The team at Flinders University in Adelaide and Latrobe University in Melbourne studied how well SARS-CoV-2...infected different animals....
Professor Petrovsky expected to find an animal that was most susceptible to this, such as bats, ... but was shocked when humans came out on top.
Furthermore, viruses tend to get better at infecting new species as they adapt over time, but COVID-19 started 'completely optimised from day one without the need to evolve'.
'This is a new virus that has never been in humans before, but it has an extraordinarily high binding to human receptors, which is very surprising'
