Syndromic surveillance using veterinary laboratory data: algorithm combination and customization of alerts.

<h4>Background</h4>Syndromic surveillance research has focused on two main themes: the search for data sources that can provide early disease detection; and the development of efficient algorithms that can detect potential outbreak signals.<h4>Methods</h4>This work combines t...
