I was recently diagnosed with tuberculosis, which was quite the shock since I’d assumed it to be a disease left behind in Victorian slums – only briefly making a comeback to kill off heroines in old Westerns. But there I was being prescribed strong antibiotics by a very serious nurse, realising that despite my naivety, the disease has made a big comeback in London in the past 15 years.
A 2015 report from the London Assembly found that one third of London’s boroughs exceed the World Health Organisation's (WHO) ‘high incidence’ threshold of 40 cases per 100,000 people. The boroughs of Newham, Brent, Ealing and Hounslow have some of worst rates in the country, comparable with significantly less developed countries such as Rwanda, Algeria and Guatemala. It is no wonder that the capital has picked up the rather unsavoury title of ‘TB capital of Western Europe’.
Having TB means being infected by ‘Mycobacterium tuberculosis’, which manifests in one of two ways within a person. If ‘active’, the bacteria is damaging your body and you can infect other people. Symptoms include a loss of appetite, weight loss and a persistent cough that may bring up blood. If treatment cannot be accessed it can lead to death.
Luckily for me, and everyone forced to commute with me on the Victoria Line, my tuberculosis is ‘latent’. This means that I’m both symptomless and not infectious. If untreated, latent TB has around a one in ten chance of becoming active, but a three-month course in antibiotics takes this down to one in 100.
Anti-immigration groups like the now-obsolete BNP were quick to claim a connection between TB’s resurgence and London’s high immigrant population. But this doesn’t tell the whole story: although 74 per cent of cases in London do occur in people born abroad, it is highly unlikely they could have brought active TB into the UK. People applying for visas from countries with high incidence rates are required to get medically screened.
The disease instead ‘activates’ here, particularly in areas that are strongly linked with deprivation and the associated poor housing, poor nutrition and general ill health. Newham is in one of the poorest boroughs in London and comparable levels of poverty can be seen in the other ‘high incidence’ areas.
Health inequality plays a big part in TB getting a foothold in the city, with many affected having inadequate access to inadequate services. If it wasn’t already, this means limiting access to healthcare for migrants would be a terrible idea. The restrictions around healthcare imposed under the ‘hostile environment’will likely deter people from receiving treatment that they need. Untreated carriers of active TB spread the disease and drug-resistant strains are on the rise.
The WHO estimates that two billion people across the world are infected with tuberculosis. Although I’m soon to be TB-free, London is still very much under threat. A co-ordinated approach is needed; not just improving outreach programs among vulnerable demographics, but also tackling the socio-economic causes. This Victorian disease should be resigned to history and not allowed to become a feature of modern London.
