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

In the Indian context, research shows that a severely undernourished TB patient is four times more likely to die during treatment

Every year, more than 26 lakh Indians are diagnosed with TB. The conversation that follows is almost always about which drugs, for how long, and whether the strain is resistant. I have witnessed patients with an accurate diagnosis and drugs lose ground, week by week, because a body without adequate nutrition cannot fight this disease. We have shortened treatment regim

Artificial intelligence is beginning to address that gap. Working with state TB divisions, Wadhwani AI has developed two AI-powered tools that enable health workers to identify vulnerable populations and detect infections earlier, reducing the chances of the disease spreading unnoticed.

Doctors Warn Poverty Is Fueling Rising HIV Infections in Nigeria

Nigeria 2026-07-06
Active

bohlah at 5-07-2026 08:31 PM (4 mins ago) (m) Medical experts have linked the rise in new Human Immunodeficiency Virus (HIV) infections in Nigeria to declining donor funding, worsening poverty, and reduced awareness campaigns, warning that the trend could reverse years of progress in controlling the disease. According to the Federal Ministry of Health and Social Welfare's State of the Health of the Nation Report 2025, Nigeria recorded 102,025 new HIV infections across the 36 states and the Federal Capital Territory in 2025. The physicians said funding cuts have weakened HIV prevention programmes, testing services, counselling, education, and community support, while worsening economic hardship has increased the risk of HIV transmission.

A much-needed plan for TB in India

In March 2018, India made a surprising announcement in a full auditorium on World TB Day. India would eliminate tuberculosis by 2025. Five years ahead of the global target.

India did want to eliminate TB, but it was no easy task. Also, no one knew how or its cost. As we sit in mid-2026, with no elimination in sight, it's time to introspect and ask: What should we do for TB beyond 2025?

India, energised, has certainly made progress on TB-expanded diagnostics, digital tracking systems, nutritiona

One person a week dies from undiagnosed tuberculosis in England according to a new study which suggests health workers could be overlooking the disease.

Older British-born men were among those most likely to be diagnosed with TB only after death which should be considered a "never event", researchers say.
