Tuberculosis (TB) remains a significant health concern worldwide, particularly in high-burden countries. Although TB is preventable and curable, delayed diagnosis and lack of awareness continue to contribute to its spread. Below are clear, practical answers to the most frequently asked questions about tuberculosis.
What Is Tuberculosis?
Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis. It most commonly affects the lungs (pulmonary TB), but it can also involve lymph nodes, bones, spine, brain, and other organs.
How Does TB Spread?
TB spreads through the air when a person with active pulmonary TB coughs, sneezes, or speaks. Close and prolonged contact increases transmission risk. TB does not spread through sharing food, handshakes, or touching surfaces.
What Are the Symptoms of TB?
Common symptoms include a cough lasting more than three weeks, persistent fever, night sweats, weight loss, fatigue, chest discomfort, and sometimes coughing up blood. Symptoms may vary depending on the organ involved.
Is Tuberculosis Curable?
Yes, TB is completely curable with proper treatment. Standard therapy usually lasts at least six months. Completing the full course of medication is essential to prevent relapse and drug resistance.
What Is Drug-Resistant TB?
Drug-resistant TB develops when medications are taken irregularly or stopped early. It requires longer, more complex treatment. Strict adherence to therapy prevents resistance.
What Is Latent TB?
Latent TB means the bacteria are present but inactive. The individual has no symptoms and is not contagious. However, latent TB can become active if immunity weakens.
Who Is at Higher Risk?
Individuals with diabetes, HIV, malnutrition, chronic illnesses, smokers, and those living in crowded environments are at higher risk of developing active TB.
How Can TB Be Prevented?
Early diagnosis, complete treatment, proper ventilation, cough hygiene, and screening of close contacts are key preventive measures. Treating latent TB also reduces future risk.
How Can I Protect My Family If I Have TB?
Take medications regularly, follow medical advice, cover your mouth while coughing, ensure good airflow at home, and encourage household members to undergo screening if recommended.
When Should I See a Doctor?
Consult a healthcare professional if you have a persistent cough lasting more than three weeks, unexplained weight loss, prolonged fever, or night sweats. Early evaluation protects both you and those around you.
