South Sudan: Unknown Hemorrhagic Illness

Regarding an ongoing outbreak of hemorrhagic illness in South Sudan, a differential diagnosis list generated by Gideon [Global Infectious Disease & Epidemiology Network]http://www.GideonOnline.com, includes 2 lesser-known pathogens which have been associated with single small clusters of hemorrhagic fever in Africa: Bas-Congo virus (rhabdovirus) and Lujo virus (arenavirus). In 2008, 4 of 5 patients died of Lujo virus infection in a South African hospital, following transfer of an index patient from Zambia. The following year, 2 of 3 villagers in DR Congo died in an outbreak of Bas Congo virus infection. If tests for other pathogens continue to be negative, these 2 agents might be considered.

Zika

When “Ebola” became a household word for most Americans in 2015, few realized that a more sinister outbreak was unfolding in their own back-yard. Chikungunya, a dengue-like illness which had previously been limited to the jungle areas of Africa and Asia, suddenly appeared in Latin America, resulting in over 2 million cases as of January 2016. And then Zika virus followed in the same region, threatening to attack a similar number of people. Unlike Chikungunya and Dengue, Zika virus infection has now been identified as a major cause of microcephaly (abnormally-small head) and other severe neurological disorders in babies born to women who are infected by Zika virus in early pregnancy.

GIDEON has been closely following Ebola, Chikungunya, Zika … and every other infectious disease – for over twenty five years. Health care profesionals can enter the signs and symptoms of patients from affected countries, and display a comprehensive, ranked list of possible diseases.

Findings of a recent patient treated after returning from Suriname with fever and rash were entered into GIDEON:

Note the red arrows to the right. GIDEON has indeed “considered” that the patient might be suffering from Chikungunya, Dengue, Zika – and a host of other common and lesser-known conditions.

Users can easily access extensive background information on the diseases themselves, including maps, pictures and graphs, or explore their status on the global level, or within individual countries.  In this example, GIDEON compares the clinical features of Dengue, Chikungunya and Zika:

GIDEON maps the current global distributions of these three diseases:

Webinar replay and GIDEON demo

Dr Steve Berger presents a background on Infectious Diseases and using GIDEON as a decision support tool during a webinar earlier today.

Diagnosis Support for Ebola through GIDEON

The Diagnosis module of Gideon is designed to generate a ranked differential diagnosis list for any Infectious Diseases scenario. In recent weeks, we’ve been running simulations of Ebola. The following link will access a Power Point “show” demonstrating one such scenario. Ebola case (Powerpoint)

GIDEON helped save a life with a correct differential diagnosis

In 2005 an agricultural expert from Israel went for 6 days to India to participate in a farming project. He returned to Israel, and the following morning developed fever, headache, vomiting and muscle pain.

Read the latest case of the month, Agriculture Expert in India, about how GIDEON helped save this person’s life.

Pre-travel feature enhances GIDEON for Travel Medicine

Infectious Diseases – Travel


Traditionally GIDEON has been used by Travel Medicine practitioners, who have loved the detailed country information for the various diseases affecting travelers. Their main suggestion was to add more pre-travel information that could be provided to travelers at consultations. We’re happy to announce that we listened and have now launched a new Travel tab in the Infectious Diseases module.

The left side of the Travel section includes the general Region of travel in the upper box, and specific countries in the lower box:

Selecting a specific country lists relevant information in the right-hand column of the Travel section.   The general pre-travel information is provided by region and is divided into Professional, Traveler, and Diseases sections:

The Professional tab is for health practitioners and is based on content from the CDC Yellow book. Links are provided directly to relevant disease information in GIDEON:

The Traveler tab is traveler friendly content from the CDC Traveler’s health destination guide. Links are provided to additional information from the CDC:

The Diseases tab displays the list of all the relevant diseases that have additional information for travelers to the selected country. The content is presented briefly as a “mouse over” and can be accessed more thoroughly by linking to actual country note for the specific disease:

As with all the information in GIDEON, you can print and email each section information. This will be very useful to serve your travelers that want a hard copy of the information or a soft copy via email.

“Traveling with GIDEON” is a new case of the month that demonstrates how to use the Travel tab and includes a video.

Diagnosis search

We just launched a great new feature, Diagnosis search. This provides for an alternate method for entering signs, symptoms and country of acquisition. You can just type them, or their synonyms. See the Getting an Itch on Bali case of the month, or watch the video.
Diagnosis Search box

Text search enhanced with case and video

You can search for keywords in GIDEON using the text search feature. Searches case of the month provides some examples, available as a video as well.
Search box

First case scenario

A new feature has been added to diagnosis result to help diagnose “first cases” of a disease which has never before appeared in a given country. This feature was inspired by the WHO.

See “The First Case” Scenario case of the month and watch the video.

Case of the month

We’ve received frequent request for one page examples of how to use GIDEON. “Case of the month” is an area of the website that demonstrates various aspects of GIDEON. Each case includes a PDF document that can be used as a handout.
For example, the case “West Nile Fever” – Staying in Real Time shows how to use GIDEON to keep track of the latest information regarding West Nile Fever globally.
