Rockerfeller Foundation Report I copied the bit below from the report as I thought this was very significant for SONA. They need screening.. that's Antigen to reopen schools etc. 'safely'. Would require 200million tests each month.
"The United States needs far more tests because the United States has far more Covid-19 infections. At present infection rates, a basic screening strategy will require approximately 200 million tests each month for students and staff at the nation’s primary and secondary schools and residents and staff at nursing homes for them to open safely and in stages. But fewer than 25 million Covid-19 tests are now reported monthly in the United States. Even if infection rates decline, the testing needed in just schools and nursing homes exceeds the nation’s entire capacity now.
But the nation’s capacity to conduct screening tests is rising, and is projected to grow much further. By October 2020, based on recent and announced expected market entry, point-of-care tests will rise to at least 70 million tests per month. By January, that number could rise to almost 200 million tests per month. More growth is possible – if additional tests enter the market, if additional research laboratory capacity is recruited and supported, and if manufacturers make further investments to increase supply."
