Causes
A mutation of the feline enteric coronavirus (common and harmless) within the cat itself. More frequent in young cats, cats from breeders or those living in groups, and in stressful situations.
Diagnosis
Diagnosis is complex: a combination of clinical signs, blood tests, analysis of the abdominal fluid and specific tests.
Treatment
Until recently it was almost always fatal. Today antivirals (based on GS-441524) exist that have greatly improved the prognosis. Treatment is lengthy and must be supervised by a vet.
Prevention
Difficult to prevent. Reduce stress, avoid overcrowding of cats, and maintain good litter tray hygiene.
