TB Statistics – Global, regional, high burden & MDR

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). By contrast 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.

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/

Global Total 1,100,000 390,000 13,000,000 9,600,000 7,239,269,000

The “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 statistics page.

TB statistics for “high burden” countries

Of all the countries that report their TB statistics to WHO, there are 22 countries that are sometimes referred to as the TB “high burden” countries, and they 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 2013.4“Global Tuberculosis Control 2015, WHO, Geneva, 2015 www.who.int/tb/publications/global_report/

TB statistics for MDR TB

Multi drug resistant TB (MDR TB) is the name given to TB when the bacteria that are causing it are resistant to at least isoniazid and rifampicin, the most effective TB drugs. In 2014 the World Health Organisation (WHO) estimated that there were globally 290,000 cases of MDR-TB among those cases of pulmonary TB that were reported to them.5“Global Tuberculosis Control 2015, WHO, Geneva, 2015 www.who.int/tb/publications/global_report/ It was also estimated that in total there were 650,000 cases of MDR TB among the worlds 12 million prevalent cases of TB.6“Global Tuberculosis Control 2015”, WHO, Geneva, 2015 www.who.int/tb/publications/global_report/

There are 27 “high burden” countries for MDR-TB. These are countries where there are at least 4,000 cases of MDR TB each year, and/or at least 10% of newly registered TB cases are of MDR TB.

The table below shows the estimated number of cases for each “high burden” country. It should however be noted, that these are only the estimates for the number of cases of MDR-TB amongst those cases of pulmonary TB notified to WHO. There will in addition have been many cases of MDR amongst those cases of TB which were either not detected and/or not notified.7“Global Tuberculosis Control 2015”, WHO, Geneva, 2015 www.who.int/tb/publications/global_report/
