"More than 11,000 people are under self-quarantine in the state, according to the California Department of Public Health, meaning they think there's a chance they were exposed to this novel coronavirus..." Where did this number come from? Is there a number to call to report yourself? I live in CA and I haven't seen any of my neighbors since Tuesday, nor have I ventured out myself. Maybe we're all under self-quarantine, but no one asked me if I am. There probably are a few million who are staying home. I just want to know where this number came from and how accurate it possibly could be.
