The excess deaths in USA according to John's Hopkins etc were due to covid.
BTW, as background, every year most countries track who dies and when. Over the years, mild seasonal patterns emerge. But it's an average. Thus, they know that it will fluctuate within a standard deviation of average, up and down randomly. In other words, there is a range of expected deaths from month to month. When the deaths are outside of that range people get alarmed. Covid for sure did that, suggesting it was not just a cold.
Throughout my life every quack "coral calcium" or miracle drug person says the same thing: the medical establishment is trying to hide results, suppress info, "info they dont want you to know " etc. (Think of the used car salesman Kevin Trudeau hawking all those miracle cures, etc. I believe he ended up in gaol).
Thus anytime I hear information conspiracies in health care I go back to the fraudsters. If they had hard evidence don't you think they'd love to show it?
