What is the prevalence of Tuberculosis?

Tuberculosis is a global health challenge caused by Mycobacterium tuberculosis, affecting an estimated 10.6 million people annually with new cases, making it a common infectious disease rather than a rare one. While global prevalence is high, the burden is unevenly distributed across geographic regions, age groups, and socioeconomic settings.

Is Tuberculosis considered a rare disease?

Unlike many conditions mapped on DiseaseMaps.org, Tuberculosis is not classified as a rare or ultra-rare disease. According to the World Health Organization (WHO), it remains one of the world’s deadliest infectious killers. While the DiseaseMaps.org community currently includes 3 members living with the condition, globally, millions are affected, highlighting that Tuberculosis is a major public health priority rather than a niche rare disorder.

What are the global incidence and prevalence statistics?

Estimating the exact number of people living with Tuberculosis is complex due to high rates of latent infection. Key epidemiological data points include:

• Annual Incidence: Approximately 10.6 million people developed Tuberculosis in 2022 (WHO Global TB Report).


• Mortality: Roughly 1.3 million people died from Tuberculosis in 2022.


• Latent Burden: It is estimated that approximately one-quarter of the world’s population is infected with latent Tuberculosis, meaning they are infected but not yet ill and cannot transmit the disease.

How do age and gender influence Tuberculosis?

Tuberculosis affects individuals across all age groups, though it is most frequently diagnosed in adults. In 2022, men accounted for 56.5% of cases, adult women for 32.5%, and children for 11%. The disease distribution is heavily influenced by geography, with the majority of cases occurring in the WHO South-East Asia, African, and Western Pacific regions. Challenges in accurate data collection persist, particularly in regions with limited healthcare infrastructure, leading to significant underreporting and underdiagnosis of Tuberculosis.

Next steps

• Consult an infectious disease specialist if you suspect exposure or exhibit persistent symptoms like chronic cough or night sweats.


• Visit the World Health Organization (WHO) TB department website for global screening guidelines.


• Connect with others who have navigated treatment journeys via the DiseaseMaps.org community platform.


• Ensure you complete the full course of prescribed antibiotics if diagnosed to prevent the development of drug-resistant strains.
