The thing about testing means nothing unless people can figure out a death rate and how it compares to other diseases.
The more positive tests confirmed may simply mean a country does more testing.
In terms of rate per 1000 people, a high rate means there's more people with covid per allotment, but remember that just because you test positive for something doesn't mean it's super serious or death.
Right now, if every one of us did a test for any of the 100s of flu bugs out there, don't be surprised if many of us have some flu bugs in our blood despite feeling perfectly fine.
In fact, I find it hard to believe all of our bodies are 100% free of viruses at any given time and the only time any virus gets in our body is for that 3 day stretch we blow our nose and then the other 362 days of the year we're 100% clean and there's zero pathogens among our trillion cells.
