Show Answers:

  1. What is the incubation stage and the incubation period?
    is the time from the first exposure to the pathogen to the time symptoms become apparents

    length of incubation period varies considerably for some microorganisms
  2. What does the incubation time depend on?
    health of the host

    virulence of the microb

    generation of time of the pathogen
