Statistics for new Covid-19 cases are unreliable.
No, I do not believe that that one specific example of why the methods of recording cases of covid and recording covid-related deaths is widespread.
What I do think is that that example serves as a good example of why some of the methods of recording covid cases and covid-related deaths are bad, and leading to bad data.
If you want to know how many people have covid and the test to detect covid has a 30% false positive rate then you can't just look at how many people test positive. The reason you can't do that is because someone could test 1 million people that don't have covid and the results would come back that 300,000 of them have covid, even though none of them have covid. Then it would be very easy to mislead people by printing a headline "300,000 new cases of covid!"
