Abstract
Data pertaining to the Milwaukee outbreak of cryptosporidiosis which affected approximately 400,000 individuals during the period March-April 1993 are reviewed and the probable incidence of Cryptosporidium oocysts in the treated water supplied from the Howard drinking water treatment plant during the same period is estimated. The estimated level, which was derived from an analysis of finished water samples and water in the distribution system together with ice manufactured at the same time was compared with values predicted with the aid of a dose-response model applied to the affected population. The dose-response model indicated the likely presence of oocysts in the concentration range 0.42-4.5 per litre. This value appeared to be in general agreement with the results of observations but with certain corrections since the actual levels encountered were somewhat lower. The comparison assumed a 100 per cent recovery of oocysts from the samples obtained during the outbreak and also that the virulence of the strains employed was similar in all cases, assumptions which were impossible to verify.
