What is 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.

Symptoms

  • 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.

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

Prevention

  • 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
