The Ebola virus is a severe disease-causing pathogen that poses a huge threat to human health mostly within central Africa. Ebola is considered a Biosafety level 4 (BSL-4) agent; classifying it among the most threatening agents that exist in the world today. Agents within this category pose severe threats to human health and can be fatal due to the lack of treatments and/or available vaccines. There are five known Ebola species within the family <i>Filoviridae</i> and all of the species within the family cause varying degrees of viral hemorrhagic fever illnesses.

Introduction

The Ebola virus is a severe disease-causing pathogen that poses a huge threat to human health mostly within central Africa due to its high mortality4. Ebola is considered a Biosafety level 4 (BSL-4) agent; classifying it among the most threatening pathogens that exist in the world today. Agents within this category pose severe threats to human health and can be fatal due to the lack of treatments and/or available vaccines. There are five known Ebola species within the family Filoviridae and all of the species within the family cause varying degrees of viral hemorrhagic fever illnesses.


Virus Structure


The Ebola virus has an RNA genome that codes for Feldmann, Heinz, Steven Jones, Hans-Joachim Schnittler. "Ebola virus: from discovery to vaccine 3

Include some current research in each topic, with at least one figure showing data.

A map indicating the locations of Ebola outbreaks throughout Africa.





















Possible Treatments


Include some current research in each topic, with at least one figure showing data.

Conclusion

In today's world Ebola is still a huge problem that faces many developing nations within Africa. In 2012 alone there were 5 outbreaks of Hemorrhagic Fevers around the world and 3 of them were due to the Ebola virus.7
