Histoplasmosis in Travelers

In 2019, several Canadian tourists acquired histoplasmosis while exploring caves in Cuba.  The Gideon database maintains an ongoing record of all cross-border Infectious Diseases events, including importation of animals and foods associated with zoonotic disease. [1-3]

As of 2019, 76 episodes of histoplasmosis had been associated with travel, involving at least 574 individual cases (8 fatal).  18 of these events were related to cave exposure, including two involving caves in Cuba.  Four publications described acquisition of histoplasmosis by Canadian travelers – two involving cave exposure.

In the following screen-shot, the frame to the left displays an interactive chronicle of cross-border histoplasmosis.  Users can sort data by year of event, country of exposure / origin, etc.  In this example I’ve selected “Setting” in order to study cases related to “cave exposure.”  Additional details and electronically-linked references appear when the user clicks on “Show event notes”

A Global Web-based System for Disease Simulation and Informatics in the Field of Geographic Medicine

Stephen A. Berger, M.D.

347 generic infectious diseases are distributed haphazardly in time and space; and are challenged by 342 drugs and vaccines. Over 3,000 pathogenic bacteria, viruses, parasites and fungi have been described in human disease. An ongoing project for decision support and informatics will serve as a paradigm to demonstrate an approach to web-based systems for Geographic Medicine. The first module in the program generates ranked differential diagnoses based on signs, symptoms, laboratory tests, exposure history, country of acquisition and incubation period; and can be used to diagnose or simulate any infectious disease scenario. Additional capabilities include bioterrorism simulation and syndromic surveillance. The second module follows the epidemiology of individual diseases, including their global status and occurrence in each endemic country. As of 2010, this module contains 3 million words of text in 18,500 country-specific text notes; 32,095 graphs; 5,100 images (clinical, microscopic, life cycle, etc); 345 maps; 150,000 linked references; 10,200 outbreaks and 21,101 disease prevalence and serosurveys. The third module follows the pharmacology and usage of all anti-infective drugs and vaccines. The fourth module is designed to identify and characterize all species of bacteria, mycobacteria and yeasts. Application of such systems for use in diagnosis, surveillance and education will be discussed. Since all data in the program are generated at the server level from modular sources in electronic spread sheets, a subprogram has been designed to generate entire text-books (e-books) on the diseases of individual countries and diseases. At present, 411 such books (95,000 pages) have been generated – all of which will be updated yearly.


On Monday, November 8th, GIDEON’s medical director, Steve Berger, MD will be on the Global Access to Infectious Disease Information panel at the American Public Health Association (APHA) meeting in Denver, Colorado. Following that he will demonstrate GIDEON at a session entitled: Web-based system for informatics and decision support in geographic medicine.
