Inactive TB and active TB disease
TB is caused by bacteria and commonly affects the lungs, although other parts of the body can be affected. People with inactive TB (latent TB infection) have no symptoms and cannot spread it. Inactive TB can develop into active disease. Active disease may cause illness and, when it affects the lungs or throat, can spread through the air.
When to ask about evaluation
A cough lasting three weeks or longer, chest pain, coughing up blood or sputum, fever, night sweats, fatigue, or unexplained weight loss can be symptoms of active TB. These symptoms also occur with other conditions. Contact a healthcare provider for evaluation; this website cannot determine whether you have TB.
Treatment is a clinical plan
Both inactive TB and active TB disease can be treated. Treatment duration varies by regimen and the person’s clinical circumstances. Complete the medicines as directed by the healthcare team and discuss any difficulty continuing treatment with them. Drug-resistant TB requires specialist care.
Care and practical support belong together
If transportation, housing, food, income, or language access makes treatment difficult to follow, tell your care team and ask about local resources. Our next-step guide points to established health-department and community resource directories.
