IDdx: Infectious Disease Queries

March 2019


Country of origin: USA

IDdx was built for queries. Users can find lists of matching infectious diseases by picking disease search criteria. The user can see all the symptoms associated with a disease or see all the diseases associated with a symptom.

New features added in January 2015 are Ranked Diseases and Weighted Findings. Ranked Diseases means that the user can sort the list of diseases returned from a query by cases/years in either the U.S. or worldwide. Weighted Findings means that color coding indicates how frequently a finding is used to describe the disease in the twelve primary references. The findings of a disease are included only if they are published in the primary references. Weighted Findings enables another new feature: Query Sensitivity. Choose High to get the most diseases that match one or more signs & symptoms. Choose Low to get only those diseases in which the finding was cited in three or more of the 12 references. Background updating gives users the latest information on a daily basis--no manual updating of the app required.

- Explore the database of 250 diseases in 15 categories.
- Search by disease Name or Criteria.
- Disease criteria include 104 signs & symptoms, 39 epidemiological factors, and 16 regions of the world.
- Search by Occupation. Results are sorted by high-risk job tasks.

- Examples of epidemiological factors are ingest (entry), soil (source), ticks (vector), and cats (reservoir).
- Access diseases worldwide or limit the search to those endemic to the United States.
