Document Summary
The ecology of disease: parasites and pathogens, disease dynamics, compartmental models for disease. Pathogens and parasites: function to create limited population growth, the growth of pathogen is limited by their own capacity to grow as well as dependent on the life history of their host. Pathogen transmission: direct (sick person touching other person) vs indirect (blowing your nose and then touching the door handle) physical component passing disease to children such as hiv, horizontal (giving someone a cold) vs vertical (between generations, parents. Describing disease population growth: susceptible (uninfected, this is beta (per capita rate of transmission, it is important in terms of. Infected: this is symbol, susceptible--host death (d per capita death rate is related to aging) Infected host death (d+a how death rate is affected by disease, the a value is increased, how much more likely you are to die) Birth (fig 15. 11: making the assumption if you are born, you are not getting the disease.
