Household transmission of haemolytic uraemic syndrome associated with Escherichia coli O104:H4, south-western France, June 2011.

Following the outbreak of haemolytic uraemic syndrome (HUS) on June 2011 in south-western France, household transmission due to Escherichia coli O104:H4 was suspected for two cases who developed symptoms 9 and 10 days after onset of symptoms of the index case. The analysis of exposures and of the incubation period is in favour of a secondary transmission within the family. Recommendations should be reinforced to prevent person-to-person transmission within households. Euro Surveillance. 2011;16(31):pii=19934.
