A definite morbid (illness producing) process having a characteristic train of symptoms or
signs: it may affect the whole body or any of its parts and its aetiology, pathology and
prognosis may be known or unknown.
Disease can be divided into two main categories
1. Acute - of sudden onset and short duration
Outcome - a. causes death of the animal, or
- b. resolves due to host defence response or clinical therapy, or
- c. becomes chronic disease
2. Chronic - of insidious onset and protracted course
Outcome - a. progressively destroys tissue compromising its function and endangering life,
or
- b. its course is halted and the tissue repairs by scarring
