For example, the incubation period of chickenpox is 14-16 days.. The time before the symptoms of a viral infection appear is called the incubation period.During this time, viral genomes are replicating and the host is responding, producing cytokines such as interferon that can have global effects, leading to the classical symptoms of an acute infection (e.g., fever, malaise, aches, pains, and nausea).
