1. Global Overview: Epidemiological Data That Speaks Volumes<\/strong><\/h5>\nThe lungs are the most commonly targeted organs in invasive fungal infections. According to the Global Burden of Disease (GBD) 2021<\/strong> study, an estimated 5.62 million pulmonary fungal infection cases<\/strong> occur annually, resulting in approximately 45,542 deaths per year<\/strong>, with an age-standardized mortality rate of 0.56 per 100,000 population<\/strong>. By 2044, deaths caused by invasive pulmonary fungal infections (PFIs) are projected to exceed 87,000 cases<\/strong>, indicating a trend that cannot be overlooked.
