Answer;
-The third stage fever
Explanation;
-Fever, also referred to as pyrexia and febrile response, involves having a temperature above the normal range (above 37.5 or 38.3 °C)  due to an increase in the body's temperature set-point (36.5–37.5 °C). This increase in set-point temperature triggers increased muscle contractions and causes a feeling of cold.
-The first stage of a fever is marked by headache and body aches, the second stage is marked by the chills, and the  third stage is the flush state. The fourth stage is defervescence.
