5 Written questions

5 Matching questions

  1. Viruses with wild mice vectors
  2. Complexities of arboviruses
  3. Mechanism of mosquito transmission
  4. Number of known survivors from rabies
  5. sylvan cycle transmission pattern
  1. a 1
  2. b -Multiple reservoirs
    -mosquitoes to birds, snakes, and rodents then back to mosquitoes
    -animals serve as the winter reservoir
    -humans and horses are dead end, tangential, or incidental hosts
  3. c Sin Nombre
  4. d Mosquito bites its subject injecting a bit of saliva containing the virus into the blood bypassing the skin barrier
  5. e -Mosquito borne viruses must be able to replicate at ambient temperatures in the mosquito as well as that host body temperatures
    -this suggests a very broad host range

5 Multiple choice questions

  1. -This is rare; although West Nile has been transmitted through blood transfusion
  2. chikungunya= Clicking joint disease (found in Africa and the Indian Ocean islands)
  3. -Introduced into the bloodstream by infected insects
    -viral replication in reticuloendothelial system in vascular epithelium
    -secondary viremia can seed target organs
  4. bats
  5. Mosquitoes to humans and back to mosquitoes
    -humans are considered endemic hosts

5 True/False questions

  1. arbovirusEosinophilic cytoplasmic inclusion body found in nerves and characteristic of rabies

          

  2. Viruses with mosquito vectorsSin Nombre

          

  3. Vaccines available-Killed vaccine for humans
    -live attenuated vaccine for animals
    -vaccine recommended for high-risk people (veterinarians, postexposure)
    -rabies immunoglobulin use for postexposure prophylaxis (must must must be started before patient is symptomatic)

          

  4. Other important animal borne virusesIn most cases the endemic host animal is not killed by the virus; however rabies virus is the exception
    -viruses can be highly legal to humans

          

  5. mechanism by which humans contract animal borne virusesIn most cases the endemic host animal is not killed by the virus; however rabies virus is the exception
    -viruses can be highly legal to humans
