The general definition for Epidemiology
is the study of disease ecology
Epidemiology is a specialized sub-discipline of
ecology and is included under the larger umbrella definition of ecology
Ecology
ecology – which is the study of how organisms interact with their environment.
(Autecology)
Some traditional sub-disciplines of ecology includes studies of single species
(Population Ecology)
populations of single species
(Community Ecology)
assemblages of the different species
(Ecosystem Ecology)
multiple communities
Epidemiology only includes
The natural history of diseases,
Concepts that serve to unify the pattern of information needed to understand the epidemiology of vector –borne diseases.
Discovery of what causative agent (parasite).
Understand the epidemiology of vector-borne diseases
Identifying the mode of transmission among vectors and vertebrate hosts.
Understand the epidemiology of vector –borne diseases
Monitoring.
Understand the epidemiology of vector –borne diseases
Forecasting
Understand the epidemiology of vector –borne diseases.
Control
Vector-borne diseases include 3 important components:
The Arthropod Vector (Insect or Arachnid)
Vector-borne diseases include 3 important components:
A Vertebrate Host
Vector-borne diseases include 3 important components:
A Parasite (Protist, Virus, Bacteria, or Nematode)
What allows accurate prediction of the risk of arthropod-borne diseases to humans and animals?
Vertebrate host, Arthropods vector and Parasite
Understanding parasite-host interactions is helpful in?
developing therapeutic measures and diagnostic test.
Major components of the Arthropod-borne Disease Triad are all accept
1.) The Arthropod Vector 2.) A Vertebrate Host 3.) A Parasite 4.) structure
Major components of the Arthropod-borne Disease Triad are all influenced by several critical environmental variables.
1.) Temperature (both air and water) 2.) Precipitation Patterns 3.) Structure of Suitable Habitats: Terrestrial & Aquatic
4.) Distribution of Suitable Habitats: Terrestrial & Aquatic
5.) Abundance of Suitable Habitats: Terrestrial & Aquatic
