Transcript of EBOLA


Hemorrhagic Fevers Introduction
Four separate virus families: arenavirus, filovirus, bunyavirus, flavivirus.
Usually found in Central Africa.
Ebola Introduction
All 4 families are RNA viruses
Humans are not reservoirs for any of the VHFs.
No cures and very few effective treatments.
Most well known: Ebola (filovirus), Marburg (filovirus), Lassa fever (arenavirus), Rift Valley fever (bunyavirus).
First discovered in 1976 in Democratic Republic of Congo (Zaire).
Highest known pathogenic mortality rate. (>70%)
By: Brian Baker
Outbreaks are sudden and without warning.
No known reservoir- fruit bats are most commonly suspected.
Confirmed Cases: Democratic Republic of Congo, Gabon, Sudan, the Ivory Coast, Uganda, and Republic of Congo.

Ebola-Reston: Infected and killed primates imported from the Philippines, though humans also became infected, they did not become ill.
Outbreak Locations
Early Symptoms
Incubation period: 2-25 days (Mean= 12.7 days).
Early symptoms are nonspecific flu like signs (cough, aches, fever, etc.)
Abrupt onset with eventual point of no return.
Ebola Symptoms
Rash, red eyes, internal; external bleeding, vomiting(sometimes bloody), diarrhea.
External bleeding from orifices only in about 50% of patients
Next slide contains graphic images.
Red Eyes
Subcutaneous Hemorrhaging
Internal/External Hemorrhaging, death
There is no cure for Ebola.
Support therapy consisting:
Balancing fluids, electrolytes
Maintain oxygen, blood pressure
Infection complication treatments
Recent studies from Canadian National Microbiology Lab may have an antibody cocktail that proves to be efficient in aiding recovery.
Bush meat(bats, nonhuman primates, etc.)
Close contact with suspected reservoirs.
Direct Contact:
Organ tissue
Indirect Contact:
Unsanitary Equipment
Lack of Biosafety Level 4 Procedures
Transmission Flowchart
Control Measures
Quarantine patients with Ebola.
Virus particles isolated in reproductive fluids up to 8 weeks after surviving infection- use of STD preventative measures highly recommended for survivors.

Completely sterilize medical equipment.
Usage of Bio-Safety levels 3 or higher.
Ebola is a deadly disease with a small chance of survival.
Little fear in our area because it can only survive in specific regions in Africa.
Although it can be bio-weaponry, it still is not very likely to spread through a population because of high virulence burning itself out.
Research for a cure is a top priority in many first world countries.

Impacts on Lifestyle
While most patients will die from the disease, the ones that survive usually make a full recovery.
The complications if any are minor pains in joints, headaches, or weakness of muscles.
Social problems may result because of fear that one still could infect others after survival.
