Additional highlights from the report Disease burden and 2015 targets assessment
The quantity and quality of data available to estimate TB disease burden continue to improve. These include direct measurements of mortality in 129 countries and final results from 18 national TB prevalence surveys completed since 2009, six of them in the past year (Ghana, Indonesia,Malawi, Sudan, Zambia and Zimbabwe).
Revised estimates for Indonesia (1 million new cases per year, double the previous estimate) explain the upward
revision to WHO’s global estimates of incident cases compared with those published in 2014. Importantly, however, revisions also affect estimates for previous years and thetrend in TB incidence globally as well as in Indonesia is still
downward since around 2000.
Of the 9.6 million new TB cases in 2014, 58% were in the
South-East Asia and Western Pacific regions. The African Region had 28% of the world’s cases in 2014, but the most severe burden relative to population: 281 cases for every 100 000 people, more than double the
global average of 133. India, Indonesia and China had the largest number of cases: 23%, 10% and 10% of the global total, respectively.
Globally, TB prevalence in 2015 was 42% lower than in1990. The target of halving the rate compared with 1990was achieved in three WHO regions – the Region of theAmericas, the South-East Asia Region and the Western Pacific Region – and in nine high-burden countries (Brazil,Cambodia, China, Ethiopia, India, Myanmar, the Philip pines, Uganda and Viet Nam).
The target of halving the TB mortality rate by 2015 compared with 1990 was met in four WHO regions – the Region of the Americas, the Eastern Mediterranean Region, the South-East Asia Region and the Western Pacific Region – and in 11 high-burden countries (Brazil, Cambodia, China, Ethiopia, India, Myanmar, Pakistan, the Philippines, Uganda, VietNam and Zimbabwe).
All three of the 2015 targets (for incidence, prevalence and mortality) were met in nine high-burden countries Brazil, Cambodia, China, Ethiopia, India, Myanmar, the Philippines, Uganda and Viet Nam.
TB case notifications and treatment outcomes
In the 20 years since WHO established a global report ing system in 1995, it has received reports of 78 million TB
cases, 66 million of which were treated successfully. In 2014, that system measured a marked increase in global TB notifications for the first time since 2007. The annual total of new TB cases, which had been about 5.7 million until 2013, rose to slightly more than 6 million in 2014 (an increase of 6%). This was mostly due to a 29% increase in notifications in India, which followed the introduction of apolicy of mandatory notification in May 2012, creation of a national web-based reporting system in June 2012 and
