The first recorded instance of coronavirus community spread in California was tracked to a nail salon, Gov. Gavin Newson said Thursday. The governor made the revelation as he explained why Golden State manicurists aren’t slated to reopen Friday, when other businesses, including clothiers, sporting-goods stores and florists will resume limited operations. “This whole thing started in the state of California — the first community spread — in a nail salon,” Newsom said during his daily briefing. “I’m very worried about that.”
