The TB statistics collected by the World Health Organisation (WHO) show that there were an estimated 10.0 million new cases of TB disease (also known as active TB) in 2018.
TB affects all countries and age groups but overall the best estimates are that in 2018 ninety per cent were adults (aged > or = 15), 57% were male 32% were adult women and 11% were children. 8.6% were people living with HIV. Two thirds were in eight countries India (27%), China (9%), Indonesia (8%), the Philippines (6%), Pakistan (6%), Nigeria (4%) Bangladesh (4%) and South Africa (3%).
Only 6% of cases were in the WHO European Region and the WHO Region of the Americas, each of which had 3% of cases.
In 2018 the TB statistics show that an estimated one million one hundred and twenty thousand children became ill with TB.
The severity of national epidemics varies widely. In 2018 there were under 10 new cases per 100,000 population in most high income countries. There were 150-400 in most of the 30 high TB burden countries, and above 500 in a few countries including Mozambique, the Philippines and South Africa.
Eight countries accounted for two thirds of the global total India (27%), China (9%), Indonesia (8%), the Philippines (6%), Pakistan (6%), Nigeria (4%), Bangladesh (4%) and South Africa (3%).
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 2018 the TB statistics show that there were a total of 1,491,000 TB related deaths, 1.24 million among HIV negative people and an additional 251,000 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 2018 including children with HIV associated TB. Of these children 173,000 were HIV negative, and 32,000 HIV positive.
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 cases of 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
Globally in 2018 there were an estimated 500,000 new cases of rifampicin (RR-TB) resistant TB. Drug resistant TB is now an increasing problem in the worldwide control of TB and in the attempts to end TB. The three countries with the largest share of the global burden in 2018 were India (27%), China (14%) and the Russian Federation (9%). Globally 3.4% of new TB cases and 18% of previously treated cases had MDR/RR-TB. The highest proportion (>50% in previously treated cases) were in the countries of the former Soviet Union.
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.Rates are per 100,000 population
|Country||Total TB Incidence||HIV prevalence in Incident TB (%)||Population (millions)
|Total for High Burden Countries||180||8.2||4,830|
|Central African Republic||540||26||5|
|Papua New Guinea||432||7.3||9|
