From what the numbers are saying it looks like the USA is both under-testing and over-reporting simultaneously. Very odd state of affairs. I'm ignoring the total cases number from the USA at present because it is a clear outlier. The # of deaths is much more reliable but that number will lag as tests are performed.

(The # of deaths for Germany is suspiciously low, as is the # of deaths for S. Korea.) I actually think the Chinese data is fairly accurate. the Iranian data, well, who knows. I'd like to think the European data is reliable, but again, who knows.

If the USA becomes a hot-spot then other countries will undoubtedly institute a travel ban to/from there like is happening with parts of China, S. Korea, Italy, Iran, and so on.
