It is estimated that a third of the global population is infected with latent TB — and one in ten of these people will go on to develop the disease.
Annually, over 10 million people develop TB, leading to nearly 2 million deaths — deaths that are avoidable through early diagnosis and treatment.
The missing 4 million
Of the 10.4 million people who fell ill with TB in 2015, 4.3 million did not get the care they needed. These ‘missing’ four million make up the majority of the 1.8 million people who died from TB in 2015. A quarter of TB deaths were among people with both TB and HIV.
High burden countries
Though TB is a global problem, the majority of people who fall ill with TB (60%) live in one six of countries: China, India, Indonesia, Nigeria, Pakistan, South Africa.
Of the 480 000 people that fell ill with multidrug-resistant TB (MDR-TB), 45% of them lived in just three countries: India, China and the Russian Federation.
Global TB targets
The Sustainable Development Goals (SDGs) for 2030, which were adopted by the United Nations in 2015, include a target to end the TB epidemic by 2030.
The WHO End TB Strategy, approved by the World Health Assembly in 2014, calls for a 90% reduction in TB deaths and an 80% reduction in the TB incidence rate by 2030, compared with 2015.
In order to meet these targets, global rates of decline in TB incidence need to accelerate from annually to 4–5% by 2020.
