Epidemiology and Parasitology

Epidemiology is a Medical Speciality which deals with the incidence, distribution, and possible control of diseases and other factors relating to health.
Epidemiology is the study of how often diseases occur in different groups of people and why. Epidemiological information is used to plan and evaluate strategies to prevent illness and as a guide to the management of patients in whom disease has already developed.
Parasitology is a branch of science that is concerned with parasites and parasitism. Parasitism is A form of symbiosis in which one organism (called parasite) benefits at the expense of another organism usually of different species (called host). The association may also lead to the injury of the host. An example of parasitism is the association between the parasitic tapeworms and the vertebrate hosts.
Parasitology has different sub-disciplines:
  • Medical parasitology:- which deals with the human parasites and the diseases caused by them
  • Veterinary parasitology:- which deals with animal parasites
  • Structural parasitology:- which studies the structures of proteins from parasites
  • Quantitative parasitology:- which is the quantitative study of parasitism in a host population
  • Parasite ecology:- which studies the ecological impact of parasites
