A
Highly diverse family of enveloped positive-sense ssRNA viruses
3
Q
What’s the main barrier against a jump of a virus from neutral reservoir to a new host
A
It’s represented by the need for the virus to efficiently recognize and exploit the cellular receptor in the new species
4
Q
Who helps virus to get in
A
Angiotensin-converting enzyme 2 and transmembrane protease serine 2
5
Q
What does substitution rate measures
A
Pace of mutation accumulation as the virus evolves. It is commonly estimated adopting statistical phylogenetics
