🌏WORLD TUBERCULOSIS DAY- 24th March

Yes! We Can End TB: Led by Countries, Powered by People

Every year on the 24th of March, the world marks World TB Day- day dedicated to raising awareness about one of the oldest yet still deadliest infectious diseases: tuberculosis (TB).

The theme for World TB Day 2026 “Yes! We Can End TB: Led by countries. Powered by people” is more than just a slogan. It is a bold call for hope, urgency, and accountability. It reminds us that while governments must take the lead, the power to end TB ultimately lies in the hands of people and communities.

Understanding Tuberculosis

Tuberculosis is an infectious disease caused by bacteria that primarily affect the lungs but can also spread to other parts of the body.

It spreads through the air when an infected person coughs, sneezes, talks, sings, or laughs.

However, only individuals with active lung (pulmonary) TB are contagious. In most cases, prolonged or close contact is required for transmission.

Interestingly, not everyone exposed to TB becomes sick. Many people are able to fight off the bacteria, preventing it from growing. This leads to latent TB infection, where the bacteria remain inactive in the body without causing symptoms.

Types of Tuberculosis

Tuberculosis (TB) exists in different forms depending on how it behaves in the body and how it responds to treatment.

1. Pulmonary Tuberculosis

- Affects the lungs

- Main form that spreads from person to person

- Symptoms include persistent cough, chest pain, and sometimes coughing up blood

2. Extrapulmonary Tuberculosis

- Occurs outside the lungs

- Can affect lymph nodes, spine, brain, or kidneys

- Generally less contagious

3. Latent Tuberculosis

- Bacteria are inactive in the body

- No symptoms

- Not contagious

- Can become active later if immunity weakens

4. Active Tuberculosis

- Bacteria are active and multiplying

- Symptoms are present

- can spread to others

5. Drug-Sensitive Tuberculosis

- Responds well to standard treatment

- Easier to manage

6. Drug-Resistant Tuberculosis

- Does not respond to common TB drugsn

- Includes MDR-TB and XDR-TB

- Requires longer and more complex treatment

Signs and Symptoms of Tuberculosis (TB)

Tuberculosis mainly affects the lungs (pulmonary TB), but it can also affect other parts of the body. The symptoms can develop slowly and may be mild at first.

Common Symptoms (especially pulmonary TB)

- Persistent cough lasting more than 2–3 weeks

- Coughing up sputum (sometimes mixed with blood)

- Chest pain, especially when breathing or coughing

- Fever (usually low-grade, often in the evening)

- Night sweats (waking up with soaked clothes or bedding)

- Unexplained weight loss

- Loss of appetite

- Fatigue and weakness

Symptoms of Severe or Advanced TB

- Coughing up blood (hemoptysis)

- Difficulty breathing

- Severe chest pain

Symptoms When TB Affects Other Parts of the Body (Extrapulmonary TB)

- Spine (Pott’s disease): back pain, stiffness

- Lymph nodes: painless swelling (especially in the neck)

- Brain (TB meningitis): headache, confusion, neck stiffness

- Bones/joints: pain and swelling

- Kidneys: blood in urine

Symptoms may be mild early on, so people may ignore them.

TB can be active (showing symptoms and contagious) or latent (no symptoms, not contagious).

If someone has a cough lasting more than 2 weeks, especially with weight loss or night sweats, they should get tested as early as possible.

Risk Factors for TB Exposure

You may be at higher risk of exposure if you:

- Live or work in crowded environments such as prisons, shelters, nursing homes, and healthcare facilities

- Work in mycobacteriology laboratories

- Have lived in or traveled to high-burden regions like Africa, Asia, Eastern Europe, Latin America, the Caribbean, and Russia

- Have close contact with someone diagnosed or suspected to have TB

Who Is More Likely to Develop Active TB?

TB becomes active especially when the immune system is weakened.

You are at higher risk if you:

- Use intravenous drugs

- Have a weakened or immature immune system (e.g., babies and children)

- Have chronic illnesses such as kidney disease or diabetes

- Have undergone an organ transplant

Are receiving chemotherapy for cancer

The Global and National Reality

Despite being preventable and treatable, TB continues to affect millions of people globally, causing serious health, social, and economic consequences.

Even in low-incidence countries like Ireland, progress is not always consistent:

TB rates increased by 32% between 2023 (4.3 per 100,000) and 2024 (5.6 per 100,000)

In 2025, the rate remained at 5.5 per 100,000, with 285 reported cases

As a low-incidence country, Ireland is expected to meet the World Health Organization End TB Strategy target of an 80% reduction in TB cases between 2015 and 2030.

However, current data shows that more effort is needed, as the expected number of cases should have been far lower than what was recorded.

Ending TB Is Possible

The fight against TB is achievable.

Ending TB requires:

Strong leadership from governments

Investment in healthcare systems

Early diagnosis and proper treatment

Public awareness and education

Active community participation

Because while countries can lead, it is people who make the difference.

Final Thoughts

Tuberculosis is not just a disease, it is a public health challenge that reflects gaps in awareness, healthcare access, and living conditions.

As we mark World TB Day, let this message remain clear:

Ending TB is not just aspirational, it is achievable.

Together, with collective effort and responsibility

Yes, we can end TB!!!
