Current screening for TB in immigrants arriving in the UK is missing the majority of cases, say researchers. 70% to be precise.
Using new blood tests for checks would be better than chest X-rays, which detect only active infections, says an Imperial College London team which analysed more than 1,000 immigrants. Blood tests could prevent substantial numbers of cases, they write in The Lancet Infectious Diseases. The government said the research backed new guidance from health watchdog NICE. Tuberculosis is caused by a bacterial infection, which attacks the lungs. It has risen dramatically in the UK over the past decade, partly because of an increase in cases among people who move to the country from overseas.
Or to put it more precisely, immigration from Africa and parts of Sub-Asia. There is a major health problem looming here and the primary cause is the massive immigration we have experienced combined with inaccurate testing. TB was once considered beaten but it is back.
