2. INTRODUCTION  Ebola virus disease is a serious, often fatal condition in humans and nonhuman primates. Ebola is one of several viral hemorrhagic fevers, caused by infection with a virus of the Filoviridae family, genus Ebolavirus.

3. BODY  The fatality rates of Ebola vary depending on the strain. For example, Ebola-Zaire can have a fatality rate of up to 90 percent while Ebola-Reston has never caused a fatality in humans.  The infection is transmitted by direct contact with the blood, body fluids, and tissues of infected animals or people. Severely ill patients require intensive supportive care. Ebola virus disease (EVD) is often characterized by the abrupt onset of fever, intense weakness, muscle pain, headache, and sore throat.feverheadachesore throat  Ebola tends to spread quickly through families and friends as they are exposed to infectious secretions when caring for an ill individual. The time interval from infection with Ebola to the onset of symptoms ranges from 2-21 days.

6.  Sierra Leone is facing a worsening Ebola crisis day by day. Whilst it’s neighbours begin to seize control over the vicious and deadly virus, Sierra Leone’s number of Ebola cases continues to spiral higher and higher. Despite the sluggish start to the international response, it is now not the volume of aid that is impeding the progress of counter-Ebola efforts, but the lack of human and infrastructural resources on the ground.  The above shows that the weekly reported Ebola cases in both Guinea and Liberia are declining, and have been since the beginning of September. However, despite these countries’ ability to control the outbreak, the cases in Sierra Leone’s are still rising.  There was gradual decrease survival Ebola virus from year 2014 until 2016 at percentage 28% to 0%.  From year 2014 to 2015 there was increase of 34% on survival of Ebola virus.  Based on bar chart the highest percentage of survival on the country’s of Sierra Leone in years 2015 is 60%.  The lowest percentage of survival Ebola virus on year 2014 with 1%.

7. CONCLUSION  These two charts show an increase and decrease of survival Ebola virus within Africa country. The survival Ebola virus is a serious illness that fatal if untreated. RECOMMENDATION  The Ebola outbreak in west Africa is now over. The risk of catching the infection while travelling to previously affected countries is very small. But if you’re visiting one of these areas, it’s still a good idea to follow a simple precaution to minimize your risk of picking up potentially serious infection.
