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. These pages are decision guides for owners: what to do next, when to call a vet, and which older educational guides to read. They are not diagnoses.
Vet-first. Systemic viral diseases are clinic-level. Pet Megamart does not sell cures or the injectable polyoma vaccine. Supportive care education only — both decision pages below are product-free.
Decision guides
PDD (Proventricular Dilatation Disease)
Undigested food, weight loss, or neurologic changes linked to avian bornavirus — product-free decision page. Soft-links older PDD digestive guide.
Polyomavirus
Especially concerning in young birds / nurseries — product-free (no injectable vaccine in catalog). Ends at vet-first guidance.
