Abstract

Respiratory infections, encompassing a range of bacterial, viral, fungal, and parasitic pathogens, represent a significant global health challenge. These infections can lead to severe outcomes, including chronic respiratory disease, hospitalization, and even death. This article provides a comprehensive review of respiratory infections, focusing on their etiology, pathogenesis, diagnostic approaches, and management strategies. We examine the various pathogens responsible for respiratory infections and their mechanisms of disease. Diagnostic methods, including clinical evaluation, laboratory tests, imaging, and advanced techniques, are discussed in detail to highlight their roles in accurate and timely diagnosis. Treatment options, ranging from antimicrobial therapies to supportive care, are explored to underscore the importance of individualized patient management. Additionally, we address preventive measures such as vaccination and hygiene practices that are crucial for reducing the incidence and spread of respiratory infections. By synthesizing current knowledge and emphasizing evidence-based practices, this review aims to enhance understanding and guide effective strategies for the management and prevention of respiratory infections.
