Question 3

Describe the five stages of disease progression for a typical acute infectious disease.

Accepted Answer

Infection occurs when the infectious agent invades and propagates in the host. The incubation period occurs just after infection and includes the time when the pathogen has yet to cause disease as well as cause the first (weak) symptoms. The acute period occurs when the disease symptoms are at its peak, and once the symptoms begin to subside it is considered the decline period. Convalescence is the last period of disease progression where the individual regains strength and returns to normal health.
