How prevalent is the bird flu in the us?

Virtually none seen: This strain of influenza has not been seen in the USA. Cannot say there have been none, but if so, rare. The best way to avoid influenza is through regular yearly vaccination. The CDC tracks the types of flu most commonly seen and those are included in the latest vaccines available.

Rare: Very rare and reportable if found in a human.

Quiet: No problem right now hopefully it will stay this way.
