How to Prevent TB (Tuberculosis)?

Preventing Tuberculosis requires awareness, early testing, and healthy lifestyle practices. TB spreads through the air when an infected person coughs or sneezes. Following preventive steps can significantly reduce the risk of infection.

Get the BCG Vaccination: The BCG vaccine helps protect children against severe forms of tuberculosis and is widely used in many countries.
Seek Early Diagnosis and Treatment: If TB symptoms appear, consult a doctor immediately. Early diagnosis and proper treatment help stop the spread of the disease.
Cover Mouth While Coughing or Sneezing: Use a tissue, handkerchief, or mask to prevent TB bacteria from spreading through the air.
Ensure Proper Ventilation: TB bacteria spread more easily in closed spaces. Fresh air and sunlight help reduce the risk of transmission.
Maintain Strong Immunity: Eat a balanced diet, exercise regularly, and get enough rest to keep the immune system strong.
Avoid Close Contact with Untreated TB Patients: People with active TB should follow medical advice and complete their treatment to prevent spreading the infection.

Health awareness programs during World Tuberculosis Day encourage communities to adopt these preventive measures and reduce TB cases worldwide.
