BBC News reports that six weeks after the E.coli outbreak in south Wales, health experts have begun testing over 200 children after E.coli cases were discovered at a school not much far from the original outbreak.
The outbreak affected 171 people, most of them children, in more than 40 schools. The infection also led to the death of five-year-old Mason Jones.
At the moment, outbreak control team says the sources of the infection are unclear. Officials have said it is likely that the infection remains in the community due to the widespread nature of its original distribution.
The new infections has prompted the team to reiterate to parents the need to keep vigilant and let their doctor know if their child has bloody diarrhea.
A food hygiene leaflet will be sent to all schools in Wales.
