Tuberculosis in India: A Persistent Public Health Challenge


Introduction

Tuberculosis (TB) is a contagious bacterial infection caused by Mycobacterium tuberculosis. Despite being preventable and curable, TB remains a major public health concern in India, accounting for the highest burden of cases globally. The Indian government, through initiatives like the National Tuberculosis Elimination Program (NTEP), is actively working to control and eliminate the disease.

Origins and Spread
TB has existed for thousands of years, with evidence found in Egyptian mummies. It spreads through the air when an infected person coughs, sneezes, or speaks. Overcrowding, poor ventilation, and malnutrition contribute to its rapid transmission, making densely populated regions in India particularly vulnerable.

Symptoms
Common symptoms of TB include:

  • Persistent cough lasting more than two weeks

  • Chest pain

  • Coughing up blood

  • Fever and night sweats

  • Unexplained weight loss

  • Fatigue

Death Rate and Impact
TB is one of the deadliest infectious diseases in India. According to the World Health Organization (WHO), India accounted for approximately 28% of global TB cases in recent years. Despite advances in treatment, drug-resistant TB strains have emerged, posing new challenges to disease management. However, early diagnosis and proper treatment significantly reduce mortality rates.

Cure and Treatment
TB is treatable with a combination of antibiotics known as the Directly Observed Treatment Short-course (DOTS) regimen. Treatment lasts for six months or more, depending on the type and severity of TB. For drug-resistant TB, more potent medications and a longer treatment duration are required. The government provides free diagnosis and treatment at public health centers.

Prevention Strategies
Preventing TB requires a multi-faceted approach:

  • Vaccination: The Bacillus Calmette-Guérin (BCG) vaccine is administered to newborns to provide partial protection.

  • Early Diagnosis & Treatment: Prompt identification and complete treatment of TB cases reduce transmission.

  • Improved Living Conditions: Reducing overcrowding, improving ventilation, and ensuring better nutrition can help lower TB risk.

  • Public Awareness: Educational campaigns help reduce stigma and encourage people to seek timely medical help.

Conclusion
Tuberculosis continues to be a major health challenge in India, but with government initiatives, improved healthcare infrastructure, and increased public awareness, progress is being m

ade toward its elimination. Early detection, adherence to treatment, and preventive measures remain key to controlling TB in the country.
