Background Info
Ebola

Ebola is a common name
for a virus family called
Filoviridae


Ebola has caused a
number of serious
outbreaks since its
discovery
The Ebola virus first came to notice in 1976 in outbreaks of
Ebola hemorrhagic fever in Zaire and Sudan.
Sudan.
The outbreak of Ebola in Zaire had one of highest fatality
rates of any human pathogenic virus.

Size & Structure

Viruses characterized by
long filamentous
morphology with
protein/lipid viral envelope
This virus causes
hemorraghic fever
Ebola virus is a thread like
structure around 288 amino
acids long
Virions are tubular and may
appear as a “ U ”
Virions are usually 80 nm long
Ebola is one of known
viruses that can live
outside a human body
without dying (unlike HIV)

Symptoms


Symptoms varied and
appear suddenly
Initial Symptoms: high
fever, severe headache,
muscle/joint pain,
abdominal pain,
exhaustion/weakness,
sore throat, nauseas, and
dizziness

Symptom progression



Ebola victims
Ebola may progress to much worse symptoms such as:
diarrhea, dark or bloody feces, vomiting blood, and red
eyes due to distension
Much worse symptom is interior bleeding due to a chemical
reaction between the virus and platelets that creates a
chemical that cuts cell sized holes in your capillaries.
Eventually you will die after 5-7 days from ONE
MILLION CUTS due to this chemical created by the
reaction
Transmission


Ebola is transmitted by
direct contact with
infected body fluids, or
mucous membrane
Little evidence evidence
for human-to-human
transmission in any
reported epidemics


The handling of infected
chimps, gorillas, and
forest antelopes (both
dead and alive) can lead
to the infection of
whoever handles them
Ebola is unlikely to spread
worldwide due to its
difficulty by spreading
through air and the
amount of time that virus
can use a living organism
to spread.
Treatment
Includes minimizing invasive
procedures, balancing
electrolytes because patients
are frequently dehydrated,
replacing lost coagulation
factors to help stop bleeding
and to maintain oxygen and
blood levels


Vaccines for Ebola have
been made but are only
for a group of monkeys
Vaccines for humans have
been produced but have
had no success
2
Between 1976 and 1998 more than 30,000 mammals, birds, reptiles,
amphibians, arthropods samples have been taken in Ebola outbreak
regions but no Ebola virus was detected

The only human treatment for Ebola is taking antibodies
from a human immune to the Ebola virus and injecting the
antibodies into their blood stream (risking the transmission
of other diseases) so it can help fight the virus. It has
proven to be 90% effective yet Western doctors have
disapproved of this treatment for the Ebola virus

Conclusion

To sum it up Ebola virus has been deadly to those
threatened by the virus because theirs no cure for Ebola
virus. Many have died in the many outbreaks of the Ebola
virus and only few have survived. It’
It’s transmitted through
mammals and is one of few viruses that can survive
outside a living organism. THE END……
JUST
END……JUST
KIDDING…
KIDDING….YOU ARE GOING TO DIE

During the 1976 and 1979
outbreaks of Ebola, bats
were studied because they
were found in the region
of the outbreak and were
found to contain the Ebola
virus in them
We used




Ebola virus was detected
in gorilla carcasses,
chimps, and duikers in
outbreaks in 2001 and
2003
