The proposed research investigation should encompass:
A. Investigate how the March 13, 2020 DHS Notice of Arrival Restrictions (NAR) affected the designated arrival airports.
B. Determine COVID-19 health screenings protocols and self-quarantine recommendations at each airport for returning travelers.
C. Did airports follow their Communicable Disease Preparedness plan for the COVID-19 event, and if so is the plan adequate for this emergency.
D. Determine usage of the airports implement the use of the ACRP Synthesis 83 Checklist for Airport Communicable Disease Response Planning.
E. Model the potential impact of hand hygiene behavioral changes on COVID-19 risk if such changes were implemented at the 13 arrival airports identified by the NAR.
