Tuberculosis (TB) cases in London have reached the highest level recorded in years, according to the latest data.
Experts warned that the world is “losing the battle” to eliminate the virus, as the capital experiences rates almost double those of any other region in England.
Figures released by the UK Health Security Agency (UKHSA) reveal that 471 tuberculosis (TB) infections were reported in the capital between April and June 2023.
London also has the highest TB rate in all of Western Europe and is the only Western European country to have rising cases of TB right now, according to University College Hospital (UCLH).
But why are rates so high in London and what symptoms should people look out for? Here’s what you need to know.
Why are TB cases rising in London?
According to a study from the British Medical Journal (BMJ), London’s rising rates reflect a worldwide increase in tuberculosis.
However, as also noted in the study, there are particularly high rates among ethnic minorities and those with existing health conditions, so it’s possible that London’s diverse population could account for the relatively higher rates.
The BMJ notes that the work has been carried out to combat this rise, but “more is needed”, specifically through “tuberculosis control and prevention strategies” and providing “information, diagnosis and treatment tailored to the specific needs of the capital and its at-risk groups”.
How do you catch TB?
Tuberculosis is a bacterial infection that is caught by inhaling tiny droplets from coughs or sneezes of an infected person.
It largely affects the lungs, but can affect any part of the body, such as the glands, bones, and nervous system.
Common symptoms include a long-lasting of cough of more than three weeks, tiredness, fever, and sweating (particularly at night).
What is the treatment for TB?
If not treated properly, TB can be fatal. However, there are treatment options available.
In most active, healthy people, the immune system will kill the bacteria before any symptoms appear.
However, sometimes your body will not be able to kill the bacteria, but only manages to prevent it spreading in the body. Having this bacteria remain in your system is known as latent TB.
Treatment is required for active TB, where the immune system cannot kill or contain the bacteria, resulting in the symptoms listed above.
Treatment involves a course of antibiotics, usually over the span of six months.
Can tuberculosis be cured?
If a full course of antibiotics is taken, TB can usually be cured.
If you are being treated for TB, it’s wise for those close to you to also see a medical professional and get tested, to ensure that they don’t run the risk of leaving a case untreated.
