Incubation Period

The incubation period is the time between a pathogen entering the body and the first symptoms appearing.
Chickenpox has an incubation period of 14 to 16 days.
The common cold has a 1 to 2 day incubation period.
Influenza has a 1 to 4 day incubation period.
Measles has a 10 to 12 day incubation period.
Mumps has a 16 to 18 day incubation period.
Ebola has a 2 to 21 day incubation period.

Prodromal Stage

The prodromal stage is the time from the start of nonspecific symptoms (like malaise, low-grade fever, fatigue) to the appearance of more specific symptoms.
Microorganisms multiply during this stage.
Patients can spread the disease to others during this time.
Herpes simplex begins with itching and tingling before the lesion appears.

Illness Stage

The illness stage is when the patient shows symptoms specific to the infection.
Strep throat causes a sore throat, pain, and swelling.
Mumps causes a high fever and parotid gland swelling.

Convalescence

The convalescence stage is when the acute symptoms of the infection disappear.
Recovery time depends on the severity of the infection and the person's immune system.
Recovery can range from a few days to months.
