The Centers for Disease Control and Prevention's (CDC) Division of Global Migration and Quarantine (DGMQ) protects U.S. communities from the introduction, transmission, and spread of communicable diseases by anticipating, preventing, detecting, and responding to public health threats.
The emergence of the 2019 novel coronavirus (COVID-19) pandemic prompted the CDC to request an external assessment of the role of DGMQ and the federal quarantine stations to mitigate the risk of onward communicable disease transmission given the changes in the global environment, including large increases in international travel, threats posed by emerging infections, and the movement of animals and cargo.

Global health threats have been steadily increasing in frequency over the last several years. The CDC’s Division of Global Migration and Quarantine (DGMQ) works to guard the nation’s health by preventing the spread of communicable diseases in the United States. DGMQ includes a national network of quarantine stations, where officials respond to public health concerns at airports, sea ports, and land border crossings.
Quarantine stations have 4 major priorities:
Respond to reports of illnesses on airplanes, maritime vessels, and at land-border crossings
Monitor health of travelers, alert local health departments on health issues that require follow-up, and provide travelers with essential health information
Inspect animals, products, and cargo for potential threats to human health
Build partnerships for disease surveillance and control
Our world is more interconnected than ever before, creating more opportunities for disease spread. The rapid succession of outbreaks such as Ebola, Zika, and COVID-19 has created a steady stream of disease events, all requiring a surge of resources in response. Public health emergencies are becoming a norm rather than an exception. A modern DGMQ must be equipped to properly meet these challenges in a changing world.
Following a surge in DGMQ’s responsibilities after the onset of the COVID-19 pandemic, the National Academies of Sciences, Engineering, and Medicine was consulted to assess quarantine station effectiveness. With mounting demands resulting from increased frequency of public health emergencies over the past several years, DGMQ requires more resources, modernized technology, and updated legal structures to continue safeguarding public health at home and abroad.
Public health experts from around the world were invited to give their perspectives on the purpose of quarantine networks.
The experts discussed examples of successful interventions that were implemented during the COVID-19 pandemic including procedures taken for screening, isolation, and quarantine of incoming passengers in their response efforts.
DGMQ’s structure and function relies on five key domains. Strengthening the organization’s capacity, disease control functions, use of technology, and partnerships can greatly increase its efficiency. Modernizing the legal framework will also enable DGMQ to carry out its work more effectively.
Organizational capacity refers to an organization’s ability to perform its work and use its resources effectively. The DGMQ’s organizational capacity can be strengthened by addressing challenges in the areas of finances, workforce, and culture. Building a more sustainable financing structure can allow the DGMQ to better carry out its mission and increase workforce potential. Enhancing DGMQ institutional culture, including opportunities for workforce development, can also strengthen the organization.
The U.S. Department of Health and Human Services, especially including the Centers for Disease Control and Prevention, should ensure that the DGMQ has the necessary financial and personnel resources, an effective organizational structure, and optimal infrastructure to effectively meet its responsibilities, execute its growing volume of work, and achieve its mission.
To implement this recommendation, the DGMQ needs to specifically act and resolve the following issues:
The DGMQ should create an effective and innovative quarantine-station model that matches the expanding and changing needs of a global, mobile world and augments its work in a progressively challenging infectious disease environment.
To achieve this recommendation, the DGMQ needs to implement these specific steps:
Over the past two decades, the pace and variance of global infectious disease emergence has been accelerating at an alarming rate. This likely reflects a range of factors, including mass travel and migration, close animal/human interchange, and climate change. The DGMQ requires access to resources and tools for disease control that can be tailored to the specific threats. Key lessons learned from COVID-19 and other disease mitigation strategies can be leveraged to guide policy decisions to minimize risk of disease spread within the United States.
The DGMQ should develop detailed operational plans and playbooks based on the most concerning and likely scenarios for transmissible disease threats.
The DGMQ, in coordination with appropriate federal partners for implementation, should develop detailed operational plans for large-scale isolation and quarantine needs for future emergencies. These operational plans should be informed by the lessons learned during the initial response to COVID-19. Critical issues to address include:
The DGMQ/CDC should commission an external formal evaluation and/or a modeling study of the effectiveness of travel restrictions and active screening/monitoring of all international travelers in preventing and mitigating disease transmission in the United States during both the current COVID-19 pandemic and the 2014–2015 Ebola outbreaks in West Africa. The formal evaluation should include psychological benefits, political implications, unintended consequences of screening, resources required, and burden placed on state and local jurisdictions. These findings should be used to inform plans detailing when such measures should be considered in the future and to specify the types of pathogens and scenarios that warrant these measures. The latter criteria might include incubation period, timing of infectiousness related to symptom onset, proportion of asymptomatic infections, size of traveler population that would require monitoring, technological ease and cost of monitoring, severity of illness, and reasonable ability to provide or implement countermeasures.
Innovative technologies can contribute to scalable approaches to disease control strategies for large number of incoming travelers at borders and points of entry. The data collected using these technologies and other novel data streams can be used for a broad range of infection control purposes, including (1) contact tracing and proximity tracking to identify and monitor individuals potentially exposed to pathogens; (2) symptom reporting, monitoring, and tracking; (3) digital health certification, and (3) situational awareness and rapid epidemic intelligence.
The DGMQ should increase and improve the use of innovative technology to aid in outbreak detection and response and to mitigate disease transmission. The DGMQ should improve readiness and develop flexible and targeted strategies for disease control at the border. The DGMQ should incorporate and improve on the use of digital technologies to gather health data from travelers, trace transmission, and alert travelers to exposures. These practices will also allow the development of scalable approaches to disease control strategies for large numbers of incoming travelers.
The DGMQ should support the adoption of the Office of the National Coordinator for Health Information (ONC) roadmap by health care and public health practitioners. The DGMQ should work with the ONC to facilitate the ONC roadmap and interoperability networks. Connectathons—events that allow providers, organizations, or other implementers to learn from developers, conduct testing, and practice exchanging data asynchronously across agencies—are an example of how this could occur. As health information technology developers continue to increase functionality in mobile health applications and electronic health records, the DGMQ should identify gaps and opportunities in legislation and regulation to support the proper use and transfer of information across data systems.
The DGMQ should ensure that all uses of digital technologies, novel data streams, and interoperative public health information systems follow a careful consideration of their ethical aspects and that all actions are in accordance with existing regulations for the protection of personal data. In order to achieve this, the DGMQ should put an oversight structure in place.
Partnerships are critical to the DGMQ’s mission. The division works with both domestic and international partners in government and the private sector, including other nation’s quarantine and disease control or¬ganizations; U.S. federal agencies; state, tribal, local, and territorial (STLT) agencies; and private-sector industries. The COVID-19 pandemic has revealed opportunities to strengthen these relationships to facilitate coordination for future events. Fostering trust and strengthening DGMQ’s functional working relationships across agencies and sectors is of critical importance to effectively counter future infectious disease threats.
The DGMQ should strengthen partnerships through defined and planned activities that enhance working relationships and continue to build trust.
To do so, the DGMQ should implement these specific measures:
The DGMQ should modernize health communication efforts with and for travelers to improve public understanding of disease control efforts as well as compliance.
The COVID-19 pandemic displayed the need for modernization of public health legal authorities. The CDC has broad regulatory authority to control the introduction and interstate spread of communicable diseases in the United States. During the COVID-19 pandemic, the DGMQ has exercised powers granted to the CDC under the Public Health Service Act (PHSA) of 1944 by taking actions such as (1) testing, temporarily detaining, and releasing persons entering the United States who are suspected of carrying certain communicable diseases, (2) issuing federal isolation and quarantine orders, and (3) restricting importation of animals or other items that may pose public health threats. Reform of laws and regulations are needed to modernize the CDC’s authorities, and to ensure it has the powers required to safeguard the American public.
Congress should improve the legal authority and flexibility of the CDC in responding to public health threats by modernizing and improving the 1944 Public Health Service Act in several ways:
With large increases in international travel and threats posed by emerging infections, the roles of DGMQ and the federal quarantine station network are more important than ever. Congress should modernize the PHSA, which was enacted before the era of mass travel, migration, trade, and close animal–human interchange. Doing so will enable CDC to implement measures to improve its infrastructure, workforce, data systems, and ability to safeguard the public. The COVID-19 pandemic also saw a proliferation of technological advancements and introduced a range of mitigation strategies for reducing the transmission of the virus nationally and globally. DGMQ should be provided the funding and regulatory authority it needs to implement these effective interventions. DGMQ should also strengthen its partnerships to facilitate coordination during future emergencies and modernize health communication efforts with travelers to improve compliance and public understanding of disease control efforts.
