This interim guidance has been updated based on currently available information about COVID-19 and the current situation in the United States, which includes community transmission, infections identified in healthcare personnel (HCP), and shortages of facemasks, N95 filtering facepiece respirators (FFRs) (commonly known as N95 respirators), eye protection, gloves, and gowns.
Current data suggest person-to-person transmission most commonly happens during close exposure to a person infected with the virus that causes COVID-19, primarily via respiratory droplets produced when the infected person speaks, coughs, or sneezes.
