WHO Reports Record 8.2 Million Global TB Cases, UK Sees Sharp Increase in 2023

The World Health Organization has reported a significant surge in tuberculosis (TB) cases worldwide, with a record 8.2 million cases in 2023. The UK, too, has seen an unsettling rise in infections, reversing years of progress in TB prevention. As of July 2023, cases in England alone increased by 7%, reaching 2,630, up from 2,434 in 2019, the last pre-pandemic figure, according to the UK Health Security Agency (UKHSA).

If current trends continue, the UK could surpass last year’s total of over 4,800 cases—a record high since 2017. This resurgence follows a steady decline in cases over the past decade, dropping from a peak of 8,000 cases in 2011. The unexpected spike in 2023 prompted health officials to issue public warnings, encouraging individuals to consult a medical professional if they experience persistent cold or flu-like symptoms.

Although TB’s global fatality rate remains around one in six, the UK reports fewer deaths thanks to the availability of antibiotic treatments. Nonetheless, UK health authorities are concerned about the potential for ongoing spread and are investigating possible causes behind the recent uptick. Early symptom recognition and timely treatment remain key to controlling TB, especially given its ability to mimic common respiratory infections in early stages.

Health officials are urging the public to stay vigilant and to seek medical evaluation for any prolonged cough or respiratory discomfort.
