Ebola: Background and General Information


Certainly by now, many of you are probably aware of the ongoing Ebola virus outbreak occurring in western Africa.  Due to the severity and highly infectious nature of this particular strain of the virus in combination with other factors including the culture of the native peoples and poor economics, the diagnosis, treatment, and overall control of this current outbreak are proving to be extremely difficult.  I thought for this post I would share some information about Ebola including what type of methods are utilized in the diagnosis and treatment of this disease.

Ebola is a virus that, along with other closely related pathogens, causes viral hemorrhagic fever; which can be described as uncontrolled bleeding that when combined with vomiting and diarrhea, leads to extreme dehydration and anemia.1  Symptoms of this disease range from less obvious, nonspecific signs including nausea, fever, and rash to more severe manifestations such as bleeding both internally and externally.1  Ultimately, the extreme dehydration and low blood pressure brought on by these more severe symptoms are what typically result in the high mortality rate of this disease.1

Diagnosis of the Ebola virus can be problematic, which aids in the spread of the disease.  Usually, other pathogens that cause similar symptoms are suspected which impedes and compromises the proper isolation and treatment of infected individuals, and also allows for others to become infected due to exposure to body fluids containing the pathogen, thus spreading the disease exponentially.1  Typically, only in situations where the virus is suspected are the proper precautions and confirmation tests conducted in an adequate amount of time.1  These include tests which detect antibodies developed by the patient in response to the virus, tests which look for antigens associated with the virus, molecular testing which identifies known nucleic acid sequences that are present in the pathogen, and viral isolation.1

Treatment of the Ebola virus is currently limited to treating the side effects of the virus through fluids and blood transfusions in order to restore the patient’s electrolyte levels and blood pressure until the virus has ran its course.1

Hopefully in the near future a more efficient treatment method or vaccine may be developed to aid in these ongoing outbreaks, which seem to pop up every few years and devastate many people.

For further information about this disease as well as up to date news about the current outbreak, check out the CDC website.  I have provided a link below in the works cited section for those of you who are interested.
