Question

Which of the following are characteristics of the stage of infection known as full stage of illness? Select all that apply.

a) Interval b/t pathogen's invasion of body + appearance of symptoms of infection .
b) Presence of specific signs/symptoms indicates full stage of illness.
c) During full stage of illness, organisms are growing + multiplying.
d) Early signs and symptoms of disease are present, but these are often vague and nonspecific.
e) Type of infection determines length of illness + severity of manifestations.

Answer 1

The full stage of illness is characterized by specific, severe symptoms, peak pathogen growth, and variations in the length and severity of illness based on the infection type. It is distinct from the incubation and prodromal periods.

Step-by-step explanation:

Characteristics of the full stage of illness in the context of infectious disease progression include:

• Presence of specific signs/symptoms: This indicates the full stage of illness, where symptoms specific to the disease are most apparent and severe.
• Organisms growing and multiplying: During this stage, the number of pathogens present in the host is at its peak, which corresponds to the heightened severity of symptoms.
• The type of infection determines the length of illness and severity of manifestations: Different pathogens and immune responses influence the duration and intensity of the illness phase.

Options that do not apply to the full stage of illness include:

• Interval between pathogen invasion and appearance of symptoms (incubation period, not full stage of illness).
• Early, vague, and nonspecific signs and symptoms of disease, which are typical of the prodromal period rather than the full stage of illness.
