The Theme
The 2025 theme builds upon previous years’ messages, maintaining a consistent focus on hope, urgency, and accountability in the fight against TB.
By rallying global efforts under this theme, World TB Day 2025 aims to accelerate progress towards a TB-free world, ensuring health and well-being for all.
The year 2025 theme underscores a unified global call to action, emphasizing:
- Commit: Translating global leaders’ pledges from the 2023 UN High-Level Meeting into concrete actions, such as implementing WHO guidelines, enhancing national strategies, and ensuring full funding.
- Invest: Recognizing that eliminating TB requires substantial financial resources. There’s a need for diversified funding to bridge gaps in prevention, diagnosis, and treatment, and to foster research and innovation.
- Deliver: Transforming commitments into tangible results by scaling up proven WHO-recommended interventions. This includes early detection, diagnosis, preventive treatment, and high-quality care, especially for drug-resistant TB. Success hinges on community leadership, civil society action, and cross-sector collaboration.
Despite great progress, TB remains one of the top infectious disease killers worldwide, affecting millions, especially in developing countries. Observing World TB Day reminds us of the collective effort needed to eliminate tuberculosis and ensure a healthier future for all.
What is Tuberculosis (TB)?
Tuberculosis (TB) is a contagious bacterial infection caused by Mycobacterium tuberculosis. It primarily affects the lungs but can also spread to other organs like the brain, kidneys, and spine. TB spreads through airborne droplets when an infected person coughs, sneezes, or talks. Not all persons who get infected with TB bacteria, progress and develop TB diseases. Most of the time the TB infection gets locked up in the body by the immunity of the person. A person with this type of TB infection is not diseased and also does not spread to others. A patient with TB of the lungs only can spread the bacteria in droplets, which is also called an open case of Pulmonary TB.
Common Symptoms of TB:
Pulmonary TB (affecting the lungs)
- Persistent cough lasting more than three weeks
- Coughing up blood or mucus
- Chest pain
- Shortness of breath
- Unexplained weight loss
General Symptoms
- Fever and chills
- Night sweats
- Fatigue and weakness
- Loss of appetite
Extrapulmonary TB (affecting other organs)
- Swollen lymph nodes
- Joint or bone pain
- Meningitis (if it spreads to the brain)
Early diagnosis and treatment with proper anti-TB medicines can cure TB and prevent complications. If left untreated, it can be life-threatening.
The Global Burden of Tuberculosis
Tuberculosis (TB) remains a significant global health challenge, with recent data indicating both progress and ongoing concerns. As per estimates in the year 2023, approximately 10.8 million people contracted TB worldwide, this is an indication that there is a stabilization in new cases compared to previous years when there was an increase which was exacerbated by the COVID-19 pandemic. Despite this positive trend TB still is a challenge because it is a leading cause of death from a single infectious agent, surpassing COVID-19, with an estimated 1.25 million TB deaths in 2023
Tuberculosis Burden in India
As per the global report 2023 of the World Health Organization, the treatment coverage had improved to 80% of the estimated TB cases, an increase of 19% over the previous year. India’s efforts to ensure early detection and treatment initiation, along with a host of community engagement efforts has resulted in a decline of 16% in TB incidence (new cases emerging each year) and an 18% reduction in mortality due to TB, since 2015. There is a fall in the incidence rate of TB in India from 237 per lakh population in 2015 to 199 per lakh population in 2022 and the mortality rate has also declined from 28 per lakh population in 2015 to 23 per lakh population in 2022. These improvements in data parameters of TB are due to better availability of TB treatment facilities under the National TB Elimination Programme, in India and wider coverage of the country’s population for free treatment of TB.
In India, the estimated number of TB cases slightly decreased in 2023, but reported cases increased, indicating progress in closing diagnosis gaps and also improvement in TB notification rates. The country reported approximately 2.8 million TB cases in 2023, accounting for 26% of global cases. TB-related deaths in India were estimated at 315,000, representing 29% of global TB deaths.
History of World TB Day
World TB Day is observed every year on March 24th to raise awareness about tuberculosis (TB), a disease that has plagued humanity for centuries. The date was chosen to commemorate the groundbreaking discovery of the TB-causing bacterium, Mycobacterium tuberculosis, by Dr. Robert Koch on March 24, 1882. This discovery was a turning point in the fight against TB, as it provided the foundation for diagnosing and treating the disease.
The Significance of Dr. Koch’s Discovery (1882)
Before Koch’s discovery, tuberculosis was a major cause of death in Europe and the Americas, often called the “White Plague” due to the pale appearance of its sufferers. It was widely misunderstood and thought to be hereditary rather than infectious. Dr. Koch’s work proved that TB was caused by bacteria, laying the groundwork for future medical research and treatments, including antibiotics and vaccines.
The Establishment of World TB Day
- 1982: On the 100th anniversary of Dr. Koch’s discovery, the International Union Against Tuberculosis and Lung Disease (IUATLD) proposed observing March 24th as World TB Day to increase public awareness.
- 1996: The World Health Organization (WHO) and its partners formally recognized and promoted World TB Day as an official global health campaign.
- 2000s-Present: Since then, various health organizations, governments, and NGOs have been using this day to highlight TB’s impact, advocate for better healthcare policies, and promote research for its eradication.
Global Efforts and Progress
Over the decades, World TB Day has played a crucial role in:
✅ Spreading awareness about TB prevention and treatment.
✅ Advocating for universal healthcare access and funding for TB research.
✅ Encouraging early diagnosis and treatment adherence.
✅ Promoting initiatives like the WHO’s End TB Strategy, which aims to eliminate TB as a global health threat by 2030.
