Meeting Gaps in the Public Health Workforce During Emergencies: How a Nongovernmental Organization Supported Critical Staffing Needs in the COVID-19 Response.

The public health workforce continues to experience staff shortages, which hampered the ability of US state, tribal, local, and territorial health departments to respond to the COVID-19 pandemic. In April 2020, the US Centers for Disease Control and Prevention (CDC) awarded $45 million to the CDC Foundation to provide field assignees to support these health departments. To expand these efforts, the CDC provided an additional $20 million in May 2021 for vaccination efforts and $200 million in June 2021 to support COVID-19 response and general infrastructure support. The CDC Foundation worked with jurisdictions across the United States to develop job descriptions based on need and recruit nationally for positions. This expanded project, called the Workforce/Vaccine Initiative, hired 3,014 staff in 91 jurisdictions, with 2,310 (77%) hired by January 2022. Most assignments were fully remote (55%) or hybrid (28%). The largest number of staff (n=720) supported COVID-19 response work in schools. Other common functions included contact tracing/case investigation (n=456), program coordination (n=330), epidemiology (n=297), data and surveillance (n=283), and administrative support (n=220). To advance health equity and improve response efforts, 79 health equity staff were assigned to 30 jurisdictions. To support the needs of tribes, 76 field staff supported 22 tribal entities. This project demonstrated the important role of a flexible, centralized approach to rapid placement of staff in public health departments during an emergency response. While the goal of the Workforce/Vaccine Initiative was to meet short-term staffing needs, lessons learned could provide insights for building a sustainable and scalable public health workforce.

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.

The National Wastewater Surveillance System (NWSS): From inception to widespread coverage, 2020–2022, United States

Wastewater surveillance is a valuable tool that can be used to track infectious diseases in a community. In September 2020, the Centers for Disease Control and Prevention (CDC) established the National Wastewater Surveillance System (NWSS) to coordinate and build the nation's capacity to detect and quantify concentrations of SARS-CoV-2 RNA in U.S. wastewater. This is the first surveillance summary of NWSS, covering September 1, 2020 to December 31, 2022. Through partnerships with state, tribal, local, and territorial health departments, NWSS became a national surveillance platform that can be readily expanded and adapted to meet changing public health needs. Beginning with 209 sampling sites in September 2020, NWSS rapidly expanded to >1500 sites by December 2022, covering ≈47 % of the U.S. population. As of December 2022, >152,000 unique wastewater samples have been collected by NWSS partners, primarily from wastewater treatment plants (WWTPs). WWTPs participating in NWSS tend to be larger than the average U.S. WWTP and serve more populated communities. In December 2022, ≈8 % of the nearly 16,000 U.S. WWTPs were participating in NWSS. NWSS partners used a variety of methods for sampling and testing wastewater samples; however, progress is being made to standardize these methods. In July 2021, NWSS partners started submitting SARS-CoV-2 genome sequencing data to NWSS. In October 2022, NWSS expanded to monkeypox virus testing, with plans to include additional infectious disease targets in the future. Through the rapid implementation and expansion of NWSS, important lessons have been learned. Wastewater surveillance programs should consider both surge and long-term capacities when developing an implementation plan, and early standardization of sampling and testing methods is important to facilitate data comparisons across sites. NWSS has proven to be a flexible and sustainable surveillance system that will continue to be a useful complement to case-based surveillance for guiding public health action.

Understanding Health Equity in Public Health Practice in the United States.

Understanding the extent to which equity-focused work is occurring in public health departments (eg, in chronic disease programs) can identify areas of success and what is needed to move the needle on health equity. The study objective was to characterize the patterns and correlates of equity-related practices in US state and territorial public health practice. The design was a multimethod (quantitative and qualitative), cross-sectional study. The setting included US state and territorial public health departments. Chronic disease prevention practitioners (N = 600) completed self-report surveys in July 2022 through August 2022 (analyzed in September 2022 through December 2022). Health equity data were obtained across 4 domains: (1) staff skills, (2) work unit practices, (3) organizational priorities and values, and (4) partnerships and networks. There was a wide range in self-reported performance across the health equity variables. The highest values (those agreeing and strongly agreeing) were related to staff skills (eg, the ability to describe the causes of inequities [82%]). Low agreement was reported for multiple items, indicating the lack of systems for tracking progress on health equity (32%), the lack of hiring of staff members who represent disadvantaged communities (33%), and limited use of principles for community engagement (eg, sharing decision-making authority with partners [34%]). Qualitative data provided tangible examples showing how practitioners and their agencies are turning an array of health equity concepts into actions. There is urgency in addressing health equity and our data suggest considerable room for enhancing health equity practices in state and territorial public health. To support these activities, our findings provide some of the first information on areas of progress, gaps in practice, and where to target technical assistance, capacity building efforts, and accreditation planning.

Description of antibiotic stewardship expertise and activities among US public health departments, 2022

Background: In 2021, the CDC awarded >$100 million to 62 state, local, and territorial health departments (SLTHDs) to expand antibiotic stewardship expertise and implement antibiotic stewardship activities in different healthcare settings. Our objective was to describe SLTHD antibiotic stewardship personnel and activities to characterize the impact of the funding. Methods: SLTHDs submitted performance measures, including quantitative and qualitative responses, describing personnel supporting antibiotic stewardship activities, types of activities, and healthcare facilities and professionals engaged from January through June 2022. A quantitative analysis of performance measures and qualitative thematic analysis of select narrative responses are reported. Results: Most SLTHDs (58 of 62, 94%) submitted performance measures. Among them, 37 (64%) reported identifying an antibiotic stewardship leader or coleader; most were pharmacists (57%) or physicians (38%) with infectious diseases training (68%) (Table 1). Of the remaining STLHDs, 20 reported barriers to identifying a leader or coleader, including hiring process delays and programmatic barriers (Table 2). SLTHDs reported 254 antibiotic stewardship activities; most reported activities involving multiple activity types (44%). Education and communication (eg, providing stewardship expertise) was the most common single activity (30%), followed by antibiotic use tracking and reporting (13%), assessment of antibiotic stewardship implementation (8%), and action and implementation (eg, audit and feedback letters) (4%). The highest number of activities were implemented in multiple healthcare settings (35%), followed by acute care (21%), outpatient (18%), long-term care (17%), and other (9%) (Fig. 1). SLTHDs reported engaging 4,970 healthcare facilities and 15,194 healthcare professionals in antibiotic stewardship activities across healthcare settings, to date, as part of this funding opportunity (Fig. 2). Conclusions: Antibiotic stewardship funding to SLTHDs allowed for increases in capacity and expanded outreach to implement a variety of antibiotic stewardship activities across multiple healthcare settings. Sustaining STLHD antibiotic stewardship activities can help increase engagement and coordination with healthcare facilities, healthcare professionals, and other partners to optimize antibiotic prescribing and patient safety.Disclosure: None

Colonization screening positivity rates for novel multidrug-resistant organism healthcare containment responses during 2019–2022

Background: The CDC recommends a public health response when novel and targeted multidrug-resistant organisms (nMDROs), such as carbapenem-resistant organisms or Candida auris, are identified in healthcare settings in nonendemic areas. nMDRO responses are supported by healthcare-associated infection-antimicrobial resistance programs in 50 state and 6 local and territorial health departments. Annually, health departments report nMDRO responses to the CDC. We summarize nMDRO responses nationally and report our assessment of colonization screening positivity rates by healthcare setting and pathogen. Methods: We analyzed nMDRO response data reported by health departments for the period August 2019–July 2021; we excluded prevention efforts (ie, widespread screening based on facility-level risk factors). Among nMDRO responses in which colonization screening was performed, we calculated the proportion of responses in which screening detected additional cases of the index nMDRO and the colonization screening positivity, by healthcare setting and pathogen. Results: Among 2,051 nMDRO responses, 732 (36%) had ≥1 colonization screening (representing 44,845 colonization screenings), of which 24 (representing 17,467 colonization screenings) were prevention efforts and were excluded. Among the remaining 708 nMDRO responses, the healthcare setting most frequently included was acute-care hospitals (ACHs; 337 of 708, 48%); the least frequently included was long-term ACHs (LTACHs; 83 of 708, 12%). Carbapenem-resistant Enterobacterales were the most common index nMDRO prompting a response (408 of 708, 58%). Screening identified additional cases of the index nMDRO in 248 responses (35%) and 2,378 (9%) of 27,378 colonization screenings. Identification of the index nMDRO varied by pathogen and setting (Fig. 1). Overall, ventilator-capable skilled nursing facilities (vSNFs) were the facility type in which colonization screening most frequently identified additional cases of the index nMDRO (63 of 92 responses, 63%), and LTACHs had the highest colonization screening positivity (750 of 5,798, 13%). Similar colonization screening positivity was observed in ACHs (9%) and vSNFs (8%). On average, Candida auris and carbapenem-resistant Acinetobacter baumannii (CRAB) had the highest colonization screening positivity rates across all healthcare settings: CRAB, 493 (12.6%) of 3,907 screened; Candida auris, 1,344 (11.7%) of 11,466 screened (Fig. 1B). More than one-half of responses identified ≥1 case of the index nMDRO. Conclusions: During public health nMDRO responses, additional cases were regularly identified through colonization screening. Responses in vSNFs and LTACHs and to environmental pathogens like Candida auris and CRAB detected additional cases in more than one-half of responses, suggesting that spread commonly occurred prior to detection of the first clinical case. The use of colonization screening is an effective strategy to detect unidentified nMDRO colonization, especially in high-acuity postacute-care settings.Disclosures: None

Epidemiologic Trends of Dengue in U.S. Territories, 2010-2020.

Dengue is one of the most common vectorborne flaviviral infections globally, with frequent outbreaks in tropical regions. In 2019 and 2020, the Pan American Health Organization reported approximately 5.5 million dengue cases from the Americas, the highest number on record. In the United States, local dengue virus (DENV) transmission has been reported from all U.S. territories, which are characterized by tropical climates that are highly suitable for Aedes species of mosquitoes, the vector that transmits dengue. Dengue is endemic in the U.S. territories of American Samoa, Puerto Rico, and the U.S. Virgin Islands (USVI). Dengue risk in Guam and the Commonwealth of the Northern Mariana Islands is considered sporadic or uncertain. Despite all U.S. territories reporting local dengue transmission, epidemiologic trends over time have not been well described. 2010-2020. State and territorial health departments report dengue cases to CDC through ArboNET, the national arboviral surveillance system, which was developed in 2000 to monitor West Nile virus infections. Dengue became nationally notifiable in ArboNET in 2010. Dengue cases reported to ArboNET are categorized using the 2015 Council of State and Territorial Epidemiologists case definition. In addition, DENV serotyping is performed at CDC's Dengue Branch Laboratory in a subset of specimens to support identification of circulating DENV serotypes. During 2010-2020, a total of 30,903 dengue cases were reported from four U.S. territories to ArboNET. Puerto Rico reported the highest number of dengue cases (29,862 [96.6%]), followed by American Samoa (660 [2.1%]), USVI (353 [1.1%]), and Guam (28 [0.1%]). However, annual incidence rates were highest in American Samoa with 10.2 cases per 1,000 population in 2017, followed by Puerto Rico with 2.9 in 2010 and USVI with 1.6 in 2013. Approximately one half (50.6%) of cases occurred among persons aged <20 years. The proportion of persons with dengue who were hospitalized was high in three of the four territories: 45.5% in American Samoa, 32.6% in Puerto Rico, and 32.1% in Guam. In Puerto Rico and USVI, approximately 2% of reported cases were categorized as severe dengue. Of all dengue-associated deaths, 68 (0.2%) were reported from Puerto Rico; no deaths were reported from the other territories. During 2010-2020, DENV-1 and DENV-4 were the predominant serotypes in Puerto Rico and USVI. U.S. territories experienced a high prevalence of dengue during 2010-2020, with approximately 30,000 cases reported, and a high incidence during outbreak years. Children and adolescents aged <20 years were disproportionately affected, highlighting the need for interventions tailored for this population. Ongoing education about dengue clinical management for health care providers in U.S. territories is important because of the high hospitalization rates reported. Dengue case surveillance and serotyping can be used to guide future control and prevention measures in these areas. The Advisory Committee on Immunization Practices recommends vaccination with Dengvaxia for children aged 9-16 years with evidence of previous dengue infection and living in areas where dengue is endemic. The recommendation for the dengue vaccine offers public health professionals and health care providers a new intervention for preventing illness and hospitalization in the age group with the highest burden of disease in the four territories (Paz Bailey G, Adams L, Wong JM, et al. Dengue Vaccine: Recommendations of the Advisory Committee on Immunization Practices, United States, 2021. MMWR Recomm Rep 2021;70[No. RR-6]). American Samoa, Puerto Rico, and USVI are all considered endemic areas and persons residing in these areas are eligible for the new dengue vaccine. Persons aged 9-16 years in those jurisdictions with laboratory evidence of previous dengue infection can receive the dengue vaccine and benefit from a reduced risk for symptomatic disease, hospitalization, or severe dengue. Health care providers in these areas should be familiar with the eligibility criteria and recommendations for vaccination to reduce the burden of dengue among the group at highest risk for symptomatic illness. Educating health care providers about identification and management of dengue cases can improve patient outcomes and improve surveillance and reporting of dengue cases.

“This is a T.E.S.T.” (Tabletop Exercise Simulation Tool): Using Gamification to Train Public Health Staff in Community Reception Centers for a Nuclear or Radiological Incident

Introduction:After a nuclear or radiological (nuc/rad) incident, there is a need to screen, potentially decontaminate, and monitor the affected population. A Community Reception Center (CRC) is a site that provides these services, plus more, to those displaced by a large-scale incident. By using CRCs, federal agencies and state, tribal, local, and territorial (STLT) health departments can monitor the affected population, help prevent hospitals from becoming overburdened with persons not critically injured, compliment shelter operations, and obtain a basis for a long-term registry. However, public health staff often are not fully trained in their CRC role and the decision-making factors.Method:The Centers for Disease Control and Prevention (CDC) developed a unique training board game, “This is a T.E.S.T.” (Tabletop Exercise Simulation Tool), for public health staff about their CRC role and decision-making factors. We play-tested the game with several CDC and STLT staff in 2022 and received informal feedback.Results:Players found the game facilitated discussion and identified gaps in CRC plans, safety hazards, population needs, and staffing requirements. They also said the game improved collaboration and communication. Over 90% of players strongly agreed the game accurately simulated both bottlenecks and resource needs, individual needs and anxiety, and allowed a greater understanding of CRC operations.Conclusion:Games have been used for emergency response using different platforms such as virtual reality and video games. This is a T.E.S.T. facilitates collaboration by tasking players with managing resources, staff fatigue, public anxiety, and hazards. Players provided valuable feedback on its usability while learning more about CRCs. “This is a T.E.S.T” provides a unique, innovative training experience that incorporates components from typical tabletop and full-scale exercises, CRC capacity estimates through CDC’s CRC SimPLER (Simulation Program for Leveraging and Evaluating Resources), and key principles of adult learning.

Defining County-Level Terrestrial Rabies Freedom Using the US National Rabies Surveillance System: Surveillance Data Analysis

Rabies is a deadly zoonotic disease with nearly 100% fatality rate. In the United States, rabies virus persists in wildlife reservoirs, with occasional spillover into humans and domestic animals. The distribution of reservoir hosts in US counties plays an important role in public health decision-making, including the recommendation of lifesaving postexposure prophylaxis upon suspected rabies exposures. Furthermore, in surveillance data, it is difficult to discern whether counties have no cases reported because rabies was not present or because counties have an unreported rabies presence. These epizootics are monitored by the National Rabies Surveillance System (NRSS), to which approximately 130 state public health, agriculture, and academic laboratories report animal rabies testing statistics. Historically, the NRSS classifies US counties as free from terrestrial rabies if, over the previous 5 years, they and any adjacent counties did not report any rabies cases and they tested ≥15 reservoir animals or 30 domestic animals. This study aimed to describe and evaluate the historical NRSS rabies-free county definition, review possibilities for improving this definition, and develop a model to achieve more precise estimates of the probability of terrestrial rabies freedom and the number of reported county-level terrestrial rabies cases. Data submitted to the NRSS by state and territorial public health departments and the US Department of Agriculture Wildlife Services were analyzed to evaluate the historical rabies-free definition. A zero-inflated negative binomial model created county-level predictions of the probability of rabies freedom and the expected number of rabies cases reported. Data analyzed were from all animals submitted for laboratory diagnosis of rabies in the United States from 1995 to 2020 in skunk and raccoon reservoir territories, excluding bats and bat variants. We analyzed data from 14,642 and 30,120 county-years in the raccoon and skunk reservoir territories, respectively. Only 0.85% (9/1065) raccoon county-years and 0.79% (27/3411) skunk county-years that met the historical rabies-free criteria reported a case in the following year (99.2% negative predictive value for each), of which 2 were attributed to unreported bat variants. County-level model predictions displayed excellent discrimination for detecting zero cases and good estimates of reported cases in the following year. Counties classified as rabies free rarely (36/4476, 0.8%) detected cases in the following year. This study concludes that the historical rabies freedom definition is a reasonable approach for identifying counties that are truly free from terrestrial raccoon and skunk rabies virus transmission. Gradations of risk can be measured using the rabies prediction model presented in this study. However, even counties with a high probability of rabies freedom should maintain rabies testing capacity, as there are numerous examples of translocations of rabies-infected animals that can cause major changes in the epidemiology of rabies.

COVID-19 messages targeting young people on social media: content analysis of Australian health authority posts.

Health authorities utilized social media during the COVID-19 pandemic to disseminate critical and timely health messages, specifically targeting priority groups such as young people. To understand how social media was used for this purpose, we investigated the content of COVID-19-related social media posts targeting young people (16-29 years old) shared by Australian health departments. Posts targeting young people with COVID-19 information were extracted from all eight Australian State and Territory health department Facebook, Instagram and TikTok accounts over 1 month of the Delta outbreak (September 2021) and analysed thematically. In total, 238 posts targeting young people were identified from 1059 COVID-19 posts extracted. All eight health departments used Facebook, five used Instagram and only one used TikTok. The majority of posts implicitly targeted young people; only 14.7% explicitly mentioned age or 'young people'. All posts included accompanying visuals; 77% were still images like photos or illustrations whilst 23% were moving images like videos and GIFs. Communication techniques included calls to action (63% of posts), responsive communication (32% of posts) and positive emotional appeal (31% of posts). Social marketing techniques catering to young people were used to varying extents despite receiving higher levels of engagement; 45% featured emojis whilst only 16% used humour, 14% featured celebrities and 6% were memes. Priority groups like ethnic/cultural groups and chronic health/disability communities were rarely targeted in this communication. The findings indicate a lack of health communication on social media directed towards young people, highlighting an opportunity for increased use of platforms like TikTok and trends popular with young people online.

Rabies surveillance in the United States during 2021.

To provide epidemiological information on the occurrence of animal and human rabies in the US during 2021 and summaries of 2021 rabies surveillance for Canada and Mexico. State and territorial public health departments and USDA Wildlife Services provided data on animals submitted for rabies testing in 2021. Data were analyzed temporally and geographically to assess trends in domestic animal and wildlife rabies cases. During 2021, 54 US jurisdictions reported 3,663 rabid animals, representing an 18.2% decrease from the 4,479 cases reported in 2020. Texas (n = 456 [12.4%]), Virginia (297 [8.1%]), Pennsylvania (287 [7.8%]), North Carolina (248 [6.8%]), New York (237 [6.5%]), California (220 [6.0%]), and New Jersey (201 [5.5%]) together accounted for > 50% of all animal rabies cases reported in 2021. Of the total reported rabid animals, 3,352 (91.5%) involved wildlife, with bats (n = 1,241 [33.9%]), raccoons (1,030 [28.1%]), skunks (691 [18.9%]), and foxes (314 [8.6%]) representing the primary hosts confirmed with rabies. Rabid cats (216 [5.9%]), cattle (40 [1.1%]), and dogs (36 [1.0%]) accounted for 94% of rabies cases involving domestic animals in 2021. Five human rabies deaths were reported in 2021. The number of animal rabies cases reported in the US decreased significantly during 2021; this is thought to be due to factors related to the COVID-19 pandemic.

Hospital policies on falls in relation to patients with communication disability: a scoping review and content analysis.

ObjectiveFalls in hospital are a significant public health issue and patients with communication disability have unique risk factors that have the potential to contribute to falls. The aim of this study is to determine how the content of hospital falls policies relate to patients with communication disability and to identify gaps in policy that need to be addressed.MethodsA scoping review and content analysis of (a) policies and related documents, from a target health service in Victoria, Australia, and all relevant Australian state and territory health departments, and (b) national guidelines was performed. Data were analysed for content relating to inclusion of patients with communication disability.ResultsCommunication disability is not captured as a risk factor for a fall in assessment tools. When included, aspects of communication disability were often conflated with cognitive impairments. There was little guidance for staff on adapting falls prevention education to suit the needs of patients with communication disability and limited identified role for speech pathologists.ConclusionThis study suggests that a patient's communication disability is not visible in hospital falls policies and guidelines.

Population-Based Linked Longitudinal Surveillance of Pregnant People and Their Infants: A Critical Resource for Emerging, Re-Emerging, and Persistent Threats.

Public health emergencies, from Zika to COVID-19, have underscored the importance of addressing the needs of pregnant people and their infants. Recent events have underlined the critical role of mother-infant-linked longitudinal surveillance to characterize and assess the impacts of emerging, re-emerging, and persistent threats, including infectious diseases, on these populations. In partnership with state, local, and territorial health departments, CDC's National Center on Birth Defects and Developmental Disabilities activated the Surveillance for Emerging Threats to Mothers and Babies Network (SET-NET) to capture information about pregnant people with laboratory-confirmed infection with SARS-CoV-2 (the virus that causes COVID-19) and their infants. SET-NET data were critical in recognizing the severe risks of COVID-19 during pregnancy, which ultimately informed clinical decisions and public health policy, specifically vaccine prioritization at the local, state, and national levels. This commentary describes the activation of SET-NET to monitor COVID-19 in pregnancy and highlights the experiences of health departments. We provide examples of how SET-NET findings informed COVID-19 prevention efforts and public health policy. Lastly, we identify opportunities to improve and advance surveillance efforts to protect the health of pregnant people and their infants in the United States from current and future threats.

Enhancing the Applied Epidemiology Workforce: The Impact of the 2021 Epidemiology Capacity Assessment on CSTE's Workforce Priorities.

The Council of State and Territorial Epidemiologists (CSTE) conducted the seventh Epidemiology Capacity Assessment (ECA) from January to April 2021 in state and territorial health departments. The ECA serves to enumerate the applied epidemiology workforce and evaluate workforce capacity across the nation. The results of the ECA demonstrated a need for additional epidemiologists across jurisdictions and challenges of maintaining a trained workforce and improving public health infrastructure. The results of the ECA serve as the foundation for CSTE's workforce priorities, which focus on transforming applied epidemiology by promoting the field as a career opportunity, recruitment, and retention strategies, upskilling the workforce, and enhancing infrastructure. CSTE has outlined current and future workforce priorities, and these priorities contribute to a larger strategy to transform the field and enhance applied epidemiology capacity nationwide. This report describes the programmatic actions taken by CSTE in response to the results of the 2021 ECA.

Monitoring the incidence and causes of disease potentially transmitted by food in Australia: Annual report of the OzFoodNet network, 2017.

In 2017, 47,652 notifications of enteric diseases potentially related to food were received by state and territory health departments in Australia. Consistent with previous years, the majority of all notified infections were either campylobacteriosis (n = 28,432; 60%) or salmonellosis (n = 16,416; 34%). A total of 206 gastrointestinal outbreaks, including 179 foodborne outbreaks, were reported in 2017. The remaining 27 outbreaks were due to environmental or probable environmental transmission (22 outbreaks), animal-to person or probable animal-to-person transmission (three outbreaks), and waterborne or probable waterborne transmission (two outbreaks). Foodborne outbreaks affected 2,130 people resulting in at least 290 hospital admissions and five deaths. Eggs continue to be a source of Salmonella Typhimurium infection across the country, with 49 egg-related outbreaks affecting at least 746 people reported across six jurisdictions in 2017.

Incidence of COVID-19 Among Persons Experiencing Homelessness in the US From January 2020 to November 2021

A lack of timely and high-quality data is an ongoing challenge for public health responses to COVID-19 among people experiencing homelessness (PEH). Little is known about the total number of cases of COVID-19 among PEH. To estimate the number of COVID-19 cases among PEH and compare the incidence rate among PEH with that in the general population. This cross-sectional study used data from a survey distributed by the Centers for Disease Control and Prevention to all US state, district, and territorial health departments that requested aggregated COVID-19 data among PEH from January 1, 2020, to September 30, 2021. Jurisdictions were encouraged to share the survey with local health departments. The primary study outcome was the number of cases of COVID-19 identified among PEH. COVID-19 cases and incidence rates among PEH were compared with those in the general population in the same geographic areas. Participants included a population-based sample of all 64 US jurisdictional health departments. Overall, 25 states, districts, and territories completed the survey, among which 18 states (72.0%) and 27 localities reported COVID-19 data among PEH. A total of 26 349 cases of COVID-19 among PEH were reported at the state level and 20 487 at the local level. The annual incidence rate of COVID-19 among PEH at the state level was 567.9 per 10 000 person-years (95% CI, 560.5-575.4 per 10 000 person-years) compared with 715.0 per 10 000 person-years (95% CI, 714.5-715.5 per 10 000 person-years) in the general population. At the local level, the incidence rate of COVID-19 among PEH was 799.2 per 10 000 person-years (95% CI, 765.5-834.0 per 10 000 person-years) vs 812.5 per 10 000 person-years (95% CI, 810.7-814.3 per 10 000 person-years) in the general population. These results provide an estimate of COVID-19 incidence rates among PEH in multiple US jurisdictions; however, a national estimate and the extent of under- or overestimation remain unknown. The findings suggest that opportunities exist for incorporating housing and homelessness status in infectious disease reporting to inform public health decision-making.
