Why consider disease on a population level?
To know true importance of the disease, and hence develop appropriate resource
allocation
In order to estimate costs and benefits of disease control programmes; these simply
cannot be done unless we have knowledge about the disease's behaviour in groups of
animals.
The behaviour of a disease in group will help you diagnose when the clinical evidence
from a single animal is inadequate for full diagnosis
Studying the behaviour and inter-relationships of disease within a population may assist
in the discovery of the causes of the diseases.
Prevention of a disease is better than cure.
