TB Statistics for India – National & state statistics

National TB statistics for India

India is the country with the highest burden of TB. The World Health Organisation (WHO) statistics for 2015 give an estimated incidence figure of 2.2 million cases of TB for India out of a global incidence of 9.6 million. The TB incidence for India is the number of new cases of active TB disease in India during a certain time period (usually a year).

The estimated TB prevalence figure for 2015 is given as 2.5 million.1“Global Tuberculosis Control 2015, WHO, Geneva, 2015 www.who.int/tb/publications/global_report/ The TB prevalence is the number of people in India who are living with active TB. Prevalence is usually, but not always given as a percentage of the population.2“Basic Statistics: About Incidence, Prevalence, Morbidity, and Mortality – Statistics Teaching Tools”, Department of Health, New York State www.health.ny.gov/diseases/chronic/basicstat.htm

It is estimated that about 40% of the Indian population is infected with TB bacteria, the vast majority of whom have latent rather than active TB.

Most of the national TB statistics for India are collected by the government Revised National Tuberculosis Control Programme (RNTCP) which was started in 1997, and which was then expanded across the country.

2010 1,192 7,550,522 939,062 128 n/a
2011 1,210 7,875,158 953,032 125 n/a

2015 1,285 9,132,306 902,732 111 184,802

The rate is the number per 100,000 population.

Sputum smear microscopy is the most common TB test, and the majority of people with TB are sputum smear positive. But some people who have TB, particularly people with both HIV and TB may be sputum smear negative.

Patients who experience only a short improvement whilst on drug treatment, or who never respond to treatment at all, are said to have failed their TB treatment. Patients are usually referred to as having defaulted on their treatment, and need retreatment, if they stopped taking their first course of drug treatment before they had finished the course.

Treatment success for New Smear Positive patients is defined as the patient being cured and their treatment has been completed. Treatment for new smear negative patients is that the patients treatment has been completed.

See the page on TB treatment for how drugs are used to treat TB.

TB treatment success among smear positive retreatment cases in India

2010 Not known 75% 68% 57% 71% 14%
2011 Not known 75% 68% 55% 71% 14%
2012 Not known 74% 66% 54% 70% 14%
2013 Not known 75% 66% 57% 71% 13%
2014 178,166 74% 66% 58% 70% 8%

TB retreatment is when patients need TB treatment again after they have ended their first course of drug treatment. People who need retreatment may be classified according to whether they relapsed, failed or defaulted on their original treatment.

In any retreatment situation it is possible that the person has got drug resistant TB. This is particularly likely to be the case if the person has never responded to and has failed their initial drug treatment. In this case they need drug susceptibility testing for drug resistance and they may need specific TB treatment for drug resistant TB.

The statistics given above are the figures for retreatment among smear positive patients. They do not include the retreatment outcomes for smear negative patients, who are subsequently found to have TB. Many of the smear negative patients will have both HIV and TB.

India state TB statistics

The main TB statistics for each state in India also come from the government Revised National Tuberculosis Control Programme (RNTCP).
