Scan summary
The September 26 scan reverified every active signal against its authoritative primary sources. No new event met the desk's sourcing threshold to be added, and no material change was found to the signals already tracked. The 11 active point signals — plus one global Watch layer — were retained unchanged. This absence of additions reflects the desk's deliberately selective bar, not an absence of public-health risk worldwide.

How this scan was run
Each twice-daily scan pulls the latest outbreak, recall, and climate-health bulletins from a fixed set of authoritative primary sources, normalizes and de-duplicates them against what is already live, and compares them to the current desk. A record is added, updated, or removed only when a current authoritative source supports the change; otherwise it is reverified and retained. This edition recorded no qualifying additions, updates, or removals.

This edition is situational awareness for public-health professionals and the public. It is not medical, clinical, or travel advice. Every signal is reverified against its authoritative primary sources; the desk adds a record only when a current source supports it, so an absence of new signals never implies an absence of global health risk.
