That's a useless number. For any statistics to have meaning, there have to be standards for comparison. And for years, the standard has been number of cases in a comparable population (1,000 - 100,000 - 1,000,000). Otherwise it's just prattle, bordering in inanity.

There also has to be honesty in reporting. We know that the Chinese have hidden the total number of cases.

There are other factors as well, the greatest of which is the type of society in which the virus penetrated. The U.S., and many European countries are fairly open in their population movements. Closed societies, such as China, the Koreas, Mongolia, etc. are not comparable.
