Yuma County, Ariz., which produces the lettuce, broccoli and other leafy greens that Americans consume during the cold months, is known as “America’s salad bowl.” Now it has become a winter hothouse for Covid-19. Over the course of the pandemic, the Yuma area has identified coronavirus cases at a higher rate than any other region in the United States. Even as coronavirus cases are starting to flatten across the country, the virus is still raging in many border communities. Three of the six metro areas with the highest rates of known cases since the outbreak began are small cities straddling Mexico: Yuma; Eagle Pass, Texas; and El Centro, Calif. In Laredo, Texas, cases are increasing at more than three times the rate being reported in hard-hit Los Angeles and Phoenix.
