Shiga toxin-producing E. coli (STEC): Update on outbreak in the EU (27 July 2011, 11:00)

27 Jul 2011

In the EU/EEA, only two non-HUS STEC cases were reported to have fallen ill within the last 10 days (17 July – 26 July), all in Germany. These are two probable cases, not yet confirmed with STEC O104. The last known date of illness onset in a patient with confirmed STEC O104 was 7 July 2011 (see text below). The last reported date of illness onset among all (probable and confirmed) cases was 17 July 2011.

As of today, the cumulative number of confirmed STEC cases in the EU/EEA is 941. This includes 264 HUS STEC cases and 677 non-HUS STEC cases. Additionally, there are 518 probable HUS STEC and 2 451 probable non-HUS STEC cases, with no confirmation of STEC O104 at present time. In total, in the EU, 46 persons have died of confirmed or probable STEC infection. Of these, 29 were HUS STEC cases and 17 were non-HUS STEC cases. The table below shows the distribution of cumulative probable and confirmed STEC cases per country.

The Robert Koch Institute declared on 26 July the outbreak in Germany as officially over (see link below), as the last date of onset for a case with an epidemiological link, was 4 July, three weeks ago. Since the last update on 26 July, Germany has reported nine non-HUS STEC cases and one HUS STEC case. Cases reported with onset after 4 July are considered by Germany as having no epidemiological link with the initial outbreak or for which no laboratory confirmation is available. Other Member States have not reported any new cases since the last update.

Note: the numbers in this table represent the total number of cases reported at the European level (ECDC) so far. Although daily numbers of reported cases have steadily decreased in the last weeks, these cumulative numbers continue to rise due to reporting delays at the various levels.

Suspected cases (Germany: 119 HUS STEC (4 deaths), France: 4 non-HUS STEC) are not included.

* Cases reported from the outbreak in Bordeaux
** Cases reported earlier, linked to travel to Germany
