Top health care officials said Monday that there is not enough stockpiled medical equipment like masks, gowns and gloves to fulfill the anticipated need of nation’s health care system as it deals with the coronavirus.

Officials from the Department of Health and Human Services told medical professionals on a conference call Monday that there was not enough personal protective equipment in the Strategic National Stockpile to fulfill anticipated gaps in state and local supplies, according to a source who was on the call. The call was confirmed to CNN by a Department of Health and Human Services official.

The officials, from HHS’s Office of the Assistant Secretary for Preparedness Reponses, said on the call that the government didn’t yet have a solution for the looming shortfall, but was working on one.
