EHEC outbreak: Update 6 (04-06-11)



04-06-2011


These are the current figures for the outbreak. Enterohaemorrhagic Escherichia coli (EHEC) and haemolytic uraemic syndrome (HUS) have exclusive notification categories, so case numbers should not overlap.

The figures in any rapidly evolving outbreak are provisional, however, and subject to change for a variety of reasons.

• As of 02 June at 15:00 CET, Germany had reported 520 cases of HUS, including 11 fatalities: 50 more than the previous day. 70% of the cases were in females and 89% in adults aged 20 years or older.
• As of 02 June 15:00 CET, 1213 cases of EHEC infections (without HUS) had been reported in Germany, 6 of them fatal: 149 more than the previous day. Of those cases, 61% were in females, and 88% in adults aged 20 years or older. Case onset dates for EHEC ranged from 1 to 30 May.
• As of 03 June 18:00 CET, 11 other European countries (see table) had reported a total of 31 HUS (1 fatal) and 70 EHEC cases (0 fatal).

• All but 1 of the above HUS and EHEC patients had travelled to or from Germany during the incubation period for infection, typically 3?4 days after exposure (range 2?10 days). An increasing number of cases is laboratory confirmed as EHEC serotype O104:H4.
