Blood fungal infection refers to a series of symptoms such as chills, chills and fever caused by the invasion of fungus from inside the body or from outside under certain conditions. Blood fungal infections are common in cases where the body’s immunity is severely reduced, such as in patients who have been using glucocorticoids for a long time or in leukemia patients after high-dose chemotherapy. Blood fungal infections can easily occur when the immune function of the body is severely impaired. After the occurrence of blood fungal infection, the patient will have a series of symptoms such as chills, chills and high fever. If a blood culture test is done, it is possible to find fungal colony formation and also to find out which drugs are sensitive to the fungus, such as voriconazole, itraconazole, etc. By treating the fungal-sensitive drugs, the fungal infection will be gradually controlled.
