Other Concepts Related to Disease CyclesSuccessful Infections => symptomsBefore symptoms:Incubation period = time between inoculation andpenetration and appearance of the disease symptom.The length of the incubation period of differentpathogens/diseases varies with:1. the particular pathogen-host combination2. the stage of development of the host3. the temperature in the environment.Can make disease assessments misleadingIf infections are presymptomatic during scouting.
Latent period = time from infection untilproduction of new inoculum (reproduction).Duration can have a large effect on the rate of theepidemic.Affected by characteristics of the host (stage ofdevelopment, age of tissue, physiological condition),the pathogen,and the environment (temperature, moisture).
