Facebook using artificial intelligence to forecast COVID-19 spread in every U.S. county

State officials hope California's new 10 p.m. stay-at-home order will slow the spread of COVID-19, otherwise, another 10,000 San Diegans are projected to contract the virus in the next 10 days. That's according to a new county-by-county forecast from Facebook, which rolled out the prediction software last month. Facebook projects L.A. County will see the second-largest increase in cases in the country by November 30. San Diego County is projected to add the 15th most cases, reaching a total of 78,594 infections by Nov. 30. The two-week forecast was released before Governor Gavin Newsom announced enhanced restrictions.
