Marginalized communities were disproportionately affected by the COVID-19 pandemic with increased cases, hospitalizations, and deaths. As the County COVID-19 testing lead, I worked to ensure equitable access to COVID-19 testing in marginalized communities across Los Angeles County. We partnered with the State, Cities and private partners to expand countywide testing capacity, used data to allocate COVID-19 community testing resources to the most marginalized and impacted communities, engaged trusted messengers to get accurate information out to these populations, and engaged our expert community-based organizations and churches to perform outreach, navigation, and testing. Through this effort we reduced disparities in COVID-19 testing access between high and low risk communities by Health People Index indicator through the course of the pandemic.
