Throughout history, tuberculosis (TB) has been a formidable adversary, leaving a profound impact on societies. Known as “consumption” in the 18th and 19th centuries, it ravaged Victorian Britain, claiming countless lives and leaving a significant mark on the era’s literature and social fabric. Today, TB presents a renewed challenge as it resurfaces in modern urban settings like London. Recent data has unveiled a worrying trend: TB infection rates in London have surpassed those of Covid-19, prompting urgent questions about public health, socio-economic dynamics, and the complexities of disease eradication in contemporary urban environments.
The UK Health Security Agency has reported a concerning rise in TB cases in England, with a notable 11% increase in 2023, amounting to nearly 5,000 cases. Of these, a significant portion—1,659 cases—originated in London, marking a sharp rise from the previous year. Provisional figures for 2024 suggest a further 14% increase, highlighting the persistent threat that TB poses in the city. Despite England’s classification as a low-incidence country, with a national TB notification rate of 8.5 per 100,000 people, this statistic conceals significant regional disparities. Certain areas of London, such as Newham, exhibit alarmingly high rates, with notifications reaching 40.6 per 100,000 population. Other boroughs like Brent, Ealing, and Harrow also confront significant challenges in managing TB.
The historical context of TB in Britain is well-documented, with an estimated four million deaths recorded between 1851 and 1910. This era saw TB become a central theme in the works of authors such as Charles Dickens, who vividly depicted its societal impact. Despite advancements in medical treatment and preventive measures, TB remains a leading infectious killer worldwide, claiming an estimated 1.25 million lives in 2023 alone. The resurgence of TB in London starkly illustrates the disease’s enduring resilience and adaptability. While progress has been made, the goal of eradicating TB remains fraught with challenges. The World Health Organization’s target of a 90% reduction in TB cases by 2035, set in 2015, appears increasingly challenging to achieve.
Socio-economic factors play a critical role in the incidence of TB, particularly in urban environments like London. In England, the majority of TB cases occur among individuals born overseas, from countries such as India, Pakistan, Nigeria, and Romania. However, there has also been a notable rise in infections among the UK-born population. TB is closely linked to socio-economic deprivation, thriving in areas of poverty and among marginalised communities. In London, the disease disproportionately affects those experiencing homelessness, substance dependencies, and other forms of social exclusion. These “inclusion health groups” face multiple, overlapping risk factors that complicate efforts to control the disease’s spread. The dense population and diverse demographics of the urban landscape present unique public health challenges.
According to Dr. Esther Robinson, Head of the TB Unit at the UKHSA, awareness and timely intervention are crucial in combating TB. Despite being both curable and preventable, TB continues to pose a significant public health threat. Early detection and treatment hinge on recognising symptoms such as persistent cough, fever, and weight loss. Public health campaigns must therefore focus on educating at-risk communities and ensuring they have access to healthcare services. A collaborative approach across the health system is essential to refocus efforts on TB elimination, addressing the socio-economic determinants that perpetuate its spread.
The resurgence of TB in London serves as a poignant reminder of the ongoing battle against infectious diseases. In navigating the intricate landscape of modern public health, it is vital to draw lessons from the past while adapting strategies to contemporary challenges. Through concerted and collective action, there is hope that TB, much like its depiction in Dickensian narratives, can once again be relegated to the annals of history.
