Introduction: Why Tuberculosis Still Demands Our Attention
Every year on March 24, World Tuberculosis (TB) Day reminds us of a disease many assume is a relic of the past. But here’s the stark reality: TB remains one of the deadliest infectious diseases globally, claiming over 1.3 million lives in 2024 alone. Nigeria, unfortunately, is still among the top 10 countries burdened by TB, with an estimated 452,000 new cases reported in 2024 (WHO data).
As we mark World TB Day 2025under the theme “Yes! We Can End TB!”, it’s time to confront myths, arm ourselves with knowledge, and take actionable steps to combat this airborne killer.
Below, we break down ten essentially facts about TB—from prevention to treatment—and why your awareness matters now more than ever.
1. The BCG Vaccine: A Lifeline for Children
What you need to know:
The Bacillus Calmette-Guérin (BCG) vaccine, administered at birth in Nigeria, leaves that distinctive scar on your upper arm. While it doesn’t guarantee complete immunity, it’s 70-80% effective at preventing severe forms of TB in children, such as meningitis and miliary TB.
Why this matters in 2025:
Despite its limitations, the BCG vaccine remains a cornerstone of TB prevention. However, vaccine coverage gaps persist in rural areas due to logistical challenges. Advocacy for equitable healthcare access is critical to protect vulnerable populations.
2. TB Spreads in Crowded, Poorly Ventilated Spaces
The science behind transmission:
TB is caused by Mycobacterium tuberculosis, which spreads through airborne droplets when an infected person coughs, sneezes, or talks. Prolonged exposure in crowded environments (markets, public transport, homes) significantly increases infection risk.
Practical tip:
- Maintain 1-2 meters of distance from persistent coughers.
- Prioritize outdoor gatherings or well-ventilated spaces.
3. Masks Aren’t Just for Pandemics—They Fight TB Too
Revisiting mask etiquette:
While COVID-19 normalized mask-wearing, their role in TB prevention is often overlooked. In high-risk settings like hospitals, prisons, or IDP camps, wearing a well-fitted N95 mask reduces inhalation of infectious particles by up to 95%.
2025 update:
Nigeria’s National TB Control Program (NTBLCP) now distributes free masks in high-burden states like Lagos, Kano, and Rivers.
4. Boost Your Immunity: Your First Line of Defense
The immune-TB connection:
A weakened immune system (due to malnutrition, HIV, diabetes, or stress) makes you susceptible to TB. 1 in 3 TB cases in Nigeria is linked to HIV co-infection (UNAIDS 2024).
Strengthen your defenses
- Eat nutrient-dense foods (e.g., beans, leafy greens, eggs).
- Prioritize sleep (7-9 hours nightly).
- Manage stress through exercise or mindfulness.
5. Overcrowding Fuels TB—Know When to Stay Home
The risk of “super-spreader” events:
Nigeria’s bustling social culture—weddings, religious gatherings, parties—can inadvertently fuel TB transmission. If you have a persistent cough (2+ weeks), fatigue, or night sweats, stay home and seek testing.
Did you know?
A single untreated TB patient can infect **10-15 people annually.
6. Cough Hygiene: A Simple Act of Community Care
Do it right:
- Cough/sneeze into a tissue (dispose immediately) or your elbow.
- Avoid covering your mouth with hands—this spreads germs to surfaces.
- Wash hands with soap for 20 seconds afterward.
The bigger picture:
Small actions like these can reduce TB transmission rates by up to 50% in communities.
7. Early Diagnosis Saves Lives—Get Tested
Break the stigma, seek help:
A lingering cough isn’t “just malaria.” **TB is curable, but delayed diagnosis leads to drug-resistant strains (DR-TB), which are costlier and harder to treat.
8. Advocate for Contact Tracing & Household Screening
Why it works
TB often spreads within households or close communities. The World Health Organization (WHO) emphasizes that screening all close contacts of a diagnosed TB patient can reduce transmission by up to 40%.
Nigeria’s progress:
In 2024, the National TB Program (NTBLCP) launched door-to-door screening initiatives in high-burden states like Kano and Lagos. Over 12,000 latent TB cases were identified and treated early, preventing progression to active disease.
Action step:
- If someone in your household tests positive for TB, insist on free screenings for all family members.
- Community health workers (CHWs) can provide rapid testing kits in remote areas.
9. Preventive Therapy for High-Risk Groups
Who needs it:
Not everyone exposed to TB gets sick. However, people with latent TB infection (LTBI)—where bacteria remain dormant—have a 5–10% lifetime risk of developing active TB. Preventive therapy (PT) slashes this risk by 60–90%.
Priority groups for PT in Nigeria:
- HIV-positive individuals (risk of TB is 15–20x higher).
- Children under 5 exposed to TB.
- Healthcare workers in TB wards.
2025 update:
Nigeria now offers 3-month isoniazid-rifapentine regimens (3HP) instead of the traditional 6–9 month courses, improving adherence. Ask about PT at your nearest Primary Health Care (PHC) center.
10. Improve Indoor Airflow to Disrupt Transmission
The ventilation solution:
TB bacteria linger in stagnant air. Simple ventilation tweaks can cut infection risk:
- Open windows (even a 10cm gap increases airflow).
- Use exhaust fans in kitchens and bathrooms.
- UV germicidal irradiation (UVGI) systems in hospitals/buses kill airborne TB bacilli.
Where to get tested:
- Free services: Over 6,000 public health centers nationwide.
- Rapid molecular tests: Results in 2 hours (GeneXpert machines available in all states).
Why World TB Day 2025 Matters for Nigeria
Despite progress, challenges persist:
- Funding gaps: Global TB funding fell by $1.3 billion in 2024, threatening progress.
- Stigma: Many avoid testing due to fear of discrimination.
- Drug resistance: 18,000 Nigerians had DR-TB in 2024—a 22% increase from 2023.
What You Can Do Today
1. Get tested if you’ve had a cough for 2+ weeks.
2. Educate others: Share this article on social media.
3. Support advocacy: Demand increased government funding for TB programs.
Together, we can end TB.
