A highly lethal virus that causes massive internal
hemorrhaging,1976, named for Ebola River valley in Con
go, where it was first studied.
This virus was originally not in the U.S, but now there
are a few cases of people being diagnosed with it in the
I chose this topic because I feel that it could
possible effect us in the near future.
We should care because the virus has been
brought to the U.S and now it has the possibility
to spread throughout the U.S.
The Ebola River is located in the northern part of the
Democratic Republic of Congo.
Ebola virus is named after this river since this was the
first place where the virus was discovered.
The virus, when it was discovered, had spread to
around 55 villages situated around the banks of the
This river was earlier named Zaire River
during 1971 to 1997 based on the then
government called Zaire.
The Zaire or Congo River, which is now
known as the Ebola River, is in Western
Central Africa and it is the largest river in
Western Central Africa.
There are five different sub-types of Ebola in
the world today.
They are named by the location they were
Tai Forest ebolavirus
It is endemic in the Democratic Republic of the
Congo, Gabon, or the Republic of the Congo.
It has a genomic sequence that differs from the
type virus by less than 30%.
The Zaire strain of the Ebola Virus is the
The species was introduced in 1998 as Sudan
It is endemic in Sudan and Uganda.
It has a genomic sequence different from Ebola
virus by greater than 30%.
BDBV made its first appearance on August 1 of 2007, when
a viral hemorrhagic fever outbreak began in the
Bundibugyo and Kikyo townships of Bundibugyo district in
The outbreak of this type was declared over on February
20, 2008, and then a second outbreak of it started in
August of 2012 in Province Orientale, DRC.
Reston virus is named after Reston, Virginia, US,
where the virus was first discovered.
Despite its status as a level-4 organism, Reston virus
is non-pathogenic to humans, though hazardous to
The Ebola-Reston virus is also the only subtype that
will not cause illness in humans—it only affects
The species was introduced in 1998 as Cote d'Ivoire Ebola
The name was proposed to be changed to Tai Forest
ebolavirus in 2010 and this proposal was immediately
accepted by the ICTV.
It is classified as a Tai Forest species if it has a genomic
sequence different than ebolavirus by 30% and different
than the genomic sequence of Tai Forest virus by less than
Ebola symptoms can take as long as three
weeks to appear. Disease symptoms
Unexplained bleeding or bruising
The virus is known as a “zoonotic” virus because it’s
transmitted to humans from animals.
Since people may handle these infected animals, the
virus can be transmitted via the animal’s blood and
Humans can also transfer the virus to each other.
Once people become infected with Ebola, they
can transmit it to others if people come in
contact with their:
Ebola patients become walking human-to-human virus
transmitters as soon as they begin to show symptoms, and remain
contagious even after death.
Everyone they come in contact with has to be monitored or they
could end up spreading the virus to more people.
To prevent the spread of the disease, they must train
medical staff, test crisis plans, and communicate with the
All that must be accomplished by a public health
workforce diminished by years of budget cuts.
City, county, and state health departments employ almost
60,000 fewer people than they did in 2008, a drop of
The decline is a consequence of the recession, which cut tax revenue
to state and local governments, and the drive for austerity in
Congress, which has led to lower federal spending on health
In 2007 the two federal programs that help local officials plan for
public health emergencies—Public Health Emergency Preparedness
grants and the Hospital Preparedness Program—gave states and cities
$1.3 billion, according to the National Association of County and City
Health Officials. For the budget year that began on Oct. 1, that
shrank to $800 million.
The Ebola virus outbreak that’s ravaging West Africa
probably started with a single infected person, a new
genetic analysis shows.
This West African variant can be traced genetically to
a single introduction, perhaps a person infected by a
bat, researchers report in the journal Science.
In Sierra Leone, it started with a traditional healer,
says virologist Robert Garry of Tulane University, one
of the researchers on the report. The healer treated
patients from across the border in Guinea, where an
outbreak of Ebola had started in February. Her
patients flocked to her funeral, and 14 became
infected as they prepared and buried the healer’s
body, Garry said.
The Ebola virus does not have a cure or vaccine at this time.
Instead, measures are taken to keep the person as comfortable
Supportive care measures include:
Giving medications to maintain blood pressure.
Managing electrolyte balances.
Providing extra oxygen, if needed.
Providing intravenous fluids to prevent dehydration.
Treating co-existing infections and preventing other infections from
When it is known that someone has come in contact
with another person, or that a person has the Ebola
Virus, safety measures are greatly taken.
They isolate this person and closely monitor them
keeping them out of contact with anyone else for a
certain period of time.
Ebola is a rare but deadly virus that causes bleeding
inside of and outside the body.
As the virus spreads through the body, it damages the
immune system and organs.
Ultimately, it causes levels of blood-clotting cells to
drop. This leads to severe, uncontrollable bleeding.
Losing about a fifth or more of the normal amount of
blood in your body causes hypovolemic shock.
Hypovolemic shock is an emergency condition in
which severe blood and fluid loss make the heart
unable to pump enough blood to the body. This type
of shock can cause many organs to stop working.
