Coronavirus disease 2019<unk> -19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus named for the similarity of its symptoms to those caused by the severe acute respiratory syndrome. Unlike SARS-CoV, the transmission of<unk> -19 takes place during the prodromal period when those infected are mildly ill and are carrying on with their usual activities. This contributes to the spread of infection. The main pathogenesis of<unk> -19 is severe pneumonia, RNAemia, combined with the incidence of ground-glass opacities, and acute cardiac injury. Person-to-person transmission occurs primarily via direct contact or through droplets spread by coughing or sneezing from an infected individual.
