  • Investigating Syndromic Peaks Using Remotely Available Electronic Medical Records

    Content Type: Abstract

    One limitation of syndromic surveillance systems based on emergency department (ED) data is the time and expense to investigate peak signals, especially when that involves phone calls or visits to the hospital. Many EDs use electronic medical… read more
