That seems very strange coming from a hospital. It has been pretty clear from those with medical knowledge that cloth mask do not work to protect the wearer, while N95 protect the wearer but depending on the construction might have a vent that do not filter the air that goes out. The mask that hospital workers need is N95 that also filter the out breath. |
