Seasonality data are not displayed for all FoodNet sites. As a result, totals for this figure may not match totals displayed in other parts of FoodNet Fast. Users should be aware of this limitation before using these data for analysis.
Incidence per 100,000 of post-diarrheal HUS in children by age group and sex for FoodNet sites
Percentage of pediatric, post-diarrheal HUS patients in FoodNet sites having evidence of STEC, by year

Percentage of pediatric, post-diarrheal HUS patients, by laboratory testing method used
Number of HUS patients among those with culture-confirmed STEC infection, by serogroup
* Evidence of STEC includes cases that are culture confirmed, serology positive, or Shiga toxin positive only.
† O157 and non-O157 includes cases that are confirmed to have O157 and one or more non-O157 serogroups
‡ Multiple non-O157 includes any combination of non-O157 serogroups
Evidence of STEC includes all HUS cases that have tested positive for STEC by one or more methods of testing. Shiga toxin positive only includes testing by Immunoassay and/or PCR for Shiga toxin or the genes that produce it. The pie graph breaks down evidence of STEC by testing method and no evidence. These designations are mutually exclusive; therefore,
  • Culture confirmed: shows the percentage of patients who tested positive for STEC infection by culture. Culture-positive STEC infections are Shiga toxin positive. Patients may also be positive for STEC O157 by serology.
  • Serology positive: shows the percentage of patients who tested positive for STEC O157 by serology. These patients do not have a culture-confirmed STEC infection but they may have tested positive for Shiga toxin by other methods.
  • Shiga toxin-positive only: shows the percentage of patients who tested positive for Shiga toxin.
  • No evidence of STEC: shows the percentage of HUS patients who did not test positive for STEC infections. This includes patients who were not tested for STEC infection or who tested negative for STEC infection.
The bar graph displays the serogroups identified for culture confirmed cases.
