Overview
Pacheco's Disease is a highly contagious and often fatal viral infection affecting parrots and other psittacine birds. Caused by the Psittacine Herpesvirus, it primarily attacks the liver, leading to rapid deterioration and often sudden death. Due to its severe nature, swift veterinary intervention is crucial.
Causes
Pacheco's Disease is caused by the Psittacine Herpesvirus, which spreads quickly among birds, especially in aviaries and pet stores where close contact facilitates transmission. Stress, overcrowding, and the introduction of new birds are common triggers for outbreaks.
Symptoms & Signs
Early Symptoms
- Lethargy
- Reduced appetite
Advanced Symptoms
- Diarrhea
- Yellow discoloration of droppings (indicative of liver issues)
Emergency Signs

- Neurological symptoms such as tremors or seizures
Diagnosis
Diagnosis of Pacheco's Disease involves blood tests and liver biopsies to detect the presence of Herpesvirus. PCR testing is also a reliable method for confirming the infection.
Treatment Options

Prognosis & Recovery
The prognosis for Pacheco's Disease is often poor due to its rapid progression. Early intervention can improve chances, but many birds do not survive. Recovery time varies if the bird responds to treatment.
