Print Outbreaks at restaurants and retail spaces fell drastically during the most recent stay-at-home order, according to new San Diego County public health data — a finding that suggests COVID-19 regulations, as painful as they may be, are effective at slowing the spread of the virus. In the wake of California’s regional stay-at-home order, which required the closure of many business operations, outbreaks in community settings fell by just over 25 percent, from 347 to 258. A significant decrease in outbreaks at restaurants and retail spaces accounted for most of that drop. In the six weeks leading up to the Dec. 3 order, 72 outbreaks were reported at restaurants and 40 were noted at retail locations, the data show. In the six weeks after the order went into effect, there were only four outbreaks at restaurants and three at retail spaces.
