  2. Tuberculosis (TB)

Tuberculosis (TB)

Tuberculosis (TB) is a contagious disease caused by bacteria called Mycobacterium tuberculosis. It primarily infects the lungs, although it can also affect other parts of the body such as the kidneys, spine, and brain. TB spreads through the air when someone with the disease coughs, sneezes, or speaks. Not everyone infected with the bacteria becomes sick; some people have latent TB, meaning they carry the bacteria without symptoms, and they cannot spread the infection to others.

Symptoms of active TB disease include a persistent cough that lasts for more than three weeks, chest pain, and coughing up blood or phlegm. People with active TB might also experience fatigue, weight loss, fever, and night sweats. Early diagnosis and treatment are crucial to effectively manage TB and prevent its spread. TB is treatable with a course of antibiotics, although treatment can take several months to complete.

Vaccination, such as the Bacillus Calmette-Guérin (BCG) vaccine, can offer protection against certain forms of TB and is often given to infants in countries where the disease is common. Public health measures and awareness are essential in controlling TB, especially in regions with high infection rates.
