Tuberculosis, or TB, is an infection caused by bacteria that usually affects the lungs. It spreads when someone with active TB coughs, sneezes, or talks, releasing tiny droplets into the air. TB is a serious illness, but it can be prevented and treated successfully. Knowing how TB spreads and the steps you can take to prevent it is important to protect yourself, your family, and your community.

Key Takeaways
- TB is most contagious before treatment starts, so early detection is vital.
- Directly Observed Treatment (DOT) ensures patients take their TB medicine correctly and completely.
- Protecting high-risk groups and maintaining good hygiene can prevent TB spread.
- BCG vaccination and TB preventive therapy are important preventive strategies.
- Avoiding overcrowding, improving ventilation, and safe food practices reduce TB risk.
How TB is Prevented
Early Detection and Treatment
People with TB are most infectious before starting treatment. Healthcare providers focus on early detection and immediate initiation of appropriate treatment. This usually involves:
- Providing protective equipment (PPE) to patients who are sputum-positive to reduce spread.
- Giving TB medicines under Directly Observed Treatment (DOT), where healthcare workers monitor medication intake to ensure it is taken correctly.
- Following up regularly to make sure treatment is completed and the patient is cured.
Contact Tracing
Healthcare teams trace and screen people who have been in close contact with a TB patient. This is especially important for:
- Children under 5 years old
- People living with HIV
- Patients with drug-resistant TB (MDR TB)
- Patients with a positive TB test or chest x-ray showing lung damage
Routine screening of healthcare workers is also carried out to detect latent or active TB early.
Vaccination and Preventive Treatment
- BCG vaccination at birth helps prevent severe TB in children.
- TB Preventive Treatment (TPT) is given to people at higher risk, such as those living with HIV or children exposed to TB.
General Hygiene and Healthy Practices
- Avoid overcrowded spaces where TB bacteria can spread easily.
- Cover your mouth and nose when coughing or sneezing, dispose of sputum safely, and wash hands with soap.
- Ensure good ventilation at home and in public transport by opening windows and doors.
- Do not drink unboiled milk, as TB can spread through infected milk.
- Maintain good nutrition to support a strong immune system.
FAQ: Common Questions About TB Prevention
1. How can I know if I have been exposed to TB?
If you have been in close contact with someone diagnosed with TB, a healthcare provider may screen you with a skin test or blood test.
2. Can TB be prevented in children?
Yes, children receive the BCG vaccine at birth, which protects against severe TB forms.
3. What is Directly Observed Treatment (DOT)?
DOT means a healthcare worker watches the patient take their TB medicine to ensure proper use and complete cure.
4. Who should receive TB preventive treatment?
People at higher risk, such as children under 5, people living with HIV, and those exposed to TB, may receive preventive medicines.
5. How important is ventilation in TB prevention?
Very important. Good airflow in homes and transport helps reduce the concentration of TB bacteria in the air.
6. Can TB spread through food or drinks?
TB can spread through unboiled milk from infected cows, so always ensure milk is boiled before drinking.
7. How do I protect myself if I live with a TB patient?
Encourage your household to follow cough hygiene, ensure proper ventilation, avoid overcrowding, and seek advice from a healthcare provider, who may also recommend screening or preventive treatment.
