This map led Snow to identify the contaminated pump and conclude that cholera was a waterborne illness, a remarkable feat given that bacteria were unknown to science at the time. While Snow's contributions to medical geography and epidemiology are irrefutable, the role of the map in this particular investigation is somewhat overstated. [10]
Group concept mapping is a structured methodology for organizing the ideas of a group on any topic of interest and representing those ideas visually in a series of interrelated maps. [ 1 ] [ 2 ] It is a type of integrative mixed method , [ 3 ] [ 4 ] combining qualitative and quantitative approaches to data collection and analysis .
John Snow's cholera map about the cholera deaths in London in the 1840s, published 1854. Another example of early thematic mapping comes from London physician John Snow. Though disease had been mapped thematically, Snow's cholera map in 1854 is the best-known example of using thematic maps for analysis.
Epidemiology has its limits at the point where an inference is made that the relationship between an agent and a disease is causal (general causation) and where the magnitude of excess risk attributed to the agent has been determined; that is, epidemiology addresses whether an agent can cause disease, not whether an agent did cause a specific ...
Disease diffusion occurs when a disease is transmitted to a new location. [1] It implies that a disease spreads, or pours out, from a central source. [2] The idea of showing the spread of disease using a diffusion pattern is relatively modern, compared to earlier methods of mapping disease, which are still used today. [3]
The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
A concept map or conceptual diagram is a diagram that depicts suggested relationships between concepts. [1] Concept maps may be used by instructional designers , engineers , technical writers , and others to organize and structure knowledge .
