This is a relatively old recombinant cluster likely from India-MH that I used to be monitoring since August. I was surprised to see it's still growing after almost a month of hiatus in September/October, and this time in a geographically distant areas (mainly Canada and the US).

Interestingly this pattern of hiatus and reemergence is similar to #896 , which is another BA.2.76/BA.5.2* recombinant.
