Systemic Conditions in Birds
Systemic Conditions in Birds
Some bird diseases affect the whole bird rather than one organ system — including viral illnesses such as PDD (avian bornavirus) and polyomavirus. Each guide covers what to do next, when to call a vet, and which older articles to read. They are not diagnoses.
Vet-first. Systemic viral diseases are clinic-level. Pet Mega Mart does not sell cures or the injectable polyoma vaccine. Supportive care education only — the guides below help you decide when to call a clinic.
Guides
PDD (Proventricular Dilatation Disease)
Undigested food, weight loss, or neurologic changes linked to avian bornavirus.
