U.S. Northern Command has begun to implement action plans due to the spread of the coronavirus. Approved by Defense Secretary Mark Esper, these plans include ordering commanders to prepare for a widespread outbreak and to confine service members who have travelled to China. The Department of Defense Global Campaign plan for Pandemic Influenza and Infectious Diseases 3551-13 has been reported to have been implemented by U.S. Northern Command. Navy Lt. Cmdr. Mike Hatfield has commented that these actions are not a cause for concern by the American people, however. Being prepared is the goal, and how the military will respond in the case of a wide-spread breakout is being discussed.
