Define syndromic surveillance

What will be an ideal response?

Public health also includes the modeling of disease agents, which is best done by computers. One approach to containing infectious disease currently being explored is called syndromic surveillance, which uses "health-related data that precede diagnosis and signal a sufficient probability of a case or an outbreak." Syndromic surveillance can be used, for example, in shelters where there are no medical personnel; people can look out for signs and symptoms (e.g., diarrhea) and report them. New York City's syndromic surveillance program "looks for unusual patterns of disease in…emergency rooms." The federal government uses "biosensor detectors" in cities to "draw in air and analyze it for…pathogens" to guard against bioterrorism.
