In addition, the Centers for Disease Control and Prevention in Atlanta, United States of America, had earlier published information on 2 cases of HUS in the United States linked to this outbreak.

All except 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 or, more precisely, a strain of enteroaggregative verocytotoxin-producing E. coli (EAggEC VTEC) O104:H4. All of the affected countries are reporting their cases to the German authorities and WHO. European Union countries are also sharing information through the secure Early Warning and Response System (EWRS).

Note

EHEC and HUS have exclusive notification categories, so case numbers should not overlap. The figures in any rapidly evolving outbreak, however, are provisional and subject to change for a variety of reasons.
