need help? review these concept resources.

Explanation:

The incubation period is the time between exposure to a pathogen and the appearance of symptoms. During this period, the pathogen multiplies in the body. Symptoms (like fever, cough etc.) are not present during incubation (that's the prodromal or illness period). Also, different pathogens have different incubation periods (e.g., common cold has a shorter incubation period compared to rabies).

Answer:

pathogen multiplication
