Exclusive Features of COVID-19: SARS-CoV-2, the causative agent of COVID-19, is transmitted via direct, like coughing or indirect contact. SARS-CoV-2 invades the lung alveolar cells via ACE-2 receptors, wherein it replicates and assembles more virus particles, which then invade neighboring cells. Host immunity surveillance recognize the viral particles and mount an immune response that may be overdriven to cause ARDS, multi-system organ failure and death (Created with BioRender.com).
