Connecting Organizations for Regional Disease Surveillance (CORDS) is an international non-governmental organization focused on information exchange between disease surveillance networks in different areas of the world. By linking regional disease surveillance networks, CORDS builds a trust-based social fabric of experts who share best practices, surveillance tools and strategies, training courses, and innovations. CORDS exemplifies the shifting patterns of international collaboration needed to prevent, detect, and counter all types of biological dangers – not just naturally occurring infectious diseases, but also terrorist threats. Representing a network-of-networks approach, the mission of CORDS is to link regional disease surveillance networks to improve global capacity to respond to infectious diseases. CORDS is an informal governance cooperative with six founding regional disease surveillance networks, with plans to expand; it works in complement and cooperatively with the World Health Organization (WHO), the World Organization for Animal Health (OIE), and the Food and Animal Organization of the United Nations (FAO). As described in detail elsewhere in this special issue of Emerging Health Threats, each regional network is an alliance of a small number of neighboring countries working across national borders to tackle emerging infectious diseases that require unified regional efforts. Here we describe the history, culture and commitment of CORDS; and the novel and necessary role that CORDS serves in the existing international infectious disease surveillance framework.
In the past few decades, one or two new infectious disease threats have emerged every year somewhere on the planet. The vast majority of new human infectious disease threats are zoonotic, meaning that they originate in animals. As we develop more land, mine more of the earth's resources, and hunt and raise more animals for food, we increase our exposure to animal pathogens that have the potential to “jump” the species barrier. Because both people and products are able to transit the globe during the incubation period for many infectious diseases, index cases often occur continents away from where outbreaks originate. Whether it be SARS in travelers (2003), influenza H1N1 in passengers (2009), Nipah virus in exported pigs (1998, 1999), HIV in shipped contaminated Factor VIII (1983), or E. coli in foodstuffs (ongoing), the geographic expanse of infectious diseases is truly boundless. Thus, populations across the globe are at risk of newly arriving infections that may be unfamiliar, difficult to diagnose, and challenging to treat and control (1–3).
At the same time, the increasingly competitive global marketplace has created new trading communities that are more economically integrated than in the past. New regional and cross border trade agreements have contributed to this shift in the trade landscape. The shift is driving many economies to begin to orchestrate their surveillance efforts, especially against infectious disease, with their neighboring trading and travel partners. Countries across the world are self-assembling into regional surveillance networks that do not necessarily operate within the confines of the older geo-political regional boundaries set forth by country membership in the World Health Organization (WHO) (4–6).
This article highlights the work being done by Connecting Organizations for Regional Disease Surveillance (CORDS). CORDS is an international non-governmental organization that links six of these self-assembling regional infectious disease surveillance networks (7–8). Each network is itself an alliance of a small number of neighboring countries working across national borders – sometimes borders in conflict – to tackle infectious disease threats that require unified regional efforts. By linking the networks not only with each other but also with WHO, the World Organisation for Animal Health (OIE), the Food and Agriculture Organization of the United Nations (FAO), and other agencies and institutions involved with disease surveillance, CORDS exemplifies the type of combined vertical plus horizontal international collaboration that will be needed to prevent, detect, and respond to the shifting spectrum of infectious disease threats that are an unfortunate reality in today's “global” world (9–10).
As elaborated throughout this issue, CORDS members regularly collaborate to build national, regional and global capacity while at the same time responding to infectious disease emergencies as they occur. The bonds that are forming within and among the CORDS regional surveillance networks are nurturing not just a cross-border approach to disease surveillance, but also a cross-disciplinary One Health approach. During times of emergency, the personal relationships being nurtured by CORDS and its member networks help to ensure that the joint outbreak investigations and controls are carried out in a timely manner; that the necessary diagnostics and potentially life-saving vaccines and drugs are shared where they are needed; that biological specimens are available for regional laboratory testing; and that appropriate regional travel restriction or other control measures are implemented when the situation demands.
Although this article highlights CORDS and its member networks, many other economies, government agencies, and informal groups have assembled in recent years to collectively combat infectious diseases (11–13). Examples include the West African Health Organisation (WAHO), the Pacific Public Health Surveillance Network (PPHSN), the Association of Southeast Asian Nations (ASEAN) Plus Three (China, Japan, Korea) Field Epidemiology Training Network (ASEAN+3 FETN), the Asia-Pacific Economic Cooperation (APEC) and APEC Emerging Infections Network (APEC EINet); the Caribbean Epidemiology Centre (CAREC); ProMED-mail; and the Global Outbreak Alert and Response Network (GOARN). See Ref. 11 in this issue for a discussion of WAHO, PPHSN, and ASEAN+3 FETN.
In 2007, the Rockefeller Foundation and Nuclear Threat Initiative (NTI) convened infectious disease surveillance representatives and other experts from across the world to share best practices and lessons learned in disease surveillance. Attendees of the meeting, which was held at the Rockefeller Foundation Bellagio Conference Center, Italy, were asked to recommend actions to advance the global capacity for public health surveillance and reduce the threat of infectious diseases, with a focus on the needs of developing countries. The resulting Bellagio Call for Action addressed three “vital concerns”: (i) the need to build surveillance capacity, especially human and laboratory capacity, but also cross-border collaborative capacity; (ii) the need to develop and employ appropriate information and data-sharing technology to facilitate timely communication during times of emergency; and (iii) the need for a flexible approach to governance among the growing number of regional infectious disease surveillance networks that are self-assembling worldwide (14).
At the same time, regional disease surveillance networks themselves were recognizing a shared incentive to improve early detection and outbreak investigation and response. Driven by that incentive and with the support and partnership of NTI, the Rockefeller Foundation, Peter G. Peterson Foundation, the Fondation Mérieux, and the Skoll Global Threats Fund, the leaders of six existing regional disease surveillance networks founded CORDS. The six networks, all of which are described in detail elsewhere in this issue (see also Table 1) are: Mekong Basin Disease Surveillance Network (MBDS) (15), East African Integrated Disease Surveillance Network (EAIDSNet) (16), South Eastern European Health Network (SEEHN) (17), Middle East Consortium on Infectious Disease Surveillance (MECIDS) (18), Asian Partnership on Emerging Infectious Disease Research (APEIR) (19), and Southern African Centre for Infectious Disease Surveillance (SACIDS) (20). During CORDS's early years, NTI served the role of interim secretariat; Fondation Mérieux provided a home in Annecy, France, for convening CORDS. CORDS was formally created as a non-governmental organization in Lyon, France, in 2012.
Representing a network-of-networks approach, CORDS enables networks to interact not only with each other, but also with the WHO, OIE, FAO, and other surveillance partners. CORDS also partners with other public and private sector actors who share common health security goals (6, 7, 21, 22); and with individual professionals.
CORDS operates as a community of practice: a learning partnership among people who share a common concern, in this case improving infectious disease surveillance capacity, and who come together regularly to learn how to do it better (23). CORDS networks regularly meet to exchange information and innovations (e.g., new data-sharing tools); participate in training courses and learn through case studies; and jointly build surveillance capacity. By providing a central forum for peers from different parts of the world to share expertise and best practices and, over time, nurture trust, CORDS fosters the development of professional collaborations and provides regular opportunities for joint learning and technical exchanges. CORDS strengthens the dialogue not just among public health, veterinary, and wildlife professionals from different regions of the world, but also between those professionals and WHO, OIE, and FAO.
The vision of CORDS is “a world united against infectious diseases.” Its mission is “to link regional disease surveillance networks and improve global capacity to respond to infectious diseases.” CORDS has four strategic objectives:
While CORDS is still early in its development, already its member networks have demonstrated that even in parts of the world historically (e.g., Southeast Asia) or currently rife with conflict (e.g., Middle East), public health and veterinary experts and officials from neighboring countries can come together in emergency situations and successfully coordinate efforts to prevent the spread of infectious disease (4–6, 24). The key to success is trust. Multi-country disease surveillance networks are successful only when individual experts from across countries and regions develop trust-based relationships that support the comfortable and timely exchange of views and information. For example, MBDS is a network of trust-based social relationships that have developed over time and did not exist thirteen years ago. As the network matured and as disease surveillance and control epidemiologists and other professionals from neighboring countries routinely worked together on joint surveillance goals, the sharing of data, tools, and innovative ideas and approaches increased substantially. CORDS is committed to nurturing a trust-based culture that encourages the secure and timely sharing of information and best practices between disease surveillance experts from across its member networks.
The operational philosophy of CORDS is to be small, nimble, and supportive of member networks. In accord with the trust-based and collaborative culture of CORDS, the CORDS Executive Board operates on consensus when it establishes the objectives, policies, and plans of action for the organization. CORDS rotates leadership such that all involved networks will have the opportunity for one of their representatives to serve as Chair of the Executive Board (EB).
Among the most obvious benefits of CORDS membership is that participating regional surveillance networks – and the countries linked by those networks – are improving national capacities in compliance with the revised International Health Regulations (IHR). The IHR provides a framework for improved international public health security by strengthening global surveillance, improving communication between WHO and member states, and setting ground rules to address national public health emergencies of international concern (25). It is a set of legally binding requirements agreed upon by the 194 member states to help structure a world that is on alert and prepared to respond to the threat of infectious epidemics. Many public health experts, including WHO leadership, have called for additional strategies to complement WHO efforts to build the mandated national capacities for compliance (5, 26–28). Indeed, the IHR itself includes provision for member states to seek technical assistance from WHO (29). However, WHO has limited funding and capacity to help countries meet capacity levels to detect and respond to cross-border threats. CORDS complements WHO efforts by helping regional networks to collectively built mandated core surveillance capacities through the sharing of information and standard protocols and the channeling of resources. WHO has been participating in CORDS activities and collaborating closely with the regional networks. WHO representatives regularly attend CORDS meetings; CORDS has held joint One Health meetings with WHO; and WHO has worked with both CORDS and its regional network members to build laboratory capacity.
CORDS fosters the sharing of information with other global infectious disease surveillance partners in addition to WHO, including OIE and FAO. Both are observers to the CORDS Executive Board. These collaborations are important to improving coordination between public health, veterinary, and wildlife surveillance and achieving the One Health strategic objective of CORDS.
Like its network members, CORDS cultivates trust-based relationships that enable neighboring countries to communicate and interact with each other during times of crisis more quickly and nimbly than is sometimes possible within the vertical and geopolitical structure of WHO. The vertical bureaucracy of WHO and member states dictates that permission from a top administrative unit is usually required to allow the sharing of information. The geopolitical structure of WHO is such that a number of neighboring countries are in different regions of WHO, which makes it difficult to communicate essential outbreak information via WHO channels in a timely manner. For example, Myanmar and Thailand are members of the South East Asia Region of WHO, while their neighbors China, Laos PDR, Cambodia, and Vietnam are members of the Western Pacific Region. Instead of relying solely on formal WHO communication channels during emergencies, neighboring countries are often able to launch more effective responses when they communicate directly with each other while at the same time communicating with WHO. The informal reporting structures of the regional disease surveillance networks featured here facilitate real-time information exchange and rapid and effective joint outbreak investigations. Moreover, CORDS networks also extend across non-member states.
The H5N1 pandemic threat in 2007 was a good example of informal communication facilitating a joint outbreak investigation between two countries in different WHO regions (15). The Thai team informed the Laos team immediately after the index case, in a Laotian girl, was diagnosed in Nong Khai province in Thailand, opposite the capital of Laos PDR, Vientiane. The Laos team immediately crossed the border to visit the girl, collect specimens, and start an investigation. The next day experts from the two countries conducted a joint outbreak investigation in the village where the girl resided, while at the same time reporting to WHO. This timely joint response was based on trust-based collegial relationships, without any requirement for permission from top leaders.
The trust-based social fabric being cultivated by CORDS and its member networks also helps to tackle the challenge of disease under-reporting, as well as wrongful accusations about neighboring WHO Member States. WHO is still limited in how it can intervene when a country does not report a disease threat (30).
CORDS cultivates networks of professionals who have the collective strength to translate information into near-real-time action during emergency situations. The value of CORDS ranges from the potential (e.g., knowledge capital, social capital, learning capital) to the applied (e.g., changes in practice based on CORDS interactions) to the realized (improved performance). Text Box 1 outlines examples of the value of CORDS.
The collaborative capacity to immediately detect, respond, and effectively control the occurrence of infectious diseases and prevent them from becoming pandemics is of utmost importance. While the IHR provides an official platform for infectious disease surveillance experts to communicate essential information, the vertical structure of WHO and the outdated geopolitical boundaries of the WHO regions create obstacles for infectious disease surveillance practitioners and other professionals to communicate in a timely manner during crises. Ensuring that a robust response to global infectious disease threats is present anywhere and everywhere at all times requires combining formal WHO and other surveillance mechanisms with the nimble nature of the regional networks linked by CORDS and of CORDS itself. The horizontal, semi-formal, trust-based relationships among regional disease surveillance networks being cultivated by CORDS interweave with the more formal, vertical relationships between Member States and WHO, OIE and FAO to form a global disease surveillance fabric that promotes more effective actions than would otherwise be possible. By pursuing a common vision where disease no longer threatens the security and prosperity of nations, CORDS is revitalizing international efforts against biological threats and helping to weave “A World United Against Infectious Diseases.”
