US-Mexico binational COVID-19 cases in southern California border counties, California, February-June 2020.

Background: COVID-19 has had a significant public health impact on both the United States and Mexico. Cross-border mobility between southern California and Mexico raises questions of transmission trends between these jurisdictions. The objective of this project was to describe binational cases amongst California US-Mexico border county COVID-19 cases and compare incidence trends to cross-border Mexico jurisdictions. Methods: Interview data from persons with confirmed SARS-CoV-2 infections in San Diego County, CA and Imperial County, CA from February to June 2020 were reviewed for binational cases; demographics and connection to COVID-19 outbreaks were assessed. Graphs of COVID-19 incidence in San Diego County and Imperial County were compared to incidence graphs in cross-border Mexico jurisdictions of Tijuana and Mexicali. Results: Persons with COVID-19 and a binational case were older, more likely to be Hispanic, and reside in a border ZIP code than those without. Binational cases were a small proportion and tracked with overall cases during the study period. Conclusions: Binational cases had different trends than non-binational cases of SARS-CoV-2 in San Diego and Imperial counties from February to June 2020. Findings could inform SARS-CoV-2 mitigation strategies specific to the US-Mexico land border, particularly recommendations regarding cross-border land travel.

CDC-Supported National Network of Farmworker-Serving Organizations to Mitigate COVID-19.

The Centers for Disease Control and Prevention has partnered with the National Center for Farmworker Health to respond to the impact of COVID-19 on US farmworker communities. Immigrant farmworkers are often isolated from public health infrastructure. This partnership built the capacity of a national network of organizations to connect farmworkers to COVID-19 education and vaccinations in 20 states through training and resource sharing. The partnership funded 194 network member staff, trained 1130 individuals, and supported COVID-19 outreach to more than 600 000 farmworkers.

Coronavirus Disease 2019 (COVID-19) Vaccination Coverage, Intentions, Attitudes, and Barriers by Race/Ethnicity, Language of Interview, and Nativity-National Immunization Survey Adult COVID Module, 22 April 2021-29 January 2022.

The National Immunization Survey Adult COVID Module used a random-digit-dialed phone survey during 22 April 2021-29 January 2022 to quantify coronavirus disease 2019 (COVID-19) vaccination, intent, attitudes, and barriers by detailed race/ethnicity, interview language, and nativity. Foreign-born respondents overall and within racial/ethnic categories had higher vaccination coverage (80.9%), higher intent to be vaccinated (4.2%), and lower hesitancy toward COVID-19 vaccination (6.0%) than US-born respondents (72.6%, 2.9%, and 15.8%, respectively). Vaccination coverage was significantly lower for certain subcategories of national origin or heritage (eg, Jamaican [68.6%], Haitian [60.7%], Somali [49.0%] in weighted estimates). Respondents interviewed in Spanish had lower vaccination coverage than interviewees in English but higher intent to be vaccinated and lower reluctance. Collection and analysis of nativity, detailed race/ethnicity and language information allow identification of disparities among racial/ethnic subgroups. Vaccination programs could use such information to implement culturally and linguistically appropriate focused interventions among communities with lower vaccination coverage.

Influenza vaccination coverage among adults by nativity, race/ethnicity, citizenship, and language of the interview - United States, 2012-2013 through 2017-2018 influenza seasons.

BACKGROUND: Approximately 20,000 people died from influenza in the US in the 2019-2020 season. The best way to prevent influenza is to receive the influenza vaccine. Persons who are foreign-born experience disparities in access to, and utilization of, preventative healthcare, including vaccination. METHODS: National Health Interview Survey data were analyzed to assess differences in influenza vaccination coverage during the 2012-2013 through 2017-2018 influenza seasons among adults by nativity, citizenship status of foreign-born persons, race/ethnicity, and language of the interview. RESULTS: Influenza vaccination coverage increased significantly during the study period for US-born adults but did not change significantly among foreign-born racial/ethnic groups except for increases among foreign-born Hispanic adults. Coverage for foreign-born adults, those who completed an interview in a non-English language, and non-US citizens, had lower vaccination coverage during most influenza seasons studied, compared with US-born, English-interviewed, and US-citizen adults, respectively. CONCLUSIONS: Strategies to improve influenza vaccination uptake must consider foreign-born adults as an underserved population in need of focused, culturally-tailored outreach. Achieving high influenza vaccination coverage among the foreign-born population will help reduce illness among the essential workforce, achieve national vaccination goals, and reduce racial and ethnic disparities in vaccination coverage in the US.
