Course of Infection by Stage

A

Incubation Period
Prodromal Stage
Illness stage

41
Q

interval between entrance of pathogen into body and appearance of first symptoms

A

Incubation Period

42
Q

Interval from onset of nonspecific signs and symptoms (malaise, low-grade fever, fatigue) to more specific symptoms. (during this time microorganisms grow and multiply, and patient may be capable of spreading disease to others)

A

Prodromal Stage

Q

Interval when patient manifests signs and symptoms specific to type of infection. for example: strep throat is manifested by SORE THROAT, PAIN, SWELLING.

A

Illness Stage

A

Convalescence

45
Q

body’s Nonspecific Defenses
