The dissonance between the public health services provided in developed countries compared with those promoted by donors in developing countries is curious and costly. Population-wide services are a core component of publicly funded health services in developed countries, and are underpinned by a framework of public health regulations to reduce exposure to communicable diseases.1Barnett DB Beck JE Johnson W Konkel S Environmental health in public health.in: Scutchfield FD Keck CW Principles of public health practice. Delmar Learning, New York2002: 431-442Google Scholar In developing countries, donors and international aid agencies have prioritised clinical services above population-wide services. Population-wide health services are largely non-clinical and seek to reduce disease through implementation of health regulations, surveillance, assessment of health threats, and control of outbreaks. Such services constitute a public good in the sense that they protect the whole population, and complement clinical services for prevention and treatment of disease. Developed countries periodically upgrade their public health systems—eg, the EU formed the European Centre for Disease Prevention and Control—and over time, citizens' expectations have risen such that providing poor public goods in health is politically unacceptable. Low-income countries need to prioritise services that produce public goods to more effectively improve health outcomes for their people, especially in view of their limited resources and high burdens of communicable disease. International health security cannot be ensured without strong national population-wide health services to reduce the spread of diseases across borders. Donors have neglected population-wide services in their efforts to strengthen health systems. They have focused on expansion of access to health-care services, and on programmes to address specific diseases and maternal and child health.2Stern AM Markel H International efforts to control infectious diseases, 1851 to the present.JAMA. 2004; 292: 1474-1479Crossref PubMed Scopus (54) Google Scholar, 3Howard-Jones N The World Health Organization in historical perspective.Perspect Biol Med. 1981; 24: 467-482PubMed Google Scholar Donors' efforts to strengthen population-wide services have been piecemeal—eg, some improvement of disease surveillance or outbreak control. A strong population-wide system is crucial both to respond to disease outbreaks and to address potential health threats before an outbreak can occur. A striking manifestation of this neglect is a scarcity of coherent public health regulations in many countries with which donors have been working for decades.4Gupta M Das Rani M India's public health system—how well does it function at the national level?

World Health Organization, Geneva2007Google Scholar with the increasing evidence of re-emerging diseases for which present treatments are inadequate. However, donors and international aid agencies must first clarify the constituents of an effective public health system and the process for helping countries to build them. Neglect of services that reduce exposure to disease is associated with very high costs, and therefore the real issue is not whether developing countries can afford to have population-wide health services, but whether they can afford not to have them. The World Bank estimates that the cost of poor sanitation is more than 1% of gross domestic product (GDP) in Colombia and 1·4% in Bangladesh.6World BankEnvironment story.

Our continuing study in Sri Lanka (unpublished), in collaboration with the Sri Lankan Institute for Health Policy, has shown that a wide range of population-wide services can be provided with simple low-cost approaches. Combined with maternal and child health service outreach, these services cost less than 0·2% of GDP. Heavy expenditure on sanitary infrastructure, such as sewerage, is not necessary since most of the population uses stand-alone latrines. With good public provision of sanitary and clinical services, Sri Lanka has high levels of health equity11Rannan-Eliya RP Sikurajapathy L Sri Lanka: "good practice" in expanding health care coverage.in: Gottret P Schieber G Waters HW Good practices in health financing: lessons from reforms in low and middle-income countries.

The neglect of population-wide health services by donors and international aid agencies, which has contributed to weakened public health systems, is evident both intellectually and programmatically. Donors and international aid agencies have little understanding of population-wide services, to the extent that their employees who focus on public health services specify that these services are not synonymous with publicly funded health services.12WHOEverybody's business: strengthening health systems to improve health outcomes: WHO's framework for action.

The Alma-Ata declaration of 1978 emphasised that a comprehensive approach to primary health care should include safe water and sanitation, and prevention and control of endemic diseases. In 2000, however, WHO pointed out that the goals remained largely unmet because of various shortfalls, such as absence of clarity about targets and how to meet them, compounded by shortages of funding and training.14WHOWorld Health Report 2000—health systems: improving performance. World Health Organization, Geneva2000Google Scholar The intellectual shift away from population-wide health services has become so extreme that interventions to improve environmental sanitation have become classified as outside the health sector. Sanitation was even excluded from the original Millennium Development Goals, implying that it was unnecessary to meet child survival goals despite the high proportion of child deaths resulting from poor sanitation.7Prüss-Üstün A Bos R Gore F Bartram J Safer water, better health. World Health Organization, Geneva2008Google Scholar By this logic, the health sector's responsibility for management of diarrhoeal diseases is confined to treatment and improvement of personal health behaviour, but not reduction of exposure to faecally-transmitted diseases. By contrast, in developed countries, a principal function of public health agencies is to monitor the quality of sanitation services and to pressure providers to improve them. Donor initiatives related to environmental sanitation—eg, the Water and Sanitation Program—concentrate on expanding the coverage of adequate water and sanitation facilities, with sanitation narrowly defined in terms of latrines. These initiatives are receiving increasing attention in the donor community,6World BankEnvironment story. Water and poverty: what's the connection?.http://youthink.worldbank.com/4teachers/pdf/environment/story-waterandpoverty.pdfGoogle Scholar but to be more effective, efforts should also focus on the institutional mechanisms needed to monitor the subsequent operation of these services to keep health threats to a minimum. Environmental management of vector-borne diseases has also been addressed in the developed world through multisectoral coordination, initially to eradicate these diseases and now to ensure that they do not re-emerge. The Tennessee Valley Authority, which eradicated malaria and other mosquito-borne diseases from a large tract of the USA in the 1930s, continues to collaborate with the health department to monitor mosquito breeding.16Lindsay S Kirby M Baris E Bos R Health, nutrition and population discussion paper.

World Bank, Washington, DC2004Google Scholar These crucial services can be provided in developing countries by strengthening population-wide health systems. Programmatic interventions by donors and international aid agencies tend to rely heavily on the use of modern medical technology, rather than strengthening systems to deliver population-wide health services. This approach has been applied successfully—notably, to target vaccine-preventable diseases—but in the case of malaria, reliance on DDT (dichloro-diphenyl-trichloroethane), bednets, and early treatment has proved inadequate since effective control also needs complex management of the disease environment.6World BankEnvironment story.

Environmental management for malaria control in the East Asia and Pacific (EAP) region. World Bank, Washington, DC2004Google Scholar Single-focus programmes can be used to strengthen specific parts of a health system, but they can also unravel health systems and expertise, so these programmes should be balanced with building and maintaining the overall capacity of preventive health systems. Reliance on DDT, for example, failed to eradicate malaria, but ironically has "almost eradicated public health scientists with an interest in environmental management".16Lindsay S Kirby M Baris E Bos R Health, nutrition and population discussion paper.

World Bank, Washington, DC2004Google Scholar Concentration of resources into single-focus programmes increases pressure on existing population-wide health systems. For example, since the mid-1950s, health workers in India have been asked to focus on the priority programmes of the day, to the detriment of other important but routine services.17Gupta M Das Public health in India: an overview. World Bank, Washington, DC2005: WPS3787Google Scholar Similarly, districts in Tanzania have prioritised the diseases covered by donor-supported programmes, and neglected other diseases such as filariasis and schistosomiasis, which health workers and communities regarded as serious problems.18Mubyazi G Kamugisha M Mushi A Blas E Implications of decentralization for the control of tropical diseases in Tanzania: a case study of four districts.Int J Health Plann Manage. 2004; 19: S167-S185Crossref PubMed Scopus (30) Google Scholar International aid agencies can also further compound dysfunctionalities in health systems by setting up alternative delivery mechanisms for their programmes.19Travis P Bennett S Haines A et al.Overcoming health-systems constraints to achieve the Millennium Development Goals.Lancet. 2004; 364: 900-906Summary Full Text Full Text PDF PubMed Scopus (605) Google Scholar The Pan American Health Organization (PAHO) has offered useful lessons about how international aid agencies can develop long-term partnerships with member countries to strengthen their health systems.20Cueto M The value of health: a history of the Pan American Health Organization. Pan American Health Organization, Washington, DC2007Google Scholar In 1924, member countries first signed the Pan American Sanitary Code, which established a legal requirement to notify other countries of disease outbreaks, similar to WHO's revised International Health Regulations. But the code has also gone much further by establishing a legal framework to lay the basis for technical collaboration between the Pan American Sanitary Bureau and its member countries to reduce disease burdens within each country. This collaboration seeks to systematically strengthen all aspects of health systems, including population-wide services. For example, PAHO's programme with Belize includes training of environmental health officers and strengthening of water quality monitoring, solid waste management, vector control, and food safety.21PAHOBelize Country Office.

Pan American Health Organization, Washington, DC2002Google Scholar Worldwide threats from bioterrorism, and emerging and drug-resistant diseases, have led to revived interest in building and maintaining strong public health systems. Developed countries have strengthened their public health systems, and increasingly understand that their health security will benefit from improvement of other countries' capacities to control their communicable diseases. International aid agencies have also begun to focus on health systems—eg, WHO's revised International Health Regulations address public health emergencies of international concern and health system capacities. Unfortunately, WHO mainly focuses on the capacity of health systems to detect and respond to disease outbreaks of international concern, which is inherently inefficient. If health systems are poorly prepared to implement health regulations and other measures to reduce exposure to disease, there will be repeated outbreaks to control. Subsequently, WHO has stated its intention to better strengthen health systems beyond outbreak surveillance and response, to include systems to predict and prevent exposure to health hazards.12WHOEverybody's business: strengthening health systems to improve health outcomes: WHO's framework for action. World Health Organization, Geneva2007: 2Google Scholar However, key gaps remain. In the framework for action document, the role of a regulatory framework is buried with many other priorities in the subsection on governance, and does not mention public health regulations with the regulatory issues to be addressed. Developed countries are increasingly aware of their inability to remain insulated from the external effects of poor health systems in developing countries, offering the opportunity to focus international cooperation on strengthening population-wide health systems. However, effective global health security needs all countries to have the capacity to anticipate, avert, and control all major threats from existing and emerging communicable diseases. WHO's present strategy to detect and control outbreaks of diseases judged to be of international concern is insufficient. Concerted attention and resources for capacity building offer new opportunities for international collaboration to create public goods in health. To this end, we offer a few suggestions. First, information about the basic institutional and regulatory underpinnings of population-wide services should be compiled to help countries and donors improve these services. Analysis of the approaches used in countries such as Sri Lanka can show the strengths and weaknesses of different system designs. Second, international collaboration needs to be channelled towards building and maintenance of national health systems, with a focus on long-term collaboration to build public goods in health.19Travis P Bennett S Haines A et al.Overcoming health-systems constraints to achieve the Millennium Development Goals.Lancet. 2004; 364: 900-906Summary Full Text Full Text PDF PubMed Scopus (605) Google Scholar This effort should draw lessons from PAHO's successful collaboration with its member countries despite their political and economic exigencies. Third, global health cooperation needs a good framework for action, such as Gostin24Gostin LO Meeting basic survival needs of the world's least healthy people toward a framework convention on global health.Georgetown Law J. 2008; 96: 331-392Google Scholar has proposed. This framework would help coordinate the fragmented activities of international organisations, countries, non-governmental organisations, and civil society, and create incentives for more effective international health assistance. Donors and international aid agencies need to radically change their approach to working with developing countries, with the new goal of strengthening their population-wide health systems. This goal is crucial for enhancement of the effectiveness of existing initiatives to improve health systems, water and sanitation, and health security.
