People with coronavirus are crossing the US-Mexico border for medical care

An ambulance crosses the San Ysidro sentry box border crossing on April 27, 2020 in Tijuana, Mexico.

(CNN)Chris Van Gorder says he's seeing a telling trend in the hospitals he runs.

Coronavirus patients are showing up in emergency rooms after calling 911 from the US-Mexico border.
"They'll literally come to the border and call an ambulance," says Van Gorder, president and CEO of Scripps Health, a hospital system in southern California.
    The rise in ambulance traffic from the border, which several officials described to CNN, is a symptom of the pandemic's spread in the region -- and a sign of the many connections between communities in both countries.
