[Tweeters] Affected birds

[Greg via Tweeters]

Hello attentive Tweets -
Is there conclusive evidence that birds (seemingly mostly House Finches) with ugly cankers around eyes or on feet, can become well and whole again? Or are they relegated to a slow death all the while spreading their disease by frequenting various feeders? It seems it would be difficult to discern because individual birds are hard to track.

Just wondering,
