Michael:

The important steps in a screening program are:

1. Provide a questionnaire based on the CDC.
1. Do you have a new cough?
2. Do you have now or have had in the past 7 days elevated body temperature?
3. Are you feeling ill now?
4. Is anyone in your family positive or suspect-positive?
5. Have you been exposed to anyone in the past 14 days who is positive or suspect-positive?
6. Have you traveled on mass transportation in the past 14 days?

Amend the questions to suit your needs.  A YES will result in denial of entry to the facility.

2. Set a realistic threshold temperature. 100 – 100.4 F (37.8 – 38.0) is the common trigger range for denial of entry.
3. The screener MUST maintain a 6 foot (2 meter) separation.
4. You must train your screeners fully and be prepared for contingencies.
5. Surgical or cloth facial barrier, faceshield, (plus goggles, though this can become onerous and physical separation should be adequate), gloves, replaced frequently. Disposable lab coat would be beneficial.
6. Persons denied entry should be given written instructions telling them to go home, self-isolate and CALL DO NOT GO TO their healthcare provider.
