The exercise is part of a multiyear effort to assess the readiness of quarantine and transport capabilities at the NQU through annual workshops, discussion-based exercises, and functional and full-scale exercises. The April 2023 exercise tested interagency coordination and decisionmaking, transport of individuals for monitoring, quarantine unit operations, and escalation of care for symptomatic individuals out of quarantine to high-level isolation units in the United States.

Feasibility Assessment of a Novel Isolation Care Tent in Uganda During the 2022 Outbreak.

This case study describes a feasibility assessment of a novel isolation care tent used in health facilities in Uganda during the 2022 outbreak. The Isolation System for Treatment and Agile Response to High-Risk Infections Model 1B (ISTARI 1B) is a single-occupancy, portable, negative-pressure isolation tent designed for the safe delivery of standard care to patients with a communicable disease, including Ebola disease (Sudan). At the request of the Uganda Ministry of Health, the Makerere University Infectious Diseases Institute and University of Nebraska Medical Center partnered to evaluate 7 health facilities across 4 districts in Uganda for infrastructure, case management, and infection prevention and control (IPC) capacity relevant to isolation care and ISTARI 1B use.

The cardinal rules: Principles of personal protective equipment for high-consequence infectious disease events.

In recognition of an increasing number of high-consequence infectious disease events, a group of subject-matter experts identified core safety principles that can be applied across all donning and doffing protocols for personal protective equipment.

Literature review of physiological strain of personal protective equipment on personnel in the high-consequence infectious disease isolation environment.

Background: Heat strain and dehydration can affect an individual's physical and mental performance. The purpose of this review was to examine the literature for the impact of heat strain on health care workers (HCWs) who care for patients with high-consequence infectious diseases (HCIDs) while wearing personal protective equipment (PPE), discuss the risks of impaired safety caused by heat strain and dehydration in HCID environments, identify attempts to combat PPE-related heat strain, recognize limitations, and provide suggestions for further research.

Methods: A literature search was performed in PubMed or MEDLINE and Google Scholar.

Access, socioeconomic environment, and death from COVID-19 in Nebraska.

Our study assesses whether factors related to healthcare access in the first year of the pandemic affect mortality and length of stay (LOS). Our cohort study examined hospitalized patients at Nebraska Medicine between April and October 2020 who were tested for SARS-CoV-2 and had a charted sepsis related diagnostic code. Multivariate logistic was used to analyze the odds of mortality and linear regression was used to calculate the parameter estimates of LOS associated with COVID-19 status, age, gender, race/ethnicity, median household income, admission month, and residential distance from definitive care.

Avoiding Crisis Conditions in the Healthcare Infrastructure: 2 Case Studies in Statewide Collaboration.

In fall 2020, COVID-19 infections accelerated across the United States. For many states, a surge in COVID-19 cases meant planning for the allocation of scarce resources. Crisis standards of care planning focuses on maintaining high-quality clinical care amid extreme operating conditions.

Treating Workers as Essential Too: An Ethical Framework for Public Health Interventions to Prevent and Control COVID-19 Infections among Meat-processing Facility Workers and Their Communities in the United States.

Meat is a multi-billion-dollar industry that relies on people performing risky physical work inside meat-processing facilities over long shifts in close proximity. These workers are socially disempowered, and many are members of groups beset by historic and ongoing structural discrimination. The combination of working conditions and worker characteristics facilitate the spread of SARS-CoV-2, the virus that causes COVID-19.

Purpose: In 2012, US Marines and Sailors began annual deployments to Australia to participate in joint training exercises with the Australian Defence Force and other partners in the region. During their training, US service members are exposed to a variety of infectious disease threats not normally encountered by American citizens. This paper describes a cohort of US Marines and Sailors enrolled during five rotations to Australia between 2016 and 2020.

The size and culturability of patient-generated SARS-CoV-2 aerosol.

Background: Aerosol transmission of COVID-19 is the subject of ongoing policy debate. Characterizing aerosol produced by people with COVID-19 is critical to understanding the role of aerosols in transmission.

Objective: We investigated the presence of virus in size-fractioned aerosols from six COVID-19 patients admitted into mixed acuity wards in April of 2020.

Leveraging a Preexisting Global Infectious Disease Network for Local Decision Making During a Pandemic.

Emerging infectious disease epidemics require a rapid response from health systems; however, evidence-based consensus guidelines are generally absent early in the course of events. Formed in 2017 by 5 high-level isolation units spanning 3 continents, the experience of the Global Infectious Disease Preparedness Network (GIDPN) early in the course of coronavirus disease 2019 (COVID-19) provides a model for accelerating best practice development and improving decision-making in health emergencies. The network served as a platform for real-time, open and transparent information-sharing during unknowns of an active outbreak by clinicians caring for patients, by researchers conducting clinical trials and transmission and infection prevention studies, and by teams advising local and national policy makers.

Long-Term Assessment of the Effects of COVID-19 and Isolation Care on Survivor Disability and Anxiety.

We conducted an assessment of disability, anxiety, and other life impacts of COVID-19 and isolation care in a unique cohort of individuals. These included both community admissions to a university hospital as well as some of the earliest international aeromedical evacuees. Among an initial 16 COVID-19 survivors that were interviewed 6-12 months following their admission into isolation care, perception of their isolation care experience was related to their reporting of long-term consequences.

Antibacterial use in the age of SARS-CoV-2.

Background: Balancing the use of antibacterial therapy against selection for resistance in this pandemic era has introduced both questions and guidelines. In this project, we explored how prescription of empirical antibacterial therapy differs between those with and without SARS-CoV-2 infection.

Methods: Multivariable logistic regression was used to determine whether COVID-19 status and other factors play a role in the prescription of antibacterial therapy in an inpatient setting at a large referral academic medical centre.

Aerosol and surface contamination of SARS-CoV-2 observed in quarantine and isolation care.

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) originated in Wuhan, China in late 2019, and its resulting coronavirus disease, COVID-19, was declared a pandemic by the World Health Organization on March 11, 2020. The rapid global spread of COVID-19 represents perhaps the most significant public health emergency in a century. As the pandemic progressed, a continued paucity of evidence on routes of SARS-CoV-2 transmission has resulted in shifting infection prevention and control guidelines between classically-defined airborne and droplet precautions.
