Where is the correct data on coronavirus?

Question

Imagine the scenario (which is likely in some countries) that most of the population contracts COVID-19 in a very short timeframe.The most important question for most of people in the Western world is then: For a healthy person of my age, what is the chance I will require hospitalization if I contract coronavirus?This question does not depend on R0, measures taken to prevent the spread of the disease, population distribution, ..., nothing. Therefore, it should not differ much across different circumstances.Except, the relevant data from different countries are contradictory by orders of magnitude.Is there a single country in the world that has a nontrivial amount of cases, and has actual data and not absolute garbage?

This sheet is the best that I've found. Yes, you are right, the data is suspect. But as long as there is no mandatory reporting for this it will remain a political football because countries are comparing with each other.

The best way to approach the figures is to look at serious cases (requiring hospitalization) and deaths. Those are numbers are a lot harder to cook than cases.
