The Netter Library is running a long-term trial of GIDEON, the Global Infectious Diseases and Epidemiology Online Network database.
GIDEON is a rich resource, updated daily, for infectious disease, epidemiology, and microbiology information. The platform features tools for finding disease, drug, vaccine, microbe, and country-specific information; identifying pathogens; performing diagnoses; and visualizing epidemiological data, including disease outbreaks and vaccine coverage. At their website, in the “More” section, GIDEON also contains books on infectious diseases in specific countries, specific diseases globally, and major topics in the study of infectious diseases and epidemiology (as well as sample lesson plans).
A brief overview is available at https://www.gideononline.com/features/, and there is a lot of info on their Help page, including videos. A mobile version is also available.
