The global fight against tuberculosis, a disease that continues to claim more lives than any other infectious illness, receives renewed focus on March 24th, World TB Day. This year’s theme – “Yes! People can End TB: Led by countries. Powered by people” – isn’t simply aspirational; it’s a call to action rooted in the understanding that eliminating tuberculosis is achievable through concerted national efforts and community engagement. Even as significant progress has been made in reducing TB incidence globally, recent trends in some regions, including Ireland, demonstrate the need for sustained vigilance and innovative strategies to address this persistent public health challenge.
Tuberculosis, caused by the bacterium Mycobacterium tuberculosis, primarily affects the lungs but can spread to other parts of the body. The disease is preventable and curable with appropriate treatment, yet millions still fall ill each year. The World Health Organization (WHO) estimates that 10.6 million people fell ill with TB globally in 2022, and 1.3 million people died from it, including 167,000 people living with HIV. Addressing the social and economic factors that contribute to TB transmission is crucial, as the disease disproportionately affects vulnerable and underserved populations.
A Recent Rise in Cases: The Situation in Ireland
While Ireland has historically seen a decline in TB rates, that trend has stalled and even reversed in recent years. Data from the Health Protection Surveillance Centre (HPSC) reveals a concerning 32% increase in TB rates per 100,000 population between 2023 (4.3) and 2024 (5.6). In 2025, rates stabilized at 5.5, with 285 people notified with TB across the country, according to the HPSC. The latest data on Tuberculosis in Ireland provides a detailed overview of these trends.
This increase is particularly noteworthy given Ireland’s status as a low-incidence country – defined as fewer than 10 cases per 100,000 population. The WHO’s End TB Strategy sets an ambitious target of an 80% reduction in TB cases between 2015 and 2030. For Ireland, achieving this goal would have meant diagnosing approximately 123 cases in 2025, significantly less than the 285 actually reported. This gap underscores the challenges in maintaining progress and the need for intensified efforts.
A New National Strategy for TB Control
Recognizing the need for a more coordinated and comprehensive approach, the Health Service Executive (HSE) published “Striving to End Tuberculosis: A Strategy for Ireland 2024-2030” last year. This marks Ireland’s first dedicated National TB Strategy, outlining a vision for collaborative, multisectoral TB control. The strategy emphasizes the importance of addressing health inequities, acknowledging that TB is increasingly concentrated among vulnerable populations. Removing barriers to accessing TB care is a central tenet, with the understanding that protecting the health of individuals with TB too safeguards the wider community – a principle encapsulated by the phrase “No One is Safe Until Everyone Is Safe.”
Understanding Tuberculosis: Symptoms and Transmission
Tuberculosis is spread through the air when a person with active TB disease coughs, speaks, sings, or sneezes. While TB typically affects the lungs, it can also impact other parts of the body, including the glands, bones, and, rarely, the brain. Historically, TB was far more prevalent in Ireland, with nearly 7,000 cases annually in the early 1950s. Detailed epidemiological reports on TB in Ireland are available on the HPSC website. These reports provide valuable insights into the disease’s patterns and trends.
Doctors in Ireland are legally obligated to notify the local Departments of Public Health in the HSE of each diagnosed case of TB, as outlined by the HPSC’s notification guidelines. This reporting system is crucial for tracking the disease, identifying outbreaks, and implementing effective control measures.
Recognizing the Signs: Symptoms of TB
Early detection is key to successful TB treatment. Individuals should be aware of the following potential symptoms:
- Fever and night sweats
- A persistent cough lasting more than three weeks
- Unexplained weight loss
- Blood in sputum (phlegm)
Anyone experiencing these symptoms should consult their family doctor for evaluation. Open communication with healthcare providers about potential TB exposure is also vital.

The success of Ireland’s new national strategy, and the global effort to end TB, will depend on sustained investment in research, improved access to diagnosis and treatment, and a commitment to addressing the underlying social determinants of health. The next major update on the implementation of the HSE’s TB strategy is expected in the fourth quarter of 2026, providing a crucial opportunity to assess progress and refine approaches.
