I actually looked at the site Watu linked to. I've never heard of it, but I wouldn't trust it. For one, they have a "9/11" tab, and I don't understand why any reputable news agency would still have a dedicated tab nearly 20 years later unless it was conspiratorial nonsense. But otherwise, they try to link the lung collapse deaths from vaping last fall with COVID-19 to prove it was here before it was in China. They make the specious unsupported claim that vaping does not explain the deaths.
While it is true we can't fully explain what caused the spate of vaping deaths, it was decidedly linked to vaping. There were a couple thousand cases through the end of the year 2019. And there were NOT a couple thousand cases of random lung collapse in otherwise healthy people among people who didn't vape. Further, those cases were investigated very carefully for commonalities, and no common viral infections were found. Vaping (and specifically vaping THC products) was the commonality. The symptoms and progression is similar enough to fuel some theories I am sure, but the vaping illness is fundamentally a lung injury vs. an infection.
The other claim that some early COVID deaths were blamed on the flu is true, I am sure. But it signifies nothing. COVID complications look a lot like flu complications, and flu tests can sometimes give false positives/negatives. Further, the flu test is more readily available at every hospital and takes ten minutes to get a result so you would always do that one first. If it gives a false positive, they probably aren't going to retest you for COVID given the testing shortage (at least not for awhile). So you will be labelled as "flu patient" and counted in those numbers if you die. So what? To quote everyone's favorite politician, "What difference does it make?" Someone getting misdiagnosed with a similar and more common (at least until very recently) illness is not evidence of any sort to support their claims.
I'll stop there. Sorry that was a much more detailed breakdown than necessary, but I am stuck at home and bored.
