Study Description: This project evaluated community-engaged approaches to improving access and uptake of COVID-19 testing among majority Latinx communities in Northern California, and to understanding local epidemiology and factors driving the stark ethnic disparities observed in COVID-19 case rates. In Aim 1, the project evaluated implementation of a Latino Task Force (LTF) collaborative network across 3 counties in California (Marin, Merced and San Francisco), adapted from San Francisco's LTF model to promote locally-adapted COVID-19 test and respond initiatives in two majority-Latinx communities: one suburban (Marin) and one rural (Merced). In Aim 2, the project determined the population-level prevalence of active (PCR+) SARS-CoV-2 infection, most at-risk subgroups, and attitudes and preferences of community members regarding COVID-19 testing services during baseline mass testing campaigns at the Marin and Merced sites. The campaigns offered testing to all community residents regardless of symptoms at easily accessible venues, implemented in partnership with each site's LTF. In Aim 3 (pending NIH approval for change in scope), the study evaluated implementation of community-responsive COVID-19 testing strategies, delivered by local community health workers (promotoras) and tailored to the needs of the two study communities post-COVID-19 vaccine scale-up in Northern California.
