Syndrome data are inherently non-specific and not based on diagnostic testing. While the New York City syndromic surveillance system captures 100% of all emergency department(ED) visits in the city (as of 5/1/16, 99% prior to that), the data are not comprehensive as only aproportion of residents seek care in emergency departments. Therefore the data are not exact measures of morbidity.
