• Description: SARS‑CoV‑2 is a kind of coronavirus which full name is severe acute respiratory syndrome coronavirus 2. SARS‑CoV‑2 is contagious that causes the respiratory diseases and lung diseases which make difficulty breathing. SARS‑CoV‑2 do the spillover event in 2019 because it has genetic diversity. SARS-CoV-2 is composed by four subunits (spike, envelope, membrane and nucleocapsid proteins). Its RNA genome is encapsulated with nucleocapsid protein. The viral envelope is comprised of spike, envelope and membrane protein. SARS‑CoV‑2 has high affinity to ACE2, which is highly expression in intestines, kidney, and heart.
