Traduction en anglais : Environmental investigations of asymptomatic kindergarten children as sources of enterohaemorrhagic escherichia coli (EHEC) in the Ammerland district.
The increase of serious EHEC diseases in the northwest Lower Saxony in summer 1997 was accompanied by a lively discussion on the hazard represented by this pathogen which gained a large amount of media attention.
The Lower Saxony Public Health Department initiated a study of this case in the Weser-Ems government district to investigate the spread of EHEC by children and their supervisors in kindergartens receiving certified raw milk supply.
This established that there were ten kindergarten children in the Ammerland rural district who were asymptomatik EHEC carriers.
The Local Public Health Department immediately carried out the necessary epidemic hygiene measures.
First of all, control investigations were performed on the affected children, including environmental investigations on their families and contracts.
The results of these investigations revealed the need to carry out additional environmental investigations in two kindergartens (follow-up investigations) as well as amongst employees in a hospital canteen.
Within the families, a mother of an affected child was also identified as another asymptomatic EHEC carrier.
However, the strains that were isolated reflected different serotypes.
In total, the investigation of 337 people in contact with the eleven asymptomatic EHEC carriers did not confirm any person-to-person transmission - even though three of the kindergarten children shedding the organisms for 6-10 weeks attented the kindergartens for at least 4 weeks. (...)
