Why are some Southern California casinos still open during coronavirus pandemic? Jeff Horseman and Alex Groves, Press Enterprise · March 18, 2020 at 2:57 am While a number of Southern California casinos have shut their doors to limit the spread of the novel coronavirus, some were still open for gambling as of Monday afternoon, March 16. This despite Inland county bans on gatherings of 250 or more, the U.S. Centers for Disease Control and Prevention urging the cancellation or postponement of gatherings of 50 or more for eight weeks and a wave of other closures – including schools, bars, wineries, and breweries – in response to the COVID-19 pandemic that has sickened almost 170,000 and killed more than 6,500 worldwide. In California, more than 330 coronavirus cases have been confirmed – 15 in Riverside County – with six deaths blamed on the disease. Gov. Gavin Newsom has urged those 65 and older to self-isolate at home.
