SARS-CoV-2 was first identified in Wuhan, China in late 2019 and has since spread to over 200 countries. It belongs to the coronavirus family and causes the disease COVID-19. The virus enters cells through the ACE2 receptor and replicates its RNA and proteins before being released to infect other cells. Potential treatment strategies include using existing antiviral drugs, developing specific drugs that target the virus genome or proteins, and enhancing immune responses. Ongoing research focuses on antibody development, diagnostic assays, vaccines, and other medical countermeasures to treat and prevent the spread of SARS-CoV-2.

SARS-CoV-2 Treatment Strategies
7. 3-1. Target to the Host
• Enhance immune response - such as the
release of interferon.
• Block the signal pathways
required for virus replication.
• Target viral and cell surface receptor
proteins (ACE2).
Object of Specific Drugs
8. • Prevent viral RNA synthesis - target
to the genetic material of the virus.
• Inhibit virus replication - target to
key enzymes of the virus.
• Block the virus’s binding to human
cell receptors or inhibiting the
virus’self-assembly process - target
to the structural proteins of the virus.
