Officials with Public Health England (PHE) reported on new data that shows the number of people in England diagnosed with tuberculosis (TB) is at its lowest level since 1990.
Following action by PHE, the NHS and others, there was a 38% drop in new diagnoses from the peak in 2011 to 2017 (from 8,280 to 5,102), with a 9% fall in diagnoses between 2016 and 2017 alone.
The incidence rate of TB in England is now 9.2 per 100,000 population – taking England to below the World Health Organisation definition of a low incidence country (10 per 100,000 population) for the first time.
Public Health England has played a key role in driving down the rates of TB in England, working with NHS England and other partner organisations to implement the ‘Collaborative Tuberculosis Strategy for England 2015 to 2020’. This includes raising awareness and tackling TB in underserved populations, implementing testing for latent TB in those arriving from countries with high rates of TB, and strengthening surveillance and monitoring.
Dr Sarah Anderson, Head of TB Strategy at Public Health England, said:
It is hugely encouraging to see a continued decline in TB in England which shows that the interventions we are putting in place are having an impact and will hopefully one day soon consign TB to the history books. While these new figures are positive, challenges still exist.
The proportion of people who experience a delay between symptom onset and diagnosis remains stubbornly high. We are working across England to ensure that patients are diagnosed and treated as soon as possible to minimise the chance of long-term ill health and onward transmission.
The risk factors for tuberculosis – a bacterial infection that primarily affects the lungs and causes persistent cough, fever and weight loss – include homelessness, poor quality housing, alcohol and substance misuse.
The new data indicates that nearly 13% of people with TB have a ‘social risk factor’ and that they are more likely to have drug resistant infections and are less likely to complete treatment, prolonging the infection and increasing the risk of onward infection.
