  1. Waterborne outbreaks of cryptosporidiosis.

    Article - En anglais

    Cryptosporidium parvum infection occurs worldwide in urban and rural populations, and waterbome outbreaks have been associated with consumption of contaminated drinking water and water during recreational activities.

    This article reviews the epidemiology and causes of waterborne outbreaks that have been reported in North America and the United Kingdom.

    Outbreaks were associated with filtered and unfiltered surface water sources, ground water sources, and contamination of the distribution system.

    In most outbreaks, sources of contamination and deficiencies in treatment and operation were identified.

    Available epidemiological information is inadequate to estimate endemic waterborne risks, and analytical studies shoul be conducted to assess these risks.

    A major issue to consider in assessing waterborne cryptosporidiosis risks is the role of protective immunity, which may be acquired through low-level sporadic exposures to C. parvum in drinking water.
