As of 25 June, there have been a further 19 cases associated with the recent outbreak of STEC O145 since the last update a week ago, bringing the total number of confirmed cases to 275 in the UK. All currently confirmed cases had symptom onset dates before 4 June. Although case reporting rates are declining, we expect to see more cases linked to this outbreak as further samples are referred to us from NHS laboratories and whole genome sequencing is conducted.

Confirmed case totals:

  • 182 in England
  • 58 in Scotland
  • 31 in Wales
  • 4 in Northern Ireland (evidence suggests that they acquired their infection in England)

Based on information from 249 cases to date, 49% were admitted to hospital.

Through surveillance, UKHSA has identified 2 individuals in England who died within 28 days of infection with the STEC outbreak strain. Based on the information available from health service clinicians one of these deaths is likely linked to their STEC infection. Both individuals had underlying medical conditions. The deaths occurred in May.
