The period between the initial infection and the onset of signs and symptoms
The incubation period is the initial stage of an infectious disease. During this stage the pathogens are actively dividing and growing in number. The duration of incubation period may vary depending on various factors, such as the immunocompetence of the host and the virulence of the pathogen. The next stage after incubation period is the prodromal stage.
