Officials in Denmark are investigating a deadly outbreak of Shiga toxin-producing E. coli (STEC) O157 that has affected more than a dozen people.
The outbreak began in December 2021 and includes 13 patients with a possible common source of infection, said the Statens Serum Institut (SSI). Nine people have been hospitalized and an elderly patient has died.
Since early December, 13 patients have been detected and samples from nine of those sick are closely related after an analysis by whole genome sequencing at the Statens Serum Institut. This means they were likely infected by a common source.
