Ebola Virus Disease New and Emerging Data
Ebola Virus Disease in West Africa
Ebola Virus Disease in West Africa
October 19 2014 (+ 24 cases in Nigeria, Senegal, Mali, USA, Spain)
Ebola Virus Disease: Current Case Count
This is the First
Ebola Virus Outbreak in West Africa.
The Worst
Ebola Outbreak in
History.
So far, by an Order of
Magnitude.
WHO acknowledges the tremendous efforts of all those involved in
the Ebola Response and in Patient care

Projections
• Capacity for clinical care is minimal and all on-the-ground are overwhelmed with need to perform immediate outbreak care*
• No pre-existing studies and trials truly “on-the-shelf”
• Virtually no existing research culture in healthcare system
• Substantial community and organizational resistance to ‘research’
• Limited capacity to provide a baseline standard of care to a ‘control’ group
• Challenging data collection when nothing can leave the facility
• Substantial regulatory approval delays at many levels
• Delay in truly getting funding to the most promising initiatives
• A disproportionate focus on magic bullets vs. improving the standard of care
Research Challenges
Potential Ways Forward
If we wait for an outbreak or epidemic to start planning, initiating research, we will almost always fail to improve care during the outbreak and for the future We must have somewhat generalizable, flexible observational studies, with paper and electronic case report forms, ready and ethics approved BEFORE These CRFs should be “tiered” and be the platform upon which biological sampling and interventions are tested
• Tier 0: 1-page minimal CRF with descriptors and outcomes • Tier 1: Traditional observational study with characteristics, severity of
illness, course of care, treatments, available labs, outcomes • Tier 2: Biological sampling studies • Tier 3: Intervention Evaluation, open or randomized
There must be funds / a virtual fund-in-waiting to get this work done
