Escherichia coli (E. coli) O157
Symptoms of E. coli O157 infection
Symptoms include diarrhoea, stomach cramps and occasionally fever. About half of people with the infection will have bloody diarrhoea.
People usually notice symptoms three to four days after they have been infected, but symptoms can start any time between one and 14 days afterwards.
These symptoms can last up to two weeks.
A small number of people with E. coli O157 infection go on to develop a serious condition called haemolytic uraemic syndrome (HUS). This can sometimes lead to kidney failure and death, although this is rare. The risk of HUS is highest in children aged underfive years.
Some people become infected but don't develop symptoms.
