As COVID-19 rages across Europe, the commander of U.S. European Command Gen. Tod Wolters told media that 2,600 U.S. troops were “of concern” and that he had canceled readiness exercises and is regularly speaking to all NATO partners.

“We’re preparing for worst-case scenarios with respect to the potential spread,” he said on a press call Friday from EUCOM headquarters in Stuttgart, Germany. “For months, we have embraced precautionary measures.”
