Fig 1.
Epicurve of EHEC O104:H4 Outbreak in Hamburg, Germany.
Shown are EHEC and HUS cases according to date of symptom onset (boxes, n = 656) and notification date (line, n = 554). The last outbreak-associated case fell ill on July 4, 2011. The arrow indicates the day when RKI was informed of a cluster of three pediatric HUS cases admitted to the Hamburg University Hospital.

Age and Sex Distribution of EHEC and HUS Cases during EHEC O104:H4 Outbreak in Hamburg, 2011.
Nine age groups were defined for EHEC cases (upper panel, n = 482) and HUS cases (lower panel, n = 174).

Spatial Distribution of EHEC/HUS Incidences of Hamburg during EHEC O104:H4 Outbreak 2011.
Street addresses of EHEC/HUS cases were mapped and incidences (cases per 10,000) calculated for 100 districts of Hamburg. Incidences were categorized in six groups as shown.
Fig 4.
EHEC/HUS Incidence Distribution in 100 Districts during EHEC O104:H4 Outbreak in Hamburg, 2011.
Incidences (cases per 10,000) were categorized in 21 groups as indicated.
