Humanitarian Data Exchange vs Open Disease

HDX is OCHA's CKAN-based catalog of over 18,000 humanitarian and public-health datasets (disease outbreaks, health-facility locations, population and displacement data) covering 250+ locations, searchable and downloadable through the standard keyless CKAN Action API (package_list, package_show, datastore_search). A live GET against data.humdata.org/api/3/action/status_show succeeds with no key, and a live Origin-header probe returns Access-Control-Allow-Origin: *, resolving the stored 'unknown' to 'yes'.

disease.sh aggregates COVID-19, influenza, and general public-health case/vaccination data from Johns Hopkins CSSE, WHO, and other public feeds into a single keyless JSON API, with endpoints scoped by country, US state, or continent plus historical time-series. A live GET against disease.sh/v3/covid-19/all and a live Origin-header probe both return Access-Control-Allow-Origin: *, reconfirming the already-stored 'yes'.
