Evaluation of the representativeness of a sentinel surveillance site for campylobacteriosis

open access: yesEpidemiology and Infection, 2014
SUMMARYIt is important to assess the suitability of sentinel sites for human disease; however, there have been few publications documenting the process of formal evaluation. We describe an approach to examining the representativeness of a single sentinel site employed for campylobacteriosis surveillance and source attribution, utilizing a selection of ...
