Facilitated Self-Sampling Intervention (FSSI)
Participants in the FSSI arm will receive education on COVID-19 testing and be provided with rapid antigen tests. Participants will also receive pre and post surveys. Facilitated Self-Sampling Intervention (FSSI): CHWs will consent and enroll participants to the FSSI from the randomized PBGs. FSSI will consist of Community Health Worker (CHW) delivered education intervention about COVID-19 testing at a home visit. In addition, the participant will receive a batch of 4 rapid antigen tests which can be shared with people in the household or other close contacts if needed. The CHWs will provide low-literacy instructions for administering the tests, including print and video. The CHWs will also provide guidance if they tested positive (e.g. quarantine, notify contacts, wearing a mask). The CHWs will also be available by phone to the participants for any follow-up questions. CHW will follow-up via text and phone with the participants during the two months post intervention. In addition to the intervention, the participants will be asked to complete the pre and post test surveys. Post surveys will be administered online or over the phone two months after the initial intervention.
Testing Navigation Intervention (TNI).
Participants in the TNI arm will receive COVID-19 testing education and be navigated to PCR testing sites. Participants will also receive pre and post surveys. Testing Navigation Intervention (TNI).: CHWs will consent and enroll participants to the TNI from the randomized PBGs. The TNI will consist of CHW-led intervention at a home visit where they will provide low health literacy materials about how and when to conduct a COVID 19 test (including antigen and PCR) using a decision tree model and provide navigation to nearby PCR testing sites, locations to purchase antigen tests and support in accessing federal government antigen tests if not already obtained by the participant. In addition to the intervention, the participants will be asked to complete the pre and post-test surveys. Post surveys will be administered online or over the phone two months after the initial intervention.
Control
Participants in the Control Group arm will receive a CDC-designed COVID-19 testing brochures, and pre and post surveys only. Control: Participants in the Control arm will receive CDC-designed COVID-19 testing brochures, and pre and post surveys only.

SECONDARY outcome

Timeframe: Baseline

Population: Data was only collected from participants who provided a response.

The percentage of individuals within each participant's self-identified community network who have tested positive for COVID-19. Participants provide a list of individuals they regularly communicate with (community network). The percentage is calculated for each participant as: (Number of community members reported positive for COVID-19 ÷ Total number of community members listed) × 100. Higher percentages indicate greater COVID-19 exposure within the participant's community network.

Testing Navigation Intervention (TNI).: CHWs will consent and enroll participants to the TNI from the randomized PBGs. The TNI will consist of CHW-led intervention at a home visit where they will provide low health literacy materials about how and when to conduct a COVID 19 test (including antigen and PCR) using a decision tree model and provide navigation to nearby PCR testing sites, locations to purchase antigen tests and support in accessing federal government antigen tests if not already obtained by the participant. In addition to the intervention, the participants will be asked to complete the pre and post-test surveys. Post surveys will be administered online or over the phone two months after the initial intervention.

SECONDARY outcome

Timeframe: Baseline

Population: Data was only collected from participants who provided a response.

The percentage of individuals within each participant's self-identified community network who are reported to be vaccinated against COVID-19. Participants provide a list of individuals they regularly communicate with (community network). The percentage is calculated for each participant as: (Number of community members reported to be vaccinated against COVID-19 ÷ Total number of community members listed) × 100. Higher percentages indicate greater COVID-19 vaccination coverage within the participant's community network.

Facilitated Self-Sampling Intervention (FSSI)
n=119 Participants
Participants in the FSSI arm will receive education on COVID-19 testing and be provided with rapid antigen tests. Participants will also receive pre and post surveys. Facilitated Self-Sampling Intervention (FSSI): CHWs will consent and enroll participants to the FSSI from the randomized PBGs. FSSI will consist of Community Health Worker (CHW) delivered education intervention about COVID-19 testing at a home visit. In addition, the participant will receive a batch of 4 rapid antigen tests which can be shared with people in the household or other close contacts if needed. The CHWs will provide low-literacy instructions for administering the tests, including print and video. The CHWs will also provide guidance if they tested positive (e.g. quarantine, notify contacts, wearing a mask). The CHWs will also be available by phone to the participants for any follow-up questions. CHW will follow-up via text and phone with the participants during the two months post intervention. In addition to the intervention, the participants will be asked to complete the pre and post test surveys. Post surveys will be administered online or over the phone two months after the initial intervention.

SECONDARY outcome

Timeframe: Baseline

Population: Data was only collected from participants who answered the question.

Trust in national government COVID-19 information was assessed using the survey question: "What level of trust do you have in the information about COVID-19 from your national government?. Responses were reported on a 5 point likert scale ranging from 1 (none at all) to 5(a great deal), a higher score indicating greater trust.
