Assessing the risk posed by oocysts in drinking water

A recent study of infection and illness in human volunteers subjected to controlled exposure to oocysts of Cryptosporidium parvum provided a suitable data base for dose-response analysis. The authors analyzed the study data, and using exponential and beta-poisson dose-response models, arrived at an estimate of the waterborne concentrations associated with various risk levels.
