In the middle of March, Luc Bernard came down with something he had never felt before. He had a constant cough, trouble breathing and couldn’t get to sleep. Fearing he had the novel coronavirus, he went to the hospital. Back then, it was hard to get tested. Instead, doctors told him to go home and self-isolate. But that’s not easy when you live in Park La Brea, surrounded by more than 10,000 people, all connected via elevators, hallways, tree-lined paths and parking lots. Bernard told his landlord, Prime Residential Apartments, that he planned to sequester himself in the two-story, three-bedroom apartment he shares with a roommate. So he was surprised to come downstairs one morning to find a maintenance worker fixing a broken light in his kitchen.
