Dr. Tien Vo carries food for a family quarantining after testing positive for the coronavirus Thursday, July 23, 2020, in Calexico, Calif. Vo moved to Imperial Valley ten years ago. He says he stayed because people are friendly and appreciative. He sees happiness in their eyes when they greet him. "They really need a doctor here," he says from the front seat of a company van between house calls. "They're not very hard to please. They chat with me. They text me every day."
