Which program is a data-sharing program used for surveillance of disease patterns in the United States?

• A. BioSense
• B. Public Health Surveillance Network
• C. National Outbreak Reporting System
• D. Global Health Observatory

Answer: (A)

BioSense is the data-sharing program the CDC uses to monitor disease patterns across the United States in near real time. It collects syndromic surveillance data, especially emergency department visit information, from multiple jurisdictions so public health officials can detect unusual activity, track trends, and respond quickly. Over time it evolved into the National Syndromic Surveillance Program, which emphasizes standardized data exchange across states to improve nationwide situational awareness. The other options don’t fit as well: the Public Health Surveillance Network is an older framework for sharing surveillance data, not the primary national system for broad, real-time syndromic surveillance; the National Outbreak Reporting System focuses on documenting outbreaks rather than continuous, nationwide data sharing; and the Global Health Observatory is WHO’s global data portal, not a U.S.-specific surveillance program.
