Tuberculosis
10 Épidémie ActivesTuberculosis (TB) is a contagious bacterial infection that primarily affects the lungs but can spread to other organs. It remains one of the world's deadliest infectious diseases, second only to COVID-19 in recent years.
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.
SymptĂ´mes
- 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

New tool can predict TB death risk at diagnosis, says study

Researchers say the tool could help identify high-risk patients early and support efforts to reduce TB deaths.The tool, developed by researchers from the ICMR-National Institute of Epidemiology (NIE), Chennai, and the Tamil Nadu TB programme, uses basic clinical measurements routine

Five questions may be all it takes to identify TB patients who need urgent care
A simple five-question tool that requires no laboratory tests can help health workers quickly identify tuberculosis (TB) patients who are most likely to become severely ill and need urgent hospital care, according to a study published recently in BMJ Open.
Researchers found that the bedside assessment performed as well as the more elaborate triage information routinely collected under the national TB programme in preventing deaths. Its accuracy improved further when combined with basic patient d

Tuberculosis, India
India bears about 25% of the global TB burden, with ~2.8 million new cases annually despite a 21% incidence decline from 2015–2024, outpacing the global 12% drop, aided by Ni-kshay and TB Mukt Bharat Abhiyan (key pillars of India’s national initiative to eliminate) though challenges persist from MDR-TB, HIV co-infection, and regional hotspots like Mizoram's 145 deaths in 2025.
