Expert Solution

Step 1 SARS-CoV-2 is a single stranded positive sense RNA (ribonucleic acid) virus.

It is an enveloped virus and the envelope is coated with spike proteins, envelope and membrane proteins. S proteins mediate the binding and entry of the virus into the host cell via the receptor ACE2 (angiotensin converting enzyme 2). The receptors are mainly found in the human respiratory tract epithelium. The transmission of the virus is primarily by infected respiratory droplets.

It binds to the ACE2 receptor. The replication and the release of the virus into the lungs causes fever, myalgia, headache. In severe infection leading to the death of the patient, lungs shows alveolar damage, mononuclear infiltrates, and desquamation.
