TB statistics summary
The global TB statistics are that there were an estimated 10.0 million new cases of TB disease (also known as active TB) in 2019. This is equivalent to 130 cases per 100,000 population.
TB affects all countries and age groups. Overall the best estimates are that in 2019 fifty six per cent were adult males. Thirty two per cent were adult women. Twelve per cent were children.
The 30 high TB burden countries accounted for 86% of all estimated incident cases worldwide.
Two thirds were in eight countries:
- India (26%),
- Indonesia (8.5%),
- China (8.4%),
- the Philippines (6%),
- Pakistan (5.7%),
- Nigeria (4.4%),
- Bangladesh (3.6%),
- South Africa (3.6%).
The severity of national TB epidemics, in terms of the annual number of incident TB cases, relative to population size (the incidence rate), varied widely among countries in 2019.
In 2019 54 countries had a low incidence of TB (< 10 cases per 100,000 population per year). These countries were mostly in the WHO region of the Americas and the European region plus a few countries in the Eastern Mediterranean and Western Pacific regions. For a number of these countries, including the United States, their target is the elimination of TB. There is more about TB in the United States.
There were 150-400 cases per 100,000 population in most of the 30 high TB burden countries, and more than 500 cases in the Central African Republic, the Democratic People's Republic of Korea, Lesotho, the Philippines and South Africa. Among the 30 high TB burden countries there were three with markedly lower incident rates per capita. These were Brazil, China ands the Russian Federation. These had best estimates of 46, 58 and 50 respectively.
In 2019 the TB statistics show that an estimated one million one hundred and ninety thousand children became ill with TB.
TB related deaths
TB is one of the top ten leading causes of death worldwide and the leading cause from a single infectious agent, ranking above HIV/AIDS.
In 2019 the TB statistics show that there were a total of 1,418,000 TB related deaths, 1.21 million among HIV negative people and an additional 208,000 among HIV positive people. People who have both TB and HIV when they die, are internationally classified as having died from HIV.
An estimated 205,000 children died of TB in 2019 including children with HIV associated TB. Of these children 194,000 were HIV negative, and 36,000 HIV positive.
Globally in 2019 16% of people who died were children aged <15 years. The higher share for children compared with their estimated share of cases (12%) suggests poorer acess to diagnosis and treatment.
There is more about deaths from TB in different countries.
World Health Organisation (WHO) TB statistics
All countries are asked to report their TB figures to the WHO. The people with TB page gives the reported (notified) figures for almost every country in the world.
WHO uses the reported figures to produce estimated TB incidence statistics for each country.
What does TB incidence mean?
TB incidence means the number of people who are estimated to have developed TB in a given period of time, which is normally a year. 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. It is estimated figures from WHO that are given on this page.
What does TB prevalence mean?
TB prevalence refers to the number of people with TB that are present in a particular population at a given time. Prevalence includes newly diagnosed people, plus people who were diagnosed in the past, and people who haven't even been diagnosed. 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. The best estimate of prevalence comes from surveys but because of the cost these are only produced for a limited number of countries.
TB statistics for drug resistant TB
The highest proportions of new and previously treated patients are in several countries of the former Soviet Union (above 25% in new cases and above 50% in previously treated cases).
The three countries with the largest share of the global burden in 2019 were:
- India (27%),
- China (14%)
- the Russian Federation (8%).
Bovine TB statistics
It is estimated that in some developing countries up to ten percent of human tuberculosis is due to bovine TB.

TB incidence for “high burden” countries
Of all the countries that report their TB statistics to WHO, there are a group of countries that are referred to as the TB “high burden” countries. These countries have been prioritized at a global level since 2000. In 2015 it was decided by WHO that the group would be revised and there is more about this on the TB high burden countries page.
The following is the estimated burden of TB for each of the 30 countries in the main high TB burden list.
|Country||Total TB Incidence (thousands)||Population (thousands)
|Central African Republic||26||4,750|
|Papua New Guinea||38||8,780|
|Total for High Burden Countries||8,610||4,880,000|
