It's expected for a quickly mutating virus to show slight genomic variations in different sample strains though. If you sequence humans, their DNA wouldn't exactly match either.
You're right about different strains, but that alone shouldn't be the reason for categorizing it under a different label altogether. They even gave a separate name to the illness caused by this virus, as if people never experienced such symptoms before!
