Management of Ebola outbreak | Q&A

Management of Ebola outbreak
1. What aspects of this case study exemplify the basic science of public health (e.g., the
population affected, distribution, determinants)?
The outbreak of Ebola in West Africa is one of the drastic endemics in history. Immediate
consideration was done by the Guinea Ministry of Health. According to the report of the
health department, the infection is featured by increased temperature, severe diarrhea, and
vomiting. The population affected was about 59% among 49 persons (Nwabuko, Nwamoh,
& Chikezie, 2018). The distribution of the disease was extended in all the direction First case
was discovered in Sierra Leone on 24 th May which was spread to Liberia, and Guinea.
During the mid of June, the total number of cases identified in all three countries was 528.
The outbreak was first started in the remote part of Guinea which was identified as a
mysterious disease. The determinants are handling ill or dead animals that are infected.
2. Describe how we can use epidemiology to explain and predict the Ebola outbreak.
What kind of questions should we attempt to answer?
According to report of World Health Organisation the outbreak of Ebola in West Africa was
the historical incident. The epidemiological analysis was done according to 26,593 cases
between the periods of March 2014 to may 2015. 11,020 deaths were reported in the month
of May. The increase of the number of fresh cases in three countries was reduced in number
which significantly shows the epidemiological changes of Ebola. When there were no new
cases identified in the month of June 2015 and the World Health Organisation declared that
the disease is eradicated. On comparing the peak season of Ebola outbreak, new cases was
decreased to 92.13% in Guinea (Allgaier, & Svalastog, 2015). The questions that can be
answered are the causes for the outbreak, epidemiological data, when the first case was
discovered and the number of cases identified and when the outbreak started.
3. Describe the clinical versus epidemiologic descriptions of the Ebola outbreak.

The clinical descriptions of Ebola are sudden increase of body temperature, fatigue and
tiredness, vomiting, diarrhoea, sore throat, skin rashes, dysfunction of kidney and liver.
Epidemiological description of Ebola virus disease was continually spread throughout the
West Africa. The number of confirmed cases increased after the discovery of first case. The
mortality rate was increased up to 50% (Kangbai et al. 2019).
4. Surveillance system for an Ebola outbreak. How should the findings be disseminated
and to what stakeholders?
According to the guidelines of World Health Organisation the surveillance system for Ebola
outbreak was implemented in the ensure quality patient care and to break the chain of
transmission. A medical team travelled to Guinea and Liberia as the result of outbreak of
Ebola (Wiwanitkit et al. 2015). The ministry of health controlled the outbreak through
collecting the information regarding the cases reported, interviewed the patients and family,
tracing the people who contacted with cases with Ebola, and recorded the data into the
centralised database. The dissemination of the Ebola virus outbreak occurs by contact with
the infected body fluids of the diseases animals or humans. The spread of virus occurs rapidly
when the normal people attend the funeral ceremony of the deceased and take part in cleaning
and washing the dead body. World Health Organisation, Ministry of Health, and CDC
response teams are the stake holders.
5. What type of control measures should be implemented and when?
The control measures can reduce the number of people get affected and the chain of infection
will be broken. The health care workers need to implement universal precautions which
include use of gloves, mask, gown, and goggles to prevent communicating the infection to
non-infected person (Pandey et al. 2014). Public needs to avoid the contact with the infected
person, infected body fluids, and avoid exposure to contaminated objects. Direct exposure

without protective equipment has to be avoided. The control measure need to be started when
there is the possibility of exposure to the Ebola infected person.
6. Are there other data that should be collected, and how should they be presented?
The data is the vital tool which aids in planning the management and control of outbreak. The
data that is essential in managing the Ebola outbreak are the severity rate, transmissibility,
transmission heterogeneities, and effectiveness of the management strategies, exposure data,
and data of affected population (Cori et al. 2017). The collected data need to be digitalized
primarily. The data has to analyse in various aspect for the present management and
prevention of Ebola outbreak in future. Electronic and digital inputs in maintain the data can
prevent confusion and meets the need. Manual presentation of data has to be avoided as it
may lead to errors.
