abstract: Giardiasis has recently been added to the list of infectious diseases whose transmission is favoured by day care centers. This article discusses an epidemic that occurred in a Outremont day care center where the systematic search for parasites in the stool has identified 19 cases of Giardia lamblia in a group of 82 persons at risk, and three additional cases in their families. Sixty-eight percent of the identified cases were asymptomatic. The dissemination process throughout the day care center and the families strongly suggests a person to person transmission. The systematic treatment of all the known carriers seems to have controlled the epidemic. Given the epidemiological date available, control measures against Giardia lamblia in day care centers are recommended.
