International Cooperative Responses to Pandemic Threats: A Critical Analysis Milan Brahmbhatt Senior Fellow World Resources Institute Olga Jonas Economic Adviser World Bank One of us lives in a large block of apartments. At least a couple of times a year, the fire alarm in the building rings in the middle of the night and within minutes the local fire brigade arrives. There has never been a serious fire in the building. Nevertheless, residents do not complain that the absence of a serious fire merits cutting spending on the fire brigade. Yet, as a world we appear to be willing to spend very little on prevention and control of a larger threat to human welfare than fires: infectious disease outbreaks and pandemics. The worldwide probability of death by fire in 2013 was about 3.5 per 100,000 people.1 According to a World Bank estimate, the global probability of death due to a severe global influenza pandemic is about three times as large, one in 10,000.2 Even so, as we discuss in Section 1, the recent Ebola crisis has demonstrated that the world 163 Milan Brahmbhatt is Senior Fellow at the World Resources Institute and a member of the project team for the New Climate Economy Initiative of the Global Commission on the Economy and Climate, where he leads the work of the Country Transitions workstream.

In 2013, the entire influenza budget of the World Health Organization (WHO) was $7.7 million, less than a third of what New York City alone devotes to public health emergencies.3 In this paper, we argue that the world appears to be seriously underinvesting in international cooperation for the prevention and control of pandemics—for reasons that range from outdated models of the pandemic threat to challenges in the provision of global public goods, in tackling catastrophic risks, and in the political economy of public choice. Nevertheless, these challenges can be met. The economic returns on investments to prevent and better control pandemics are extremely large. The last 15 years provide valuable lessons from both successes and setbacks, suggesting four principles for a plan of action to revitalize international cooperative responses to pandemic threats. Section 2 of this piece argues that insufficient attention to pandemic threats may be partly due to an outmoded notion that scientific progress alone will make infectious diseases an increasingly unimportant health problem. The reality, however, is that there is unlikely to be any final victory in the perennial struggle between humans and harmful microbes. The evolutionary process of natural selection makes it inevitable that new microbial threats will continue to emerge, requiring constant vigilance and the maintenance of strong human and animal public health systems as a front line of defense. Section 3 explores the economics of pandemics, arguing that international cooperation to prevent and control pandemics is an investment with very high expected economic returns. Section 4 discusses why the world appears reluctant to seize this high-return investment, only doing so in sporadic and fragmented ways. Among the challenges to international cooperation are incentive problems in supplying global public goods, behavioral inhibitions in grappling with catastrophic risks, and the political economy of public choice. Section 5 briefly traces the fraught history of international efforts to combat infectious disease outbreaks and pandemics—the “Road to Ebola” as it were. So far in the 2000s we have seen successes—a significant strengthening of WHO’s International Health Regulations (IHR) and a major international effort to tackle the pandemic threat from avian influenza starting in 2005—as well as setbacks—a dispiriting loss of momentum at the end of the decade and the Ebola crisis itself. The article concludes by suggesting four principles for a plan of action to revitalize international cooperation for prevention and control of infectious disease outbreaks and pandemics. the brown journal of world affairs BrahmbhattandJonas_LAYOUT.indd 164 5/6/15 11:29 PM International Cooperative Responses to Pandemic Threats 1. EBOLA EXPOSES MAJOR WEAKNESSES IN THE GLOBAL RESPONSE TO INFECTIOUS DISEASE OUTBREAKS Ebola virus disease is a harmful, often fatal illness in humans caused by the Ebola virus, which is transmitted to humans from wild animals and which spreads in the human population through human-to-human transmission.4 The recent Ebola outbreak began in rural Guinea in early December 2013 but remained under the radar for nearly four months. Although Even in February 2015, there was a $1 billion doctors in the area noticed funding gap between donor contributions clusters of deaths with unusual symptoms and sent and the “Needs and Requirements” for the reports to the Ministry Ebola response requested by UN agencies. of Health, the outbreaks remained unexplained. No action was taken to control the contagion, which continued to spread and ultimately reached the capital and neighboring countries. At this early stage, the Ebola crisis exposed one of the major flaws in the current global framework for tackling infectious diseases: the weakness or even absence of public health systems in many developing countries. 165 The NGO Médécins Sans Frontières (MSF) sent samples to France, where the disease was identified as Ebola on 22 March 2014. Although MSF launched an emergency response at this point, followed by warnings that the situation was worsening, there was a further lapse in the response from the rest of the international community. The critical work of isolation, treatment, and contact tracing was left almost entirely to NGOs, necessarily limited in their capacity, until August. Small teams from WHO and the U.S. Centers for Disease Control and Prevention (CDC) helped monitor the emerging crisis, but it was only in early August that significant funding, skilled health professionals, medicines, and other resources started to be mobilized. On 8 August, WHO declared a formal Public Health Emergency of International Concern (PHEIC) under the IHR. International assistance, however, remained ad hoc, fragmented, and unevenly coordinated. It was only in October 2014 that substantial international assistance, including troops, arrived on the ground. In the meantime, thousands had been infected each week, causing treatment centers to overflow. The approach of passing the hat for the disease control program only after the epidemic was underway further slowed and weakened the response. Even in February 2015, there was still a $1 billion funding gap between donor contributions and the “Needs and Requirements” for the Ebola response requested by UN agencies.5 Spring/Summer 2015 t volume xxi, issue ii BrahmbhattandJonas_LAYOUT.indd 165 5/8/15 6:41 PM Milan Brahmbhatt and Olga Jonas Delays between the onset of the epidemic and the implementation of measures to control the disease proved costly. When contagions grow exponentially, the costs of controlling them rise in tandem. The cost of extinguishing a few smoldering sparks is much less than fighting a blazing fire. Whereas the epidemic could have been controlled for less than $200 million in April 2014, according to a UN estimate, by the fall, the estimate of control costs had risen to $4 billion—a rapid 1,900 percent rise in just six months. These are resources that could otherwise have been devoted to valuable development programs that improve living conditions in poor countries.6 The global response to the Ebola crisis brought to light many weaknesses in international cooperative efforts to combat infectious disease outbreaks and pandemics. How did we arrive at this point? 2. THE PERMANENT ARMS RACE BETWEEN HUMANS AND MICROBES 166 Humans have always lived and will probably always live in a permanent arms race with harmful microbes, despite the growth of scientific knowledge and the development of powerful antibiotics and vaccines. The term microbe refers to bacteria, viruses, protozoa, and other microorganisms. Although most microbes either aid or cause no great harm to humans, a limited number are pathogens, meaning they induce infectious disease patterns in their hosts to spread and further their own reproduction. Evolution ensures a constantly shifting balance of power between microbes and humans. Human populations develop immunity to a given pathogen over time; however, genetic mutations and other biological processes generate lethal new pathogens against which humans have little immunity. Pandemics have swept through human populations throughout history, killing millions and often changing the course of political and economic development.7 Since the middle of the nineteenth century, humans have achieved unprecedented advances in their war with pathogens. Three developments have been of particular importance: the spread of public health systems to promote measures such as better sanitation, cleaner water, and stronger disease surveillance and control; the development of vaccines to control the spread of viruses; and the use of antibiotics to combat bacterial pathogens. Over the course of the twentieth century, these advances had an enormous impact in reducing the incidence of infectious diseases, raising hope that a complete victory over infectious diseases was at hand. By the late 1960s, the U.S. Surgeon General considered the time ripe to “close the book on infectious diseases.”8 the brown journal of world affairs BrahmbhattandJonas_LAYOUT.indd 166 5/6/15 11:29 PM International Cooperative Responses to Pandemic Threats Yet, a complete victory over microbes was not to be realized. A warning sign was the influenza pandemic of 1918–19 that caused 50 to 100 million deaths worldwide even with the great scientific advances of the nineteenth and early twentieth centuries. Remarkably, this “forgotten pandemic” seems to have had little impact on thinking about infectious diseases threats over subsequent decades.9 Nevertheless, by the end of the twentieth century there was growing evidence of the microbial threat’s durability and resilience. The resurgent microbial threat is evident on several fronts. One of the most troubling is the emergence of multiple drug resistant (MDR) bacteria as a result of natural selection, including those that cause cholera, gonorrhea, malaria, and tuberculosis (TB). The growing threat is also seen in the emergence of new infectious diseases and virulent new strains of existing diseases at the pace of about one per year. Numerous examples include Lassa Fever in the 1960s, Ebola in the 1970s, the delayed detection and diagnosis of AIDS in the 1980s, and many highly pathogenic bird and animal influenza viruses in the 1990s and 2000s. These viruses have the capacity to mutate into forms capable of easy transmission among humans, potentially causing a devastating influenza pandemic. 10 Other recently emerged viruses with pandemic potential include Severe Acute Respiratory Syndrome (SARS) in 2003 and the Middle East Respiratory Syndrome (MERS) in 2012. Importantly, around 75 percent of these newly emerging pathogens are of animal origin: so-called zoonoses, or infectious diseases found in animals that can be transmitted to humans under natural conditions.11 The emergence of zoonoses appears to have accelerated as the push of human settlement into tropical regions brought people into contact with previously isolated animalborne pathogens, such as AIDS and Ebola. Zoonoses have also grown in importance as the stock of domesticated animals has grown with global economic development, thereby creating more opportunities for animal pathogens to be transmitted to humans. The denser and more rapid global transport networks of recent times further hasten the international spread of infectious diseases. Basic veterinary and human public health systems—the first line of defense against infectious diseases—remain weak in many developing countries, and have even collapsed entirely in some failed states. Eight out of 10 countries do not comply with WHO’s IHR because they lack the capacity to perform the core veterinary and human public health functions of detecting, diagnosing, and controlling contagions.12 The resilient, multifaceted, and permanent nature of the microbial threat has important implications for public health policies. Instead of viewing each 167 Spring/Summer 2015 t volume xxi, issue ii BrahmbhattandJonas_LAYOUT.indd 167 5/8/15 6:41 PM Milan Brahmbhatt and Olga Jonas emerging infectious disease as a separate threat that requires its own frantic emergency response, we argue below that it would make significantly more sense to build a common core of permanent capabilities at both the national and global levels that can be applied against a wide range of microbial threats. 3. THE ECONOMICS OF INFECTIOUS DISEASE AND PANDEMICS Given that infectious diseases are a permanent threat to human health, what level of the world’s scarce resources should we allocate to preventing and controlling infectious disease outbreaks and pandemics? The answer depends on the economic costs of these diseases. These costs in turn depend to a large extent on the specific epidemiological characteristics of a given disease, as well as on its broader social context and on the effectiveness of various public health measures to control outbreaks. The economic costs of pandemics are of two kinds. First are the direct and indirect costs of illness. The direct costs of illness are the resources used to treat or cope with the disease, including costs of hospitalization and medication. Indirect costs of illness comprise the present and future costs to society from morbidity, disability, and premature death, in particular the loss of output caused by the 168 reduced productivity or death of workers. Second are the costs of contagion avoidance. These include the economic disruptions that often result when the public acts spontaneously to avoid becoming infected—for example, by avoiding crowded areas, travel, or workplaces. These actions can cause serious disruptions to supply and demand in key The costs of contagion avoidance can sectors such as tourism, retail trade, transport, and entersometimes comprise the bulk of the tainment. Avoidance costs costs of an infectious disease outbreak. also include those incurred by social-distancing measures enforced by governments—that is, public health measures such as the temporary shutdown of nonessential government activities, school and market closures, quarantines, travel suspensions, and trade embargoes. The costs of contagion avoidance can sometimes comprise the bulk of the costs of an infectious disease outbreak. The 2003 SARS outbreak, for example, was estimated to have caused GDP losses of 0.5 to 1 percent in China, Taiwan, Hong Kong, and Singapore, the most affected economies. These losses were far too large to be explained by the costs of illness and death associated with the 8,096 cases of infection and 776 deaths caused by SARS. Instead, they primarily the brown journal of world affairs BrahmbhattandJonas_LAYOUT.indd 168 5/6/15 11:30 PM International Cooperative Responses to Pandemic Threats reflected the widely reported economic disruptions caused by the spontaneous avoidance actions of the public.13 One World Bank study estimated the cost of a severe influenza pandemic, modeled on infection and mortality patterns of the 1918 flu pandemic, at 4.8 percent of world output.14 Given the gross world output of $87 trillion in 2013 in purchasing power parity terms, this would represent a GDP loss of some $4.2 trillion.15 There have been four influenza pandemics over the past century: the 1918–19 pandemic mentioned above and three less serious pandemics in 1958, 1968, and 2009. We assume for illustrative purposes that a serious infectious disease pandemic occurs on average once in a hundred years (i.e. a 1 percent probability of occurring in any given year) with an economic impact similar to the World Bank estimate for a serious flu pandemic.16 Then the annualized expected cost of a serious pandemic—or equivalently, the benefit from averting such a pandemic—is $42 billion per year. This is about 12 times the annual investment of $3.4 billion needed to strengthen veterinary and human public health systems in developing countries to the standards defined by the World Organization for Animal Health (OIE) and WHO, according to World Bank estimates.17 Such an investment would be worth undertaking even if serious pandemics occur only once every 200 years and if the investment succeeded in preventing only one out of five pandemics. Current investment rates in these systems are far below desired levels, only about $350 million per year. Lawrence Summers, former U.S. Treasury secretary and chair of the Lancet Commission on Investing in Health, recently highlighted the risk of a serious flu pandemic, noting that “Optimists think that the risk is 1 percent a year. Pessimists think that the risk is 2 percent a year. Pandemic flu, if it came today, would likely be worse than [it was in] 1918 because of the greater communicability around the world.” Given the odds and the costs of a serious pandemic, Summers described investing in pandemic preparedness as “probably the single most important area for productive investment on behalf of mankind.”18 Figure 1 (on the next page) provides a stylized view of how the costs of controlling a zoonotic outbreak escalate over its various stages. Arresting the exponential growth in costs early—by means of investment in veterinary and human public health systems—is evidently a more economically sound decision than delaying a response.19 169 Spring/Summer 2015 t volume xxi, issue ii BrahmbhattandJonas_LAYOUT.indd 169 5/8/15 6:41 PM Milan Brahmbhatt and Olga Jonas 170 4. CHALLENGES THREATS FOR INTERNATIONAL COOPERATIVE RESPONSES TO PANDEMIC While prevention and control of infectious disease outbreaks and pandemics represents an investment with very high returns for global well-being, there are also significant challenges that need to be tackled to achieve this desirable outcome. Pandemic prevention and control is a global public good because it is nonexcludable—prevention and control efforts by one country benefit not only that country, but also all others—and nonrival—enjoyment of the benefits of pandemic prevention and control by one country does not reduce the benefit available to other countries.20 Like any public good, pandemic prevention faces the so-called free-rider problem: there exists the temptation to enjoy its benefits while letting other countries pay for it. These problems can however be overcome when international cooperative efforts are designed in ways that provide adequate incentives for countries to participate. We review both successes and setbacks in international health cooperation in the next section. Another challenge is that pandemics belong to the class of catastrophic risks. These are risks that have a small and uncertain probability of occurring, the brown journal of world affairs BrahmbhattandJonas_LAYOUT.indd 170 5/6/15 11:32 PM International Cooperative Responses to Pandemic Threats but hold potentially disastrous outcomes. There is significant evidence that humans, including policymakers, have a hard time rationally prioritizing actions when dealing with these kinds of problems, resulting in too little long-term investment in the prevention of catastrophic risks.21 Instead, one sees a typical pattern in which infectious disease outbreaks lead to brief spurts in funding for emergency responses to the immediate problem—but this funding rapidly tails off rather than providing what is truly needed, a stable, long-term stream of resources to build a permanent capacity for infectious disease prevention and control, particularly in developing countries.22 Such an approach would not only be more effective in controlling outbreaks promptly—it would also be less expensive than the current approach in helping avoid the dramatic escalation of costs that typically occurs when an outbreak has spiraled out of control. As previously noted, policymakers may also be influenced by outmoded mid-twentieth-century notions of different infectious diseases as distinct problems divorced from a consistent pattern; these diseases are also seen as becoming less important due to scientific progress. A more accurate perspective would view these outbreaks as manifestations of a broad class of permanent and serious microbial threats to human health. Lastly, there is the unfortunate reality that policies are generally chosen not on the basis of purely rational cost-benefit analysis, but more frequently on the basis of private and public interest group pressures, lobbying, and other political processes that may favor ad hoc, shortterm responses rather than stable, long-term solutions. Politicians and civil servants may, for example, find enticing opportunities for advancement in a highly visible emergency response to an outbreak. Successful but less visible prevention of outbreaks might not bring such rewards. 5. PATTERNS OF INTERNATIONAL POLICY RESPONSES OUTBREAKS AND PANDEMICS TO 171 INFECTIOUS DISEASE Countries have grappled with the problem of how to build international cooperative action against infectious disease outbreaks and pandemics for more than 150 years. The last 15 years in particular have shown a combination of both promising advances and disheartening setbacks in this cooperative effort—both of which yield valuable lessons for the future. Important milestones in international health cooperation included a series of International Sanitary Conferences between 1851 and 1938 and the founding of OIE in 1924 and WHO in 1948 as the primary international organizations for animal and human health respectively. WHO’s International Sanitary Regula- Spring/Summer 2015 t volume xxi, issue ii BrahmbhattandJonas_LAYOUT.indd 171 5/8/15 6:41 PM Milan Brahmbhatt and Olga Jonas tions in 1951 provided a single set of rules for responding to six specific infectious diseases. Importantly—unlike earlier treaties that required countries to opt in to the agreement—the Regulations adopted an opt-out rule that automatically binds all WHO members. This important institutional innovation helps to offset the free-rider problem, discussed in the previous section, by creating moral and behavioral pressures in favor of cooperation between countries.23 The SARS outbreak in 2003 appears to have played an important role in reawakening global awareness of the pandemic threat.24 It was followed by considerable strengthening of the IHR in 2005. There was also a major international cooperative response to the threat of a human influenza pandemic that arose from H5N1 avian flu, beginning in 2005. Yet, by the end of the decade this positive momentum had weakened, accompanied by a loss of focus that set the stage for the problematic Ebola response. The revised IHR expanded coverage from six specific diseases to any “public health emergency of international concern.”25 They also provided an innovative set of guidelines to help countries decide when to notify WHO of a public health event, formalized information links between WHO and member countries, and allowed WHO to take account of a wide range of information from NGOs, the media, and other sources. Perhaps most importantly, the IHR 172 required member countries to undertake a formal evaluation of their public health capacities by 2009 and to develop an operational plan to bring these capacities up to required standards. The public health capacities designated for evaluation included surveillance, reporting, notification, verification, response, and collaboration.26 Valuable as they were, the revised IHR had several flaws. First, there was no formal provision for aid to help weaker developing countries upgrade their public health systems to the specified levels. The amount of aid was left to the discretion of individual donors and has generally been well below the levels needed to fulfill the new IHR’s mandate. The mission of WHO has become The 2009 U.S. Global Health extraordinarily diffuse. The IHR are now Initiative, for example, did not mention implementation of but one of a great number of objectives. the IHR as a target for U.S. assistance.27 Second, and perhaps just as important, there was no provision for the enforcement of obligations undertaken by countries. Third, as critics have observed, the mission of WHO has become extraordinarily diffuse. The IHR are now but one of a great number of objectives that include universal health coverage, noncommunicable diseases, the brown journal of world affairs BrahmbhattandJonas_LAYOUT.indd 172 5/6/15 11:33 PM International Cooperative Responses to Pandemic Threats the Millennium Development Goals, and addressing the social, economic, and environmental determinants of health as a means of reducing health inequities, among others. Funding for work to mitigate infectious disease threats in WHO’s budget has been cut. The result has been a loss of focus on and prioritization of infectious diseases and global health security.28 Viewed analytically, international collective action on health should provide two different types of functionality: core functions and supportive functions. Core functions comprise the provision of global public goods related to health, which individual countries cannot provide for themselves. Compliance with the IHR is the quintessential example of a core function. In contrast, supportive functions are not global public goods and should, in principle, be undertaken by national governments. However, some poorer developing country governments may be unable to build such functions by themselves, and thus they are then supported internationally for humanitarian or altruistic reasons. An example of a supportive function would be aid for anti-smoking programs in developing countries. The bulk of development aid for health is for supportive functions.29 It has been persuasively argued that these two functions could be better achieved with a cleaner division of labor, with WHO focusing wholly on core global public good functions such as the IHR, while other development partners—such as development banks, aid agencies, charitable foundations, and NGOs—take the lead on supportive functions. These partners would also help ensure that WHO and OIE are adequately funded to deliver on core global public good mission.30 As noted at the start of this section, another key development after 2005 was a major international collaborative effort to tackle the pandemic threat from H5N1 avian influenza: the Global Program for Avian Influenza Control and Human Pandemic Preparedness and Control (GPAI). Political leadership by the United States and the European Union helped mobilize $4 billion for this effort from more than 30 donor countries, combined with effective cooperation between the UN, WHO, the World Bank, the Food and Agriculture Organization of the UN, and OIE. Most of the funding went to strengthening veterinary and human public health systems in developing countries, with the purpose of better preventing and controlling infectious diseases in general, rather than the avian flu alone. Five ministerial conferences between 2006 and 2010 raised funds, bolstered international political commitment, and enabled the exchange of experiences among countries. Technical assessments of the quality of animal and human public health systems were undertaken in many developing countries, including in Guinea, Liberia, and Sierra Leone, the three countries 173 Spring/Summer 2015 t volume xxi, issue ii BrahmbhattandJonas_LAYOUT.indd 173 5/8/15 6:41 PM Milan Brahmbhatt and Olga Jonas that would later be most affected by the Ebola crisis. These assessments were followed by the drafting of Integrated National Action Plans for investments to bring public health systems up to minimum standards. There was growing appreciation of the need for “One Health” approaches that closely coordinate human and animal public health systems.31 Unfortunately, these Action Plans were by and large never funded or implemented. As many developing countries came to grips with the immediate problem of controlling avian flu, funding from donors rapidly tailed off after 2008. This trend occurred even as the H5N1 flu virus continued to circulate and other new and dangerous flu viruses, as well as other pathogens, continued to emerge. With reduced public attention and so-called “pandemic fatigue” in 174 the brown journal of world affairs BrahmbhattandJonas_LAYOUT.indd 174 5/6/15 11:33 PM International Cooperative Responses to Pandemic Threats the media, the political incentives for policymakers to continue working on pandemic threats quickly dissipated (Figure 2).32 From 2008 on, the global financial crisis effectively monopolized the attention of top policymakers in any case. It was at this time that the 2009 H1N1 flu pandemic provided the first test of the revised IHR. By all accounts, the system worked as intended. Early warnings by affected countries such as Mexico enabled WHO to promptly announce a Public Health Emergency of International Concern and allowed other countries to launch their own responses. Coordinated action between Mexico, the United States, and Canada in particular allowed for early control of the virus. Yet, in the climate of pandemic fatigue, even this generally successful response led to a backlash against WHO, with unfounded criticisms that it had declared a “fake” pandemic.33 This backlash is likely to have further discouraged international organizations and donors from supporting work on pandemic preparedness and public health systems.34 CONCLUSION: WHERE DO WE GO FROM HERE? As the world slowly emerges from the long aftermath of the global financial crisis, it is time for leaders to once more take on the pandemic threat, drawing on both the positive and negative lessons of the last 15 years. A plan of action based on the following four principles can significantly enhance global health and economic security for this and future generations. First, there needs to be a clear understanding that infectious disease outbreaks are not one-off events that are best tackled only after they occur, with hurriedly improvised emergency efforts. Rather, infectious disease outbreaks are a permanent feature of the world that warrant a robust and systematic defense. New or more resistant strains of infectious diseases will continue to emerge as natural selection does its work and as pathogens mutate and evolve. We therefore need permanent institutions, instruments, and policies backed by stable and sustained funding to tackle infectious disease and pandemic threats in a unified way. The economic rationale for such a strong and permanent effort is clear. The costs of infectious disease outbreaks and pandemics are extremely high, as are the economic returns on investments to prevent and control such events. Second, there needs to be a clear-eyed appreciation of the challenges facing international cooperation over containing pandemic threats, including classic incentive problems in supplying global public goods, low pandemic threat awareness, behavioral difficulties in tackling catastrophic risks, and the political economy of public choice. To tackle these problems, it will be helpful to make 175 Spring/Summer 2015 t volume xxi, issue ii BrahmbhattandJonas_LAYOUT.indd 175 5/8/15 6:41 PM Milan Brahmbhatt and Olga Jonas 176 a clear policy distinction between the core and supportive functions of international health cooperation. The core function is to supply global public goods, the most important of which are global health security and implementation of the IHR. The supportive function is to help developing countries pursue health goals that primarily benefit the residents of these countries themselves. While both functions need adequate and stable support, there is a strong case for a clear organizational division of labor, with international health bodies such as WHO narrowing and intensifying their focus on leadership in order to deliver core functions. Partners such as development banks, aid agencies, charitable foundations, and NGOs can aid WHO in its core mission, while also taking the lead in the provision of supporting functions. Third, given the zoonotic nature of most emerging infectious disease threats, a “One Health” approach that builds cooperation and coordination between animal and human public health systems is essential. Robust veterinary systems that meet OIE standards are needed to provide early warning, curb antibiotic and other drug resistance in microbes, and control emerging animal diseases in a cost-effective manner before they threaten humans. Fourth, as the Ebola crisis vividly demonstrated, public health systems in developing countries are the weakest link in global cooperation against pandemic threats. According to the World Bank, “investments in public health are a notorious blind spot in health systems financing: interventions are often invisible to consumers of health care and, as such, fall to the bottom of the priority list.”35 A sustained investment to significantly strengthen veterinary and human public health systems in developing countries by 2030 should be at the top of the international health and development cooperation agenda. Such an effort will allow a much greater reduction in threats to global health and economic well-being than is possible with current capacities and will yield extraordinarily high returns for both developing and developed countries.

We do know enough about the long-run historical frequency of influenza pandemics in the past to form a strictly empirical estimate of their probability in future. However, for the purpose of estimating the expected costs of infectious disease pandemics, the annual 1 percent probability we have assumed is likely to be a conservative estimate, since it ignores the impact of more moderate influenza pandemics (of which there were three in the past century), as well as the impact of pandemics caused by infectious diseases other than influenza. As discussed later in the text, Larry Summers, Chair of the Lancet Commission on Investing in Health, reports a 1 percent probability to be relatively optimistic. 17.
