Pulmonary fungal infections do not necessarily lead to death; their survival time is related to the specific condition and treatment effect, and cannot be generalized. Pulmonary fungal infections are infectious diseases of the bronchi and lungs caused by fungi. If detected in time, sensitive antifungal drugs, such as amphotericin B, itraconazole, voriconazole, fluconazole, etc., can be used, and after a standardized, full course of treatment, the short time is about 10 days to heal, which will not affect life expectancy. If standardized treatment is not given in time or is incomplete, it can lead to recurrence of pneumonia and prolong the course of the disease. At this time, as the fungus destroys the lung tissue more seriously, it can cause different degrees of fibrosis, calcification, and even abscesses and emphysema of the lungs, causing different degrees of respiratory distress. Finally, it can lead to respiratory failure, causing multi-organ failure leading to death, and this process may be more than 1 year. Therefore, patients should pay attention to more rest during pulmonary fungal infection, pay attention to strengthen nutrition in diet, can consume more high-protein, high-calorie food; actively cooperate with the doctor’s treatment, regular review.
