The prognosis is poor for infected birds with clinical signs
Long term problems
The possibility of a carrier state presents problems for other birds that may come into contact with an infected individual, and this may also result in spread of the disease across Continents through migratory wild birds.

main concerns is that this highly pathogenic avian virus might mutate so that
it can be transmitted readily between humans, and so result in a human
