Global High-Consequence Infectious Disease Readiness and Response: An Inventory of High-Level Isolation Units.

High-level isolation units (HLIUs) are facilities strategically outfitted to receive patients with suspected or confirmed high-consequence infectious diseases (HCIDs). Although most HCID outbreaks occur in low- and middle-income countries, global travel and migration and the deployment of healthcare workers to global outbreaks have led to the occurrence of HCIDs in high-income countries that requires the activation of an HLIU. Despite the existence of HLIUs worldwide, there has been little collaboration between units at the international level.

High-Level Isolation: A Landscape Analysis of Global Capabilities and Opportunities to Advance the Field.

High-level isolation units (HLIUs) have been established by countries to provide safe and optimal medical care for patients with high-consequence infectious diseases. We aimed to identify global high-level isolation capabilities and determine gaps and priorities of global HLIUs, using a multiple method approach that included a systematic review of published and gray literature and a review of Joint External Evaluations and Global Health Security Index reports from 112 countries. A follow-up electronic survey was distributed to identified HLIUs.

The Importance of Networks and Relationships: Leveraging the Biocontainment Unit Leadership Workgroup for Special Pathogen Outbreak Response.

Developing and sustaining relationships and networks before an emergency occurs is crucial. The Biocontainment Unit Leadership Workgroup is a consortium of the 13 Regional Emerging Special Pathogen Treatment Centers in the United States. Established in 2017, the volunteer-based workgroup is composed of operational leaders dedicated to maintaining readiness for special pathogen care.

Building a biocontainment unit: Infrastructure and organizational experiences of the 13 regional biocontainment units in the United States.

In the United States, the system for special pathogen patient care incorporates a network of federally funded US biocontainment units that maintain operational readiness to care for patients afflicted by high-consequence infectious diseases (HCIDs). This network has expanded in number of facilities and in scope, serving as a regional resource for special pathogen preparedness. Lessons learned for maintaining these units are shared with the intent of informing new and existing biocontainment units.

Therapeutics Pipeline.

Children have unique physiologic, developmental, and psychosocial needs and unique vulnerabilities, making them a challenging population for which to develop therapeutics. This is particularly apparent in the urgent and chaotic environment of a pandemic or outbreak. Advances in the development of medical countermeasures (MCMs) for pediatric populations have grown substantially over the last decade, and the coronavirus disease 2019 pandemic forced advancements in how we approach pediatric MCM development.

Effect of human H3N2 influenza virus reassortment on influenza incidence and severity during the 2017-18 influenza season in the USA: a retrospective observational genomic analysis.

Background: During the 2017-18 influenza season in the USA, there was a high incidence of influenza illness and mortality. However, no apparent antigenic change was identified in the dominant H3N2 viruses, and the severity of the season could not be solely attributed to a vaccine mismatch. We aimed to investigate whether the altered virus properties resulting from gene reassortment were underlying causes of the increased case number and disease severity associated with the 2017-18 influenza season.

Select Agent Regulatory Challenges in a Patient Care Setting: Review and Recommendations.

The Federal Select Agent Program ensures the safe and secure possession, use, and transfer of biological select agents and toxins through the select agent regulations (42 CFR §73, 7 CFR §331, and 9 CFR §121). These regulations are primarily written for interpretation by diagnostic and research laboratories, with limited text pertaining to the care of individuals infected with a select agent. The regulations applicable to patient care settings are ambiguous, resulting in challenges with regulatory compliance.

Information Challenges Associated With Accessing and Sharing of Patient Information in Disasters: A Qualitative Analysis.

As disasters increase in frequency and severity, so too does the health impact on affected populations. Disasters exacerbate the already challenging health information-sharing landscape. A reduced capacity to access and share patient information may have negative impacts on providers' ability to care for patients individually and to address disaster health outcomes at the population level.

A narrative review of high-level isolation unit operational and infrastructure features.

High-level isolation units (HLIUs) are specially designed facilities for care and management of patients with suspected or confirmed high-consequence infectious diseases (HCIDs), equipped with unique infrastructure and operational features. While individual HLIUs have published on their experiences caring for patients with HCIDs and two previous HLIU consensus efforts have outlined key components of HLIUs, we aimed to summarise the existing literature that describes best practices, challenges and core features of these specialised facilities. A narrative review of the literature was conducted using keywords associated with HLIUs and HCIDs.

Challenges and Approaches to High-Level Isolation Unit Staffing and Just-in-Time Training: A Meeting Report.

In November 2022, the National Emerging Special Pathogens Training and Education Center hosted a virtual session with global high-level isolation unit (HLIU) representatives to discuss HLIU staffing challenges and approaches. Takeaways are relevant to healthcare institutions seeking solutions to recruit and retain their healthcare workforce amid unprecedented global staffing shortages.

Point-of-Care Lung Ultrasound Predicts Severe Disease and Death Due to COVID-19: A Prospective Cohort Study.

Unlabelled: The clinical utility of point-of-care lung ultrasound (LUS) among hospitalized patients with COVID-19 is unclear.

Design: Prospective cohort study.

Setting: A large tertiary care center in Maryland, between April 2020 and September 2021.

The Evolution of the National Special Pathogen System of Care.

Infectious disease outbreaks and pandemics have repeatedly threatened public health and have severely strained healthcare delivery systems throughout the past century. Pathogens causing respiratory illness, such as influenza viruses and coronaviruses, as well as the highly communicable viral hemorrhagic fevers, pose a large threat to the healthcare delivery system in the United States and worldwide. Through the Hospital Preparedness Program, within the US Department of Health and Human Services Office of the Assistant Secretary for Preparedness and Response, a nationwide Regional Ebola Treatment Network (RETN) was developed, building upon a state- and jurisdiction-based tiered hospital approach.

Developing a Rapid Response Single IRB Model for Conducting Research During a Public Health Emergency.

Research is foundational for evidence-based management of patients. Clinical research, however, takes time to plan, conduct, and disseminate-a luxury that is rarely available during a public health emergency. The University of Nebraska Medical Center (UNMC) developed a single institutional review board (IRB), with a vision to establish a rapid review resource for a network focused on clinical research of emerging pathogens in the United States.

Prepared to Act: Lessons Learned by the Special Pathogens Research Network, Based on Collaborations with the NIAID-Led Adaptive COVID-19 Treatment Trial.

The need for well-controlled clinical trials is fundamental to advancing medicine. Care should be taken to maintain high standards in trial design and conduct even during emergency medical events such as an infectious disease outbreak. In 2020, SARS-CoV-2 emerged and rapidly impacted populations around the globe.

Contributions of the Regional Emerging Special Pathogen Treatment Centers to the US COVID-19 Pandemic Response.

The National Emerging Special Pathogens Training and Education Center (NETEC) was established in 2015 to improve the capabilities of healthcare facilities to provide safe and effective care to patients with Ebola and other special pathogens in the United States. Through NETEC, a collaborative network of 10 Regional Emerging Special Pathogen Treatment Centers (RESPTCs) undertook readiness activities that included potential respiratory pathogens. These preparations, which took place before the COVID-19 pandemic, established a foundation of readiness that enabled RESPTCs to play a pivotal role in the US COVID-19 pandemic response.

Opportunity Among Disaster: Reflecting on 2 Disaster Scenarios During the COVID-19 Pandemic.

Maintaining a public health emergency response for a sustained period of time requires availability of resources, physical and information technology infrastructure, and human capital. What perhaps is unprecedented is a medical center experiencing multiple disasters simultaneously. In this case study, the authors describe 2 separate disaster events experienced during the ongoing COVID-19 pandemic: (1) a cyberattack at Nebraska Medicine in Omaha, Nebraska, and (2) civil unrest following the murder of George Floyd in Minneapolis, Minnesota.

IgM anti-ACE2 autoantibodies in severe COVID-19 activate complement and perturb vascular endothelial function.

BackgroundSome clinical features of severe COVID-19 represent blood vessel damage induced by activation of host immune responses initiated by the coronavirus SARS-CoV-2. We hypothesized autoantibodies against angiotensin-converting enzyme 2 (ACE2), the SARS-CoV-2 receptor expressed on vascular endothelium, are generated during COVID-19 and are of mechanistic importance.MethodsIn an opportunity sample of 118 COVID-19 inpatients, autoantibodies recognizing ACE2 were detected by ELISA.

Impact of coinfection status and comorbidity on disease severity in adult emergency department patients with influenza B.

Background: Influenza B accounts for approximately one fourth of the seasonal influenza burden. However, research on the importance of influenza B has received less attention compared to influenza A. We sought to describe the association of both coinfections and comorbidities with disease severity among adults presenting to emergency departments (ED) with influenza B.

Distinct Cytokine and Chemokine Dysregulation in Hospitalized Children With Acute Coronavirus Disease 2019 and Multisystem Inflammatory Syndrome With Similar Levels of Nasopharyngeal Severe Acute Respiratory Syndrome Coronavirus 2 Shedding.

Background: Multisystem inflammatory syndrome in children (MIS-C) is a severe clinical phenotype of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection that remains poorly understood.

Methods: Hospitalized children <18 years of age with suspected coronavirus disease 2019 (COVID-19) (N = 53) were recruited into a prospective cohort study; 32 had confirmed COVID-19, with 16 meeting the US Centers for Disease Control criteria for MIS-C. Differences in nasopharyngeal viral ribonucleic acid (RNA) levels, SARS-CoV-2 seropositivity, and cytokine/chemokine profiles were examined, including after adjustments for age and sex.

Nosocomial Respiratory Infections in a Rural Zambian Hospital.

The burden of nosocomial respiratory infections in rural southern Africa is poorly understood. We established a surveillance program at a rural Zambian hospital to detect influenza-like illness (ILI) and respiratory infections among hospitalized patients and a cohort of healthcare workers (HCWs). Nasopharyngeal specimens from symptomatic patients and HCWs underwent broadly multiplexed molecular testing to detect viruses and atypical bacteria.
