Non-O157 findings


Detection of and attempting out for non-O157 STEC elevated. In 2019, 768 culture-obvious non-O157 STEC cases, with 655 in England and 113 in Wales, were reported. Of 5,760 samples got for attempting out, 1,002 non-O157 cases were confirmed in England. Of these, 655 culture obvious cases of 72 serogroups were confirmed.
