Public Health England has identified links between 17 cases of Shigella sonnei (of which eight cases have been in London). The strain identified is a concern due to its multi-drug resistance. Standard treatment may not be effective.
Due to the highly drug resistant nature of this strain PHE asks practices to complete the GI enhanced shigellosis questionnaire for all cases (prospective and retrospective) that meet the case definition in the attached notice.
The questionnaire can be downloaded here – completed questionnaires should be emailed to the PHE Shigella inbox.
