Understanding tuberculosis symptoms, prevention, and treatment options.

Tuberculosis (TB) remains one of the world's most deadly infectious diseases. Understanding this condition is crucial for prevention and early treatment.

What is Tuberculosis?

Tuberculosis is a bacterial infection caused by Mycobacterium tuberculosis. It primarily affects the lungs but can spread to other parts of the body, including the kidneys, spine, and brain.

Recognizing the Symptoms

Common symptoms of active TB include: - Persistent cough lasting more than 3 weeks - Chest pain - Coughing up blood - Fatigue and weakness - Fever and night sweats - Unintentional weight loss

Prevention Strategies

Prevention is key in controlling TB spread. The BCG vaccine provides protection, especially for children. Proper ventilation, wearing masks in crowded places, and completing prescribed treatments are essential measures.

Treatment Options

TB is treatable and curable with proper medication. Treatment typically involves a 6-month course of antibiotics. It's crucial to complete the entire course to prevent drug-resistant TB.
