Tuberculosis (TB) is a serious bacterial infection that mainly affects the lungs. It’s still a big health problem, and Nigeria is one of the countries with the highest number of TB cases.

Here are seven simple facts you should know about TB in 2025:

The childhood TB vaccine still works

The small scar on your upper arm is from the BCG vaccine. It’s given to babies at birth to protect them from severe TB. While it may not stop all TB infections, it helps prevent the most serious cases.

Stay away from people who cough a lot

TB spreads through the air when an infected person coughs or sneezes, especially in crowded or poorly ventilated places. If someone has a persistent cough, it’s smart to keep your distance.

Face masks still help

Even after the pandemic, wearing a mask in crowded areas—like hospitals or public transport—can protect you from TB and other airborne diseases.

Keep your immune system strong

A healthy immune system can help fight TB. Eat nutritious foods, stay hydrated, sleep well, and manage stress. These simple habits make a difference.

Avoid crowded places if you’re unwell

TB spreads easily in busy places. If you’re sick or have a lingering cough, it’s best to stay home and avoid gatherings to protect yourself and others.

Cover your mouth when you cough

Don’t cough into your hands. Use a tissue or your elbow and wash your hands afterward. This simple act helps prevent the spread of TB and other germs.

Don’t ignore a long-lasting cough

If you’ve been coughing for more than two weeks, visit a health centre for a TB test. Early diagnosis can save your life and prevent the disease from spreading.

Why is this important?

TB isn’t just a distant problem—it’s affecting people in your community. The good news is that TB is preventable, treatable, and curable if caught early.

If you have a persistent cough, don’t ignore it—get tested and stay safe.
