Outbreaks of cryptosporidiosis have been attributed to contaminated drinking water, recreational water, person-to-person transmission, and some food materials. The number of cryptosporidiosis cases associated with recognized outbreaks probably represents only a small fraction of all cases occurring in a community over time. Thus the disease burden and related public health costs of sporadic cryptosporidiosis may be more significant than for outbreaks. The primary focus of international research to date has been the cause of outbreaks of cryptosporidiosis though it is also vital to identify the risk factors for sporadic disease to develop appropriate public health responses for reducing disease rates. This chapter presents a set of case-control studies conducted between 1998 and 2001 to assess risk factors for sporadic cryptosporidiosis in Melbourne and Adelaide. The studies carefully assessed drinking water because of the potential importance of population exposure via this route.
