Quarantine is a measure taken to reduce the spread of a contagious disease by temporarily restricting the movement of those who have likely been exposed to it. It has historically been used as a front-line response during public health contagious disease emergencies (National Academies of Sciences, 2020). Beginning in December 2019, quarantine measures were heavily utilized as a preventative strategy to limit the spread of the emerging coronavirus (COVID-19) infection. The Centers for Disease Control and Prevention (CDC) initially recommended a 14-day quarantine period on January 1, 2021. Subsequently, this duration was revised to 5 days and now has limited quarantine recommendations, which account for the evolving understanding of COVID-19 science (Centers for Disease Control and Prevention, 2021). While the recommended time period for quarantine in response to COVID-19 has fluctuated, considering the continuous evolution of viral variants, implementation of pharmaceutical vaccinations, and economic pressures it poses, the Centers for Disease Control and Prevention (CDC) continues to promote quarantine as an effective preventative measure to reduce COVID-19 infections (Centers for Disease Control and Prevention, 2022). In the absence of relevant federal-level policy in the U.S., contradictory and unclear guidance during the initial stages of COVID-19 disrupted healthcare coordination, leading to inconsistent responses at state and local levels, which in turn affected the enforcement of quarantine measures and influenced individuals' willingness to comply with quarantine recommendations (Serchen et al., 2023). Quarantining recommendations, while effective in reducing COVID-19 cases, introduce a myriad of challenges for individuals.
Quarantine poses a financial burden that results in lost wages, especially difficult for those employed in low-wage earning occupations, as they often do not have paid sick leave. Thus, job attendance has been prioritized over health in order to remain financially solvent (Bodas & Peleg, 2020). Notably, over half of the low-wage occupations in the U.S. workforce were also defined as essential employment, putting a compounded risk on an already vulnerable population (Kinder & Stateler, 2021). In addition, self-isolation has been shown to be nearly impossible for families with conflicting responsibilities of childcare, elder care, and a lack of designated space within the home to isolate (Machida et al., 2020).
Among many who were able to quarantine, lengthy periods of isolation had adverse psychological impacts. Prominently, children and caregivers reported increased psychological stress, anxiety, and depression associated with isolationism during COVID-19 (Demaria & Vicari, 2021). Further, interruption to children’s daily routine due to the pandemic has been determined to be associated with numerous negative effects on sleep, personal relationships, educational performance, and overall learning skills, many of which were seen more severely in children from marginalized populations and disadvantaged backgrounds (Amin & Parveen, 2022). Adverse physical effects have also been noted in association with lengthy quarantine (Flanagan et al., 2021). Limitations in geographic movement equate to limitations in healthy food access and limitations on physical exercise, and in turn have been identified to be associated with weight gain, reduced physical activity, and adverse psychological consequences (Zeigler, 2021). Lastly, prolonged quarantine can impact compliance with quarantine regulations, which did not support infection reduction (Liu et al., 2022).
Understanding quarantine adherence in Missouri during the early stages of the COVID-19 pandemic is essential to improving future public health responses. Although there was initial resistance for a statewide stay-at-home order, one was eventually issued from April 6 to May 3, 2020 (Erwin et al., 2021). However, inconsistent public health messaging and fragmented local governance contributed to widespread confusion (Acosta et al., 2021). A study using mobile device data showed that Missouri had one of the smallest reductions in average travel distance nationally, just + 1.9 miles, indicating limited behavioral change (Lee et al., 2020). This was particularly concerning given a St. Louis–based study modeling estimated that a two-week delay in distancing may have led to nearly significantly more deaths by end of 2020 (Geng et al., 2021). Missouri’s limited outbreak data infrastructure further hampered timely decision-making (Acosta et al., 2021). As a state with a diverse population—including urban Black and African American communities and rural white and Republican residents—Missouri experienced distinct barriers to quarantine adherence and faced different challenges and levels of skepticism, that were not just anchored in race, education, and annual income (Shacham et al., 2021). These variations highlight the inadequacy of broad policy models and underscore the need to understand localized behaviors and perceptions to better prepare for future health emergencies.
The ability to quarantine, although effective in infectious diseases, including COVID-19 prevention, may not be a reasonable intervention. It is essential to explore how individuals first received recommendations for quarantining. The purpose of this study was to identify characteristics associated with the ability to quarantine during the COVID-19 pandemic in an effort to assess the likelihood of adherence to quarantine recommendations in the future management of infectious diseases. This study was conducted to better prepare for the future by enhancing quarantine prevention efforts. Understanding the barriers to self-quarantine behaviors is limited, and this may provide practical tools to support individuals and families as they navigate an infectious disease in the future.
