It isn't so much the number of kits available, it's the number of labs and lab personnel available to process them. What we need is a rapid test, similar to those we now have for Influenza, that provide results on the spot. BTW, that would be 100 x cheaper as well.
Like the ones they have been using in Korea for weeks to get their epidemic under control. They can test 100 times as many people as we can here. Why do you think that is?
