  1. 1. Submitted by: Susan Henry Keith Noble
  2. 2. Program Goals  Educate first responders on the following:  Background information on Viral Hemorrhagic Fever (VHF)  Recognition of signs and symptoms of VHF  Treatment of patients with S/S of VHF  Transport of patients with VHF  Proper personal protection equipment (PPE) guidelines  Notification guidelines
  3. 3. Program Initiatives  Focus on the recognition, treatment, and transport of suspects VHF patients  Deliver training via an online format  Simple online test  Printable easy to read chart
  4. 4. Viral Hemorrhagic Fever (VHF)  A family of viruses causing severe multisystem syndrome  Damages the vascular system  Prevents self regulation ability  Can cause mild conditions or life threatening conditions
  5. 5.  Zoonotic  A disease of animals that may be transmitted to man under natural conditions  Category A agent  Easily transmitted from human to human  High mortality rate  Require special action from public health agenices
  6. 6. Four Types of VHF  Arenaviruses:  Lassa & Latin American Fever  Carried by rats and mice  Transmitted by feces and urine  Bunyaviruses:  Crimean-Congo & Rift Valley  Transmitted though a arthropod vector  Filoviruses:  Ebola & Marburg  Host of virus is unknown, possible bats  Hemorrhagic Flaviviruses:  Yellow & Dengue  Arthropod vector
  7. 7. Recognition is the key
  8. 8. Signs and Symptoms  Minor Signs and Symptoms  Travel history  Fever  Fatigue, weakness  Dizziness  Muscle aches  Headache  Sore throat  Severe Signs and Symptoms  Travel history  Petechia (bleeding under the skin)  Bleeding from internal organs  Signs of shock  Bleeding from external orifices  Nervous system malfunction  Coma, AMS, SZ
  9. 9. Petechia
  10. 10. Possible Travel History
  11. 11. Modes of Transmission  Animal to Human  Contact with  Urine  Feces  Saliva  Other body fluids  Bites  Human to Human  Contact with body fluid  Contact with contaminated surfaces  Up to 3 weeks  No agreement as far as airborne transmission  Shown in monkeys, but not humans
  12. 12. Protective Measures  Double Gloves  Gowns  Masks  Shoe Covers  Eye wear  N95  Also place on patient
  13. 13. N95 Mask
  14. 14. Decontamination  After exposure  Limit exposure with proper PPE  Wash with soap and water  Irrigate exposed mucous membranes  Non exposure  Disposable equipment discarded  Non-disposable autoclaved  Interior of ambulance needs to be disinfected  Disinfection EMS clothing and footwear
  15. 15. Protocol  Proper PPE  Immediately notify supervisor if you suspect VHF – isolate location if possible  Coordinate transport & reception at hospital prior to leaving scene  Hospital needs to be secure  Able to handle isolates patients  Supervisor to contact local and state public health departments
  16. 16. Treatment  Treatment is normally supportive in care  Fever control  Electrolyte control  Fluid replacement  Blood pressure control  Fluid replacement  Pain management
  17. 17. Post Incident Actions  No current post exposure prophylaxis  A fever of over 101F will trigger isolation and treatment  Will be isolated at home or hospital  Supportive treatment as needed  Information will be provided on how to protect family
  18. 18. Common Types of VHF Signs and Symptoms PPE Required Treatment Transport Consideration s Notes Ebola Hemorrhagic Fever Rapid onset of fever, headache, joint pain, weakness, diarrhea, vomiting, and abdominal pain, rash, red eyes, internal and external bleeding may be present Spread by direct contact and blood Standard PPE Outer gown Rubber boots HEPA Filter Mask Eye Protection Class C Haz-Mat suit No standard treatment Supportive in nature Fluids and O2 Isolation Proper PPE Often Fatal Filoviridae Virus Obtained from infected non-human primates Lassa Fever Nonspecific S/S. May include fever, chest pain, back pain, N/V/D, hearing loss, tremors Spread by direct contact and contaminated food Standard PPE Gowns, protective eyewear Ribavirin (antiviral drug) Supportive Care Isolation Proper PPE Arenaviridae Virus No S/S in 80% infected Most common in West Africa, Spread from rodents to humans Marburg Hemorrhagic Fever Rapid onset of fever. After 5 days of exposure possible N/V/D, maculpapular rash, weight loss, massive hemorrhage Spread from direct contact and blood Standard PPE Outer gown Rubber boots HEPA Filter Mask Eye Protection Class C Haz-Mat suit No standard treatment Supportive in nature Fluids and O2 Isolation Proper PPE Filoviridae Virus Rare Spread via Marburg Bat Common in mine workers Dengue Fever High fever, headache, severe pain behind eyes, joint pain, muscle and bone pain, rash, and mild bleeding Spread by mosquitoes Limit mosquito opportunities No standard treatment Rest Fluids Isolation Proper PPE Protect from mosquitoes Spread by infected mosquitoes Yellow Fever S/S after 3 to 6 days: Fever, chills, headache, back pain, bleeding from GI tract Only spread from infected mosquitoes Standard PPE No standard treatment Supportive in nature Fluids and O2 Isolation Proper PPE Vaccination available Protect from mosquitoes Spread by infected mosquitoes Information obtained from the Centers for Disease Control
