1 Ebola Hemorrhagic Fever Cory Breaux

2 Ebola Hemorrhagic fever is a disease caused by any of the four virulent strains of the Ebola virus bola_1.jpg

3 Hemorrhagic fevers are diseases causing excessive bleeding, fever, and frequently death cdn.com/content/image/1- s2.0-S X X- gr1.jpg

4 Other Hemorrhagic diseases include yellow fever, Dengue fever and Marburg virus /PHIL_2176_lores.jpg

5 Ebola is a member of the filovirus family, which was first identified in content/14/8/800.long

6 The natural reservoir is unknown, although some species of bats carry the virus rg/writable/rich_text_editor/im ages/hammer_headed_bat.jpg

7 The virus particle, recognized by “Shepherd’s crook” shape, contains a single DNA strand ebola.jpg

8 The first outbreak of Ebola was 1976 in the Democratic Republic of the Congo https://eee.uci.edu/clients/bjbecker/PlaguesandPeop le/week10d.html

9 All outbreaks have been in sub-Saharan Africa, and have been small (<318 cases) b/images/ebola/ebolamap.jpg

10 There have been 3 incidences of exposure in the US, but all have occurred in labs

11 It is transmitted from animals to humans or human to human via bodily fluids cposters/index.htm

12 Thus, healthcare workers are at the greatest risk for acquiring the disease cposters/index.htm

13 Ebola enters the body via mucous membranes, skin abrasions or contaminated needles ml/tileshop_pmc/tileshop_pmc_inline.html?ti tle=Click%20on%20image%20to%20zoom&p= PMC3&id= _DMM000471F1.jpg

14 Earliest symptoms are flu-like Around day 5, characteristic rash appears g/encyclopedia/graphics/ images/en/17160.jpg

15 Infection then becomes systemic, leads to apoptosis, hemorrhage, shock and death

16 There is no treatment available – only containment stops spread

17 No vaccine currently exists, and the disease is difficult to distinguish early in an outbreak rights.org/assets/images/p anzi-ward.jpg

18 Lethality makes research difficult in the lab and speed makes it difficult to assess epidemiologically during outbreaks ons/8/8e/Positive-pressure_biosafety_suit.jpg
