Tuberculosis

Overview

Tuberculosis (TB) is a potentially serious infectious disease caused by the bacterium Mycobacterium tuberculosis. It primarily affects the lungs but can also affect other parts of the body. TB spreads through the air when an infected person coughs or sneezes, releasing tiny droplets containing the bacteria.

Symptoms

Common symptoms of TB include persistent coughing, chest pain, coughing up blood, fatigue, weight loss, fever, and night sweats. However, some people with TB may not experience any symptoms at all.

Treatment

TB is treatable with antibiotics, but it requires a long course of treatment to fully eradicate the bacteria from the body. Treatment typically lasts for six to nine months, and it’s crucial to complete the entire course of antibiotics to prevent drug-resistant strains from developing.

Prevention

Preventive measures for TB include vaccination, good ventilation in living and working spaces, and avoiding close contact with infected individuals. In addition, early detection and treatment of TB cases can help prevent the spread of the disease.
