Syndromic surveillance focuses on what?

• A. One or more symptoms rather than physician-diagnosed or laboratory-confirmed disease
• B. A single laboratory-confirmed disease
• C. Mortality rates only
• D. Hospital admissions data only

Answer: (A)

Syndromic surveillance focuses on monitoring symptoms and patterns in health data rather than waiting for physician-diagnosed or laboratory-confirmed disease. By tracking pre-diagnostic indicators—such as fever with cough, gastrointestinal symptoms, or changes in over-the-counter medication sales—across multiple sources like emergency department visits, urgent care, hotlines, and retail data, public health teams can spot unusual increases quickly and respond early. This approach is broader and faster than relying on a single confirmed disease, mortality data, or hospital admissions alone, all of which can delay detection of emerging outbreaks.
