Demographic and travel characteristics and self‐reported predeparture SARS‐CoV‐2 testing behavior in air passengers entering the United States from foreign destinations from July to September 2021

Abstract

AbstractIntroductionFrom January 2021 to June 2022, the United States Centers for Disease Control and Prevention required predeparture SARS‐CoV‐2 testing for all air passengers arriving into the United States from a foreign country.MethodsUsing data collected during a surveillance project, we described predeparture testing behavior among a convenience sample of international air passengers entering the United States from July to September 2021 at six US ports of entry. We analyzed pairwise relationships between self‐reported test type, test timing, demographic and travel characteristics, and COVID‐19 vaccination status using chi‐square and Fisher's exact tests.ResultsParticipants were more likely to get a NAAT versus antigen test if they identified as non‐Hispanic Asian or Pacific Islander (68.2%, n = 173), non‐Hispanic Black (62.6%, n = 147), or if they preferred not to report race and ethnicity (60.8%, n = 209) when compared to those who identified as non‐Hispanic White (47.1%, n = 1086, all p < 0.05). Those who identified as Hispanic or Latino (n = 671) were less likely to get a NAAT than the non‐Hispanic White group (39.5% vs. 47.1%, p < 0.05). Participants arriving in the US from the Americas were less likely to get a NAAT (38.5%, n = 871) compared to those arriving from Europe (45.5%, n = 1165, p < 0.05). Participants who reported receiving their predeparture test 2 days or 3 or more days before departure were more likely to report receiving a NAAT (52.2%, n = 879, and 60.2%, n = 410, respectively) than those who reported testing within 1 day (41.4%, n = 1040, all p < 0.001) of departure.DiscussionTest type was significantly associated with race and ethnicity, departure region, and test timing. Differences likely reflected regional disparities in the availability of tests at the time of the activity. Discrepancies in predeparture test timing and type worldwide may have consequences for the effectiveness and equity of travel requirements in future pandemics.
