  1. Acute giardiasis : an improved clinical case definition for epidemiologic studies.

    Article - En anglais

    In June 1983, an outbreak of waterborne giardiasis occurred in a group of 93 university students and faculty participating in a geology field course in Colorado.

    All cases occurred in one subgroup of persons who were heavily exposed to untreated stream water on a field trip, and the risk of illness was strongly related to the amount of untreated stream water consumed.

    The median incubation period from a brief exposure to the first symptom was 7 days.

    The authors compared symptoms and stool sample results among 31 Giardia-positive persons in the exposed group and 36 Giardia-negative participants in an unexposed group to assess several case definitions for acute giardiasis.
