The patient show the symptoms of the illness is c.
Based on the image of Figure 13.2, the patient would show the symptoms of influenza during time period c. This is because the graph shows that the number of virions (viruses) in the body peaks during this time period, indicating that the virus is actively replicating and causing the patient to become sick.
The other time periods on the graph represent different stages of the influenza infection:
a: This is the latent period, during which the virus is present in the body but not yet replicating.
b: This is the early incubation period, during which the virus begins to replicate but the patient is not yet symptomatic.
d: This is the late incubation period, during which the virus is replicating rapidly and the patient is starting to experience symptoms.
e: This is the convalescence period, during which the virus is being cleared from the body and the patient is recovering.
Complete question:
