Nurse Ann T. Flood was a Starfleet crewmember during the Dominion War.
In 2374, files from Starbase 129 reported Flood missing in action. Files from the starships USS Cochrane, USS Repulse and Starbase 153 reported her killed. (DS9: "In the Pale Moonlight")
Flood's name appeared on the casualty list display seen on a computer readout in that episode. It is unclear which was her home station, if any.
