Spatial Epidemiology

The spatial distribution of cases of disease often captures the imagination of health researchers and the general public, based primarily on the notion that the observed pattern of incidence or prevalence can provide insight in to the underlying mechanisms driving disease incidence, its progression, and the design and implementation of effective public health responses. Historical examples incl...

Cholera and Spatial Epidemiology

Cholera is an acute intestinal infection caused by the water borne bacteria Vibrio cholerae O1 or O139 (V. cholerae). Infection is mainly through ingestion of contaminated water or food (Kelly, 2001). Approximately 102-103 cells are required to cause severe diarrhea and dehydration (Sack et al., 1998; Hornich et al., 1971). Ingested cholera vibrios from contaminated water or food must pass thro...

Page 146ff. Section 3.1.2.1 Different Strategies for Deriving Edge Correction Weights Both, “Stoyan edge correction” and “Ohser edge correction” were published by Ohser and Stoyan (1981). The Stoyan edge correction is also called “translation edge correction”, and the “Ripley edge correction” is also called “Isotropic edge correction”. An early summary of edge correction methods is given in Rip...

Spatial statistics in environmental epidemiology

The planet earth is rich in carbon, oxygen, and hydrogen; it is third from the sun in an orbit that delivers just the right amount of heat and light; and it travels through space with a thin shell of protective ozone that has been crucial to the evolution of terrestrial-based organisms. Our environment has in recent times been seen as delicate and not to be taken for granted. The study of the i...
