World TB Day: Combating Tuberculosis Together

Posted by: , Posted on: - Categories: WHO

March 24th marks World TB Day, an important moment to recognise the global effort required to eliminate tuberculosis (TB), a disease that, despite being preventable and curable, continues to be a global health threat. TB does not discriminate, affecting individuals across the world, including the UK, where it remains a significant public health issue.

TB is caused by the bacterium Mycobacterium tuberculosis and primarily affects the lungs, although it can impact other parts of the body. As we commemorate World TB Day, it's vital to remember that TB is not just a problem for the developing world but also presents challenges in developed countries, including the United Kingdom. See Tuberculosis in England, 2023 report (data up to end of 2022).

Research: The Medicines and Healthcare products Regulatory Agency (MHRA) plays a crucial role in the battle against TB through its research efforts. The agency's research focuses on understanding the mechanisms of TB (interaction with the host), the efficacy of vaccines, and the disease's pathogenesis (TB development/progression and immune responses), vaccine effectiveness in the scenarios of co-infection like TB and malaria. By developing sophisticated models, MHRA aims to unravel the complexities of TB spread, including its progression to the brain, which is critical for developing effective interventions.

Diagnostics: On the diagnostics front, the MHRA has made significant contributions to enhancing TB detection. Our agency has produced the First WHO international standard for Mycobacterium tuberculosis (H37Rv) DNA for Nucleic Acid technology-based assays and techniques for identifying Mycobacterium tuberculosis in patients. This standard ensures consistent and reliable results in TB diagnosis worldwide, which are crucial for early detection, treatment, and control of the disease. Discover more about these diagnostic tools.

Reference Reagents: Furthermore, the MHRA has been instrumental in TB research through the provision and distribution of the first WHO reference reagents for the BCG vaccine. These reagents are vital for vaccine evaluation, offering benchmarks for in vivo and in vitro assays crucial for new TB vaccine developments. See more information on these reagents.

As we mark World TB Day, let's recognise the significant efforts of organisations like the MHRA and the global health community in the fight against TB. However, the battle is far from over. It requires ongoing research, funding, and public health strategies to eliminate this disease once and for all. We all have a part to play in this fight, whether by staying informed, supporting TB research and initiatives, or advocating for better healthcare policies and practices.

Together, we can make TB history. Let's use World TB Day as a reminder of the work still needed and the hope that, with continued effort and collaboration, a TB-free world is within our reach.
