It really isn't. Sadly. For all the destruction they cause viruses are basically simple - they infect a host and replicate. If they are thwarted in that replication they mutate to try again. They will continue to infect hosts until they are stopped by either running out of hosts or from human created medicines designed to stop them - or at least slow them down so they can be survived with other medical interventions. As long as there are hosts (our fellow humans) available to infect there will more variations of the virus to start the cycle over. It's how they act. They don't have beliefs or intent. Viruses just act.

Wishing you well Linda.
