Sticky Virus Dynamics

The current coronavirus is part of a larger family that includes viruses causing the common cold and SARS. Its spike protein binds more tightly to human cells than the original SARS virus, making it easier to transmit and requiring a lower infectious dose. Virologists have humorously dubbed the original SARS as "SARS classic" to avoid confusion, highlighting the stark differences between the two viruses amidst the ongoing pandemic.
