No one knows how many are infected with shortage of test-kits.
Symptoms of covid-19 are similar to flu, and we already know tens of thousands are sick with flu. So is it flu or covid-19?

There is a lot of crossover and commonality in symptoms, but COVID-19 isn’t identical to the flu, and many cases are unlikely to be confused, even without test-kit confirmations. There are bounds to how many would be confused one with the other - which doesn’t make it not a problem either.
