Objective: COVID-19 and associated morbidity and mortality has disproportionately affected minoritized populations. The epidemiology of spread of COVID-19 among pregnant women by race/ethnicity is not well described. Using data from a large healthcare system in California, we estimated prevalence and spread during pregnancy and recommend a vaccination approach based on minimizing adverse outcomes. Methods: Patients delivering at Sutter Health are tested (molecular) for COVID-19. These results were combined with antibody test results, using samples drawn at delivery. For each racial/ethnic group, we estimated prevalence of COVID-19, using logistic regression to adjust for known sociodemographic and comorbid risk factors. Testing for immunoglobulin G and immunoglobulin M provided insight into timing of infections. Results: Among 17,446 women delivering May–December, 460 (2.6%) tested positive (molecular). Hispanic women were at 2.6 times the odds of being actively infected as White women (odds ratio = 2.6, 95% confidence interval = 2.0–3.3). August and December were the highest risk periods for active infection (odds ratio = 3.5, 95% confidence interval = 2.1–5.7 and odds ratio = 6.1, 95% confidence interval = 3.8–9.9, compared with May, respectively). Among 4500 women delivering October–December, 425 (9.4%) had positive molecular or antibody tests, ranging from 4.0% (Asian) to 15.7% (Hispanic). Adjusting for covariables, compared with White patients, odds of infection was similar for Black and Asian patients, with Hispanic at 2.4 (1.8–3.3) times the odds. Conclusion: COVID-19 prevalence was higher among Hispanic women at delivery and in the last trimester than their White counterparts. Higher rates in Black patients are explained by other risk factors. Resources should be directed to increase vaccination rates among Hispanic women in early stages of pregnancy.

Language diversity is increasing in the United States. This growth has implications for language preference, cost, quality, and client outcomes in health services settings. However, language diversity among medical and allied health professionals is lacking. Education pipeline programs are a mechanism to prepare bi-and multi-lingual diverse students to enter health careers. The Community of Bilingual English-Spanish Speakers Exploring Issues in Science and Health (CBESS) is one such program. Through peer mentorship from Leadership Trainees (LT), and a multicomponent 17-month education curriculum, CBESS was designed to increase interest in STEM careers among English-Spanish bilingual high school youth. In 2020, the COVID-19 pandemic interrupted high school students' education and forced programs to innovate. CBESS was no exception. The most significant modifications were to a) expectations of SRs for a successful Summer Virtual Research Program (SVRP), b) LT roles, and c) scope and delivery of summer science content. A preliminary evaluation was conducted from data collected through pre-post surveys, process data, and focus groups. Among the outcomes were a significant increase in science knowledge among SVRP youth participants as well as no significant differences between cohort 1 and 2 suggesting that changes did not impede program goals. LTs highlighted skills needed and role of mentors. Adaptations were successful and will continue with the 2021 cohort.
