🌍 World TB Day – March 24
Tuberculosis (TB) may feel like a disease of the past — but its history tells a powerful story that still matters today.
During times of war, including World War I and II, TB spread rapidly. Crowded living conditions, poor nutrition, and limited access to healthcare created the perfect environment for infection. At one point, TB was one of the leading causes of death worldwide, often called “consumption” because of how it slowly weakened the body.
While we’ve made incredible progress, TB has never fully disappeared.
🫁 What is TB?
TB is a bacterial infection that usually affects the lungs and spreads through the air when an infected person coughs or speaks.
👥 Who can get TB?
Anyone can get TB — but risk increases with close contact, weakened immune systems, and shared living environments.
🏥 Why are healthcare workers screened?
Healthcare workers are routinely screened for TB because:
• They are at higher risk of exposure
• Early detection protects vulnerable patients
• It helps prevent outbreaks in healthcare settings
Screening is not just about the individual — it’s about protecting entire communities.
🧪 Prevention & Testing
• TB is preventable and treatable
• Testing includes skin tests, blood tests, and chest X-rays
• Early treatment stops the spread
💙 Why this matters today
TB is still considered a global health concern, affecting millions each year. Awareness, early detection, and reducing stigma are key to ending it.
