The time between exposure to the pathogen and the onset of clinical symptoms is known as the Incubation period.
The incubation period is the interval between exposure to a pathogenic organism, a chemical, or radiation and the onset of symptoms and indications. It is also referred to as the latent phase or latency period. The incubation period in a typical infectious disease refers to the time it takes for the multiplying organism to reach the threshold required to cause symptoms in the host.
Although the terms latent and latency period can be used interchangeably, there are times when the latent period is distinguished by defining it as the interval between infection and infectiousness. The length of the time varies on the ailment.
Infections like Streptococcus in the throat can be carried by a person even when they don't show any symptoms. The individual may or may not be contagious throughout the incubation period, depending on the disease.
