Professionalization of the public health workforce: scoping review and call to action.

BACKGROUND: The 'WHO-ASPHER Roadmap to Professionalizing the Public Health Workforce in the European Region' provides recommendations for strategic and systematic workforce planning around professionalization levers including: (i) competencies, (ii) training and education, (iii) formal organization, (iv) professional credentialing and (v) code of ethics and professional conduct as well as taxonomy and enumeration. It was based on a literature review till 2016. This scoping review aims to explore how the professionalization was documented in the literature between 2016 and 2022. METHODS: Following the Joanna Briggs Institute guidelines, we searched Medline via PubMed, Web of Science, ERIC via EBSCO and Google Scholar and included studies on professionalization levers. Four critical appraisal tools were used to assess qualitative, quantitative, mixed methods studies and grey literature. The PRISMA Extension for Scoping Reviews (PRISMA-ScR) was used for reporting. RESULTS: Eleven articles included in this review spanned 61 countries, targeting undergraduate, master's, doctoral degrees and continuing professional development. Most of these documents were reviews. About half provided a definition of the public health workforce; more than half covered the taxonomy and included information about competences, but the use of frameworks was sporadic and inconsistent. Formal organization and the necessity of a code of conduct for the public health workforce were acknowledged in only two studies. CONCLUSIONS: In spite of some efforts to professionalize the public health workforce, this process is fragmented and not fully recognized and supported. There is an urgent need to engage policymakers and stakeholders to prioritize investments in strengthening the public health workforce worldwide.

Trends in Degree Conferrals, Degree-Associated Debt, and Employment Outcomes Among Undergraduate Public Health Degree Graduates, 2001‒2020.

Objectives. To characterize the trends in degree conferrals, degree-associated debt, and employment outcomes among undergraduate public health degree (UGPHD) graduates. Methods. We reported administrative data on degree conferrals from 2001 to 2020 from the National Center for Education Statistics (NCES). For alumni graduating from 2015 to 2019, we also reported degree-associated debt and earnings 1 year after graduation compiled by NCES. Finally, we utilized a data set on 1-year postgraduation employment outcomes for graduates from 2015 to 2020 from the Association of Schools and Programs of Public Health. Results. As of 2020, more than 18 000 UGPHDs were awarded each year, more than 140 000 in total over the past 20 years. UGPHD graduates are highly diverse, with more than 80% being women and 55% being individuals from communities of color. We find alumni worked mostly in for-profit organizations (34%), health care (28%), nonprofits (11%), academic organizations (10%), government (10%), and other (6%). Degree-associated debt was $24 000, and the median first-year earnings were $34 000. Conclusions. While growth in UGPHD conferrals has slowed, it remains among the fastest-growing degree in the nation. However, the limited pathways into government remains a significant challenge.

First-Destination Outcomes for 2015-2018 Public Health Graduates: Focus on Employment.

Objectives. To improve understanding of the future public health workforce by analyzing first-destination employment outcomes of public health graduates.Methods. We assessed graduate outcomes for those graduating in 2015-2018 using descriptive statistics and the Pearson χ2 test.Results. In our analysis of data on 53 463 graduates, we found that 73% were employed; 15% enrolled in further education; 5% entered a fellowship, internship, residency, volunteer, or service program; and 6% were not employed. Employed graduates went to work in health care (27%), corporations (24%), academia (19%), government (17%), nonprofit (12%), and other sectors (1%). In 2018, 9% of bachelor's, 4% of master's, and 2% of doctoral graduates were not employed but seeking employment.Conclusions. Today's public health graduates are successful in finding employment in various sectors. This new workforce may expand public health's reach and lead to healthier communities overall.Public Health Implications. With predicted shortages in the governmental public health workforce and expanding hiring because of COVID-19, policymakers need to work to ensure the supply of public health graduates meets the demands of the workforce.

Formaldehyde-induced hematopoietic stem and progenitor cell toxicity in mouse lung and nose.

Formaldehyde (FA), an economically important and ubiquitous chemical, has been classified as a human carcinogen and myeloid leukemogen. However, the underlying mechanisms of leukemogenesis remain unclear. Unlike many classical leukemogens that damage hematopoietic stem/progenitor cells (HSC/HPC) directly in the bone marrow, FA-as the smallest, most reactive aldehyde-is thought to be incapable of reaching the bone marrow through inhalation exposure. A recent breakthrough study discovered that mouse lung contains functional HSC/HPC that can produce blood cells and travel bi-directionally between the lung and bone marrow, while another early study reported the presence of HSC/HPC in rat nose. Based on these findings, we hypothesized that FA inhalation could induce toxicity in HSC/HPC present in mouse lung and/or nose rather than in the bone marrow. To test this hypothesis, we adapted a commercially available protocol for culturing burst-forming unit-erythroid (BFU-E) and colony-forming unit-granulocyte, macrophage (CFU-GM) colonies from bone marrow and spleen to also enable culture of these colonies from mouse lung and nose, a novel application of this assay. We reported that in vivo exposure to FA at 3 mg/m3 or ex vivo exposure up to 400 µM FA decreased the formation of both colony types from mouse lung and nose as well as from bone marrow and spleen. These findings, to the best of our knowledge, are the first empirically to show that FA exposure can damage mouse pulmonary and olfactory HSC/HPC and provide potential biological plausibility for the induction of leukemia at the sites of entry rather than the bone marrow.

Employment outcomes and job satisfaction of international public health professionals: What lessons for public health and COVID-19 pandemic preparedness? Employment outcomes of public health graduates.

The profile of public health professionals (PHPs) and COVID-19 preparedness is assessed against the employment outcomes (EO), precarious employment (PE), and job satisfaction (JS) of the European Public Health Master programme alumni. The study is descriptive, cross-sectional, conducted from May-October 2020. A survey was developed to assess the EO, PE and JS. Participants were recruited by email. SPSS statistics 26 version was used to perform descriptive analysis. A total of 189 PHPs participated (65% response) with majority women (66%), the mean age was 36 years. Participants were employed (80%), in non-governmental organisations (20%), and academia (19%). Common employment positions were managerial (37%) and consultancy (18%). Majority of PHPs were exposed to PE (81%), the most frequent elements were 'temporary employment' (54%), and 'the lack of labour union' (53%). The JS of PHPs was 'satisfied'. A blend of scientific public health knowledge and interpersonal competencies, reforms in current employment conditions, development of professional entities to safeguard PHPs' rights, and continuous investment in public health is necessary for PHPs to strengthen COVID-19 pandemic preparedness. Furthermore, monitoring and evaluation of EO and JS are crucial to prepare PHPs according to the needs of the employment market and to be aware of PHPs' needs.

Genetic and Epidemiologic Trends of Norovirus Outbreaks in the United States from 2013 to 2016 Demonstrated Emergence of Novel GII.4 Recombinant Viruses.

Noroviruses are the most frequent cause of epidemic acute gastroenteritis in the United States. Between September 2013 and August 2016, 2,715 genotyped norovirus outbreaks were submitted to CaliciNet. GII.4 Sydney viruses caused 58% of the outbreaks during these years. A GII.4 Sydney virus with a novel GII.P16 polymerase emerged in November 2015, causing 60% of all GII.4 outbreaks in the 2015-2016 season. Several genotypes detected were associated with more than one polymerase type, including GI.3, GII.2, GII.3, GII.4 Sydney, GII.13, and GII.17, four of which harbored GII.P16 polymerases. GII.P16 polymerase sequences associated with GII.2 and GII.4 Sydney viruses were nearly identical, suggesting common ancestry. Other common genotypes, each causing 5 to 17% of outbreaks in a season, included GI.3, GI.5, GII.2, GII.3, GII.6, GII.13, and GII.17 Kawasaki 308. Acquisition of alternative RNA polymerases by recombination is an important mechanism for norovirus evolution and a phenomenon that was shown to occur more frequently than previously recognized in the United States. Continued molecular surveillance of noroviruses, including typing of both polymerase and capsid genes, is important for monitoring emerging strains in our continued efforts to reduce the overall burden of norovirus disease.

High-Throughput Next-Generation Sequencing of Polioviruses.

The poliovirus (PV) is currently targeted for worldwide eradication and containment. Sanger-based sequencing of the viral protein 1 (VP1) capsid region is currently the standard method for PV surveillance. However, the whole-genome sequence is sometimes needed for higher resolution global surveillance. In this study, we optimized whole-genome sequencing protocols for poliovirus isolates and FTA cards using next-generation sequencing (NGS), aiming for high sequence coverage, efficiency, and throughput. We found that DNase treatment of poliovirus RNA followed by random reverse transcription (RT), amplification, and the use of the Nextera XT DNA library preparation kit produced significantly better results than other preparations. The average viral reads per total reads, a measurement of efficiency, was as high as 84.2% ± 15.6%. PV genomes covering >99 to 100% of the reference length were obtained and validated with Sanger sequencing. A total of 52 PV genomes were generated, multiplexing as many as 64 samples in a single Illumina MiSeq run. This high-throughput, sequence-independent NGS approach facilitated the detection of a diverse range of PVs, especially for those in vaccine-derived polioviruses (VDPV), circulating VDPV, or immunodeficiency-related VDPV. In contrast to results from previous studies on other viruses, our results showed that filtration and nuclease treatment did not discernibly increase the sequencing efficiency of PV isolates. However, DNase treatment after nucleic acid extraction to remove host DNA significantly improved the sequencing results. This NGS method has been successfully implemented to generate PV genomes for molecular epidemiology of the most recent PV isolates. Additionally, the ability to obtain full PV genomes from FTA cards will aid in facilitating global poliovirus surveillance.

Expectations of employers in the United States for entry-level public health job skills with a bachelor's degree: an analysis of the positions advertised in an online job portal.

Objectives: To analyze the current public health labor market for bachelor's-level graduates. Methods: Public health-related job postings (N = 365) from across the United States were collected from an online job portal, Indeed.com, from November 7-14, 2022. Job titles, organization type, degree requirements, work experience, job location, and preferred skills for bachelor's-level public health positions were analyzed. Results: Thirty-one job titles were identified. Approximately one-third (32.33%) of postings were from the Northeastern US; 23.56% were from the Southeastern region. Thirty-five job skill categories were identified. Most jobs (92.33%) required oral and written communication skills, and 85.21% specified educational skills for public health promotion. Cultural competency, project management, and case management abilities were also highly sought. Conclusion: This study revealed the needs of the public health workforce and bolstered the case that public health degree-seekers should be equipped with a set of strategic skills applicable to a range of multisectoral and multidisciplinary public health jobs. Policy implications: Given the rapid changes in the field of public health, ongoing analysis of the labor market benefits educators, employers, and policymakers alike.

Revolutionizing the Public Health Workforce-A Policy Brief in Retrospect of the World Congress on Public Health Rome 2020.

Background: The COVID-19 pandemic dramatically illustrates the consequences of inadequate prioritization of the Public Health Workforce (PHW). This Policy Brief introduces a Call for Action following the plenary session entitled "Revolutionising the Public Health Workforce (PHW) as Agents of Change" as part of the 2020 World Congress on Public Health. Policy Options and Recommendations: In order to revolutionize the PHW, five long-term key approaches are proposed: 1. Transforming public health competencies through transdisciplinary education and inter-professional training; 2. Revolutionizing educational systems by shifting the public health paradigm; 3. Linking public health education and work opportunities; 4. Overcoming the paradoxical shortage and overproduction of graduates and 5. Developing adaptable, multisectoral agents of change. Conclusion: Public health education of the future requires a paradigm shift towards a holistic understanding of public health, characterized by transdisciplinary education, inter-professional training and a closer integration of academia, health services, and communities.

Education for public health 2030: transformation to meet health needs in a changing world.

Education for public health is at a critical inflection point, and either transforms for success or fails to remain relevant. In 2020, the Association for Schools and Programs of Public Health launched an initiative, Framing the Future 2030: Education for Public Health (FTF 2030) to develop a resilient educational system for public health that promotes scientific inquiry, connects research, education, and practice, eliminates inequities, incorporates anti-racism principles, creates and sustains diverse and inclusive teaching and learning communities, and optimizes systems and resources to prepare graduates who are clearly recognizable for their population health perspectives, knowledge, skills, attitudes, and practices. Three expert panels: (1) Inclusive excellence through an anti-racism lens; (2) Transformative approaches to teaching and learning; and (3) Expanding the reach, visibility, and impact of the field of academic public health are engaged in ongoing deliberations to generate recommendations to implement the necessary change. The article describes the panels' work completed thus far, a "Creating an Inclusive Workspace" guide, and work planned, including questions for self-evaluation, deliberation, and reflection toward actions that support academe in developing a resilient education system for public health, whether beginning or advancing through a process of change. The FTF 2030 steering committee asserts its strong commitment to structural and substantial change that strengthens academic public health as an essential component of a complex socio-political system. Lastly, all are called to join the effort as collaboration is essential to co-develop an educational system for public health that ensures health equity for all people, everywhere.

What matters for health? Public views from eight countries.

INTRODUCTION: Despite growing scholarship on the social determinants of health (SDoH), wider action remains in its early stages. Broad public understanding of SDoH can help catalyse such action. This paper aimed to document public perception of what matters for health from countries with broad geographic, cultural, linguistic, population composition, language and income level variation. METHODS: We conducted an online survey in Brazil, China, Germany, Egypt, India, Indonesia, Nigeria and the USA to assess rankings of what respondents thought matters for health and what they perceived decision makers think matters for health. We analysed the percentages of each determinant rated as the most important for good health using two metrics: the top selection and a composite of the top three selections. We used two-tailed χ2 test for significance testing between groups. RESULTS: Of 8753 respondents, 56.2% (95% CI 55.1% to 57.2%) ranked healthcare as the most important determinant of good health using the composite metric. This ranking was consistent across countries except in China where it appeared second. While genetics was cited as the most important determinant by 22.3% (95% CI 21.5% to 23.2%) of the overall sample with comparable rates in most countries, the percentage increased to 33.3% (95% CI 30.5% to 36.3%) in Germany and 35.9% (95% CI 33.0% to 38.8%) in the USA. Politics was the determinant with the greatest absolute difference (18.5%, 95% CI 17.3% to 19.6%) between what respondents considered matters for health versus what they perceived decision makers think matters for health. CONCLUSION: The majority of people consider healthcare the most important determinant of health, well above other social determinants. This highlights the need for more investment in communication efforts around the importance of SDoH.

Next-generation sequencing of human respiratory syncytial virus subgroups A and B genomes.

Human respiratory syncytial virus (HRSV) is a leading cause of acute respiratory illness in young children worldwide. Whole genome sequencing of HRSV offers enhanced resolution of strain variability for epidemiological surveillance and provides genomic information essential for antiviral and vaccine development. A 10-amplicon one-step RT-PCR assay and a 20-amplicon nested RT-PCR assay with enhanced sensitivity were developed to amplify whole HRSV genomes from samples containing high and low viral loads, respectively. Ninety-six HRSV-positive samples comprised of 58 clinical specimens and 38 virus isolates with Ct values ≤ 24 were amplified successfully using the 10-amplicon one-step RT-PCR method and multiplexed in a single MiSeq run. Genome coverage exceeded 99.3% for all 96 samples. The 20-amplicon nested RT-PCR NGS method was used to generate >99.6% HRSV full-length genome for 72 clinical specimens with Ct values ranging from 24 to 33. Phylogenetic analysis of the genome sequences obtained from the 130 clinical specimens revealed a wide diversity of HRSV genotypes demonstrating methodologic robustness.

Metagenomic sequencing generates the whole genomes of porcine rotavirus A, C, and H from the United States.

The genus Rotavirus comprises eight species, designated A to H, and two recently identified tentative species I in dogs and J in bats. Species Rotavirus A, B, C and H (RVA, RVB, RVC and RVH) have been detected in humans and animals. While human and animal RVA are well characterized and defined, complete porcine genome sequences in the GenBank are limited compared to human strains. Here, we used a metagenomic approach to sequence the 11 segments of RVA, RVC and RVH strains from piglets in the United States (US) and explore the evolutionary relations of these RV species. Metagenomics identified Astroviridae, Picornaviridae, Caliciviridae, Coronoviridae in samples MN9.65 and OK5.68 while Picobirnaviridae and Arteriviridae were only identified in sample OK5.68. Whole genome sequencing and phylogenetic analyses identified multiple genotypes with the RVA of strain MN9.65 and OK5.68, with the genome constellation of G5/G9-P[7]/P[13]-I5/I5- R1/R1-C1-M1-A8-N1-T7-E1/E1-H1 and G5/G9-P[6]/P[7]-I5-R1/R1-C1-M1-A8-N1-T1/T7-E1/E1-H1, respectively. The RVA strains had a complex evolutionary relationship with other mammalian strains. The RVC strain OK5.68 had a genome constellation of G9-P[6]-I1-R1-C5-M6-A5-N1-T1-E1-H1, and shared an evolutionary relationship with porcine strains from the US. The RVH strains MN9.65 and OK5.68 had the genome constellation of G5-P1-I1-R1-C1-M1-A5-N1-T1-E4-H1 and G5-P1-I1-R1-C1-M1-A5-N1-T1-E1-H1, indicating multiple RVH genome constellations are circulating in the US. These findings allow us to understand the complexity of the enteric virome, develop improved screening methods for RVC and RVH strains, facilitate expanded rotavirus surveillance in pigs, and increase our understanding of the origin and evolution of rotavirus species.

A Statement of Commitment to Zero Tolerance of Harassment and Discrimination in Schools and Programs of Public Health.

The Association of Schools and Programs of Public Health convened a Task Force on Zero Tolerance of Harassment and Discrimination in 2019 to develop a policy statement and strategies for addressing harassment of all types in institutions offering public health education. We outline the premises and scholarly foundation for the development of the Statement of Commitment to Zero Tolerance of Harassment and Discrimination, the statement itself, and future plans for realizing the aspiration established in the statement. The development of this living document is predicated on the belief that it is the core responsibility of academic institutions to build the knowledge and that it is the responsibility of leaders, namely deans of schools of public health and directors of public health programs, to lead in building the shared knowledge and insist on the practices that create institutions for a better future free of harassment and discrimination. Our statement is informed by the knowledge that aggressions in the form of harassment and discrimination undermine the health and well-being of individuals, the public, and populations.

Comparison of Illumina MiSeq and the Ion Torrent PGM and S5 platforms for whole-genome sequencing of picornaviruses and caliciviruses.

Next-generation sequencing is a powerful tool for virological surveillance. While Illumina® and Ion Torrent® sequencing platforms are used extensively for generating viral RNA genome sequences, there is limited data comparing different platforms. The Illumina MiSeq, Ion Torrent PGM and Ion Torrent S5 platforms were evaluated using a panel of sixteen specimens containing picornaviruses and human caliciviruses (noroviruses and sapoviruses). The specimens were processed, using combinations of three library preparation and five sequencing kits, to assess the quality and completeness of assembled viral genomes, and an estimation of cost per sample to generate the data was calculated. The choice of library preparation kit and sequencing platform was found to impact the breadth of genome coverage and accuracy of consensus viral genomes. The Ion Torrent S5 510 chip runs produced more reads at a lower cost per sample than the highest output Ion Torrent PGM 318 chip run, and generated the highest proportion of reads for enterovirus D68 samples. However, indels at homopolymer regions impacted the accuracy of consensus genome sequences. For lower throughput sequencing runs (i.e., Ion Torrent 510 and Illumina MiSeq Nano V2), the cost per sample was lower on the MiSeq platform, whereas with higher throughput runs (Ion Torrent 530 and Illumina MiSeq V2) there is less of a difference in the cost per sample between the two sequencing platforms ($5.47-$10.25 more per sample for an Ion Torrent 530 chip run when multiplexing 24 samples). These findings suggest that the Ion Torrent S5 and Illumina MiSeq platforms are both viable options for genomic sequencing of RNA viruses, each with specific advantages and tradeoffs.

Genetic diversity of human sapovirus across the Americas.

BACKGROUND: Sapoviruses are responsible for sporadic and epidemic acute gastroenteritis worldwide. Sapovirus typing protocols have a success rate as low as 43% and relatively few complete sapovirus genome sequences are available to improve current typing protocols. OBJECTIVE/STUDY DESIGN: To increase the number of complete sapovirus genomes to better understand the molecular epidemiology of human sapovirus and to improve the success rate of current sapovirus typing methods, we used deep metagenomics shotgun sequencing to obtain the complete genomes of 68 sapovirus samples from four different countries across the Americas (Guatemala, Nicaragua, Peru and the US). RESULTS: VP1 genotyping showed that all sapovirus sequences could be grouped in the four established genogroups (GI (n = 13), GII (n = 30), GIV (n = 23), GV (n = 2)) that infect humans. They include the near-complete genome of a GI.6 virus and a recently reported novel GII.8 virus. Sequences of the complete RNA-dependent RNA polymerase gene could be grouped into three major genetic clusters or polymerase (P) types (GI.P, GII.P and GV.P) with all GIV viruses harboring a GII polymerase. One (GII.P-GII.4) of the new 68 sequences was a recombinant virus with the hotspot between the NS7 and VP1 regions. CONCLUSIONS: Analyses of this expanded database of near-complete sapovirus sequences showed several mismatches in the genotyping primers, suggesting opportunities to revisit and update current sapovirus typing methods.

Genomic Characterization of Three Melon Necrotic Spot Viruses Detected in Human Stool Specimens.

The complete coding sequences of three melon necrotic spot viruses (MNSVs) were obtained from viral metagenomics of stool samples from patients with acute gastroenteritis. These genomes were most similar to Spanish strains sequenced in 2003 and a novel MNSV watermelon strain in 2014.

Complete Genome Sequences of Mumps and Measles Virus Isolates from Three States in the United States.

We report here the full coding sequence of nine paramyxovirus genomes, including two full-length mumps virus genomes (genotypes G and H) and seven measles virus genomes (genotypes B3 and D4, D8, and D9), from respiratory samples of patients from California, Virginia, and Alabama obtained between 2010 and 2014.
