Over 22 crore people screened for TB in 2021 across the country for early detection and treatment of TB
The WHO released the Global TB Report 2022 on October 27, 2022. The Report notes the impact of the COVID-19 pandemic on the diagnosis, treatment and burden of disease for TB all over the world. The Ministry of Health and Family Welfare has taken note of the WHO Global TB Report 2022, released on October 27, 2022, and has clarified that India has, in fact, performed far better on major metrics as compared to other countries over time. Indiaโs TB incidence for the year 2021 is 210 per 100,000 population โ compared to the baseline year of 2015 (incidence was 256 per lakh of population in India); there has been an 18% decline which is 7 percentage points better than the global average of 11%. These figures also place India at the 36thย position in terms of incidence rates (from largest to smallest incidence numbers).
While the COVID-19 pandemic impacted TB Programmes across the world, India was able to successfully offset the disruptions caused, through the introduction of critical interventions in 2020 and 2021 โ this led to the National TB Elimination Programme notifying over 21.4 lakh TB cases โ 18% higher than 2020. This success can be attributed to an array of forward-looking measures implemented by the Programme through the years, such as the mandatory notification policy to ensure all cases are reported to the government.
Further, intensified door-to-door Active Case Finding drives to screen patients and ensure no household is missed, has been a pillar of the Programme. In 2021, over 22 crore people were screened for TB. The aim has been to find and detect more cases to arrest onwards transmission of the disease in the community which has contributed to the decline in incidence. For this purpose, India has also scaled up diagnostic capability to strengthen detection efforts. Indigenously developed molecular diagnostics have helped expand the reach of diagnosis to every part of the country today. India has over 4,760 molecular diagnostic machines across the country, reaching every district.
Against this backdrop, and prior to the publication of the Global Report, the Ministry of Health and Family Welfare had communicated to WHO that the Ministry has already initiated domestic studies to arrive at a more accurate estimate of incidence and mortality rates in a systematic manner and Indiaโs data will be provided after conclusion of studies in early part of 2023. The WHO has also acknowledged the Health Ministryโs position on this and noted in the Report that โestimates of TB incidence and mortality in India for 2000โ2021 are interim and subject to finalization, in consultation with Indiaโs Ministry of Health & Family Welfareโ.
The results of the Health Ministryโs study, initiated by the Central TB Division (CTD), will be available in approximately six monthsโ time and shared further with WHO. These steps are in line with India conducting its own National Prevalence Survey to assess the true TB burden in the country โ the worldโs largest such survey ever conducted. The WHO Report notes that India is the only country to have completed such a survey in 2021, a year which saw โconsiderable recovery in Indiaโ.
The WHO Report also notes the crucial role of nutrition and under-nutrition as a contributory factor to the development of active TB disease. In this respect, the TB Programmeโs nutrition support scheme โย Ni-kshay Poshan Yojanaย โ has proved critical for the vulnerable. During 2020 and 2021, India made cash transfers of 89 million dollars (INR 670 crores) to TB patients through a Direct Benefit Transfer programme. Moreover, in September 2022, the Honourable President of India has launched a first-of-its-kind initiative, Pradhan Mantri TB Mukt Bharat Abhiyan to provide additional nutritional support to those on TB treatment, through contributions from community including individuals and organizations. Till date, 40,492 donors have come forward to support over 10,45,269 patients across the Country.
More positively, TB preventive treatment for people living with HIV has far surpassed the global target of 6 million in the period 2018-2022, reaching more than 10 million in only 4 years. Seven countries โ India, Nigeria, South Africa, Uganda, the United Republic of Tanzania, Zambia and Zimbabwe โ collectively accounted for 82% of those who started on preventive treatment in 2021.
Seven high TB burden countries in the region – Ethiopia, Kenya, Lesotho, Namibia, South Africa, the United Republic of Tanzania and Zambia- have reached or surpassed the 2020 milestone of a 20% reduction in the TB incidence rate compared with 2015.
Countries are also increasing the uptake of new tools and guidance recommended by WHO, resulting in early access to TB prevention and care and better outcomes. The proportion of people diagnosed with TB who were initially tested with a rapid diagnostic increased from 33% in 2020 to 38% in 2021. At least 109 countries were using all-oral longer regimens (up from 92 in 2020) for the treatment of MDR/RR-TB, and 92 were using shorter regimens (up from 65 in 2020).
