Confirmed cases are laboratory confirmed and may or may not fulfil the clinical criteria as described in the case definition. For the majority of these confirmed VTEC cases, the clinical outcome was not reported: the case fatality was not reported for 52% of these cases, hospitalization was not reported for 90% and haemolytic uraemic syndrome (HUS) status was unknown for 41%. The clinical manifestation (expressed as bloody diarrhoea, diarrhoea or asymptomatic) was not reported for 47% of the cases. Percentages of cases are given within parentheses based on rows ( ) and within square brackets based on columns [ ].
Seropathotype A includes O157:H7, O157:NM; seropathotype B includes O26:H11, O103:H2, O111:NM, O121:H19, O145:NM; seropathotype C includes includes O91:H21, O104:H21, O113:H21, O5:NM, O121:NM, O165:H25; seropathotype D includes O7:H4, O69:H11, O103:H25, O113:H4, O117:H7, O119:H25, O132:NM, O146:H21, O171:H2, O172:NM, O174:H8, Orough:H2; seropathotype E includes O6:H34, O8:H19, O39:H49, O46:H38, O76:H7, O84:NM, O88:H25, O98:H25, O113:NM, O136:H12, O136:NM, O153:H31, O156:NM, O163:NM; NLK, serotypes that were fully serotyped but were not listed by Karmali et al. [11]; NFT, strains that were not fully serotyped.
