So far 75 people have been affected (primary cases): 67 in England, 3 in Wales and 5 in Scotland. Genetic analysis has shown that all these individuals have all been infected with the same E.coli strain. Most of these cases are adults but the total number of cases has an age range of between 2 to 90. Twenty-seven males and 48 (64%) females have been affected.

In addition, there have also been 10 secondary cases reported. These are people who have become unwell through contact with a primary case.

Further details are available on 82 of the total cases all of whom reported symptoms of diarrhoea. Bloody diarrhoea was reported by 58 people (71%) and 25 people have been hospitalised as a result of their illness. There have been no deaths or cases of haemolytic-uraemic syndrome which is a serious complication of an E. coli infection which can result in kidney failure.

At present there is no clear indication as to what is causing the outbreak.
