COVID-19: A REVIEW
Keywords:
ARDS., SARS-CoV-2Abstract
The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has emerged as a significant global health crisis, challenging healthcare systems, economies, and societies worldwide. In this comprehensive review, we elucidate the epidemiology, transmission dynamics, clinical manifestations, and pathogenesis of COVID-19. We summarize the current understanding of the virus-host interaction, immune response, and viral pathogenic mechanisms underlying the disease severity spectrum, ranging from asymptomatic infection to severe pneumonia and acute respiratory distress syndrome (ARDS). Furthermore, we discuss diagnostic modalities, therapeutic interventions, vaccine development efforts, and public health strategies implemented to control the spread of the virus. This review aims to provide a holistic perspective on COVID-19, highlighting the urgent need for continued research and global collaboration to mitigate the ongoing pandemic and prepare for future emerging infectious diseases..Keywords: ARDS., SARS-CoV-2
