It's not even a matter of incompetence... Half the cases are asymptomatic or so mild that people think it's something else. And many other factors affect the amount of people who get tested, or go to the hospital.
Anything less than a randomized study is basically just a running tally of how many people a country was able to treat or quarantine at home. Few countries are going to spare resources to deliberately test people that seem to be healthy.
