How common is Tuberculosis in India ?

Tuberculosis is a disease of the third world countries. India has made rapid progress on all fronts but unfortunately the number of tuberculosis patients in India is still very high. Almost 20% patients of tuberculosis in the world are Indians. Tuberculosis is an infection caused by bacteria called Mycobacterium and malnourished people are more prone to the disease. Till the 70;s tuberculosis was the biggest killer in the country. Even now TB results in the death of many people in the remote areas of the country where the system of early diagnosis is not in place. The government has a big programme called DOTS for the eradication of TB in the country.

What is drug resistant TB ?

TB is treatable and curable; however, people with TB can die if they do not get proper treatment. Sometimes drug-resistant TB occurs when bacteria become resistant to the drugs used to treat TB. This means that the drug can no longer kill the TB bacteria.

Drug-resistant TB can occur when the drugs used to treat TB are misused or mismanaged. Examples of misuse or mismanagement include

  • People do not complete a full course of TB treatment
  • Health care providers prescribe the wrong treatment (the wrong dose or length of time)
  • Drugs for proper treatment are not available
  • Drugs are of poor quality

Drug-resistant TB is more common in people who

  • Do not take their TB drugs regularly
  • Do not take all of their TB drugs
  • Develop TB disease again, after being treated for TB disease in the past
  • Come from areas of the world where drug-resistant TB is common
  • Have spent time with someone known to have drug-resistant TB disease
