Communicable disease threats report, 1-7 December 2013, week 49
The ECDC communicable disease threats report is a weekly bulletin intended for epidemiologists and health professionals in the area of communicable disease prevention and control. Summarising information gathered by ECDC through its epidemic intelligence activities regarding communicable disease threats of concern to the European Union, it also provides updates on the global situation and changes in the epidemiology of communicable diseases with potential to affect Europe, including diseases that are the focus of eradication efforts.
On 8 November 2013, the UK reported an unusual increase in laboratory reports of domestic cases of Salmonella Mikawasima between September and November 2013. Denmark, France, Germany, Spain and Sweden, reported temporally linked domestic cases. Denmark, Sweden and Germany also reported an associated increase above the national average for the period. In a joint rapid outbreak assessment prepared by ECDC and European Food Safety Authority, a multi-sectorial investigation was recommended to understand and assess the risk associated with this increasing trend of Salmonella Mikawasima infections in the EU/EEA. Details of this investigation are being discussed with affected countries. ECDC will continue to monitor the situation.
