I don’t think anyone is suggesting that there aren’t numerous countries with the delta variant, however, it’s accounting for around 5% of cases in a lot of countries (US had less than 10k cases in the entire country this week).
An interview with someone at the CDC or Department for Health or whatever they call it basically said that at those numbers they can easily test, trace and isolate those and their contacts.
We have 95% of our cases being this variant and the horse has bolted unfortunately. We were inundated from the start and had no chance of controlling it.
If it had been a handful of delta and the majority Kent variant with the current vaccination numbers we’d be laughing and not now hoping that this “Delta Plus” variant doesn’t kick off.
