The rapid global spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in 2020 highlighted the critical role of diagnostics early in the pandemic to understanding the epidemiology of the virus. As a natural extension of Abbott's work in diagnostics, virus discovery, and virus surveillance, the Abbott Pandemic Defense Coalition (APDC) was launched in early 2021. The APDC is a global, multi-sector scientific and public health partnership whose primary objective is the early detection and mitigation of infectious disease threats of pandemic potential. As of January 2022, the APDC network has partners on 5 continents including academic institutions, governmental and non-governmental organizations. A novel element of the APDC is the capacity for early development and rapid deployment of scalable, quality diagnostics targeting newly identified pathogens of pandemic potential. extension of Abbott's work in diagnostics, virus discovery, and virus surveillance, the Abbott Pandemic Defense Coalition (APDC) was launched in early 2021.

As of January 2022, the APDC network has partners on 5 continents including academic institutions, governmental and non-governmental organizations. A novel element of the APDC is the capacity for early development and rapid deployment of scalable, quality diagnostics targeting newly identified pathogens of pandemic potential. In recent decades, the world has experienced the emergence and reemergence of numerous infectious disease threats. Viruses originating from animal reservoirs, such as human (Morens et al. 2020) . Globalization, international travel, displacement of peoples, changes in the environment, and encroachment of humans into natural habitats are all factors contributing to outbreaks and facilitating their global spread (Morens et al. 2020) . International capacity to respond to emerging disease threats was tested most recently with the emergence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). One success in the response to SARS-CoV-2 was the unprecedented development of several safe and effective vaccines less than one year following SARS-CoV-2 genetic sequence becoming available (US Government Accountability Office 2021). This success can be attributed in large part to United States government funding made available through Operation WARP Speed, mitigating the financial risks to the pharmaceutical industry in vaccine development. In contrast, diagnostics, the "first line of defense" in the response to SARS-CoV-2, were developed by industry with limited government support. While development of diagnostics for SARS-CoV-2 has been a success story as well, a public private global disease surveillance network could have potentially helped identify SARS-CoV-2 earlier and/or understand the epidemiology of the virus (e.g., person-to-person spread, asymptomatic infections) earlier resulting in hundreds of thousands of lives saved. In 2005, amid growing concerns about global health security and preparedness, and in order to engage governments and ministries of health in pandemic preparedness and control, the World Health Organization (WHO) and member states formulated and adopted revised International Health Regulations (IHR) (Gostin and Katz 2016) . The IHR mandate that countries develop and maintain defined core capacities for national surveillance and response to diseases of epidemic potential. The IHR highlights the global importance placed on early recognition of disease events so that measures can be taken promptly to control the threat at its source before the disease can spread to other countries. SARS-CoV-2, with its rapid global spread, clearly exposed this preparedness gap. The Abbott Pandemic Defense Coalition (APDC) aims to support the IHR and narrow this gap in early discovery and detection of emerging pathogens and diagnostics availability, in preparation for the next pandemic. In addition to pathogen discovery, a novel and core tenet of the coalition includes the early and scalable development and rapid deployment of quality diagnostics for emerging infectious disease threats. Early distribution of diagnostics may provide the world with the ability for more timely understanding of the epidemiology and spread of the next pandemic-key to mitigation and control efforts, including preventive (including non-pharmaceutical) interventions, therapeutics, and vaccine development. More than 60 percent of the world's blood supply is screened through Abbott instruments, and Abbott has been producing blood screening technologies for more than 40 years (Abbott Diagnostics 2021a). To ensure the safety of the blood supply and accuracy of diagnostic tests for infectious diseases, Abbott has been conducting global surveillance of known infectious diseases since 1994 with a focus on highly diverse pathogens, including HIV, hepatitis B virus (HBV), and hepatitis C virus (HCV) (Abbott Diagnostics 2021b). The aim of this program is to ensure that variant and recombinant strains do not escape detection. This research program has not only helped ensure a safe blood supply, but has also led to the discovery of new, rare strains of HIV-1 (Rodgers et al. 2017; Yamaguchi et al. 2020 ) and identified a group of HIV elite controllers in the Democratic Republic of Congo (DRC) ). In addition, the Abbott Global Surveillance Program has also supported important public health efforts including viral hepatitis research in Cameroon where a previously unrecognized, large burden of hepatitis D virus (HDV) among persons with HBV infection was discovered (Butler et al. 2018) , and HCV elimination efforts in Georgia and in Pakistan (Abbott Laboratories 2020; Abid et al. 2021) . A natural extension of this work is the Virus Discovery Program, wherein specimens from individuals with illnesses of unknown etiology are characterized by metagenomic nextgeneration sequencing for known pathogens and potentially novel viruses. The discovery of human pegivirus-2 (HPgV-2) (Berg et al. 2015) led to development of molecular and serologic diagnostic tests and the launch of a global effort to describe the epidemiology of the virus (Coller et al. 2016; Frankel et al. 2017 ). These studies found HPgV-2 to be a blood borne virus associated with HCV and may result in chronic infection, although no discernible threat to human health has been identified (Berg et al. 2015; Kandathil et al. 2017 ). This successful industry-academia collaboration illustrated the cascade from discovery to test development to translational research needed to understand the nature of the discovery, a model which serves as the foundation for the APDC. In addition, since 2020, Abbott has expended considerable resources in developing and launching SARS-CoV-2 diagnostics, launching 12 tests world-wide, including molecular, antigen, and antibody detection tests (Abbott Laboratories 2021). Surveillance for SARS-CoV-2 has been woven into Abbott's global surveillance efforts, including monitoring for new variants (Mary A Rodgers 2021) . These efforts have allowed Abbott to respond quickly to the evolving SAR-CoV-2 pandemic, ensuring the development of critical diagnostics and contributing to the understanding and detection of variant strains. The Abbott Pandemic Defense Coalition (APDC) is a first-of-its-kind global scientific and public health partnership with the goals of early detection and rapid response to future pandemic threats. By connecting global centers of excellence with expertise in infectious diseases, laboratory testing, genetic sequencing and epidemiology with industry, the program aims to identify new pathogens, determine their potential for pandemic spread, rapidly develop and deploy new diagnostic testing if indicated, and assess public health impact in near real-time. Including Abbott, there are currently 14 APDC partners on 5 continents (Figure 1 ). The APDC network shares expertise in epidemiology, diagnostics, next generation sequencing (NGS), and bioinformatics for investigation of emerging pathogens. This capacity building will facilitate pathogen discovery and surveillance in the country and region where institutions are located. Collaboration with sister institutions within the network will allow for timely investigation and communications with the WHO, CDC, and other public health institutions, enabling early response to potential threats. Further, the APDC partners will benefit from shared experiences and opportunities to collaborate on infectious disease research across the network. Beyond pathogen discovery, priority activities will include SARS-CoV-2 variant surveillance, bloodborne pathogen surveillance, and support for assay development and quality assurance; table 1 summarizes the goals and activities of the APDC. For emerging pathogen discovery, data collection will be harmonized across the APDC, facilitating collaborative research and analysis of findings. Case definitions for acute febrile illness (AFI), influenza-like illness (ILI), severe acute respiratory infection (SARI) and other syndromes of interest will be incorporated. Clinical assessment will be conducted and include diagnostic testing for a range of bacterial, parasitic, mycotic, and viral pathogens as well as noninfectious etiologies. Case-patients without a recognized etiology will be enrolled into the discovery program where demographic, clinical and epidemiologic data will be collected, anonymized, and entered into a centralized, cloud-based database. Enrolled patients will be followed up through hospitalization to gather key laboratory and clinical outcomes (e.g. diagnostic test results, specimen collection, imaging results, admission to the intensive care unit, use of mechanical ventilation, in-hospital death). Appropriate specimens will be collected and stored at -70° C for NGS or other analyses. Institutions will be supported by advanced bioinformatics technology and specimen repositories will be created, with the goal of sharing and cross referencing between partners. The network will therefore provide access to geographically diverse specimens as member sites leverage relationships with local hospitals and clinics to enroll appropriate case-patients beyond their institutions. (TEPHINET) to support epidemiologic capacity in pandemic preparedness in low-and middleincome countries (LMICs). TEPHINET is a global network of 75 Field Epidemiology Training Centers for Disease Control and Prevention, (CDC) Country Offices dedicated to strengthening public health capacity (Martin and Fall 2021) . Abbott and TEPHINET will collaborate by providing funding and mentoring FETP Fellows to support projects in pathogen discovery and other priority public health research in collaboration with the APDC partners in their home country. While it cannot be predicted when or where the next pandemic will arise, or how the next pandemic pathogen will be transmitted, the SARS-CoV-2 pandemic has made it evident that complacency and inaction will result in great loss of human lives and economic disruptions globally. Human-to-human respiratory transmission poses the greatest risk for rapid dissemination of novel pathogens; however, the toll of HIV, viral hepatitis, malaria, and diarrheal illnesses serve as a reminder for the need to not simply focus on respiratory pathogens. We cannot underestimate the ability of emerging pathogens to surprise us and spread through blood, fecal-oral, sexual contact, or other modes, including vector-borne. To maintain readiness for the next pandemic, the APDC will track and monitor SARS-CoV-2 variants, while continuing surveillance for new and variant blood, air and water-borne pathogens, to identify novel pathogens and collaboratively respond to these threats in a timely manner to prevent and /or mitigate the impact of the next pandemic. The APDC offers some unique attributes in global pandemic preparedness. The strengths of the APDC include: the industry -academic-government collaborations established, the emphasis on building laboratory and epidemiologic capacity especially in LMICs, and the ability to rapidly develop and deploy scalable diagnostic tests following the discovery of a new pandemic threat; all will be key to a timely response to the next pandemic. For the APDC to have the greatest impact in pandemic mitigation and control, its efforts should align with other pandemic preparedness networks, forming a "network of networks". Preparedness funding tends to follow a cyclical pattern-flowing after the emergence of a new outbreak, and then drying up after a period of time, usually not more than a few years, until a new threat triggers another wave of funding (United Kingdom G7 2021) . Over the last century, only two pandemic viruses have killed more people than SARS-CoV-2 (estimated 4.5 million as of September 2021)-the 1918 Influenza Pandemic with an estimated 50 million deaths, and HIV with an estimated 32 million deaths (Morens et al. 2020) . The enormous economic and human costs of SARS-CoV2 highlight the need to rethink the paradigm of "feast or famine" funding, and that pandemic preparedness is a shared responsibility where governments work together with civil society, academia, and the private sector. The APDC, as a multi-sector partnership, with capacity in diagnostics, epidemiology and diagnostics development brings some novel strengths to pandemic preparedness efforts.
