Summary

This summary is machine-generated.

Chronic wasting disease (CWD) modeling has grown since the 2000s, but research has been limited in scope. Future CWD studies need broader approaches and better diagnostics for effective wildlife disease management.

Area of Science:

Wildlife epidemiology
Prion disease research
Ecological modeling

Background:

Chronic wasting disease (CWD) is a fatal prion disease affecting cervids.
Understanding CWD transmission dynamics is crucial for wildlife management.

Purpose of the Study:

To conduct a meta-analysis of Chronic Wasting Disease (CWD) epidemic models.
To assess historical analytical methods and identify research gaps in CWD modeling.

Main Methods:

Meta-analysis of peer-reviewed articles on CWD published from 1980 to 2018.
Analysis of 14 standardized variables assessing analytical approaches, data, and modeling methods.

Main Results:

CWD modeling increased significantly after the early 2000s, with a concentrated research community.
Studies predominantly used regression and compartment models, focusing on single populations and game species.
Research neglected community ecology and biogeographic approaches; detection methods had limited sensitivity.

Conclusions:

Past CWD modeling provides a foundation for understanding prion ecology in wildlife.
Future research requires more sensitive diagnostics and broader ecological/biogeographic approaches.
CWD prion transmission may differ from other wildlife pathogens, necessitating novel modeling assumptions.
