by law to report to the Public Health Department. Learn about that process and the symptoms of the disease.
TB disease can be cured by taking several drugs for 6 to 12 months.
