  19. the resistance that a person has against disease; it may be natural or acquired
  20. short-duration immunity either naturally attained by transplacental transfer from the mother or artificially acquired by inoculation of specific protective antibodies
    passive immunity
  21. immunity either naturally attained by infection, with or without clinical manifestations, or artificially acquired by inoculation of the afent in a killed modified, or variant form; in response, the body produces its own antibodies; usually lasts for years
    active immunity
  22. the time interval between the initial contact with an infectious agent and the appearance of the first clinical sign or symptom of the disease.
    incubation period
  23. a state caused by the invasion, development, or multiplication of an infectious agent into the body
  24. first time; no preexisting antibodies
    primary infection
  25. persistent infection following a primary infection in which the causative agent remains inactive within certain cells
    latent infection
  26. symptomatic reactivation of a latent infection
    recurrent infection
  27. organism capable of producing an infection
    infectious agent
  28. yellowness of skin, sclerae, mucous membranes, and excretions due to hyperbilirubinemia and deposition of bile pigments. aslo called icterus
  29. the microscopic living organisms of a region
  30. widespread epidemic usually affecting the population of an extensive region, several countries, or intravenous
  31. injection by a route other than the alimentary tract, suh as subcutaneous, intramuscular, or intravenous
  32. inflammation of the parotid gland
  33. a virus, mocroorganism, or other substance that causes disease
  34. capable of causing disease only when the host's resistane is lowered
    opportunistic pathogen
  35. by way of, or through, the skin
  36. by way of, or through, a mucous membrane.
  37. protein particle lacking nucleic acid that has been implicated as the cause of certain neruodegenerative diseases; an example is Creutzfeldt-Jacob disease.
  38. early or premonitory symptom
  39. process by which viruses reproduce and multiply
  40. virus with RNA as its core genetic material; requires the enzyme reverse transcriptase to convert its RNA to proviral DNA
  41. the identification of a disease by serum markers of that specific condition
    serologic diagnosis
  42. after exposure to the etiologc agent of a disease, the blood changes from negative (seronegative) to positive (seropositive) for the serum marker for that disease; the time interval for conversion is specific for each disease
  43. a spcific finding (such as antibody or antigen) by laboratory blood analysis that identifies an existing disease state.
    serum marker
  44. presence of virus in body secretions, in excretions, or in body surface lesions with potential for transmission.
    shedding (viral)
  45. an approach to infection control to protect DHCP and patients from pathogens that can be spread by blood or any other bdy fluid, secretion, or excretion (except sweat), regardless of whether they contain blood.
    standard precautions
  46. sexually transmitted disease
  47. continuing scrutiny of all aspects of occurrence and spread of a diseae that are pertinent to effective control
    surveillance (of disease)
  48. host not possesing resistance against an infectious agent
    susceptible host
  49. passage of an infectious afent from one individual to another
    transmission (horizontal)
  50. passage of an infectious agent from one generation to another by breast milk or across the placenta
    vertical transmission
  51. an approach to infection control in which all human blood and certain human bodted as if known to be infectious for HIV, HBV, and other blood-borne pathogens
    universal precautions
  52. a carrier that transfers an infectious microorganism from one host to another
  53. an arthropod, insect, or other living carrier in whose body the infecting organism multiplies before becoming infective to the recipient
    biologic vector
  54. a substanc or object that serves as an intermediate means by which an infectious agent is transported and introduced into a susceptible host through a suitable portal of entry
  55. complete virus particle made up of the nucleoid (the genetic material) and capsid (the shell of protein that protects the nucleoid).
  56. the degree of pathogenicity or disease-evoking power of an infectious agent.
  57. a subcellular genetic entity capable of gaining entrance into a limited range of living cells and capable of replication only within such cells; it contains either DNA or RNA, but not both.
  58. the time between exposure resulting in infection and the presence of detectable serum antibody; antibody test is negative but infectious agent is transmissible during the window period.
