Understanding Tuberculosis (TB): Silent Killer You Must Not Ignore
Tuberculosis (TB) is a highly contagious bacterial infection caused by Mycobacterium tuberculosis. While it primarily affects the lungs, TB can also impact the brain, spine, and kidneys. Despite being preventable and curable, TB remains one of the top 10 causes of death worldwide, with over 10.6 million new cases and 1.3 million deaths reported globally in 2023 alone, according to the World Health Organization (WHO).
🔬 What Is TB and How Does It Spread?
TB is transmitted through airborne particles released when an infected person coughs, sneezes, or even talks. You don't need direct contact—just breathing in the bacteria is enough.
However, not everyone infected becomes sick. TB has two forms:
- Latent TB: The bacteria remain in the body in an inactive state and cause no symptoms.
- Active TB: The bacteria multiply, causing symptoms and making the person infectious.
📊 Key Global Statistics (2023)
- 10.6 million people developed TB globally
- 1.3 million deaths occurred due to TB
- India, China, and Indonesia account for 50% of all TB cases
- Only 60% of TB patients complete their full course of treatment

If you are experiencing any of these symptoms, it is crucial to consult a doctor. TB is treatable—but only when diagnosed early.
👨⚕️ Expert Insight
