|Risks||Definitions||Example 1- Lung Ultrasound Obtainment||Example 2- Personal Exposure Assessment|
|Participant||Participant group (e.g. pregnant woman/new mother, child, older adult woman)||Child||Older Adult Woman, Pregnant Woman|
|Location||Place where sample is collected or procedure performed||Healthcare facility||Home (indoor or outdoor)|
|Proximity to the participant||
Close: The procedure requires the field worker and participant to be closer than 2 m (6 ft) of one another. If a procedure produces aerosolization, then it is automatically considered close contact.|
Socially distant: The procedure to be performed allows the field worker and participant to maintain a distance of > 2 m (6 ft) apart from one another.
Short: The procedure can be performed without the staff and participant in close proximity for > 15 min.|
Prolonged: The procedure requires the field worker and participant to be in close proximity for > 15 min.
Setup: short to prolonged|
None: The procedure is unlikely to produce any aerosolized particles.|
Yes: The procedure may produce aerosolized particles.
|Personal Protective Equipment (PPE) Needs||Criteria to determine PPE||PPE Needs||N95 or equivalent respirator + eye protection + gown + gloves||Paper facemask + eye protection + gloves|
|Participant and staff are not in close contact at anytime. No aerosolizing procedures. No processing of biologic samples.||Paper or cloth facemask.|
|Participant and staff may be in close contact but only for a short period of time. Biologic materials may be processed in the lab. No aerosolizing procedures performed.||Paper facemask (preferably procedural quality) + eye protection + gloves (if the procedure requires touching the participant and/or a clinical specimen is collected.|
|Participant and staff may be in close contact for a prolonged period of time and/or an aerosolizing procedure is occuring||N95 or equivalent respirator + eye protection + gown + gloves.|
|Participant and staff may be in close contact for a prolonged period of time and/or an aerosolizing procedure is occuring in a manner that staff and participants can not be safely protected.||Procedure will not be performed.|
