A novel human coronavirus—now named severe acute respiratory syndrome coronavirus  (SARS-CoV-2)—emerged from Wuhan, China, in late 2019 and is causing a pandemic. Coronaviruses are enveloped RNA viruses that affect animals and humans. Coronavirus particles range from 60 to 140 nanometers (0.06 to 0.14 micrometers), with an average of 0.125 micron, and have distinctive spikes of nine to 12 nanometers that give the appearance of “coronas” around the sun (figure 1). Cell death is observed 96 hours after inoculation on surface layers of human airway epithelial cells.hurt.
