The SARS-CoV2 is a novel coronavirus identified as the cause of the coronavirus disease 2019 (COVID-19) pandemic that began in Wuhan, China in 2019. SARS-CoV-2 can cause severe diseases such as pneumonia, acute respiratory distress syndrome (ARDS), sepsis, septic shock or multiple organ failure, particularly among the elderly and immunocompromised patients. SARS-CoV-2 virus particles are round, elliptic and often pleomorphic in shape and a diameter of approximately 60–140 nm. The SARS-CoV2 genome encodes four essential structural proteins including the spike (S) glycoprotein, nucleocapsid (N) protein, membrane (M) protein, and the envelope (E) protein, and also several accessory proteins.

The SARS-CoV-2 spike protein is present on the outside of the virus particles and is able to bind to angiotensin-converting enzyme II (ACE2) present on the host cells. The C-terminal receptor binding domain (RBD) of the spike protein binds to the N-terminal peptidase M2 domain of ACE2. This receptor binding results in internalisation of the virus-receptor complex and is therefore the mechanism of entry of SARS-CoV-2 into host cells.
