Since the onset of the COVID-19 pandemic, researchers have noted a disproportionate burden of COVID-19 infection, hospitalization, and death among Black and Hispanic individuals in the United States. In March 2020, the CDC reported that twice as many Black individuals were hospitalized with COVID-19 than were proportionally represented in the U.S. These disparities may be […]

We explored the relationships between various factors and vaccine hesitancy over time, and the association between hesitancy and subsequent vaccine uptake among populations eligible to be vaccinated. We found that while vaccine delay has decreased significantly in the cohort between October 2020 (before vaccines were available) to July 2021 (when vaccines were widely available), vaccine […]

We analyzed data from the discrete choice experiment on SARS-CoV-2 testing features and found five distinct patterns of preferences among our participants: Noninvasive home testers, who were the most strongly influenced by specimen collection methods and preferred less invasive methods; Fast-track testers, who were most influenced by result turnaround time, favoring immediate and same-day results; […]

About half of the CHASING COVID Cohort participants who are parents reported that their children were vaccinated against COVID-19 when they became eligible. Parents’ hesitancy to vaccinate their children against COVID-19 differed by parental race and ethnicity, gender, education level, and previous experience with COVID-19 and the child’s age, with older children more likely to […]

We explored the relationships between individuals’ behaviors, risk perceptions, and decisions to gather with other households during Thanksgiving in late November 2020 and the risk of subsequent SARS-CoV-2 test seeking and diagnosis. We found those who regularly engaged in higher COVID-19 risk activities and those who had a low-risk perception of COVID-19 were more likely […]

The CHASING COVID Cohort has conducted two rounds of serologic testing for SARS-CoV-2 antibodies, the first from May to September, 2020 (Period 1), and the second from November 2020 to January 2021 (Period 2). In a recent pre-print, we assess the cumulative incidence and recent incidence among the 4,235 participants who provided samples in Period […]

We explored CHASING COVID Cohort participants’ beliefs about the coronavirus and claims they saw on social media using responses from the baseline screening survey from March 28 to April, 20 2020, before much was known about the virus. At that time, the top three trusted sources of COVID-19 information were the United States Centers for […]

35% of CHASING COVID Cohort participants reported experiencing moderate or severe symptoms of anxiety. Individuals who had lost income due to COVID-19, reported recent COVID-like symptoms, and had previously been diagnosed with depression were more likely to report symptoms of anxiety. For more information, click here. The common experience of anxiety symptoms among participants highlights […]

Study participants were more likely to be hospitalized due to COVID-19 if they had children in the home (compared to participants without children in the home) and if they lived in multi-unit dwellings (for example, apartment buildings) compared to participants living in single-unit dwellings. These findings may have implications for mask-wearing and other mitigation strategies […]
