The Wildlife Disease Positives Software allows the user to track the occurrence, persistence, or spread of diseases in free-ranging wildlife. The R scripts of the Wildlife Disease Positives Software are executed in sequence to (1) summarize testing (surveillance) data by county in a US state or Canadian province of interest, (2) summarize positivity rate by designated administrative area (county, census divisions) in the state or province of interest, (3) summarize testing effort and positivity rate by age (fawn, yearling, adult, all deer), sex (male, female), and year (2013-2025), (4) summarize testing data and positivity rates for contiguous states and provinces when available, (5) and display the results via interactive maps in a user interface (UI). The Wildlife Disease Positives Software packet includes (redacted) disease testing data and example apps from a select assortment of United States wildlife agencies: Alabama, Arkansas, Connecticut, Florida, Georgia, Indiana, Iowa, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Mississippi, New Hampshire, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, Tennessee, Virginia, and Wisconsin and Canadian provincial agencies: Ontario. While the Wildlife Disease Positives Software was designed for use by state and provincial agencies to track chronic wasting disease (CWD) in white-tailed deer (Odocoileus virginianus) from 2013-2025, the software is easily adaptable to other wildlife diseases in other states or provinces, in different years, and/or in differing wildlife species.
