Understanding Factors Influencing COVID-19 Testing and Vaccination in Immigrant, Low-income and Unhoused Populations, and Testing Targeted Interventions [3U54GM115516=04S2 RADx-UP]

The COVID-19 pandemic has disproportionately affected people from underserved and vulnerable populations such as low-income/uninsured, unhoused, and immigrant communities. These populations in the US are at a higher risk of acquiring COVID-19 because of poverty, type of occupation, greater use of public transit, living in multigenerational housing, lack of access to quality healthcare, and more. Despite greater risk of being infected and dying of COVID-19, those in disadvantaged communities are less likely to get tested. The investigators are collaborating with community partners in Cumberland County, Maine to implement a public health intervention focused on making COVID-19 testing more accessible to underserved populations. The intervention includes a one-time in-person training on how to take an at-home COVID-19 test and then provision of at-home COVID-19 testing kits to make testing more accessible. Five testing kits are provided at the time of training and then provided every two months for a year, for a total of 35 testing kits.

In this study, the investigators will evaluate the impact of the at-home testing kit intervention on COVID-19 testing behavior, knowledge and attitudes. The investigators will accomplish this aim by following a community cohort, with a goal of recruiting 150 participants - 15 participants from each of our 10 population groups of interest (three groups that access different health services for low-income/uninsured, unhoused individuals, and six different immigrant groups). The investigators will administer surveys to the cohort participants every month over a 12 month period. Every month the survey will ask about testing behavior, and every other month the survey will also ask about knowledge and attitudes towards testing. In order to ensure access to COVID-19 tests, the cohort participants will be provided at-home testing kits throughout the course of the study. The primary outcome of interest is "recommended testing behavior," which is defined as taking a rapid COVID-19 test when experiencing symptoms of COVID-19 or after a close contact exposure.

The investigators hypothesize that knowledge about testing, favorable attitudes towards testing, and recommended testing behavior will increase as a result of participation in the study.
