acute phase
Illness at peak
The acute phase is the initial, intense period of a disease or condition, when symptoms are most severe and the body mounts its strongest response.
It contrasts with chronic phases, where conditions persist at lower intensity over longer periods: The acute phase of the infection lasted about a week.
In immunology, the acute phase response involves rapid changes in blood proteins following injury or infection.
- feverElevated body temperature
- complement proteinsPlasma pathogen-destruction system
- alpha-1 antitrypsinProtective blood protein
- ferritinIron-storing blood protein
- fibrinogenPlasma protein for coagulation
