I don’t know what it is with baby nurseries and what I guess Americans would call daycare for the older kids in the U.K., but there are way too many outbreaks of E. coli O157.

The Hounslow Chronicle reports that as many as 25 pupils at Feltham Hill Infant & Nursery School are believed to have been infected by the E. coli bug.

A spokeswoman for the Health Protection Agency today said there were now five confirmed cases of the O157 strain, with another seven presumed positive and 13 ‘symptomatic’ cases, which are still being investigated. She could not confirm whether everyone who had been infected was a pupil at the school in Bedfont Road.

Today, it was reported that a second nursery in Feltham has closed following a suspected outbreak of E. coli.

Once Upon a Time Nursery, in Ashford Road, closed on Friday after 11 children suffered diarrhoea and vomiting, which are symptoms of the infection.

A spokeswoman for the HPA said it was too early to say whether the infection is related to the E. coli outbreak or is an outbreak of norovirus, which has similar symptoms and is common at this time of the year.
