So yes, all of those letters up to omicron, except for two, have been different variants. A virus that can party globally has a lot of chances to mutate. Some of those are worrisome, others not. So unless you follow this closely you have not heard of the epsilon or kappa variant. I am sure some conspiracy nitwit will tie this to the Chinese because the letters have been skipped. UGH
Not too many greek speakers here either
