Objectives: Screening tools in which participants self-report sexual behaviors can identify people at risk of HIV acquisition for enrollment in preexposure prophylaxis (PrEP). We compared enrollment outcomes (ie, receiving PrEP vs being excluded by a counselor or declining PrEP) in Mexico's PrEP demonstration project and evaluated the validity of a 4-criteria PrEP eligibility tool in which participants self-reported risk behavior-having condomless anal sex, transactional sex, a partner living with HIV, or a sexually transmitted infection-as compared with PrEP eligibility assessed by a counselor.

Methods: We recruited men who have sex with men and transwomen who were offered PrEP services in Mexico. We characterized participants according to enrollment outcome and identified underlying factors through logistic regression analyses. We calculated the sensitivity and specificity of the self-reported risk criteria, using the counselor's risk assessment as the point of reference.

Results: Of 2460 participants, 2323 (94%) had risk criteria of HIV acquisition according to the 4-criteria tool; 1701 (73%) received PrEP, 247 (11%) were excluded by a counselor, and 351 (15%) declined PrEP despite being considered eligible by the counselor. Participants who were excluded or who declined PrEP were less likely to report HIV risk behaviors than those who received PrEP, and participants who declined PrEP were more likely to be transwomen (vs men who have sex with men) and aged ≤25 years (vs >25 y). The 4-criteria risk tool had high sensitivity (98.6%) and low specificity (29.8%).

Conclusion: The screening tool identified most participants at risk of HIV acquisition, but counselors' assessment helped refine the decision for enrollment in PrEP by excluding those with low risk. Public health strategies are needed to enhance enrollment in PrEP among some groups.

Objectives: Evidence is limited on differences in cesarean rates for nulliparous, term, singleton, vertex (NTSV) births across racial and ethnic groups at the national and state level during the COVID-19 pandemic. We assessed changes in levels and trends of NTSV cesarean rates before and after stay-at-home orders (SAHOs) were implemented in the United States (1) overall, (2) by racial and ethnic groups, and (3) by 50 US states from January 2017 through December 2021.

Methods: We used birth certificate data from 2017 through 2021, restricted to hospital births, to calculate monthly NTSV cesarean rates for the United States and for racial and ethnic groups and to calculate quarterly NTSV cesarean rates for the 50 states. We used interrupted time-series analysis to measure changes in NTSV cesarean rates before and after implementation of SAHOs (March 1 through May 31, 2020).

Results: Of 6 022 552 NTSV hospital births, 1 579 645 (26.2%) were cesarean births. Before implementation of SAHOs, NTSV cesarean rates were declining in the United States overall; were declining among births to non-Hispanic Asian, non-Hispanic Black, Hispanic, and non-Hispanic White women; and were declining in 6 states. During the first month of implementation of SAHOs in May 2020, monthly NTSV rates increased in the United States by 0.55%. Monthly NTSV rates increased by 1.20% among non-Hispanic Black women, 0.90% among Hispanic women, and 0.28% among non-Hispanic White women; quarterly NTSV rates increased in 6 states.

Conclusion: In addition to emergency preparedness planning, hospital monitoring, and reporting of NTSV cesarean rates to increase provider awareness, reallocation and prioritization of resources may help to identify potential strains on health care systems during public health emergencies such as the COVID-19 pandemic.

Objectives: Although enteric disease case interviews are critical for control measures and education, not all case-patients are interviewed. We evaluated systematic differences between people with an enteric disease in Colorado who were and were not interviewed to identify ways to increase response rates and reduce biases in the surveillance data used to guide public health interventions.

Methods: We obtained data from the Colorado Electronic Disease Reporting System from March 1, 2017, through December 31, 2019. Among case-patients not interviewed and interviewed, we used univariate analyses to describe sociodemographic characteristics, timing of contact attempts, and effect of additional funding.

Results: As compared with case-patients who were interviewed, case-patients who were not interviewed were significantly more likely to be aged 18 to 39 years (35.7% vs 31.7%; P < .001); identify as male, Hispanic, or Black; be experiencing homelessness or hospitalization; reside in rural/frontier areas or an institution; or live in areas with lower levels of education, life expectancy, and income. Time to first contact attempt was longer for case-patients who were not interviewed than for those who were (mean days from specimen collection to first contact attempt, 9.8 vs 6.8; P < .001). Residing in a jurisdiction with additional funding for interviewing was associated with increased interview rates (87.7% vs 68.8%) and timeliness of public health report and first contact attempt (2.3 vs 4.4 days; P < .001).

Conclusion: Findings can guide efforts to improve response rates in groups least likely to be interviewed, resulting in reduced biases in surveillance data, better disease mitigation, and increased efficiency in case investigations. Timeliness of case interviews and additional funding to conduct case investigations were factors in increasing response rates.

We critically reviewed the motivations, processes, and implementation methods underlying a faculty-driven diversity, equity, and inclusion (DEI) curriculum self-reflection project in the Rutgers School of Public Health. This case study offers guidance on a curriculum self-reflection tool that was developed through the school's Curriculum Committee to promote DEI throughout the school's curricula. We review the key steps in this process and the unique aspects of developing and implementing such evaluations within higher education. The study draws on faculty experience, was informed by students and staff within the Curriculum Committee, and builds on existing knowledge and tools. A flexible 6-step framework-including guiding principles and strategic approaches to planning, developing, and implementing a DEI curriculum self-assessment-is provided to assist instructors, curriculum committees, DEI groups, and academic leaders at schools of public health interested in refining their courses and curricula. Academic units experience contextual challenges, and while each is at a different stage in curriculum reform, our findings provide lessons about integrating the assessment of DEI in school curriculum in a systematic and iterative way. Our approach can be applied to diverse academic settings, including those experiencing similar implementation challenges.

Objectives: The Laboratory Response Network (LRN) consists of US and international laboratories that respond to public health emergencies, such as biothreats. We used a qualitative approach to assess the successes and challenges of the LRN during the initial 10 weeks of the 2022 mpox outbreak (May 17-July 31, 2022).

Methods: We conducted 9 unstructured interviews, which included 3 interviews with subject matter experts from the Centers for Disease Control and Prevention (CDC) and 6 interviews with state and local public health laboratories and epidemiologists and Association of Public Health Laboratories (APHL) staff. We asked guiding questions on investments in preparedness, successes, and challenges during the initial mpox response and asked for suggestions to improve future LRN responses to infectious disease outbreaks. We also reviewed data from 2 contemporaneous APHL surveys conducted in June and July 2022 in 84 LRN public health laboratories.

Results: Notable successes included availability of an assay that had received clearance from the US Food and Drug Administration (FDA) for testing orthopoxviruses (non-variola Orthopoxvirus [NVO] assay) and a trained workforce; strong relationships among FDA, CDC, and the LRN; and strong communications between LRN laboratories and CDC. Challenges included variability among LRN laboratories in self-reported testing capacity, barriers to accessing the NVO assay for health care providers, and gaps in LRN function during surges of testing needs.

Conclusions: The LRN system plays an essential role in the response to emerging infectious disease outbreaks in the United States. Lessons learned from the LRN's initial response to the mpox outbreak can help guide improvements to better position the LRN for future responses, including continued engagement with health care providers, commercial laboratories, and laboratories in health care settings.

Objective: We conducted a national US study of SARS-CoV-2 seroprevalence by Social Vulnerability Index (SVI) that included pediatric data and compared the Delta and Omicron periods during the COVID-19 pandemic. The objective of the current study was to assess the association between SVI and seroprevalence of infection-induced SARS-CoV-2 antibodies by period (Delta vs Omicron) and age group.

Methods: We used results of infection-induced SARS-CoV-2 antibody assays of clinical sera specimens (N = 406 469) from 50 US states from September 2021 through February 2022 to estimate seroprevalence overall and by county SVI tercile. Bivariate analyses and multilevel logistic regression models assessed the association of seropositivity with SVI and its themes by age group (0-17, ≥18 y) and period (Delta: September-November 2021; Omicron: December 2021-February 2022).

Results: Aggregate infection-induced SARS-CoV-2 antibody seroprevalence increased at all 3 SVI levels; it ranged from 25.8% to 33.5% in September 2021 and from 53.1% to 63.5% in February 2022. Of the 4 SVI themes, socioeconomic status had the strongest association with seroprevalence. During the Delta period, we found significantly more infections per reported case among people living in a county with high SVI (odds ratio [OR] = 2.76; 95% CI, 2.31-3.21) than in a county with low SVI (OR = 1.65; 95% CI, 1.33-1.97); we found no significant difference during the Omicron period. Otherwise, findings were consistent across subanalyses by age group and period.

Conclusions: Among both children and adults, and during both the Delta and Omicron periods, counties with high SVI had significantly higher SARS-CoV-2 antibody seroprevalence than counties with low SVI did. These disparities reinforce SVI's value in identifying communities that need tailored prevention efforts during public health emergencies and resources to recover from their effects.

In the United States, persistent health disparities and preexisting gaps in local public health infrastructure led to disproportionate effects of COVID-19 across populations at high risk of COVID-19-related morbidity and mortality. In Pima County, Arizona, equity-centered local government engagement and policy action, multipronged community-based responses, and expansion of historically underfunded local public health infrastructure improved equitable outcomes and addressed multiple systemic factors. This case study examined Pima County's 3-pronged public health response to COVID-19 using an equity-based approach. As a result, COVID-19 was the third leading cause of death in Pima County in 2021, compared with being the leading cause of death in Arizona. Strong political support from local elected officials created the authorizing environment for the Pima County Health Department to advance health equity. Passage of a resolution in December 2020, which framed the racial and ethnic health and socioeconomic inequities as a public health crisis, supported innovation and fostered the creation of an Office of Health Equity, a public health policy program, and a data and informatics program. New structures for community engagement were formed, including an ethics committee and a community advisory committee, to ensure a formalized process for community participation in public health actions, during and after the pandemic response. Key lessons learned included (1) the importance of local government support, codified to allow implementation of creative strategies; (2) opening avenues for community voice and engagement in planning and implementation to respond in areas of greatest need; and (3) having flexible funding to sustain an equitable response.

Childhood psychosocial experiences can have a lifelong effect on health. These experiences can be measured together as positive and adverse childhood experiences or individually as positive childhood experiences (PCEs) or adverse childhood experiences. Most research on PCEs has focused on how PCEs promote health outcomes. However, limited research has been conducted on the prevalence of PCEs among adolescents in local areas served by public health departments. The St. Joseph County Department of Health developed a study to test the feasibility of surveillance of PCEs through local public health departments and to establish a prevalence for PCE exposure among a population of urban public-school students in Indiana. We conducted a survey in spring 2022 that collected demographic information on students at 2 high schools and 1 middle school and assessed exposure to PCEs. We assessed prevalence of PCEs on a 5-point Likert scale (0 = never, 1 = rarely, 2 = sometimes, 3 = usually, 4 = always). PCE scores were grouped into low (0-2), medium (3-5), and high (6 or 7). The prevalence of individual PCE items ranged from 35.6% to 86.8%. Among 798 respondents, 189 (23.7%) reported low PCE scores, 396 (49.6%) reported medium scores, and 213 (26.7%) reported high scores. This research demonstrates the feasibility of school-based PCE surveillance and establishes a baseline prevalence of PCE exposure among a population of middle and high school students. These methods are applicable to different contexts and can provide both local health departments and school systems with a new tool to address adverse childhood experiences.

Objectives: The 12-month vaccination campaign ¡Ándale! ¿Qué Esperas? was launched to increase COVID-19 vaccination rates in Latinx populations in California by expanding community outreach. The objectives of this evaluation were to (1) determine predictors of vaccination rates and (2) identify barriers to vaccination and potential solutions.

Methods: Five community partners in California serving Latinx populations with high social vulnerability participated in the ¡Ándale! ¿Qué Esperas? campaign. Community health workers were hired to deliver outreach (virtual, one-on-one, group based, and information dissemination), vaccinations, and supportive services. We collected data on outreach strategy used (method and location), number of vaccinations provided and reasons for delay, and number of times that supportive services were provided. We used regression models to assess significant predictors of vaccinations and supportive services.

Results: Community health workers (N = 146) hired from June 1, 2021, through May 31, 2022, performed outreach engagements (n = 6297) and supportive services (n = 313 796), resulting in 130 413 vaccinations and 28 660 vaccine appointments. The number of vaccinations administered was significantly higher at events in which supportive services were provided versus not provided (coefficient = 34.02; 95% CI, 3.34-64.68; P = .03). The odds ratio of supportive services was 3.67 (95% CI, 1.76-7.55) during virtual outreach and 2.95 (95% CI, 2.37-3.69) during one-on-one outreach (P < .001 for both) as compared with information dissemination encounters. Vaccination concerns were reported among 55.0% of vaccinated survey respondents (67.7%, vaccine confidence; 51.7%, access).

Conclusions: Supportive services facilitate vaccinations, ease transportation and time barriers, and instill confidence among working-class racial and ethnic minority populations.

After a tumultuous 3 years of pandemic-, political-, and race-related unrest in the United States, the public is demanding accountability to communities of color (defined here as American Indian/Alaska Native, Asian, Black, Native Hawaiian/Pacific Islander, and Hispanic people) to rectify historic and contemporary injustices that perpetuate health inequities and threaten public health. Structural racism pervades all major societal systems and exposes people to detrimental social determinants of health. Disrupting structural racism within public health systems is essential to advancing health equity and requires organized partnerships between health departments and community leaders. As those who are most affected by structural racism, communities of color are the experts in knowing its impacts. This case study describes the King County Pandemic and Racism Community Advisory Group (PARCAG) and its use of an innovative accountability tool. The tool facilitated institutional transparency and accountability in the adoption of community recommendations. PARCAG was influential in shaping Public Health-Seattle & King County's COVID-19 and antiracism work, with 66 of 75 (88%) recommendations adopted partially or fully. For example, a fully adopted recommendation in May 2020 was to report King County COVID-19 case data by race and ethnicity, and a partially adopted recommendation was to translate COVID-19 information into additional languages. PARCAG members were recruited from a 2019 advisory board on Census 2020 and were adept at shifting to advising on COVID-19 and equitable practices and policies. Organizations that have made declarations that racism is a public health crisis should center the experiences, expertise, and leadership of communities of color in accountable ways when developing and implementing strategies to disrupt and repair the effects of structural racism and efforts to promote and protect public health.
