CDC investigates mystery E. coli outbreak
The US Centers for Diseases Control and Prevention (CDC) is investigating a multistate outbreak of E. coli O145 infections, the source of which is currently unknown.
The outbreak has affected at least 14 people in six states since 15 April, with one death and three hospitalisations. Although ten of those affected have been interviewed as part of the investigation, the source of infection has not been identified as yet.
There have been no new cases reported for more than a month, suggesting that the outbreak may be over. However, the CDC investigation into the source is continuing.
