1. Ebola Hemorrhagic
Fever
Fatal 90% of the time

2. Ebola Virus
 Ebola Hemorrhagic Fever is an
almost always fatal disease
 Caused by an infection with
the Ebola virus
 Transmitted zoonticly, or
animal borne.
 The virus is spread through
acute infections and has no
carrier state
 Communicable through an
infected person by coming in
contact with secretions,
needles used by the infected,
and breathing the same air.

3. Who Does It Affect?
 Humans and
nonhuman primates
like monkeys, gorillas,
and chimpanzees

4. Origin
 Most outbreaks were
seen in Africa
 Ebola was actually
named after a river in
the Democratic
Republic of the Congo
in Africa
 One of the two
members of a family
of RNA viruses called
the Foloviridae.

5. Five Sub-Types
 Ebola-Zaire
 Ebola-Sudan
 Ebola-Ivory Coast
 Ebola-Bundibugyo
all have caused disease in humans
 Ebola-Reston
found in nonhuman primates but not in
humans.

6. Signs & Symptoms
 The incubation period 2-22
days
 Lesser ailments include fever,
joint and muscle aches, sore
throat, weakness, diarrhea,
vomiting, rash, and hiccups.
 More extreme symptoms
include severe stomach pain,
internal and external bleeding,
limited kidney and liver
function, chest pain, shock,
blindness, and vomiting blood.

7. Why Is Ebola So Deadly?
 The virus is usually detected after some of the more
severe signs and symptoms begin to appear
 90% of the time a fatal disease
 Ebola is often mistaken for malaria, typhoid fever,
dysentery, influenza, or bacterial infections
 Appears in sporadic outbreaks most times in a health
care setting – amplification
 Chronic-only 10% of the people who get it survive
 No information or records of a person who has caught
Ebola twice; probably b.c. most victims die from getting
it once

8. How It Works
 The virus interferes with the
endothelial cells lining the
interior surface of blood vessels
 As the virus attacks the cells
that make up the blood vessel
walls, the walls become
damaged and destroyed
 The platelets are unable to
coagulate (clot) resulting in
 Profuse, and often fatal,
internal bleeding

9. Cures or Vaccines?
 Prevention: stay away from infected persons or animals
 Most people get sick from taking care of infected family
or friends and not using proper preventive measures i.e.
wearing gloves and/or a mask
 There is no vaccine or known course of treatment for
Ebola
 Patients can undergo supportive therapy and treatment
for some symptoms
 Scientists are still researching vaccines, cures, and more
effective treatments
 Most people die from the massive blood loss, not
necessarily from the disease
