The WHO has confirmed that aerosol transmission is a possible transmission pathway of SARS-CoV-2. WHO has published
guidance intended for healthcare workers (HCWs), healthcare managers, and teams working in infection prevention and
control. WHO recommends that eye protection (goggles or a face shield) be used during patient contact along with gloves, a
medical mask, and a fluid-resistant gown. Airborne precautions, including an N95, FFP2, or equivalent respirator, should be
used during aerosol-generating procedures.
Infection prevention and control during health care when novel coronavirus (nCoV) infection is suspected
The U.S. Centers for Disease Control and Prevention (CDC) has recommended that healthcare workers entering the hospital
or clinic room (in a healthcare facility) of a suspected novel coronavirus case use standard precautions, contact precautions,
and airborne precautions. This includes non-sterile gloves, a disposable gown, respiratory protection that is at least as
protective as a fit-tested NIOSH-approved disposable N95 filtering facepiece respirator, and eye protection (e.g., goggles, a
disposable face shield that covers the front and sides of the face).
Interim Infection Prevention and Control Recommendations for Patients with Suspected or Confirmed Coronavirus Disease
2019 (COVID-19) in Healthcare Settings
These organizations have also offered guidance for organizations facing a shortage of respirators during this pandemic:
• Strategies for Optimizing the Supply of N95 Respirators
• Rational use of personal protective equipment for coronavirus disease 2019 (COVID-19)
Those potentially in contact with suspected or confirmed cases of this novel coronavirus should review all recommendations
by the WHO, CDC, and other health authorities.
