With the 2 variants of Omicron BA.4 and BA.5 surging around the world (western world in any case) there has been a steady rise in case numbers in the world. Deaths are just starting to rise in response.
Besides the variants BA.4 and BA.5, the large virus pools in these countries like Australia, United States, France, UK, Germany, generated by vaccine complacency has already started to generate a host of new vaccine induced subvariants like BA.5.2.1, BA.5.2, BE.1, BF.1, etc..
Covid is more intense in western countries because of vaccine complacency, or ignorance of what the virus can do spread by their governments and happily accepted by the woke who are still sleeping.
Look how low the world is when you do it relative to per capita.
It is ironic that the pandemic could have been stopped quite easily 3 times but the world was in a hurry to hit the road again. Now they shall have to live with this curse.
