Check the reports coming from Italy/Spain that the Chinese test kits they've received are only 30% accurate. Testing 10 known infected the kits reports 3 are infected, and 7 as not.

So if China is using similar kits, which is what is supposedly happening, they could have almost 3x the cases they are reporting.

Or, they are shipping inaccurate tests to rest of world to "help"

Either situation is very concerning.

It does not matter much whether the tests are 30% accurate. See... this is exponential growth. Due to its nature it will overrun any linear factors in a short time.

What if the reported Chinese numbers are only 30% of reality compared to US numbers? If you understood the nature of exponential growth you would know it will take just about 4 days for US to have three times the numbers China has.

It currently only takes US about 8 days to increase the number of cases tenfold (see here: https://www.worldometers.info/coronavirus/) which means 4 days to get 3 times increase.

What really matters is to get people to stop moving around and spreading the virus.
