In Puerto Rico, they are taking passengers’ temperatures at the island’s largest airport. In Wisconsin, they escorted cruise ship passengers back to their houses for quarantine. In Florida, they are swabbing people’s noses near Miami to test for the coronavirus.

At least 7,300 National Guard members are aiding in the coronavirus response in all 50 states, as well as in Washington, D.C., and Puerto Rico, as of Sunday morning, according to Army Maj. Rob Perino, a spokesman for the National Guard Bureau in Arlington, Va. He warned that the numbers could change rapidly as states modify their response to the virus, which continues to sicken more people each day.

When Guard members have been deployed, the sight of camouflage-clad troops and military vehicles has prompted false rumors of martial law and military-enforced quarantines. But Guard members are currently being ordered to complete tasks that are much more mundane.

In New Rochelle, N.Y., a suburb of New York City that has been hit hard by the virus, members of the Guard unloaded pancake mix and rice and cleaned public buildings. In West Virginia, they taught emergency workers how to properly use and decontaminate protective equipment.
