Blood count 16 low fever, if due to infection can be actively anti-infection (such as the use of ribavirin, cefadroxil, etc.); if due to hematologic diseases, need to actively chemotherapy (such as imatinib, etc.). General blood 16 refers to the blood white blood cell count 16 × 10 ^ 9 / L, normal adult white blood cell count (4.0 ~ 10.0) × 10 ^ 9 / L, white blood cell count 16 × 10 ^ 9 / L suggests that the blood white blood cells are elevated, white blood cell count 16 × 10 ^ 9 / L causes of low fever are as follows. 1. caused by infection: for example, bacterial infection, viral infection, tuberculosis mycobacteria infection and other systemic or local infections, the body’s white blood cells will rise mildly, and the body temperature will also rise. Generally speaking, the temperature and white blood cells will be reduced to normal after taking antitoxic treatment (actively controlling the infection, such as antibiotic cephalosporin for bacterial infection, antiviral treatment such as ribavirin or acyclovir for viral infection, and anti-tuberculosis treatment such as isoniazid, rifampicin and pyrazinamide for Mycobacterium tuberculosis). 2. Caused by hematopoietic diseases of the blood system: such as leukemia, chemotherapy (such as imatinib, etoposide, methotrexate, etc.) is needed. The above drugs need to be used under doctor’s supervision. White blood cell count 16 × 10^9 / L low fever ultimately recommended as soon as possible to the local hospital for relevant examinations to identify the cause of the targeted treatment.
