TB Statistics – Global, regional & high burden

National TB statistics

With national TB statistics there will generally be two main types of TB statistics. There will be reports of actual cases, which is the minimum number of people affected, but these TB statistics are of limited use if many cases go unreported. There are also estimates, which are based on surveys, and they are often used to give the proportion of people living with TB. There will always be various assumptions made in compiling estimates, which is why they can sometimes provide very different figures from the TB statistics based on reported cases.

TB statistics and indeed the statistics for other diseases, will often refer to the incidence and prevalence of a disease. The TB incidence is the number of new cases of active TB disease in a population during a certain time period (usually a year). The TB cases by country page gives the estimated incidence of almost every country in the world. The TB prevalence is the number of people in the population who are living with active TB. Prevalence is usually, but not always given as a percentage of the population.1“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

Global TB statistics

In 2014 1.5 million people died of TB. Of these people 0.4 million people were HIV positive.

TB now annually causes more deaths worldwide than HIV.

In 2014 1.2 million people died of HIV and this includes the 0.4 million TB deaths among HIV positive people. People who have both TB and HIV when they die, are internationally classified as having died from HIV.

There were an estimated 9.6 million new cases of TB in 2014. There were an estimated 3.2 million cases and 480,000 TB deaths among women.

There were also an estimated 1.0 million cases of TB in children and 140,000 deaths.

In 2012 more than 10 million children were orphaned as a result of their parents death from TB.2“Annual meeting of the Childhood TB subgroup”, 11th November 2012 www.stoptb.org

There were also in 2014 an estimated 480,000 new cases of MDR-TB and an estimated 190,000 people died of MDR-TB.

When the number of deaths becomes as large as 1.5 million, it can be hard to really understand what it means. So to further develop your understanding of what it is like, please read about dying of TB.

Regional TB statistics

All countries are asked to report their TB figures to the World Health Organisation (WHO), who then use these notified figures to help produce estimated total TB statistics for each country, region and globally. Globally it is thought that fewer than two-thirds (63%) of TB cases are notified. The WHO figures for the estimated incidence, prevalence and number of deaths from TB in each WHO region are given below.3“Global Tuberculosis Control 2015, WHO, Geneva, 2015 www.who.int/tb/publications/global_report/

Estimated WHO Regional TB statistics for 2014
Region TB Mortality HIV positive TB Mortality Prevalence Incidence Population
Africa 450,000 310,000 3,200,000 2,700,000 963,361,000
Americas 17,000 6,000 350,000 280,000 981,613,000
Eastern Mediterranean 88,000 3,200 1,000,000 740,000 635,745,000
Europe 33,000 3,200 440,000 340,000 907,279,000
South-East Asia 460,000 62,000 5,400,000 4,000,000 1,906,087,000
Western Pacific 88,000 4,900 2,100,000 1,600,000 1,845,184,000
Global Total 1,100,000 390,000 13,000,000 9,600,000 7,239,269,000

The TB “mortality” figures exclude the deaths of people who had both TB and HIV infection at the time of their death, as these are internationally classified as HIV deaths, and are shown separately in the tables. More statistics about HIV and TB co-infection, can be found on the TB and HIV co-infection statistics page.

TB statistics for “high burden” countries

Of all the countries that report their TB statistics to WHO, there are 22 countries that have sometimes been referred to as the TB “high burden” countries. These countries have been prioritized at a global level since 2000. There are currently 22 of these countries and between them they accounted for 82% of all estimated cases of TB worldwide in 2014.4“Global Tuberculosis Control 2015, WHO, Geneva, 2015 www.who.int/tb/publications/global_report/

In addition to the main list of 22 high burden countries (HBCs) there is also a list of 41 TB/HIV HBCs and a list of 27 TB high MDR-TB burden countries. In 2015 the WHO decided to revise the lists and there is more about this on the TB high burden countries page.

There are more TB Statistics for India, TB Statistics for South Africa, TB Statistics for the United States and TB statistics for England.
