  2. Some people and animals become _ to mosquito bites as a result of repeated exposure to their _
    • hypersensitive
    • bites
  3. Hypersensitivity can occur in people that work in mosquito control or mosquito research through constant _ or _ contact
    with mosquitoes, or even with just their
    _ _
    • dermal
    • respiratory
    • wing scales
  4. Hypersensitive reactions are
    _ reactions
    allergic
  5. _ _ occur when microbial

    individual enter the wound created by a
    mosquito _
    • Secondary infections
    • bite
  6. A secondary infection often occurs as a
    result of _ the mosquito bite
    scratching
  7. _ _ , a viral disease, has virtually disappeared from the USA because of the
    availability of an extremely effective _ , which may provide lifelong
    protection from just a single dose.
    • Yellow fever
    • vaccine
  8. availability of the _ _ vaccine is limited on a worldwide basis and many unvaccinated people live in areas where it is common

    is commonly _.
    • extremely serious
    • treatment
    • fatal
  11. This species is common in urban and suburban areas
    Aedes aegypti
  12. Aedes aegypti larvae occur in
    many kinds of water-filled _ _  such as shallow wells, water urns,
    discarded containers, and tires.
    artificial containers
  13. Dengue, caused by multiple _ of the dengue virus, is transmitted mostly by the _ _ mosquito
    • serotypes
    • Aedes aegypti
  14. _ is considered second in importance only to malaria among mosquito-borne diseases.
    Dengue
  15. The increase in _ _ _ has caused an increase in the number of viral strains causing dengue and the increase in the number of cases of a particularly serious form of the disease called dengue _ _ .
    • global human travel
    • hemorrhagic fever
  16. _ _ _ is most serious in children and is a
    significant cause of mortality
    Dengue hemorrhagic fever
  17. The interactions between mosquito hosts and the _ they transmit are
    highly _
    • pathogens
    • variable
  18. Three basic types of transmission mechanisms are involved _ , _ , _-_
    • propagative
    • developmental
    • propagative-developmental
  19. Propagative transmission : the pathogen _ within the mosquito but does not undergo any changes in _ form
    • multiplies
    • developmental
  20. Developmental transmission : the pathogen undergoes _ changes, but does not _
    • developmental
    • multiply
  21. Propagative-developmental transmission : the pathogen _ and undergoes changes in _ forms
    • multiplies
    • developmental
  22. Transmission of _ is an example of propagative transmission.
    arboviruses
  23. Transmission of arbovirus = the
    _ is taken up by a female mosquito from a viremic host during blood
    feeding, _ many times, and eventually infects the _ _ of the host.
    • virus
    • multiplies
    • salivary glands
  24. Transmission of arbovirus = when the female mosquito takes another _ _ , she may infect a new host by injection of _.
    • blood meal
    • saliva
  25. _ _ are transmitted by mosquitoes by _ transmission.
    • Malarial parasites
    • propagative-developmental
  26. The life cycle of
    the malaria parasite is very _
    complex
  27. The only example of _ transmission by insects is that of _ worms.
    • developmental
    • filarial
  28. In California, the _ _ is
    transmitted via developmental transmission.
    dog heartworm
  29. _ transmission occurs when a female mosquito transmits a pathogen to her eggs prior to oviposition.
    Transovarial
  30. ____  is the ratio of infections
    that do not produce clinical _
    to those that do.
    • Inapparent to apparent disease ratio
    • symptoms
  31. The inapparent to apparent disease ratio is estimated by _ studies, and is affected by things like the degree of _ in a human population.
    • epidemiology
    • immunity
  32. Most _ that result in human diseases have a very _ ratio, usually from 1:100 to 1:1,000
    • arboviruses
    • low
  33. for every person infected with a pathogen only 1 in 100 or 1 in 1,000 developed _ _
    disease symptoms
  34. A feeling of unhealthiness that can be
    expressed by a person.
