Ebola pwpnt(2) Ebola pwpnt(2) Presentation Transcript

  • Ebola Hemorrhagic Fever Fatal 90% of the time
  • Ebola Virus
    • Ebola Hemorrhagic Fever is an almost always fatal disease
    • Caused by an infection with the Ebola virus
    • Transmitted zoonticly, or animal borne.
    • The virus is spread through acute infections and has no carrier state
    • Communicable through an infected person by coming in contact with secretions, needles used by the infected, and breathing the same air.
  • Who Does It Affect?
    • Humans and nonhuman primates like monkeys, gorillas, and chimpanzees
  • Origin
    • Most outbreaks were seen in Africa
    • Ebola was actually named after a river in the Democratic Republic of the Congo in Africa
    • One of the two members of a family of RNA viruses called the Foloviridae.
  • Five Sub-Types
    • Ebola-Zaire
    • Ebola-Sudan
    • Ebola-Ivory Coast
    • Ebola-Bundibugyo
    • all have caused disease in humans
    • Ebola-Reston
    • found in nonhuman primates but not in humans.
  • Signs & Symptoms
    • The incubation period 2-22 days
    • Lesser ailments include fever, joint and muscle aches, sore throat, weakness, diarrhea, vomiting, rash, and hiccups.
    • More extreme symptoms include severe stomach pain, internal and external bleeding, limited kidney and liver function, chest pain, shock, blindness, and vomiting blood.
  • Why Is Ebola So Deadly?
    • The virus is usually detected after some of the more severe signs and symptoms begin to appear
    • 90% of the time a fatal disease
    • Ebola is often mistaken for malaria, typhoid fever, dysentery, influenza, or bacterial infections
    • Appears in sporadic outbreaks most times in a health care setting – amplification
    • Chronic-only 10% of the people who get it survive
    • No information or records of a person who has caught Ebola twice; probably b.c. most victims die from getting it once
  • How It Works
    • The virus interferes with the endothelial cells lining the interior surface of blood vessels
    • As the virus attacks the cells that make up the blood vessel walls, the walls become damaged and destroyed
    • The platelets are unable to coagulate (clot) resulting in
    • Profuse, and often fatal, internal bleeding
  • Cures or Vaccines?
    • Prevention: stay away from infected persons or animals
    • Most people get sick from taking care of infected family or friends and not using proper preventive measures i.e. wearing gloves and/or a mask
    • There is no vaccine or known course of treatment for Ebola
    • Patients can undergo supportive therapy and treatment for some symptoms
    • Scientists are still researching vaccines, cures, and more effective treatments
    • Most people die from the massive blood loss, not necessarily from the disease
  •
