What is the cause of high neutrophil percentage and recurrent fever?

A high percentage of neutrophils with recurrent fever indicates an inflammatory infection in the body.
Neutrophils are the main response cells when there is inflammation in the body, and their increase is common in acute bacterial infections such as pneumonia, peritonitis, sepsis, and also myeloid leukemia and its post-surgical effects.
Repeated fevers with a high percentage of neutrophils are most commonly associated with bacterial infections in the body. A significant increase in the number of neutrophils can occur with a bacterial infection, and the release of pyrogens by the bacteria can lead to an increase in body temperature as well.
In addition, if symptoms such as anemia and bleeding are also present one should be alert to the possibility of myeloid leukemia.
If a bacterial infection or leukemia is diagnosed, early and standardized treatment is recommended to minimize the adverse effects of the disease.
