Syndromic Surveillance for Early Event Detection with Real Time Online Disease Surveillance (RODS) Houston Department of Health and Human Services Wes McNeely MS, MPH, Epidemiology Supervisor (PHP) A.J. Rosario MD, MPH Systems Analyst (PHP)
Syndromic surveillance for early outbreak detection is an investigational approach where health department staff…monitor disease indicators continually (real-time) or at least daily (near real-time) to detect outbreaks of diseases earlier and more completely than might otherwise be possible with traditional public health methods. The distinguishing characteristic of syndromic surveillance is the use of indicator data types.
“ In signal detection theory, a receiver operating characteristic (ROC) is a graphical plot of the sensitivity (fraction of true positives - TP) vs. 1-specificity (the fraction of false positives - FP) for a binary classifier system as its discrimination threshold is varied.” http:// en.wikipedia.org/wiki/ROC_Curve
