This case study describes findings from an exercise conducted in April 2023 to assess the readiness of the National Quarantine Unit (NQU) and identify opportunities for improvement. 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. Findings showed that collaboration and engagement of local, state, and national organizations increases awareness of novel and emerging high-consequence infectious disease pathogens and enhances capabilities and capacity for patient transport. It also improves timely and efficient diagnostic testing and increases the availability of dedicated assets to support activation and mobilization of the NQU, the Regional Emerging Special Pathogen Treatment Center network, and the future national special pathogen system of care. Given the changing landscape of emerging special pathogens, an objective evaluation of the state of readiness is an essential element of preparedness and response.

The COVID-19 pandemic has underscored the importance of the International Health Regulations (IHR) (2005) in addressing global health emergencies. This review aims to improve healthcare system capabilities, future preparedness, and actions in the Eastern Mediterranean Region, particularly in low-resource areas. The IHR, established in 1969, initially focused on 6 diseases but has since expanded to include a wider range of public health threats. These regulations establish a globally recognized legal framework that is applicable to all 196 states parties, including all 194 World Health Organization member states. The IHR prioritize the prevention, protection, and control of global disease transmission while minimizing unwarranted disruptions to international travel and commerce. Nonetheless, the response to COVID-19 in the Eastern Mediterranean Region revealed a range of deficiencies despite the regulatory strengths. Some countries encountered challenges in fully complying with their IHR obligations, particularly in terms of preparedness, and occasional geopolitical tensions obstructed international collaboration. The pandemic experience underscores the need for improved trust, resource allocation, and regulatory revisions to address upcoming global health challenges. This case study highlights positive aspects of the pandemic response, including the swift exchange of information and global cooperation, while also recognizing shortcomings, such as delays in reporting and unequal vaccine access. In summary, the COVID-19 pandemic underscores the urgency of subsequent updates to the IHR or comparable accords, such as the IHR amendments and the pandemic treaty, to rectify these deficiencies. Updates should place a greater emphasis on transparency, cultivating trust, enhancing preparedness, and establishing mechanisms that incentivize comprehensive compliance among all participating nations.

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. This study reviews the results of a descriptive survey of global HLIUs conducted between December 2022 and February 2023. The purpose of the survey was to identify traits and attributes of global HLIU peers to determine commonalities and differences among the units, identify priorities for increased networking, and inform future activities among global partners. Findings from this survey demonstrate the array of similarities and differences among HLIUs across the globe, indicate potential areas of further investigation, and identify areas in which alignment could be improved and global standards could be created.

The New York City Department of Health and Mental Hygiene and the Greater New York Hospital Association held 3 workshops and 2 follow-up meetings with hospital emergency managers and colleagues to determine hospitals' response actions to a scenario of a 10-kiloton improvised nuclear device detonation. The scenario incorporated 3 zones of damage (moderate, light, and beyond damage zones) and covered the period of 0 to 72 hours postdetonation divided into 3 24-hour operational periods. The Joint Commission's critical emergency areas were used to determine the objectives and response actions that would be initiated. The response actions were motivated by the resource-constrained clinical situation demanding the rationing of supplies and the application of crisis standards of care. Actions included seeking situational awareness concerning the incident and maintaining a safe and secure working environment. Due to the severance of the medical material supply chain and the levels of destruction, inner damage zone hospitals considered termination of operations and evacuation. Beyond damage zone hospitals prepared to receive patients from the inner damage zone facilities. However, these plans would not be fully successful without a significant amount of logistical aid from outside local or regional partners. Four broad planning areas with outside partners emerged from the follow-up meetings: staffing, resupply, communications/situational awareness, and guidance. Dwindling resources will require a plan for rationing and implementing crisis standards of care and maintaining staff morale. Communications efforts need to include a formalized plan with scheduled broadcast times and identified sources of authority for hospitals to acquire and disseminate information. Information about fallout radiation, instructions for measuring contamination, and guidance for triaging and diagnosing acute radiation sickness are also needed.

An important aspect of microbiological surveillance is the ability to access live viruses for microneutralization assays, which enables the study of viral characteristics and mechanisms in vitro and production of positive controls for diagnostic methods. During the COVID-19 pandemic, the Public Health Agency of Sweden established a protocol for the rapid collection of clinical samples and subsequent isolation of novel virus variants.

A high-level isolation unit (HLIU) is a specially designed biocontainment unit for suspected or confirmed high-consequence infectious diseases. For most HLIUs, maintaining readiness during times of inactivity is a challenge. In this case study, we describe a checklist approach to assess HLIU readiness to rapidly operate upon activation. This checklist includes readiness criteria in several domains, such as infrastructure, human resources, and material supplies, that are required to safely activate the unit at any time. The checklist audit tool was derived from a novel activation readiness checklist published by the biocontainment unit at The Johns Hopkins Hospital in Baltimore, Maryland. It was then adapted for the Irish healthcare setting and implemented at the Mater Misericordiae University Hospital, Ireland's current isolation facility. Results from the audit were also used to inform recommendations for the construction of a new HLIU to open in 2025. The audit tool is user friendly, practical, and focuses on the essential elements of readiness to ensure a successful rapid operation.

Infectious disease physicians in England have been diagnosing and managing occasional cases of viral hemorrhagic fever since 1971, including the United Kingdom's first case of Ebola virus disease in 1976. Specialist isolation facilities to provide safe and effective care have been present since that time. Following the emergence of Middle East respiratory syndrome (MERS) in 2012, and the avian influenza A (H7N9) outbreak in 2013, and the 2014-2016 Ebola virus disease outbreak in West Africa, clinical and public health preparedness and response pathways in England have been strengthened for these types of diseases, now called high-consequence infectious diseases (HCIDs). The HCID program, led by NHS England and Public Health England between 2016 and 2018, helped to deliver these enhancements, which have since been used on multiple occasions for new UK cases and outbreaks of MERS, mpox, avian influenza, and Lassa fever. Additionally, HCID pathways were activated for COVID-19 during the first 3 months of 2020, before the pandemic had been declared and little was known about COVID-19 but HCID status had been assigned temporarily to COVID-19 as a precaution. The HCID program also led to the commissioning of a network of new airborne HCID treatment centers in England, to supplement the existing network of contact HCID treatment centers, which includes the United Kingdom's only 2 high-level isolation units. In this case study, the authors describe the airborne and contact HCID treatment center networks in England, including their formation and structures, their approach to safe and effective clinical management of patients with HCIDs in the United Kingdom, and challenges they may face going forward.
