Usage and data collection patterns for a novel web-based foodborne-disease surveillance system.

This paper discusses the traditional system of foodborne-illness surveillance and provides a justification for increased syndromic surveillance of foodborne illness. A new Internet-based method for reporting foodborne disease is explained, and data entered by 7,500 visitors to the pilot Web site are described with respect to completeness and basic demographic factors. Data entry patterns show that visitors are willing to report a suspected case of foodborne illness online and do so in greater detail than is commonly obtained from traditional reports made over the telephone.
