Role of non-polio enterovirus infection in pediatric hemolytic uremic syndrome.

Verocytotoxin-producing Escherichia coli(VTEC) infections cause most cases of hemolytic uremic syndrome (HUS); 10-30% of patients, however, are negative for VTEC infection. The etiology of HUS in VTEC-negative cases remains poorly understood. Before the association between VTEC infection and HUS was recognized, sporadic cases of HUS with enterovirus infection were reported in the literature.
