Any number is possible with the amount of environmental H5N1 contamination at this point. Dairy cattle farm or no. And I don't think it means only people either. I am talking about all manner of wild avians and mammals contamination that ends up in the storm drain systems. We are saturated.
For me the wastewater data is in the interesting category. It is a data point to look at but provides no detail.
Honestly, we are so screwed. It is everywhere.
