The survey was conducted from 2019 to 2021 to know the actual disease burden of TB at the national level. The survey estimated the prevalence of microbiologically confirmed pulmonary TB among persons aged 15 years and above in India at the national level, and for 20 individual states.

The survey was conducted after a gap of 60 years. The last survey at the national level was conducted in 1955-58.

"Prevalence of microbiologically confirmed pulmonary tuberculosis in 15+ population in India is 316 per 100,000 population, while the prevalence of all forms of tuberculosis among all age groups in India is 312 per 100,000 population," revealed the survey.

Zoonotic TB Survivor Resolves to Make Her Community TB-free: World Tuberculosis Day
At the first-ever WHO global ministerial conference on ending TB in the Sustainable Development Era: A Multisectoral Response, Timpiyian Leseni tells us her story of how she managed to survive the deadly zoonotic extra-pulmonary TB (EPTB).

The highest prevalence for all forms of TB was 747 per lakh (510-984) in Delhi, and the lowest was 137 (76-198) in Gujarat.

According to the survey, the prevalence to notification ratio of adult pulmonary tuberculosis in India is 2.84, while prevalence of TB infection among population aged 15 and above is 31.7 per cent.

World Tuberculosis (TB) Day is observed every year on 24th March to create awareness on tuberculosis.

The higher prevalence of pulmonary TB was observed in older age groups, males, malnourished, smokers, alcoholics and known diabetics.

The survey revealed that the majority (64 per cent) of symptomatic population did not seek healthcare services. The reasons were ignoring the symptoms (68 per cent), not recognising the symptoms as TB (18 per cent), self-treatment (12 per cent) and couldn't afford to seek care (2 per cent).

The Lungs
The lungs are our organs of respiration. It is within these, that exchange of gases takes place.

Among the 36 per cent of survey participants who sought care for their symptoms, there was equal preference for government and private facilities.

The survey showed that among the diagnosed TB cases, 12 pe cent were already on treatment, while 23.3 per cent had a history of TB treatment. Hence, the close follow-up of patients completing treatment for early detection of recurrent TB and planning of intervention for preventing recurrence of TB is needed, the survey suggested.

"We should prioritise the interventions in high-prevalence states with focus on screening of elderly, malnourished and diabetic, and implement strategies to reduce the prevalence to notification gap," the survey said.
