1. Corona virus is a microscopic size organism composed of an RNA genome (retrovirus)
2. The virus has protein spikes on its surface that look for specific receptors on the host surface cells that they can bind to and allow them to inject their genome for production of more viruses.
3. The corona virus uses the lyric cycle whereby after injection of its genome into the host cell, it immediately starts to use the cells machinery to replicate and produce more viruses before the host cell bursts open through lysis thus releasing more viruses
