Nothing to do with Delta (nor with your Vlad fetish). This is an increase in deaths of people in the workforce.
If you read the US-published link about Indiana, the head of the main hospital clarified that most patients in ICU did not have covid. ICU bed availability was 6% and this may happen here in a few months.
The CEO stated that in Q3 deaths were up 40% and Q4 results would be similar. Indiana has a population of 6,700,000 is now 52% fully vaxed.
Decide for yourself what has caused these extra deaths.
