The infection causes the lungs' air sacs (alveoli) to become inflamed and fill up with fluid or pus. That can make it hard for the oxygen you breathe in to get into your bloodstream [1]. It ranks among the top causes of mortality, with a particularly devastating impact on vulnerable populations, including children and the elderly. Rapid and accurate diagnosis of pneumonia is pivotal for timely intervention and improved patient outcomes. However, the current landscape of pneumonia detection is burdened with challenges, including limited access to healthcare facilities and the shortage of healthcare professionals, especially in underserved regions.
