Coronavirus is winning the battle in El Centro, California. It’s in almost every patient in the hospital. Tents are being put up to handle even more cases. It’s on the streets, forcing rescuers to put on protective suits and cumbersome masks before they approach people needing help. And it’s not stopping. Even as nearby and faraway facilities take patients to try to ease the load, more and more sick people keep coming. And so do the deaths. The workers are exhausted. The virus is not.
