Measles outbreak under the Leaning Tower of Pisa in Italy

Abstract Background Measles cases in Italy (58,9 mln population) were 8 in 2021, 15 in 2022 and 43 in 2023. Between January and April 2024 there were 213 cases in Italy, with higher incidence in children. Pisa Local Public Health Department (201073 population) experienced a measles outbreak in the same period. Methods Cases were classified according to Decision (EU) 2018/945. A bidirectional tracing (backward and forward) was conducted to identify transmission chain and contacts of cases. Immunization status was checked on Regional Vaccination Registry. Results 33 suspected measles cases were notified in Pisa between 21st January and 17th April 2024: 16 by General Practitioners and 17 by Hospital Emergency Room. Additionally, 1 undiagnosed case was found during the epidemiological investigation. 2 notifications were withdrawn by General Practitioner because of lack of the diagnostic criteria. Laboratory analysis confirmed 24 cases. Last confirmed case occurred on 23rd February, while not confirmed cases occurred mostly in the last part of the period (6 in a row from 3rd March to 17th April), suggesting an infodemic effect. Women were more affected than men (17 vs. 7). Except for 2 babies (9 months and 1 year old age), the outbreak affected young adults with a mean age of 40 yo. Hospitalization rate was 37,5%. The first 5 unrelated cases occurred between 19th and 21st January. A second wave involved 13 people, 12 of them were related to a single case. Transmission occurred in Emergency Room (7), in a mall (1) and in the neighborhood (4). A third wave involved 4 cases (family contacts). 2 cases were imported from Sicily and Spain. All cases were unvaccinated, 2 were migrants. Around 950 contacts were traced. Conclusions In Pisa, high vaccination coverage of children < 2years of age (≥95%) protected school population and cases to spread, but there are pockets of unvaccinated adults which could allow measles circulation. Key messages • An effective public health response is required to contrast increasing measles cases in EU/EE countries. • As recommended by ECDC, public health services need to close immunity gaps, addressing catch-up actions towards adults and vulnerable groups as migrants.

Respiratory Isolation for Tuberculosis: A Historical Perspective.

Although tuberculosis is an ancient disease, recognition of its airborne route of transmission, with implications for respiratory isolation, is only relatively recent. Since the time of Hippocrates, the dogma among health practitioners was that the disease was hereditary or that it could be contracted by inhaling "miasma", or corrupted air. Consequently, isolation of patients was not routine practice, and, in fact, patients with scrofula (morbus regius, or "king's evil) sought to be cured by the "royal touch" throughout the middle ages. The sanatorium, which emerged in the mid-19th century, initially served as a place of healing, where patients could receive the appropriate diet, rest therapy, graduated exercise, and abundant fresh air. Major scientific breakthroughs, including Robert Koch's 1882 discovery of the tubercle bacillus as the disease's etiological agent and early 20th century experimental evidence that the organism could be transmitted via expectorated droplet nuclei, helped to reinforce the important public health role of sanatoria and tuberculosis hospitals in preventing disease transmission through isolation. The advent of highly efficacious and oral antitubercular regimens in the mid-20th century and the concurrent declining incidence of the disease contributed to the closure of tuberculosis sanatoria and hospitals in the US and western Europe. Over the past several decades, tuberculosis treatment in the US has been conducted in the outpatient setting under the supervision of local public health departments. Patients receiving treatment are required to remain in respiratory isolation in the home until they are deemed noninfectious based on multiple sputum samples. This historical review demonstrates that despite changing medical knowledge, drug therapies, and social conditions over time, the role of isolation remains an important topic of debate in the treatment of patients with pulmonary tuberculosis.

The epidemiological and infectious characteristics of novel types of Coxiella burnetii co-infected with Coxiella-like microorganisms from Xuyi County, Jiangsu province, China

Coxiella burnetii (C. burnetii) is the causative agent of Q fever, a type of zoonoses withwidespread distribution. In 2019, a case of Q fever was diagnosed by metagenomic next-generation sequencing (mNGS) method in Xuyi County (Jiangsu province, China). The seroprevalence of previous fever patients and the molecular epidemiology of Coxiella in wild hedgehogs and harbouring ticks around the confirmed patient were detected to reveal the genetic characteristics and pathogenicity of the Coxiella strains. Four of the 90 serum samples (4.44%) were positive for specific C. burnetii IgM antibody, suggesting that local humans are at risk of Q fever. The positive rates of C. burnetii in hedgehogs and ticks were 21.9% (7/32) and 70.5% (122/173), respectively. At least 3 strains of Coxiella were found prevalent in the investigated area, including one new genotype of pathogenic C. burnetii (XYHT29) and two non-pathogenic Coxiella-like organisms (XYHT19 and XYHT3). XYHT29 carried by ticks and wild hedgehogs successfully infected mice, imposing a potential threat to local humans. XYHT19, a novel Coxiella-like microorganism, was first discovered in the world to co-infect with C. burnetii in Haemaphysalis flava. The study provided significant epidemic information that could be used for prevention and control strategies against Q fever for local public health departments and medical institutions.

Developing Infectious Disease Outbreak Emergency Communications for Populations With Limited English Proficiency: Insights to Sustain Collaborations Between Local Health Departments and Community-Based Organizations.

State and local public health departments (LHDs) are encouraged to collaborate with community-based organizations (CBOs) to enhance communication and promote protective practices with communities made vulnerable during emergencies, but there is little evidence-based understanding of practical approaches to fostering collaboration in this context. This research focuses on how collaboration enhances LHD capacity for effective communication for people with limited English proficiency (LEP) during infectious disease outbreaks specifically and strategies to facilitate productive LHD-CBO collaboration. Qualitative, telephone interviews, conducted March-October 2021. Rural and urban jurisdictions with Chinese-speaking or Spanish-speaking populations across the United States. 36 LHD and 31 CBO staff working on outreach to Chinese and Spanish speakers during COVID-19. Interviews were audio-recorded, transcribed verbatim, and analyzed using a team-based, codebook approach to thematic analysis. During COVID-19, CBOs extended LHD capacity to develop and disseminate effective communication, meaning communication that is rapidly in-language, culturally resonant, locally relevant, and trusted. Practical strategies to enable and sustain effective collaboration were needed to address operational dimensions (eg, material and administrative) and relational dimensions (eg, promoting trust and respect). Policies and financing to support LHD-CBO collaborations are critical to improving communication with people with LEP and addressing long-standing inequities in outcomes during outbreaks.

Pipeline emergency preparedness in Nebraska: Identifying interagency preparedness gaps and proposing solutions.

In Nebraska, there are over 28,000 miles of pipelines that carry various materials, which could impact human health and the natural environment in the event of a leak or spill. Nebraska is heavily reliant on its expansive groundwater supply from the large High Plains aquifer system as well as smaller secondary aquifers. Eighty-eight percent of Nebraska's population utilizes groundwater for personal use, and the state's agricultural sector depends on it for irrigation and livestock care. The ongoing challenges facing the implementation of the proposed Keystone XL pipeline system inspired re-searchers to examine the current state of pipeline emergency preparedness in Nebraska. To do this, a pipeline emergency preparedness workshop was held in November 2021 in Norfolk, Nebraska. Conference participants in-cluded county- and regional-level leadership, local public health departments, tribal representatives, and other organizations. Pipeline emergency responders and other stakeholders were invited to listen to plenary presenta-tions about inland oil spill responses and the current state of Nebraska pipelines and to participate in a facilitated discussion identifying pipeline response challenges and potential solutions. Through a facilitated discussion process, participants identified six general response challenge categories and 24 potential solutions. From those 24 solutions, three were selected as easily implementable solutions-increased joint/coordinated planning, increased pipeline emergency exercising, and increased pipeline emergency train-ing/education. Implementing this work will assist in reducing health risks associated with potential spills.

Challenges and Opportunities for Participatory Evaluation of Local Public Health Efforts to Address Structural Racism and Advance Health Equity

This report describes the process of conducting a participatory evaluation of a local public health department and community partners’ joint efforts to address structural racism and advance health equity in Chicago, Illinois. The participatory evaluation is guided by a multi-partner advisory group composed of academic researchers and research assistants at a local public university; leadership and frontline staff at the local public health department; and individuals employed through local community-based organizations. This report details three key action points in the participatory evaluation process, highlighting the challenges and opportunities that arise while evaluating health equity interventions aimed at institutional and structural change. Insights gleaned from this process can inform ongoing and future participatory evaluation efforts and contribute to the establishment of best practices for partnering across institutions to reshape systems and power relationships to advance health equity.

982-P: The Dexcom Community Glucose Monitoring Project for People with Type 2 Diabetes—One-Year Outcomes

Background & Objective: Access to CGM for people with type 2 diabetes (T2D) remains limited, especially for those treated in the primary care setting. The objective of this study, a collaboration between a primary care practice and the local public health department, was to evaluate the glycemic impact of CGM access on adults with T2D. Methods: CGM systems (Dexcom G6 and G7) were provided to eligible participants with T2D who were ≥18 years of age, CGM-naïve, and did not have health insurance coverage for CGM. Outcomes included changes in A1C and CGM metrics from baseline to one year. Results: Participants (n=177) were (mean ± SD) 59.1 ± 12.0 years, 41.2% female, BMI 35.5 ± 8.5, duration of diabetes 11.1 ± 9.3 years. After one year, A1C decreased from 9.4% ± 1.6 to 7.1% ± 1.3 (-2.3% ± 1.9, p<0.001). The proportion of participants meeting the ADA target of A1C <7.0% increased from n=1 (0.6%) at baseline to n=91 (51.4%) at one year. Those meeting the HEDIS target of A1C <8.0% increased from 19.2% at baseline to 85.9% at one year. CGM outcomes (n=109) after near-continuous use included an increase in TIR of 9.9% ± 29.4 (p<0.001) and a large increase in TITR (p<0.001, Table). Conclusion: Self-guided use of CGM by primary care patients with T2D for one year was associated with clinically meaningful improvements in A1C and TIR. Disclosure T.

Leveraging Science to Advance Health Equity: Preliminary Considerations for Implementing Health Equity Science at State and Local Health Departments.

In 2021, the Centers for Disease Control and Prevention (CDC) launched CORE, an agency-wide strategy to embed health equity as a foundational component across all areas of the agency's work. The CDC established a definition of health equity science (HES) and principles to guide the development, implementation, dissemination, and use of the HES framework to move beyond documenting inequities to investigating root causes and promoting actionable approaches to eliminate health inequities. The HES framework may be used by state and local health departments to advance health equity efforts in their jurisdictions. Identify implementation considerations and opportunities for providing technical assistance and support to state and local public health departments in advancing HES. A series of implementation consultations and multi-jurisdictional facilitated discussions were held with state and local health departments and community partners in 5 states to gather feedback on the current efforts, opportunities, and support needs to advance HES at the state and local levels. The information shared during these activities was analyzed using inductive and deductive methods, validated with partners, and summarized into themes and HES implementation considerations. Five themes emerged regarding current efforts, opportunities, and support needed to implement HES at state and local health departments. These themes included the following criteria: (1) enhancing the existing health equity evidence base; (2) addressing interdisciplinary public health practice and data needs; (3) recognizing the value of qualitative data; (4) evaluating health equity programs and policies; and (5) including impacted communities in the full life cycle of health equity efforts. Within these themes, we identified HES implementation considerations, which may be leveraged to inform future efforts to advance HES at the state and local levels. Health equity efforts at state and local health departments may be strengthened by leveraging the HES framework and implementation considerations.

Prospective Spatiotemporal Cluster Detection Using SaTScan: Tutorial for Designing and Fine-Tuning a System to Detect Reportable Communicable Disease Outbreaks.

Staff at public health departments have few training materials to learn how to design and fine-tune systems to quickly detect acute, localized, community-acquired outbreaks of infectious diseases. Since 2014, the Bureau of Communicable Disease at the New York City Department of Health and Mental Hygiene has analyzed reportable communicable diseases daily using SaTScan. SaTScan is a free software that analyzes data using scan statistics, which can detect increasing disease activity without a priori specification of temporal period, geographic location, or size. The Bureau of Communicable Disease's systems have quickly detected outbreaks of salmonellosis, legionellosis, shigellosis, and COVID-19. This tutorial details system design considerations, including geographic and temporal data aggregation, study period length, inclusion criteria, whether to account for population size, network location file setup to account for natural boundaries, probability model (eg, space-time permutation), day-of-week effects, minimum and maximum spatial and temporal cluster sizes, secondary cluster reporting criteria, signaling criteria, and distinguishing new clusters versus ongoing clusters with additional events. We illustrate how to support health equity by minimizing analytic exclusions of patients with reportable diseases (eg, persons experiencing homelessness who are unsheltered) and accounting for purely spatial patterns, such as adjusting nonparametrically for areas with lower access to care and testing for reportable diseases. We describe how to fine-tune the system when the detected clusters are too large to be of interest or when signals of clusters are delayed, missed, too numerous, or false. We demonstrate low-code techniques for automating analyses and interpreting results through built-in features on the user interface (eg, patient line lists, temporal graphs, and dynamic maps), which became newly available with the July 2022 release of SaTScan version 10.1. This tutorial is the first comprehensive resource for health department staff to design and maintain a reportable communicable disease outbreak detection system using SaTScan to catalyze field investigations as well as develop intuition for interpreting results and fine-tuning the system. While our practical experience is limited to monitoring certain reportable diseases in a dense, urban area, we believe that most recommendations are generalizable to other jurisdictions in the United States and internationally. Additional analytic technical support for detecting outbreaks would benefit state, tribal, local, and territorial public health departments and the populations they serve.

Overdose prevention activities led by local public health departments, 2019–2023

BackgroundDrug overdose deaths in the United States increased to historic levels in recent years, with provisional estimates indicating more than 111,000 deaths in the 12 months ending July 2023. In 2019, the Centers for Disease Control and Prevention’s Division of Overdose Prevention in collaboration with the National Association of City and County Health Officials, funded local health departments (LHDs) to work on overdose prevention activities. This paper aims to: 1) describe the overdose prevention activities that LHDs implemented during the four eighteen-month funding cycles; 2) identify programmatic successes and areas of opportunity for LHDs to consider when implementing future overdose prevention activities; and to 3) inform policy considerations and future overdose prevention programming at the local level.MethodsWe used programmatic data to identify overdose prevention activities implemented by 45 LHDs. Activities were double-coded according to the social-ecological model and the U.S. Department of Health and Human Services Overdose Prevention Strategies and Guiding Principles. We analyzed final codes to identify distribution and overlap of the Strategies and Guiding Principles across the social ecological model co-occurrences.ResultsApproximately 55.9% (n=123) of the 220 overdose prevention activities that were coded took place at the community level, 32.3% (n=71) at the individual level, 8.6% (n=19) at the relationship level, and 3.2% (n=7) at the policy level. Most of the activities were coded as coordination, collaboration, and integration (n=52, 23.6%), harm reduction (n=51, 23.1%), data and evidence (n=47, 21.4%) or reducing stigma (n=24, 10.9%). Few activities were related to primary prevention (n=14, 6.4%), equity (n=14, 6.4%), recovery support (n=11, 5.0%), and evidence-based treatment (n=7, 3.2%).ConclusionsLocalities have primarily implemented activities focused on the community and individual levels, with most of these centered around coordination, collaboration, and integration; harm reduction; or data and evidence. This study identified gaps in overdose prevention for LHDs related to treatment and health equity and that more interventions should be implemented at the relationship and policy levels. Continuing these efforts is important as LHDs explore opportunities to enhance and expand their work in various strategy areas across the social ecology. Findings from this study may be used to inform localities as they design and implement future overdose prevention activities.

Experience of Public Health Departments in Implementation of COVID-19 Case Investigation and Contact Tracing Programs.

Case investigation and contact tracing (CI/CT) are fundamental public health efforts widely used during the COVID-19 pandemic to mitigate transmission. This study investigated how state, local, and tribal public health departments used CI/CT during the COVID-19 pandemic, including CI/CT methodology, staffing models, training and support, and efforts to identify or prioritize populations disproportionately affected by COVID-19. During March and April 2022, we conducted key informant interviews with up to 3 public health officials from 43 state, local, and tribal public health departments. From audio-recorded and transcribed interviews, we used the framework method to analyze key themes. Major adjustments to CI/CT protocols during the pandemic included (1) prioritizing populations for outreach; (2) implementing automated outreach for nonprioritized groups, particularly during COVID-19 surges; (3) discontinuing contact tracing and focusing exclusively on case investigation; and (4) adding innovations to provide additional support. Key informants also discussed the utility of having backup staffing to support overwhelmed public health departments and spoke to the difficulty in "right-sizing" the public health workforce, with COVID-19 surges leaving public health departments understaffed as case rates rose and overstaffed as case rates fell. When addressing future epidemics or outbreaks, public health officials should consider strategies that improve the effectiveness of CI/CT efforts over time, such as prioritizing populations based on disproportionate risk, implementing automated outreach, developing models that provide flexible additional staffing resources as cases rise and fall among local public health departments, incorporating demographic data in laboratory reporting, providing community connections and support, and having a system of self-notification of contacts.

Deployment of the National Notifiable Diseases Surveillance System during the 2022-23 mpox outbreak in the United States-Opportunities and challenges with case notifications during public health emergencies.

Timely case notifications following the introduction of an uncommon pathogen, such as mpox, are critical for understanding disease transmission and for developing and implementing effective mitigation strategies. When Massachusetts public health officials notified the Centers for Disease Control and Prevention (CDC) about a confirmed orthopoxvirus case on May 17, 2023, which was later confirmed as mpox at CDC, mpox was not a nationally notifiable disease. Because existing processes for new data collections through the National Notifiable Disease Surveillance System were not well suited for implementation during emergency responses at the time of the mpox outbreak, several interim notification approaches were established to capture case data. These interim approaches were successful in generating daily case counts, monitoring disease transmission, and identifying high-risk populations. However, the approaches also required several data collection approvals by the federal government and the Council for State and Territorial Epidemiologists, the use of four different case report forms, and the establishment of complex data management and validation processes involving data element mapping and record-level de-duplication steps. We summarize lessons learned from these interim approaches to inform and improve case notifications during future outbreaks. These lessons reinforce CDC's Data Modernization Initiative to work in close collaboration with state, territorial, and local public health departments to strengthen case-based surveillance prior to the next public health emergency.

Electronic Health Records for Population Health Management: Comparison of Electronic Health Record-Derived Hypertension Prevalence Measures Against Established Survey Data.

Hypertension is the most prevalent risk factor for mortality globally. Uncontrolled hypertension is associated with excess morbidity and mortality, and nearly one-half of individuals with hypertension do not have the condition under control. Data from electronic health record (EHR) systems may be useful for community hypertension surveillance, filling a gap in local public health departments' community health assessments and supporting the public health data modernization initiatives currently underway. To identify patients with hypertension, computable phenotypes are required. These phenotypes leverage available data elements-such as vitals measurements and medications-to identify patients diagnosed with hypertension. However, there are multiple methodologies for creating a phenotype, and the identification of which method most accurately reflects real-world prevalence rates is needed to support data modernization initiatives. This study sought to assess the comparability of 6 different EHR-based hypertension prevalence estimates with estimates from a national survey. Each of the prevalence estimates was created using a different computable phenotype. The overarching goal is to identify which phenotypes most closely align with nationally accepted estimations. Using the 6 different EHR-based computable phenotypes, we calculated hypertension prevalence estimates for Marion County, Indiana, for the period from 2014 to 2015. We extracted hypertension rates from the Behavioral Risk Factor Surveillance System (BRFSS) for the same period. We used the two 1-sided t test (TOST) to test equivalence between BRFSS- and EHR-based prevalence estimates. The TOST was performed at the overall level as well as stratified by age, gender, and race. Using both 80% and 90% CIs, the TOST analysis resulted in 2 computable phenotypes demonstrating rough equivalence to BRFSS estimates. Variation in performance was noted across phenotypes as well as demographics. TOST with 80% CIs demonstrated that the phenotypes had less variance compared to BRFSS estimates within subpopulations, particularly those related to racial categories. Overall, less variance occurred on phenotypes that included vitals measurements. This study demonstrates that certain EHR-derived prevalence estimates may serve as rough substitutes for population-based survey estimates. These outcomes demonstrate the importance of critically assessing which data elements to include in EHR-based computer phenotypes. Using comprehensive data sources, containing complete clinical data as well as data representative of the population, are crucial to producing robust estimates of chronic disease. As public health departments look toward data modernization activities, the EHR may serve to assist in more timely, locally representative estimates for chronic disease prevalence.

Health Promotion and Prevention of Non-Communicable Diseases by Public Health Departments in Baden-Württemberg during the COVID-19 Pandemic: Results of an Online Survey

Disease prevention and health promotion are among the core tasks of German public health services (Öffentlicher Gesundheitsdienst - ÖGD), particularly local public health departments (Gesundheitsämter). Little is known about the extent to which the departments were able to continue activities in the field of health promotion and prevention of non-communicable diseases (HPP-NCDs) during the COVID-19 pandemic. Using the example of public health departments in Baden-Württemberg (BW), we therefore investigated how much staff was available to the departments for HPP-NCDs services, how much staff was actually dedicated to HPP-NCDs during the COVID-19 pandemic, which HPP-NCDs activities were carried out during the pandemic, which were cancelled, and which should be resumed as a priority, according to the public health departments. We developed a largely standardized online questionnaire for the survey of the 38 public health departments in BW. Per department one questionnaire was to be completed. The survey took place from 9/1/2022 to 11/4/2022. The data of this explorative cross-sectional study were analyzed in a descriptive-statistical manner using SPSS, version 28. Of the 38 departments, 34 participated in the survey (89%). Departments had a mean of 2.44 full HPP-NCDs staff as planned (median 2.00; SD 1.41; range 0.20-5.00). Under pandemic conditions, a mean of 1.23 full HPP-NCDs staff were deployed (median 0.95; SD 1.24; range 0.00-4.50). Respondents gave examples of 61 HPP-NCDs activities that were conducted under pandemic conditions, and they described 69 HPP-NCDs activities that had to be cancelled. Of the latter, respondents felt that 40 should be resumed as a matter of highest priority. Analysis of the priority activities to be resumed reveals characteristic differences: e. g., resumption of structural prevention activities was viewed more frequently as a matter of hightest priority than resumption of behavioral prevention activities. During the pandemic, local public health departments in BW deployed, on average, actually only half of their full staff allocated as planned to HPP-NCDs. Comparing different categories of HPP-NCDs activities (cancelled during the pandemic) in terms of the relative frequency with which their resumption is viewed as matter of highest priority, characteristic differences can be observed. It remains an open question which conclusions can be drawn from such differences.

Leveraging Public Health and Public School Partnerships for Local Surveillance of Positive Childhood Experiences.

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.

Trichomoniasis and retesting in Durham County, North Carolina, United States, 2021 - 2022.

The Centers for Disease Control and Prevention recommends universal retesting within 3months after treatment of Trichomonas vaginalis infection given high rates of persistent infection or reinfection, or if this is not possible, within 12months following treatment. Data is lacking on how often this is actually done. We analyzed the demographic and clinical characteristics, rate of return for the recommended retesting, concordance between wet prep and nucleic acid amplification testing, and percent positivity for T. vaginalis on repeat vaginal specimens at a local public health department in Durham, North Carolina, United States. Of 193 females treated for trichomoniasis between March 1, 2021 - May 31, 2022, 83% were Black or African American and 44% between the ages of 20 and 29years. Of these individuals, 32% had retesting performed within 3 months and 50% within 365days after treatment. Females between the ages of 20 and 29years were more likely to return for retesting than those between the ages of 30 and 39 years. Of those who returned for retesting, 10% were positive on repeat testing. In this study, 50% of females diagnosed with trichomoniasis completed retesting within 365days. Improved scheduling of clients at the time of trichomoniasis treatment and improved identification in our electronic health record of individuals diagnosed with trichomoniasis within the prior year would likely improve retesting rates. Given the high prevalence of trichomoniasis, expanded screening of asymptomatic females in settings where this is feasible may be warranted.

Local Public Health Departments at the Intersection of Climate Change, Health Equity, and Public Health Laws and Policies.

Public health laws and policies are uniquely able to mitigate the adverse and inequitable health impacts of climate change. This article summarizes some key considerations in developing such laws and policies and a variety of approaches local public health departments are using to increase climate resilience and health equity.

Ethical and Legal Issues in COVID-19 Case Investigation and Contact Tracing: A Case Study of A Large Academic Public Health Partnership.

In an effort to respond to the large surge in COVID-19 cases in Arizona that began between May and July 2020, the Arizona State University (ASU) Student Outbreak Response Team (SORT) formed a remote, volunteer-based case investigation team that worked in partnership with a local public health department through delegated public health authority.

A PUBLIC HEALTH APPROACH TO BRAIN HEALTH: THE HBI ROAD MAP SERIES

Abstract In 2005, congressional support led to the creation of the Healthy Brain Initiative (HBI) and the longstanding collaboration between the Alzheimer’s Association and the Centers for Disease Control and Prevention to advance understanding of and support for cognitive decline as a central part of public health practice. Since then, HBI partners have worked together to implement public health strategies that promote brain health, address dementia and help support caregivers. The Healthy Brain Initiative Road Map Series guides this effort. The first HBI Road Map was released by CDC and the Alzheimer’s Association in 2007 and was the first framework for viewing cognitive health and dementia as a public health issue. The second HBI Road Map was released in 2013 and expanded the role of state and local public health departments and partners in improving cognitive health. The third HBI Road Map, published in 2018, continued to chart a course for state and local public health departments and their partners by aligning actions with the essential services of public health. The HBI Road Map for Indian Country, published in 2019, is the first public health guide focused on dementia in American Indian and Alaska Native communities. The release of the fourth HBI Road Map in 2023 continues to advance the field and prepare public health departments to better address health equity and build capacity as new treatments become available. This symposium highlights successes of the Road Map Series and the development of the 4th edition of the HBI Road Map.
