we need a better handle of what's going on in these high-end labs around the world where these risks are being created. >> as you can imagine, there are a lot of viewer questions, and i want to round out with a couple questions from our viewers. one asks -- and i'm personally curious about this, too. how can the biden administration help make low-cost or free rapid testing widely available? what is the step-by-step approach to get it done? >> there are a lot of tests on the market but they're not the tests consumers want. consumers want a test that can give a rapid result that are easily performed inside the home and don't necessarily require the result to be reported, that they give you discretion to report the results or manage the results of the tests and they're not overnight tests, so things like the binex test from abbott. i think the administration could do more to assess these tests, particularly the low-income communities, people who work in essential jobs who might not be able to afford repeated tests.
