In this example there are 500 animals in the population at the beginning; all 500 animals are susceptible, there are no clinical infections, and no recovered animals. This means the disease is not present within the population in the beginning.
When the contagious disease is introduced, initially there will be a small number of infected animals. Over time these animals will infect others and the disease will spread within the population. This is shown by the rise in clinical animals (infected animals with clinical signs) and the fall in susceptible animals.
After some time the clinical animals will recover from the disease. The final pattern will depend on how contagious the disease is and how severe it is. If the disease became endemic there would be a constant mixture of susceptible, clinical and recovered animals. The number within these categories will move up and down over time depending on all the causes that influence if disease will occur.
