Omotigre, mi dispiace molto. Condoglianze.
Copio incollo da reddit/askscience questo post che risponde alla domanda di OP:
"Cosa succederebbe se teoricamente tutto il pianeta si isolasse per un mese? Riusciremmo a eliminare il SARS-CoV-2 e tutte le sue mutazioni?"
The big issue with covid is that it came from an animal host and jumped into a human one. That means the virus is capable of doing the reverse, this is why news like tigers and lions being infected by an asymptomatic zookeeper are a big deal.
Not so much that the tigers and lions got sick but that it shows the virus is capable of finding another reservoir outside the human population, and one that exists around most humans, cats.
Now, I'm not sure how far tigers and lions are from domesticated cats in terms of their genetic make up, but if you can, try and imagine that this virus is able to take hold within the domestic cat population. Now you have another reservoir that has close contact with a myriad of other animals and humans, each of these hosts is then capable of providing an environment where the virus can naturally mutate.
Covid is a single stranded RNA virus, that is they use rna to hold their genetic information not DNA. Single stranded rna viruses are easy to copy because unlike DNA, there is only one strand so making copies is faster, but the enzyme that makes the copies, rna transcriptase is generally more error prone than its DNA counterpart and the rna enzyme doesn't have the ability to correct genetic mistakes during the copying process so more mistakes means more variation in the virus, more variation means that there is a greater chance of finding its way into another host, or just becoming more pathogenic.
Most pathogens aren't actually trying to kill off their hosts, it's more of an unintentional action of being particularly virulent within a specific host, this is more evident with a virus like ebola where once it made the jump to humans, the mortality rate was very high. In it's natural reservoir host that wouldn't be the case because the virus doesn't really want to kill off all of its hosts. That would be an evolutionary dead end for the virus and it would run out of hosts to infect.
If you are interested in this, reading spillover by David Quammen would be a great way to learn about the history of these zoonotic diseases.

My 2 cents.
