Ebola: The Right Approaches to Curbing A Fatal Disease Epidemic

Ebola Virus Disease

An outbreak of a disease that turns into an epidemic is a cause for concern for the
entire world. With the ‘international’ becoming ‘global’, anything and everything that
happens in one part of the world creates a domino effect in the rest of it. This stands
true for all instances of global pandemics and epidemics.

In the recent past, SARS, Bird Flu, Swine flu, and more recently Ebola have all been
epidemics whose impact was felt around the globe. For example, during the bird flu
pandemic, poultry and food businesses all around the world were adversely affected.
People started culling birds mercilessly, stopped buying bird meat, governments
prohibited the movement of poultry products in global trade markets etc… This
resulted in losses to people, families, businesses and global trade. A pandemic of such
scale also meant pressure on governments and national healthcare institutions.

When the first outbreak of Ebola occurred, the World Health Organisation declared it as an international health emergency. Scientists and researchers from all over the world put up a united front to find a vaccine for the Ebola virus. Although the virus was contained with effective disease control interventions, a vaccine that could act as an antidote could
not be formulated.

Ebola: A Second Time

In August 2018, following the death of a woman in the North Kivu province of the
Democratic Republic of the Congo (DRC), the country’s Health Ministry declared an
official outbreak of the Ebola virus disease (EVD). It was inferred that the epicenter
was from the outskirts of the city of Beni, DRC.

The virus spread rapidly, to the extent that on July 17, 2019, the World Health Organization (WHO) declared an international health emergency for Ebola in the DRC.
As of September 2019, the recent outbreak of Ebola has claimed the lives of over 3,000
people in the DRC and is said to be the second-largest Ebola outbreak in history.

The first outbreak of Ebola in the West African region was characterized by a very high
number of deaths resulting from this disease — over 11,000. The initial attempts to
contain the epidemic were difficult as the international community and health
officials didn’t have any concrete information about this new and deadly virus.

However, with lessons learned during the last outbreak, the international community
including the WHO is going all out to fight the disease.

What is Ebola and Ebola Virus Disease (EVD)

Ebola is a virus that takes its name from the Ebola river. One of the earliest cases of
Ebola outbreak originated from the area around the Ebola river. The Ebola Virus
Disease (EVD), previously known as Ebola Haemorrhagic Fever is a rare but severe disease. It often results in death for humans. According to the WHO, “the average EVD
case fatality rate is around 50%. Case fatality rates have varied from 25% to 90% in
past outbreaks.”

Transmission of EVD

The Ebola virus is transmitted to people from wild animals and spreads from human-
to-human transmission. Research reveals that the Ebola virus breeds in fruit bats and
primates such as gorillas, chimpanzees etc… If these infected animals come into
contact with human beings, then human-to-human transmission of the disease can
spread very quickly in a large population of human beings. Furthermore, the
symptoms of Ebola may not show immediately and, until a person starts showing
symptoms of Ebola, they cannot infect another person.

According to the Centers for Disease Control and Prevention (CDC), Ebola can be
contracted through broken skin or mucous membranes in the eyes, nose, or mouth
through the transmission of bodily fluids such as blood, semen, vaginal fluids and
even breast milk. The Ebola virus can also spread through syringes and needles used
by an infected person or a person who has died from Ebola. Thus the spread of Ebola in
human populations takes place very easily and quickly. Therefore, Ebola is a
dangerous disease and one must take extra precautions and be very alert to symptoms.

Risks from External Carriers of the Disease

Pets such as dogs and cats have been known to carry the virus but not infect human
beings. However, domestic animals like pigs have found to be carriers of the disease
and infectors as well. Usually, Ebola cannot spread through food. However, persons
handling raw wild meat are said to be at risk of contracting the disease from these
animals, through their blood for example. Nevertheless, strict care is advised.
This is why it is crucial to take precautions with respect to Ebola.

Curbing the Spread of Ebola Virus Disease

Unfortunately, not all persons affected with Ebola can be cured as there is no vaccine
that can successfully eliminate the virus. However, all hope is not lost. With the right
preventive measures, Ebola can be controlled and persons with Ebola in the early
stages can be saved.

Therefore it is critical for society to work together to devise solutions to prevent
fatalities resulting from Ebola. The best point to start our fight with Ebola is in our
own homes and communities.

Owing to the quick spread of the disease from one person to another, it is mandatory
to ensure the strictest hygiene standards by health workers in hospitals and
caregivers to patients at home. Right from “ case management, infection prevention
and control practices, surveillance and contact tracing, a good laboratory service, safe
and dignified burials, and social mobilization.” (WHO, 2019)

More importantly for persons affected with Ebola, early supportive care by a family
member(s), for example, is strongly advised. The chances of the virus spreading can

significantly decline if symptomatic treatment is offered early on. This includes
adequate rehydration of the patient(s) for example.

Therefore, it is vital that each one of us seeks information about the same from the
right sources. The nearest health post, hospitals, local doctors and websites of global
health organizations like the WHO and CDC are a good starting point. These important
learnings and practices can empower us to save lives. Efforts at the individual and
community level can also reduce the burden on healthcare infrastructures such as
health workers and hospitals. It is also important to note that health workers are at
serious risk of infection while treating Ebola-affected patients. With individual and
community action, we can save the lives of health workers as well.

Curative Treatment For Ebola

At the international level, it is important to note that, vaccines that offer protection
against Ebola as well as different blood, immunological and drug therapies are under
development (WHO, 2019). Although there is no breakthrough in devising a treatment
to fully eradicate the virus, certain vaccines have succeeded in controlling the spread
of Ebola outbreaks in the DRC and Guinea. According to Conern USA, ever since the
second Ebola outbreak in the DRC, almost 220,000 Congolese have received, rVSV-
ZEBOVGP, an Ebola vaccine. The WHO has stated that two Ebola treatments are
currently being administered in the DRC as part of a clinical trial. However, these
vaccines are proving to be successful only when used at the right time. The success
rate is a positive ratio of 9 out of 10 lives being saved.

Conclusion

Ebola is a deadly disease affecting people in hundreds and thousands. Its tendency to
spread very quickly and without warning is what puts each one of us at risk. Therefore
early detection and supportive care are of paramount importance. This increases
chances of survival manifold. Mere reliance on under development vaccines is not the
answer to fighting Ebola.
