On Dec 3, the New York Times reported that Orange County in California kicked off an ambitious effort to distribute 500,000 home-use saliva test kits to its 3.4-m residents by the end of December. The first do-it-yourself home saliva tests, which require users to simply dribble into a test tube, seal it and send it to a lab, has been sent out to residents. As the tests become widespread, they could provide a less-uncomfortable alternative to nasal swabs and enable more people to safely return to work and school in the months before a vaccine is widely available.
