Tuberculosis (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.
Don't find out from the news. Track this outbreak and 200+ diseases in real time.
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.
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

The Indian Council of Medical Research's drone-assisted transport of tuberculosis (TB) sputum samples initiative significantly improved access to diagnostic services, with the median turnaround time for TB diagnosis decreasing from 15 days to 5 days for people living in remote and underserved areas.
The assessment of its flagship i-DRONE initiative also showed there was significant reduction in out-of-pocket-expenditure of patients on transportation.
The findings emerged from a programme-based

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.
The approach marks a shift from waiting for patients to seek medical care to actively searching for those most at risk. "Finding missing TB patients requires proactive identification. AI can help public health sy
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.

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

17% of silicosis and TB claims have been paid out as of 30 June The Tshiamiso Trust has paid out R2.7-billion in compensation to gold mineworkers who died from or became ill with silicosis and TB from working in South African mines. The R5-billion trust was established in 2020 following a landmark class action settlement with six gold mining companies.

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.
Tuberculosis rates in England are at a ten-year high, with 9.4 cases per 100,000 people in 202

Imagine you hire someone to do a job, but they're very bad at it, getting less than half of what you expect done. You want to replace them but can't find anyone better, and then you slowly notice that, while they're pretty terrible at the job you hired them for, they're great in other ways. Indeed, it seems the employee you thought a dud held the workplace together by doing a small but significa
