Scan summary
The September 30 scan holds 15 active signals: 4 added, 2 updated, 9 retained, and 0 removed. No new qualifying international emergency was first published on September 30. The scan identified and added one still-active U.S. foodborne outbreak that had not been incorporated into the earlier unapproved packages: the multistate Salmonella Bovismorbificans outbreak linked to recalled broccoli sprouts. The scan carries forward verified Bangladesh dengue, European West Nile virus, raw-milk-cheese E. coli, and the Nepal flood-health update, and materially updates the Democratic Republic of the Congo Bundibugyo Ebola operational response. Nine previously published signals were retained without a material change. The El Niño–Southern Oscillation watch remains a separate global layer and is not included in the 15.

How this scan was run
This edition compared the latest WHO, ECDC, CDC, and FDA publications with the live desk. Event date, authority publication or update date, TiPH detection date, and TiPH publication date are stored separately and are not substituted for one another. A record was added or updated only when a current authoritative source supported a material change. Nine previously published signals were reverified and retained; their TiPH modification dates were not changed. One still-active U.S. foodborne outbreak that had not been incorporated into the earlier unapproved packages met the inclusion threshold and was added. No signal was removed.

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.
