Fungal pneumonia is a type of pneumonia with a relatively long course, and the antifungal drugs chosen clinically need to be used for about 4 weeks, and if the condition is relatively severe the treatment time needs to be extended and the course of treatment needs to reach about 2 months to be complete. In particular, for patients with underlying diseases such as tuberculosis, diabetes, AIDS, and tumors, it is necessary to monitor the condition of fungal pneumonia at all times to prevent the patient’s immunity from declining and allowing the fungus to invade and cause a recurrence.
