COVID-19 status	Recommended PPE
COVID-19 positive, confirmed	Respiratora, eye shield, gown and gloves
COVID-19 unknown but patient is symptomatic and has one of the following (test may or may not be sent, presumed positive): • Clinical findings consistent with COVID-19 • Close contact with someone with COVID-19 • Traveled to high-risk area in last 14 days	Respiratora, eye shield, gown and gloves
COVID-19 unknown, test results pending — presumed positive until proved otherwise	Respiratora, eye shield, gown and gloves
COVID-19 negative, confirmed	Patient-appropriate PPE — mask, eye shield and gloves common currently, gown as needed (e.g., spray expected)
COVID-19 unknown but presumed unlikelyb	Patient-appropriate PPE — mask, eye shield and gloves common currently, gown as needed (e.g., spray expected) — could consider respirator for AGP

AGP aerosol-generating procedure

^aBased on Centers for Disease Control and Prevention recommendations, if a respirator is unavailable a facemask should be worn

^bThe categorization of “unlikely” is dependent on epidemiology (community level and patient contacts) and clinical findings
