During the past week, ECDC kept monitoring an ongoing outbreak of Salmonella Stanley in several EU countries. From 1 August 2011 to 14 September 2012, 402 cases of S. Stanley have been reported on the Epidemic Intelligence Information System (EPIS). Considering the high diversity of S. Stanley observed in the historical databases, the occurrence of one single Pulsed-Field Gel Electrophoresis (PFGE) strain from different countries suggests a multinational outbreak related to a common persisting source of infection. ECDC will keep working with the Member States on the epidemiological investigation.
The Health Protection Agency (HPA) reported on 10 September an additional fatal case of a person who injected heroin and died from anthrax infection in a Blackpool Hospital. This brings the number of cases of anthrax among injecting drug users (IDUs) in Europe to 10, including four fatalities. The conclusions of the rapid risk assessment published by ECDC and EMCDDA in February 2010 and updated on 13 July 2012 remain valid. The risk of exposure to contaminated heroin for IDUs remains present, and accidental contamination is the most plausible explanation.
Between 7 and 13 September, Greece has reported 11 new cases of West Nile fever (WNF). Romania reported one new case and Italy nine. In countries neighbouring the EU, 46 new cases were notified by various federal regions of Russia, 17 new cases were reported from Serbia and Croatia reported three cases, which are the first human WNF in the country this year.
