What is tuberculosis and how dangerous is it?

Tuberculosis (TB) is a bacterial infection that primarily attacks the lungs but can affect any part of the body. Without treatment, TB is fatal in about half of cases. Even with modern treatment, TB kills over 1 million people annually. Drug-resistant TB strains make treatment more difficult and dangerous.

How does tuberculosis spread?

TB spreads through the air when a person with active pulmonary TB coughs, sneezes, speaks, or sings, releasing bacteria-containing droplets. You can only get TB from someone with active disease in their lungs or throat. Close, prolonged contact (living or working together) poses the highest risk. You cannot get TB from touching surfaces, sharing food, or brief contact.

What is the difference between latent and active TB?

Latent TB means you're infected with TB bacteria but not sick and can't spread the disease. About 5-10% of people with latent TB develop active TB in their lifetime, especially if their immune system weakens. Active TB causes symptoms and can spread to others. Both conditions are treatable, but active TB requires more intensive, longer treatment.

Is there a vaccine for tuberculosis?

Yes, the BCG (Bacille Calmette-Guérin) vaccine is used in many countries where TB is common. BCG is effective at preventing severe TB in children (TB meningitis) but provides variable protection against pulmonary TB in adults. In the U.S., BCG is not routinely used due to low TB prevalence and variable effectiveness.

What is drug-resistant TB?

Drug-resistant TB occurs when bacteria become resistant to standard TB medications. Multi-drug resistant TB (MDR-TB) doesn't respond to at least isoniazid and rifampin, the two most powerful TB drugs. Extensively drug-resistant TB (XDR-TB) is resistant to even more drugs. These forms require longer treatment (18-24 months) with more toxic, expensive medications and have lower cure rates.

Where is tuberculosis most common?

TB occurs worldwide but is most prevalent in Southeast Asia, Africa, and the Western Pacific. Eight countries account for two-thirds of global TB cases: India, Indonesia, China, Philippines, Pakistan, Nigeria, Bangladesh, and South Africa. Check the live outbreak data above for current TB trends.

Qu'est-ce que Tuberculosis?

Tuberculosis is caused by the bacterium Mycobacterium tuberculosis. In 2022, 10.6 million people fell ill with TB, and 1.3 million died from the disease. One-quarter of the world's population is estimated to be infected with TB bacteria, though most have latent TB (not sick or contagious). TB is curable and preventable, yet it continues to claim lives, particularly in low and middle-income countries.

Symptômes

Persistent cough lasting 3+ weeks
Coughing up blood or mucus
Chest pain when breathing or coughing
Unintentional weight loss
Fatigue and weakness
Fever and night sweats
Chills and loss of appetite

Transmission

TB spreads through airborne particles when a person with active pulmonary TB coughs, sneezes, speaks, or sings. Prolonged, close contact with an infected person increases transmission risk. TB is not spread by touching, sharing food, or brief contact. Poor ventilation increases transmission risk.

Période de Contagiosité : People with active pulmonary TB can be contagious until treated for 2-3 weeks; latent TB is not contagious

Prévention

Early diagnosis and treatment of active TB cases
Treatment of latent TB infection to prevent progression
BCG vaccination in high-burden countries (protects children)
Good ventilation in indoor spaces
Respiratory hygiene (covering mouth when coughing)
Isolation of infectious TB patients until no longer contagious
Regular screening for high-risk populations
UV light or air filtration in healthcare settings
