Tuberculosis: What It Is and How to Prevent It
Tuberculosis (TB) is a highly contagious bacterial infection caused by Mycobacterium tuberculosis. It primarily affects the lungs but can spread to other parts of the body. TB is a major global health concern, but the good news is that it is preventable and treatable.
How TB Spreads
TB is an airborne disease, spreading when an infected person coughs, sneezes, or speaks. While not everyone exposed to TB bacteria becomes sick, those with weakened immune systems are at higher risk of developing active TB disease.
Signs and Symptoms
- ✅ Persistent cough (lasting more than three weeks)
- ✅ Coughing up blood or phlegm
- ✅ Night sweats
- ✅ Unexplained weight loss
- ✅ Fever and chills
- ✅ Fatigue
Prevention Strategies
Preventing TB requires a combination of public health measures and individual actions:
1. Get Tested If at Risk
People at high risk (e.g., healthcare workers, those in close contact with TB patients, or individuals with weakened immune systems) should undergo TB testing. Early detection prevents the disease from spreading.
2. Take Prescribed TB Medications
If diagnosed with latent TB (inactive but present in the body), completing prescribed antibiotics can prevent it from becoming active. For active TB, completing the full treatment is crucial to prevent resistance.
3. Maintain Proper Hygiene and Ventilation
Since TB spreads through the air, proper ventilation in living and working spaces is essential. Good respiratory hygiene, like covering your mouth when coughing or sneezing, can also reduce transmission.
4. Strengthen Your Immune System
A strong immune system can help prevent TB infection. A healthy diet, regular exercise, and adequate sleep all play a role in protecting against infections.
5. Get Vaccinated (for High-Risk Groups)
The Bacillus Calmette-Guérin (BCG) vaccine can offer protection, especially for children in countries where TB is common. However, it is not widely used in the U.S. due to its limited effectiveness in adults.
Final Thoughts
TB remains a serious global health challenge, but prevention starts with awareness, early detection, and responsible treatment. If you or someone you know is at risk, consult a healthcare provider about testing and prevention strategies.
