Townsville Public Health Unit is responding to a shigella outbreak at Richmond State School where there have been 12 confirmed cases.

Shigella infection is a serious form of gastroenteritis caused by a bacterium that attacks the intestines leading to diarrhea, abdominal pain or cramps and fever.

The illness is spread if you accidentally swallow the bacteria that is found in faeces, usually through not washing your hands properly after going to the toilet or changing diapers.

Townsville Public Health Unit physician, Dr Julie Mudd said additional cleaning was being undertaken at Richmond School today as it is closed for a public holiday.

Of the 12 cases, one was brought to Townsville University Hospital as a precaution and has since been discharged. The remaining 11 cases are recovering in the community.

Denmark – Imported, fresh mint linked to Shigella outbreak

Outbreak News Today

The Statens Serum Institut (SSI) has in collaboration with the Danish Veterinary and Food Administration and the DTU Food Institute report that a Shigella outbreak in August and September that sickened some 44 people is linked to fresh mint bought at a local greengrocer or bazaar in and around the Copenhagen area.

Of the 44 cases from August 22 to September 9, 30 of the cases was reported in women and 14 in men. A total of 13 people have been hospitalized. The sick live primarily in the Capital Region.

Because fresh mint has a short shelf life, it is no longer on the market. There is therefore no risk of more consumers becoming infected, says Emergency Manager Nikolas Kühn Hove from the Danish Veterinary and Food Administration.

More than 40 people are sick and almost a third have needed hospital treatment as part of a foodborne Shigella outbreak in Denmark.

From the end of August, 42 people have been registered with shigellosis in the country.

The outbreak is being investigated to try to pinpoint the source of infection and help stop it with experts doing final traceback investigations ahead of plans to reveal results next week.

From Aug. 25 to Sept. 10, 42 cases of shigellosis were reported to the Statens Serum Institut (SSI).

 

Research – Association between Shiga Toxin–Producing Escherichia coli O157:H7 stx Gene Subtype and Disease Severity, England, 2009–2019

CDC

Abstract

Signs and symptoms of Shiga toxin–producing Escherichia coli (STEC) serogroup O157:H7 infection range from mild gastrointestinal to bloody diarrhea and hemolytic uremic syndrome (HUS). We assessed the association between Shiga toxin gene (stx) subtype and disease severity for »3,000 patients with STEC O157:H7 in England during 2009–2019. Odds of bloody diarrhea, HUS, or both, were significantly higher for patients infected with STEC O157:H7 possessing stx2a only or stx2a combined with other stx subtypes. Odds of severe signs/symptoms were significantly higher for isolates encoding stx2a only and belonging to sublineage Ic and lineage I/II than for those encoding stx2a only and belonging to sublineage IIb, indicating that stx2a is not the only driver causing HUS. Strains of STEC O157:H7 that had stx1a were also significantly more associated with severe disease than strains with stx2c only. This finding confounds public health risk assessment algorithms based on detection of stx2 as a predictor of severe disease.

Europe – Shigellosis – Annual Epidemiological Report for 2017

Shigella - kswfoodworld

Shigellosis is a relatively uncommon disease in the European Union/European Economic Area (EU/EEA), but remains of concern in some countries and for some population groups. For 2017, 30 EU/EEA countries reported 6 337 confirmed shigellosis cases. The overall notification rate was 1.7 cases per 100 000 population, slightly higher than in 2016. The highest notification rate was observed in children below five years of age, followed by male adults aged 25–44 years. Sexual transmission of shigellosis among men who have sex with men (MSM) is thought to have contributed to the gender imbalance in the latter group.
