Indeed, I too have read that the test out there is garbage, leading to mostly false positives. In that case, the mortality rate COULD be much higher than announced, but the number of people who actually have it much lower. So, if they claim that 100,000 people have it, perhaps 80,000 of those have some other strain of corona. Nobody really knows, and this is a huge mess.
If the tests give false positives, as they test more people,
the number of deaths remain the same, but the death
rate percentage will keep going down. In Germany where they have tested more people, the death rate is below 1/2 of 1%. PLUS, they have no test to confirm that they died of Covid19, so even the cause of deaths are speculation.
I have a friend and he and his wife are in their 80's, he got pneumonia about 2 months ago and was in the hospital for one week. Then his wife got pneumonia, but not quite as bad.Now their 57 year old son got it 2 weeks ago week. The two parents were told they had pneumonia because it was before the "pandemic". The son will likely be told that it is "the "Corona Virus", I'll have to get back to you on that one. I would be far and away believe that it was all pneumonia (very common in the USA) than some virus that somehow traveled from half way across the world from a place I never even heard of, Wuhan.
