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. As initial COVID-19 cases were detected in the United States, RESPTCs provided essential isolation capacity, supplies, and subject matter expertise that allowed for additional time for healthcare systems to prepare. Through the Special Pathogen Research Network, RESPTCs rapidly enrolled patients into early clinical trials. During periods of high community transmission, RESPTCs provided educational, clinical, and logistical support to a wide range of healthcare and nonhealthcare settings. In this article, we describe how NETEC and the RESPTC network leveraged this foundation of special pathogen readiness to strengthen the national healthcare system's response to the COVID-19 pandemic. NETEC and the RESPTC network have proven to be an effective model that can support the national response to future emerging special pathogens.

Capabilities of global high-level isolation units: A pre-workshop survey.

OBJECTIVE: To assess experience, physical infrastructure, and capabilities of high-level isolation units (HLIUs) planning to participate in a 2018 global HLIU workshop hosted by the US National Emerging Special Pathogens Training and Education Center (NETEC). DESIGN: An electronic survey elicited information on general HLIU organization, operating costs, staffing models, and infection control protocols of select global units. SETTING AND PARTICIPANTS: The survey was distributed to site representatives of 22 HLIUs located in the United States, Europe, and Asia; 19 (86%) responded. METHODS: Data were coded and analyzed using descriptive statistics. RESULTS: The mean annual reported budget for the 19 responding units was US$484,615. Most (89%) had treated a suspected or confirmed case of a high-consequence infectious disease. Reported composition of trained teams included a broad range of clinical and nonclinical roles. The mean number of HLIU beds was 6.37 (median, 4; range, 2-20) for adults and 4.23 (median, 2; range, 1-10) for children; however, capacity was dependent on pathogen. CONCLUSIONS: Responding HLIUs represent some of the most experienced HLIUs in the world. Variation in reported unit infrastructure, capabilities, and procedures demonstrate the variety of HLIU approaches. A number of technical questions unique to HLIUs remain unanswered related to physical design, infection prevention and control procedures, and staffing and training. These key areas represent potential focal points for future evidence and practice guidelines. These data are important considerations for hospitals considering the design and development of HLIUs, and there is a need for continued global HLIU collaboration to define best practices.

Serosurvey on healthcare personnel caring for patients with Ebola virus disease and Lassa virus in the United States.

OBJECTIVE: Healthcare personnel (HCP) were recruited to provide serum samples, which were tested for antibodies against Ebola or Lassa virus to evaluate for asymptomatic seroconversion. SETTING: From 2014 to 2016, 4 patients with Ebola virus disease (EVD) and 1 patient with Lassa fever (LF) were treated in the Serious Communicable Diseases Unit (SCDU) at Emory University Hospital. Strict infection control and clinical biosafety practices were implemented to prevent nosocomial transmission of EVD or LF to HCP. PARTICIPANTS: All personnel who entered the SCDU who were required to measure their temperatures and complete a symptom questionnaire twice daily were eligible. RESULTS: No employee developed symptomatic EVD or LF. EVD and LF antibody studies were performed on sera samples from 42 HCP. The 6 participants who had received investigational vaccination with a chimpanzee adenovirus type 3 vectored Ebola glycoprotein vaccine had high antibody titers to Ebola glycoprotein, but none had a response to Ebola nucleoprotein or VP40, or a response to LF antigens. CONCLUSIONS: Patients infected with filoviruses and arenaviruses can be managed successfully without causing occupation-related symptomatic or asymptomatic infections. Meticulous attention to infection control and clinical biosafety practices by highly motivated, trained staff is critical to the safe care of patients with an infection from a special pathogen.

Bioaerosol sampling of a ventilated patient with COVID-19.

Bioaerosol samples were collected in an airborne infection isolation room, bathroom, and anteroom of a ventilated patient with coronavirus disease 2019. Twenty-eight samples were negative for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid, possibly due to the patient being on a closed-circuit ventilator or the efficiency of the air exchanges in the room.

A Novel Approach to Infectious Disease Preparedness: Incorporating Investigational Therapeutics and Research Objectives into Full-Scale Exercises.

The use of investigational therapeutics in the care of patients with Ebola virus disease was documented in the literature following the 2013-2016 outbreak. In order to access these types of therapeutics, facilities must have processes in place to quickly and efficiently activate study protocols, obtain the medications, and administer them in a timely manner. Testing these procedures in advance of a real-world event is crucial to ensuring successful implementation and execution. Drills and exercises are routinely used as part of the emergency preparedness planning process, as they provide a low-risk environment in which to test plans and procedures. Including research activities in full-scale emergency preparedness exercises is a novel approach that should be considered when creating a comprehensive special pathogen program. One important aspect of creating an agile response program is developing and sustaining strong relationships with key collaborators. Including departments not previously engaged in infectious disease preparedness exercises provides a forum to strengthen these relationships, clarify roles, and identify gaps. This article describes the process used to incorporate research-centric objectives focused on the use of investigational therapeutics for Ebola virus disease into a full-scale exercise, the evaluation process used to measure the identified objectives, and the results of the exercise.

Favipiravir and Ribavirin Treatment of Epidemiologically Linked Cases of Lassa Fever.

Two patients with Lassa fever are described who are the first human cases treated with a combination of ribavirin and favipiravir. Both patients survived but developed transaminitis and had prolonged detectable virus RNA in blood and semen, suggesting that the possibility of sexual transmission of Lassa virus should be considered.

The National Ebola Training and Education Center: Preparing the United States for Ebola and Other Special Pathogens.

The National Ebola Training and Education Center (NETEC) was established in 2015 in response to the 2014-2016 Ebola virus disease outbreak in West Africa. The US Department of Health and Human Services office of the Assistant Secretary for Preparedness and Response and the US Centers for Disease Control and Prevention sought to increase the competency of healthcare and public health workers, as well as the capability of healthcare facilities in the United States, to deliver safe, efficient, and effective care to patients infected with Ebola and other special pathogens nationwide. NYC Health + Hospitals/Bellevue, Emory University, and the University of Nebraska Medical Center/Nebraska Medicine were awarded this cooperative agreement, based in part on their experience in safely and successfully evaluating and treating patients with Ebola virus disease in the United States. In 2016, NETEC received a supplemental award to expand on 3 initial primary tasks: (1) develop metrics and conduct peer review assessments; (2) develop and provide educational materials, resources, and tools, including exercise design templates; (3) provide expert training and technical assistance; and, to add a fourth task, create a special pathogens clinical research network.

Ebola or Not? Evaluating the Ill Traveler From Ebola-Affected Countries in West Africa.

Background. The 2014-2015 Ebola epidemic in West Africa had global impact beyond the primarily affected countries of Guinea, Liberia, and Sierra Leone. Other countries, including the United States, encountered numerous patients who arrived from highly affected countries with fever or other signs or symptoms consistent with Ebola virus disease (EVD). Methods. We describe our experience evaluating 25 travelers who met the US Centers for Disease Control and Prevention case definition for a person under investigation (PUI) for EVD from July 20, 2014 to January 28, 2015. All patients were triaged and evaluated under the guidance of institutional protocols to the emergency department, outpatient tropical medicine clinic, or Emory's Ebola treatment unit. Strict attention to infection control and early involvement of public health authorities guided the safe evaluation of these patients. Results. None were diagnosed with EVD. Respiratory illnesses were common, and 8 (32%) PUI were confirmed to have influenza. Four patients (16%) were diagnosed with potentially life-threatening infections or conditions, including 3 with Plasmodium falciparum malaria and 1 with diabetic ketoacidosis. Conclusions. In addition to preparing for potential patients with EVD, Ebola assessment centers should consider other life-threatening conditions requiring urgent treatment, and travelers to affected countries should be strongly advised to seek pretravel counseling. Furthermore, attention to infection control in all aspects of PUI evaluation is paramount and has presented unique challenges. Lessons learned from our evaluation of potential patients with EVD can help inform preparations for future outbreaks of highly pathogenic communicable diseases.

Performance of bedside diagnostic ultrasound in an Ebola isolation unit: the Emory University Hospital experience.

OBJECTIVE: Individuals with Ebola virus disease, a contagious and potentially lethal infection, are now being treated in specialized units in the United States. We describe Emory University's initial experience, current operating procedures, and ongoing planning with diagnostic ultrasound in the isolation unit. CONCLUSION: Ultrasound use has been limited to date. Future planning considerations include deciding what types of ultrasound studies will be performed, which personnel will acquire the images, and which ultrasound machine will be used.

Radiographic imaging for patients with contagious infectious diseases: how to acquire chest radiographs of patients infected with the Ebola virus.

OBJECTIVE: Contagious infectious diseases add a new dimension to radiology and pose many unanswered questions. In particular, what is the safest way to image patients with contagious and potentially lethal infectious diseases? Here, we describe protocols used by Emory University to successfully acquire chest radiographs of patients with Ebola virus disease. CONCLUSION: Radiology departments need to develop new protocols for various modalities used in imaging patients with contagious and potentially lethal infectious diseases.
