The Centers for Disease Control and Prevention says "several" airport screeners have been directed to self-quarantine after two contractors who were screening passengers arriving from China at Los Angeles International Airport subsequently tested positive for the coronavirus, according to CDC spokeswoman Kristen Nordlund.
CNN has previously reported on the two positive tests, but not the subsequent quarantine of other screeners. The contractors were working for the Department of Homeland Security.
Nordlund said the CDC and the local health department are investigating the exposures, but don't know if the employees were exposed during their screening duties.
Because the two people who tested positive interacted with other screeners, Nordlund said several others are now under quarantine.
The last day of the screeners’ self-quarantine period is scheduled to be March 17. Currently, these screeners are considered to be medium risk," Nordlund said.
Nordlund said the CDC and DHS are working to re-staff screening operations at LAX, including bringing staff from other quarantine stations.
