Pupils and teachers at a junior school are being screened for TB after four pupils tested positive for the disease.
A letter was sent to parents of pupils at Southfields Junior School, in Luton, Beds, offering the tests after a pupil displayed symptoms of tuberculosis.
Three of his classmates were confirmed to also be in the early stages of the disease, which the Health Protection Agency said is not contracted easily.
Luton has three times as many incidents of TB than the national average.
You know in what other respect Luton beats the national average by three to one? In the number of immigrants enriching it. In the 2001 census, 7.5% of respondents nationwide were born outside the UK. But in Luton, that figure was nearly 20%.
Of course, there could be some other explanation for these particular cases. But it has been clearly established that, to quote from a report (warning: pdf) from the charity TB Alert, "increases in TB rates are linked to immigration". If the Luton schoolchildren did not get TB as a result of immigration, plenty of other people did.
Just another one of the myriad ways in which immigration enriches Britain.
