Outbreak of giardiasis in a daycare nursery.

Seven children and one member of staff in a nursery in Kent became ill with Giardia lamblia infection in three months in a nursery in Kent and three further children were found to carry giardia. Person to person spread among young children who were not toilet trained appeared to be responsible. All staff and children were screened for infection, and the outbreak was controlled by reinforcing hygiene measures, and treating microbiologically confirmed cases and carriers with metronidazole.
