Explainer: How the coronavirus (SARS-CoV-2) infects human cells

The transcript explains how SARS-CoV-2 infects humans by targeting specific receptors on human cells, particularly in the lungs. The virus uses its spike protein to bind to the ACE2 receptor, facilitating entry into the cell. Once inside, the virus hijacks the cell's machinery to replicate its RNA and produce new viral particles. These new viruses are assembled and released, causing stress and eventual death of the host cell. The process is detailed through studies published in scientific journals, highlighting the virus's impact on cellular structures and functions.
