The Wheat Belt, Wheat, Sheep, Wool, Feed Stock (hay) we would never use backpackers, the farmer (owner) is always the header operator and the neighbouring farmers operate the chase vehicles and silo runs. It's flat out almost non stop busiest time of the year.
Wool/feed can be forgiving but as you know Wheat/grain don't wait for anyone, delay the harvest, lose yield. There is still a lot of advertising (right now) for general hands to help out, marshaling etc. Imagine if your header operator gets tested positive for covid a week before harvest, not good, while it is an isolated job in itself would they even be fit to drive especially if older. I know some that would want the ventilator fitted to the cab so they could still harvest.
The chief health officer was asked about this around a week ago. She answered that in many cases it was impossible to tell whether WuHu flu killed them or other conditions.
The UK mortality stats had the the difference as "due" to covid being 75% of cases "with" covid so it's not a huge difference, just take 25% off death rates and you will be close. The "with" covid stat still has to be covid as a causal factor, not the overall cause of death, which could be multiple things, again understanding how deaths are recorded needs to be understood. If the patient died and it had nothing to do with covid at all, but they had covid in their system, covid will not be on the factors list. For instance, "patient decapitated by sword, massive trauma to neck area", even if they had severe covid, that would not be listed as a covid related death.
If the patient could have survived but covid possibly affected their recovery then it gets listed as "with" covid. IF they reattached the patients head and they were recovering, but then Covid killed them via a lung infection then it would become "due" to covid.
