At the end of the Halo 3 campaign, Master Chief destroys the ring while he is on it, during which much of the flood died. However, I find it hard to believe that 100% of the flood population was on the ring when it blew up, yet the flood is never mentioned again. If the flood is an infection, then it just needs a little bit of itself to survive for it to start infecting hosts again.

The resulting thermonuclear detonation severed the ring world, destroying it and its life support capability to annihilate all sentient life, and simultaneously killed all remaining Flood on Installation 04, along with any other life forms that were on the ring.

How did the flood survive Halo 3?

Basically, the Forerunners couldn't come up with a way to kill the Flood entirely so they settled on killing their food supply to starve the Flood into hibernation until a day where either Forerunner survivors or some future race found a way to definitively destroy the Flood.

Are the flood dead Halo?

Even though the Gravemind was destroyed, and all Flood on the Ark apparently eradicated, the Flood still existed on the other Halo rings (excluding Installation 05 which was sterilized by Sangheili forces) and other remaining Forerunner installations.
