Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS coronavirus 2 or SARS-CoV-2), a virus closely related to the SARS virus. 

What is The Coronavirus?

Before introducing the SARS-CoV-2, let us understand what is a coronavirus. Coronaviruses are a large family of viruses that can cause respiratory illnesses such as the common cold. Almost everyone gets infected with coronaviruses at least once in their life, but symptoms are typically mild to moderate. Most coronaviruses are not dangerous, but some are. Those that cause Middle East respiratory syndrome (MERS) or severe acute respiratory syndrome (SARS) can be deadly.

As the Figure 1 shows, coronaviruses are viruses that are spherical, have protrusions, and are crown-like. They are collectively referred to as coronaviruses. The virus has a diameter of 75 to 160 nanometers, and the virus genome is a continuous linear single-stranded RNA, and the molecular weight is usually (5.5 to 6.1) x106.

Figure 1. The Typical Structure of Coronavirus

The coronavirus genome encodes a spike protein (S), an envelope protein, a membrane protein, and a nucleoprotein in this order. Among them, spike protein is the most important surface membrane protein of coronavirus.
