I'm curious what your basis of saying that it hasn't been isolated is?

Are you saying that because no one has gone to collect that cash from that person who offered a reward to anyone who isolated SARS2 via the koch postulate?koch's postulate is an outdated method of isolating BACTERIA.

You can't culture a virus on agar,not requires live cells.

Koch's postulate also requires that the microorganism in question be collected from a infected person, cultured on a medium and then used to reinfect another person to ensure the same symptoms manifest.

So there are some ethical, and legal problems with that approach. You might get arrested for murder or attempted murder if you were to purposely infect a person with the virus.
