Tele-epidemiology is an area of epidemiology which is related with spatial systems like GIS and Remote sensing that can be used for studying spatio-temporal distribution of diseases. This can be used to study human and animal epidemics, the spread of which is correlated to environmental factors.
By combining various data originated from satellites along with GIS data and clinical data from humans and animals, predictive models can be constructed. This area of epidemiology is also very useful in the study of recent outbreak of West Nile virus in the state of Texas.
- Hotspot analysis indicates place vulnerability and reveals the presence of a statistically significant grouping of cases. It also indicates the area of probable virus introduction.
- Tele-epidemiological models aid in rapid entry point identification and spatial prediction of human risk of infection for introduced vector-borne pathogens using cost effective tools. They are useful for fighting future disease outbreak by allocating sufficient resources in the hot-spot regions.
