Syndromic surveillance may, however, still play an important role in rapidly... Read more

Content type: Abstract

Many studies evaluate the timeliness and accuracy of outbreak detection algorithms used in syndromic surveillance. Of greater interest, however, is defining the outcome associated with improved detection. In case of a waterborne cryptosporidiosis outbreak, public health interventions are aimed... Read more
