Abstract

The 2005 International Health Regulations (IHR) came into force for all Member States of the World Health Organization (WHO) in June 2007 and the deadline for achieving compliance was June 2012. The purpose of the IHR is to prevent, protect against, control – and provide a public health response to – international spread of disease. The territory of the United Kingdom of Great Britain and Northern Ireland and that of several other Member States, such as China, Denmark, France, the Netherlands and the United States of America, include overseas territories, which cover a total population of approximately 15 million people. Member States have a responsibility to ensure that all parts of their territory comply with the IHR. Since WHO has not provided specific guidance on compliance in the special circumstances of the overseas territories of Member States, compliance by these territories is an issue for self-assessment by Member States themselves. To date, no reports have been published on the assessment of IHR compliance in countries with overseas territories. We describe a gap analysis done in the United Kingdom to assess IHR compliance of its overseas territories. The findings and conclusions are broadly applicable to other countries with overseas territories which may have yet to assess their compliance with the IHR. Such assessments are needed to ensure compliance across all parts of a Member States’ territory and to increase global health security.

Introduction

The 2005 International Health Regulations [IHR (2005)] came into force in June 2007 for 194 countries, including all Member States of the World Health Organization (WHO).1 The deadline for compliance was June 2012. Nine Member States, including China, Denmark, France, the Netherlands, the United Kingdom of Great Britain and Northern Ireland and the United States of America, have overseas territories with a total population of more than 15 million people (Table 1).2,3 These territories fall under the jurisdiction and sovereignty of the mainland yet are often self-governing and have their own legal and public health systems. However, each Member State has a responsibility to ensure that all parts of its territory comply with the IHR (2005).

The epidemiology of disease in overseas territories has been reported to differ from that in their respective mainland territories.4,5 For example, epidemics of tropical diseases that are largely absent from mainland Europe persist in the Caribbean overseas territories of some European nations.5 Some overseas territories receive a large number of holidaymakers from their respective mainlands, which increases the risk of disease being imported in both directions. It is therefore of paramount importance that all Member States with overseas territories are aware of the situation regarding full compliance with the IHR (2005).

The purpose of the IHR (2005) is “to prevent, protect against, control – and provide a public health response to – the international spread of disease in ways that are commensurate with and restricted to public health risks and which avoid unnecessary interference with international traffic and trade.”1 Under the revised regulations, Member States have much broader obligations to build national capacity for surveillance and response in the event of a public health emergency of international concern and to share information about such emergencies. The regulations include a code of conduct for notification and response.

The IHR (2005) requires countries to assess the ability of existing national structures, capacities and resources to meet minimum requirements for public health surveillance and response. These assessments, together with the consequent development of plans to ensure compliance with the IHR (2005), were supposed to be completed by June 2012. However, fewer than 20% of Member States met this deadline.6

No specific guidance on compliance with the IHR (2005) has been provided by WHO for the special circumstances of Member States with overseas territories, which indicates that compliance by overseas territories should be assessed by Member States themselves. To our knowledge, no reports have been published to date on the assessment of IHR compliance in countries with overseas territories.

The aims of this paper were: (i) to provide an overview of a gap analysis done to assess IHR compliance of the United Kingdom’s overseas territories and to identify appropriate measures that could be taken to ensure compliance by June 2014; and (ii) to discuss the policy implications of the findings of the gap analysis, which may be relevant to other countries with overseas territories.

Compliance by overseas territories

Although mainland United Kingdom was almost fully compliant with the IHR by June 2012, it was recognized that compliance by the United Kingdom’s overseas territories and crown dependencies required further assessment. An extension of the deadline for IHR compliance to June 2014 was therefore obtained.

The United Kingdom has 16 overseas territories and three crown dependencies (Fig. 1). These territories and dependencies are heterogeneous in terms of: (i) geography and environmental conditions (one crown dependency is located less than 70 miles from mainland United Kingdom, whereas others are some of the most remote islands in the world); (ii) population size, which ranges from zero in uninhabited territories to 95 000; and (iii) income (the per capita gross domestic product ranges from less than one tenth to nearly double that of the United Kingdom).3 These factors all influence the public health situation in the territories and dependencies.4,7 Between the introduction of the IHR (2005) in June 2007 and the end of December 2010, only one public health emergency of international concern was declared by WHO: pandemic influenza A (H1N1) in 2009. However, other events occurred in the United Kingdom’s overseas territories and crown dependencies that fell within the remit of the IHR (2005), including a measles outbreak in Saint Helena in 2010 and an outbreak of respiratory illness in Tristan da Cunha in 2007.8

Assessing compliance

A structured, self-assessment questionnaire on compliance with the IHR (2005) was designed for the United Kingdom’s overseas territories and crown dependencies following a literature search on the implementation of, and assessment of compliance with, the regulations in other countries. The format of the questionnaire was based on a self-assessment tool proposed by WHO.911 However, since the level of detail in this tool exceeded the requirements laid out in the IHR, the questionnaire was used for collecting information but did not serve as the standard for assessing compliance.

For 15 of the United Kingdom’s 19 overseas territories and crown dependencies, structured telephone interviews were carried out with individuals named on the United Kingdom’s national focal point distribution list. These individuals were often directors of public health or chief medical officers but colleagues they deemed necessary to answer the questions posed, such as epidemiologists, emergency planning officers and food safety experts, were also interviewed. Interviewees were encouraged to complete the self-assessment questionnaire before the interview. In the four remaining territories, no telephone interviews were carried out but further discussions were conducted by email, when necessary, after the self-assessment questionnaires had been completed.

In our assessment, compliance with IHR (2005) core capacity areas was assessed using descriptions of these areas in the IHR (2005) themselves rather than the higher level of detail included in the self-assessment tool provided by WHO. This approach is consistent with that adopted for mainland United Kingdom. Compliance was assessed using a traffic light system: (i) red for areas in which the overseas territory or crown dependency was not compliant; (ii) amber for areas in which there was broad compliance but which would benefit from further work to strengthen some components of the core capacity area; and (iii) green for areas in which there was full compliance.

We found that all territories and dependencies were largely compliant in the IHR (2005) core capacity areas (Fig. 2). For three territories – British Antarctic Territory, British Indian Ocean Territory and South Georgia and the South Sandwich Islands – questionnaire responses indicated that the majority of the core capacity areas did not apply because the territories do not have indigenous populations. However, each had a national focal point for communications and a contact for coordinating activities associated with the IHR (2005). Five other overseas territories and crown dependencies were broadly compliant in all core capacity areas, where applicable, but would benefit from development work to strengthen public health systems.

Implications for countries

Our assessment of the compliance of the United Kingdom’s overseas territories and crown dependencies with the IHR (2005) identified common areas where further work had to be undertaken to ensure compliance and where the ability of these territories and dependencies to detect and respond to a public health emergency could be improved. These findings will be applicable to other countries with overseas territories.

First, the majority of the United Kingdom’s overseas territories and crown dependencies needed to update emergency response plans to comply with Annex 1A [item 6(g)] of the IHR (2005).1 This is also likely to be the case for other overseas territories. Any update to existing plans must: (i) incorporate an all-hazards approach (i.e. be able to deal with zoonosis, food safety and chemical and radionuclear events); (ii) identify supply lines for stockpiles of priority drugs, protective equipment for personnel, chemical antidotes to toxins and emergency supplies to deal with a radiation hazard; and (iii) identify resources outside the territory that can boost surge capacity (i.e. the ability to deal with a surge in cases) in the event of a public health emergency – this may involve the creation of appropriate memoranda of understanding with other parties to define both the relationship and expectations.

Although all of the United Kingdom’s overseas territories and crown dependencies had the technical ability to respond to a public health emergency or public health emergency of international concern, the majority did not have the necessary expertise in zoonosis, food safety or dealing with chemical or radionuclear events because of their population size and geographical isolation. This is likely to be the case for all overseas territories, particularly as it has been observed that, in much of the world, the surveillance capacity for public health incidents involving chemical or radionuclear material is underdeveloped or nonexistent.12 To achieve compliance, all overseas territories should compile a directory of expertise, which includes memoranda of understanding with appropriate external organizations, to bridge the gap in expertise and surge capacity – collaboration is a key aspect of the IHR (2005).13 In addition, an inventory of potential hazards should be compiled and training on all hazards should be given.

The ability to assess points of entry is regarded as critical by WHO and it has been noted that meeting IHR (2005) obligations with regard to points of entry is a universal challenge.14 For many overseas territories it may not be appropriate to designate a point of entry for IHR purposes as many ports and airports in these territories are unlikely to have the facilities or resources to deal with a public health emergency of international concern. The United Kingdom’s overseas territories were therefore recommended not to designate points of entry for IHR purposes. A number of UK overseas territory ports do have the capacity to issue ship sanitation certificates and a list of these ports has been provided to WHO in accordance with article 20 (item 3) of the IHR (2005).1 Furthermore it may be technically challenging to ensure that all core capacity requirements have been met (Box 1).

Box 1. Core capacity requirements for designated points of entry, Annex 1B of the International Health Regulations (2005)1.

1. At all times. The capacities:

a) to provide access to:

  • appropriate medical services, including diagnostic facilities to allow prompt assessment and care of ill travellers, and

  • adequate staff, equipment and premises;

b) to provide access to equipment and personnel for the transport of ill travellers to an appropriate medical facility;

c) to provide trained personnel for the inspection of conveyances;

d) to ensure a safe environment for travellers using points-of-entry facilities, including:

  • potable water supplies

  • eating establishments

  • flight catering facilities

  • public washrooms and

  • appropriate solid and liquid waste disposal services and other potential risk areas, by conducting inspection programmes as appropriate; and

e) to provide, as far as practical, a programme and trained personnel for the control of vectors and reservoirs in and near points of entry.

2. For responding to a public health emergency of international concern. The capacities:

a) to provide appropriate public health emergency response by establishing and maintaining a public health emergency contingency plan, including

  • the nomination of a coordinator, and

  • contact points for the relevant point of entry, public health and other agencies and services;

b) to provide assessments of and care for affected travellers or animals by:

  • establishing arrangements with local medical and veterinary facilities for their isolation, treatment and other support services that may be required;

c) to provide appropriate space, separate from other travellers, to interview suspect or affected persons;

d) to provide for the assessment and, if required, quarantine of suspect travellers, preferably in facilities away from the point of entry;

e) to apply recommended measures to:

  • disinsect

  • derat

  • disinfect

  • decontaminate, or

  • otherwise treat baggage, cargo, containers, conveyances, goods or postal parcels including, when appropriate, at locations specially designated and equipped for this purpose;

f) to apply entry or exit controls for arriving and departing travellers; and

g) to provide access to:

  • specially designated equipment, and

  • to trained personnel with appropriate personnel protection for the transfer of travellers who may carry infection or contamination.

The IHR (2005) recognize that Member States have the sovereign right to legislate and implement legislation. Nevertheless, article 3 states that legislation should uphold the purpose of the regulations.1 The majority of the United Kingdom’s overseas territories and crown dependencies were technically compliant with national legislation and requirements. However, the legislation was often outdated, which could also be the case for other overseas territories. Consequently, legislation should be reviewed to facilitate full and efficient implementation of the regulations, for example, to include an all-hazards approach. The lack of skilled personnel for reviewing and drafting legislation and the lack of finance are recognized as barriers to this task, therefore advice and support from appropriate experts may be required. The allocation of funding to support the implementation of the IHR (2005) is not explicitly a requirement for compliance, but if there is no specific budget – which was the case for most of the United Kingdom’s overseas territories and crown dependencies – it is difficult to complete the tasks required to achieve compliance.

Effective surveillance is paramount to an efficient and successful public health system and an effective capability for surveillance and response minimizes the risk of disease spreading across borders.6 Although all the United Kingdom’s overseas territories and crown dependencies were able to carry out routine surveillance as mandated under article 5 of the IHR (2005)1 (which concerns the detection, assessment, notification and reporting of events), some need to enhance their capabilities. The methods used to detect and report events will vary according to the nature of the overseas territory and its circumstances.

The ability to respond to a public health emergency is not strictly a requirement of the IHR (2005). Nevertheless, in order to respond effectively to both public health emergencies of international concern and other public emergencies, overseas territories need to develop plans to ensure a rapid response to all hazards, enlisting external support as appropriate. Moreover, WHO recommends that standard operating procedures be developed for case management in priority infectious diseases and for chemical and radionuclear events. Such procedures were generally available for infectious diseases, but not for chemical or radionuclear events in most of the United Kingdom’s overseas territories and crown dependencies. The use of standard case definitions increases the specificity of reporting and improves the comparability of events in different geographical areas.15 The majority of overseas territories would benefit from developing guidelines for the management of poisoning and chemical and radionuclear events. Observations in the United Kingdom’s overseas territories and crown dependencies indicate that it would probably be difficult to sustain a public health response during a disease outbreak.

It has been recognized that one of the main challenges in implementing the IHR (2005) is the presence of gaps in human resources14 and this was reflected in our assessment. Although there is no requirement for personnel to have a specific level of skill, WHO has recognized that a skilled public health workforce is essential for an effective health system.16,17 Self-assessments in these territories and dependencies indicated that there was a relative lack of staff with expertise in public health surveillance and response because of the small populations and remote locations. This is likely to be true for other overseas territories. It is also important to ensure that the requirements of the IHR (2005) can be satisfied not only during public health emergencies but also, for example, when personnel are on leave. In addition, where the turnover of staff is high, it is important to ensure that individuals with the necessary skills continue to be available. Training, perhaps remotely through web-based systems, is needed so that staff know how to detect, and respond to, public health emergencies.

Although none of the United Kingdom’s overseas territories or crown dependencies were able to test for all priority infectious hazards, gaps in testing capacity were addressed by collaboration with laboratories with additional resources outside the territory – this solution has previously been identified as a way of complying with the IHR (2005).15 Similar gaps are probably present in all overseas territories. Moreover, because of their remoteness, these territories will experience delays in processing samples when they are sent outside the territory. Consequently, it is recommended that overseas territories develop service agreements with collaborating laboratories so that the expected timelines are clear. Some of the United Kingdom’s overseas territories and crown dependencies encountered carriers that were concerned about transporting potentially hazardous samples by air. The safe and effective transportation of samples is a recognized problem in many parts of the world.14 It is recommended, therefore, that service agreements addressing the requirements of the International Air Transport Association for the safe shipment of biological specimens be drawn up and that triple packaging materials be readily available within overseas territories and crown dependencies.

Some questionnaire respondents felt that laboratory biosafety and security were not adequate. Further work should be undertaken on this issue even though it is not strictly necessary for compliance with the IHR (2005).

Conclusion

Smaller countries and territories face challenges in complying with the IHR (2005). However, the process provides them with an opportunity to build, strengthen and maintain core capacities for public health surveillance and response.18 In addition, any assessments carried out can be used to provide baseline data for monitoring future improvements in public health systems. In the United Kingdom’s overseas territories, there was a good understanding of what is required to implement the IHR (2005) and many territories had already undertaken a substantial amount of work to ensure compliance. Nevertheless, knowledge of the regulations and their implications was not strong in some overseas territories, particularly in those where personnel changed each year. This is likely to be the case in many overseas territories.

Successful implementation of the IHR (2005) necessarily involves a realistic assessment of shortcomings.14 Globally, it is assumed that all parts of the territory of WHO Member States are compliant with the regulations with regard to public health surveillance and response. However, this assumption is not realistic for overseas territories because they are dispersed geographically over a vast area. Although the assessment we undertook for the United Kingdom’s overseas territories fulfilled the purpose of evaluating compliance with IHR (2005),16 it relied on self-assessment rather than on independent evaluation, which may have resulted in bias. To ensure that all parts of the territory of WHO Member States comply with IHR (2005), countries with overseas territories should carry out similar assessments. Subsequently, all overseas territories should develop action plans to address areas in which they are not currently compliant. There is, however, no single model appropriate for all overseas territories because they vary greatly in geography, population, health service capabilities and disease epidemiology.

In conclusion, although overseas territories are likely to be largely compliant with IHR (2005), as the United Kingdom’s overseas territories were, there will be gaps that need to be bridged to ensure global public health security.
