All copies must retain all author credits and copyright notices included in the original document. Under no circumstances is it permissible to sell or distribute on a commercial basis, or to claim authorship of, copies of material reproduced from this publication. This material is intended for educational use only by practicing health care workers or students and faculty in a health care field. Thus, students, instructors and health professionals might be forced to search other materials/references for different outbreaks/epidemics when they are in need. This manual may reduce the problem of limited access to information on the principles of outbreak investigation, preparedness and response, management and monitoring of epidemic prone diseases in Ethiopia. This manual is prepared primarily for health science and medical students in universities. However, such manuals are not also available at regional health professional training institutions and health facilities. Different categories of health workers who are working in these facilities directly or indirectly i engaged in investigation and management of epidemics/outbreaks would be benefited from such material. Investigation of infectious disease outbreaks are commonly encountered in Ethiopia, and findings of such investigations are often published; however, surprisingly little has been written about the actual steps followed during such investigations and the detailed activities in the process. This manual, thus, attempts to outline the general approach to conduct an outbreak investigation, management along with investigation of specific infectious diseases of public health importance and the investigation of outbreaks in special settings. The primary motivation to write this manual came from the dire scarcity of practical manuals for health science and medical students to acquire the knowledge and skill of conducting outbreak investigation and management in the country. In addition, the same shortage of practical manuals for health workers and the very limited reference material for outbreak investigation in different settings ii have also inspired the authors to write this manual with the support of Ethiopia Public Health Training Initiative of The Carter Centre. The first chapter gives an overview of occurrence of disease and types of epidemics. The second chapter draws on the background given in chapter one and highlights and expatiates on the activities in epidemic investigation. In the same chapter management of epidemic is mentioned as one step leaving the detailed discussion of Epidemic management for the following chapter.

We highlight here the central role of public health initiatives in limiting the scale of that emergency in the first place generic 30 mg paxil overnight delivery medicine sans frontiers. In so doing cheap paxil 30mg otc medicine knowledge, they could both add weight to the arguments surrounding the role of government in promoting good public health purchase 30 mg paxil with mastercard treatment 02 binh, and also act to raise public awareness of the avoidable causes of some organ failure paxil 10mg line schedule 9 medications. As we have noted in several other contexts in this report, the position regarding gametes is rather different from that of organs. While it is broadly accepted that it is appropriate for the public health agenda to include consideration of diseases that may impact on later fertility, there is no such consensus that any state-sponsored organisation should seek to influence childbearing patterns, such as the age at which women have children. The factors that influence the age at which women have their first child are complex and many relate to social and economic issues well outside the range of this report. Nevertheless, we suggest that there is a potential role here for public health education and advice to improve awareness among women about the consequences of delaying childbearing. First we consider explicitly the role of the state in responding to the mismatch between demand and supply for bodily material in medicine and research. We have emphasised that the role of the stewardship state also includes taking action to minimise inequalities and to promote the welfare of those who would, without positive action, be excluded from benefits or services. In the context of donation, black and minority ethnic populations are significantly less likely to become donors (across a range of different forms of bodily material). We therefore suggest that a stewardship state has a direct responsibility to explore the reasons why some populations are hesitant to donate, and if appropriate to take action to promote donation. It is only too easy for any consideration of the donation of bodily materials to concentrate on their use in direct treatment, and overlook, or take as of secondary importance, their possible research uses. We state here our view that research, and the future health benefits that research seeks to bring, are of vital public interest. Much health-related research using tissue or healthy volunteers is, of course, carried out within the private (ie commercial) sector. Any commercial return would be many years after the initial donation, and the particular contribution of any individual would in most circumstances, be impossible to measure. We suggest therefore, that although it is clearly just that commercial companies in such circumstances should seek in some way to share the financial benefits of their research more widely, such benefit-sharing should take place in a wider context, rather than in response to the financial potential of bodily material from particular individuals. Two potential ways in which such benefit-sharing or partnership might emerge include: first, active financial support from the commercial sector for tissue banks as a public good for researchers from all sectors; and second, the development of ongoing relationships between tissue donors and the research teams (whether in the public, voluntary or commercial sector) whose work depends on access to their samples. Third, questions of what is public and what is private also apply to the question of the potential for property rights in bodies and body parts. While the legislative frameworks of the Human Tissue Act and the Human Fertilisation and Embryology Act provide mechanisms for safeguarding some aspects of donors rights, particularly with respect to consent, they are far from complete. Finally, we raise the question of public interest in the issue of cross-border health care and questions of national self-sufficiency. We further emphasise the importance of concerted action being taken to enforce this stance, so that such practices cannot continue with impunity. The situation, however, is potentially rather different where the activities in question for example the selling of gametes are perfectly legal in the country of origin. Concerns about individual liberty make it hard to imagine circumstances in which individuals seeking treatment that is lawful in the destination country should be prevented from travelling. The specific treatment of the individual abroad remains the responsibility of the local professional team. Regulatory bodies such as the General Medical Council should maintain general oversight in this area, in the same way as they oversee other aspects of professional standards. We recommend that the World Health Organization should develop appropriate guiding principles to protect egg donors from abuse or exploitation. We have already argued that the state has a stewardship role in maximising the donation of bodily materials, where these have the potential to contribute to improved health, and within ethical limits. To that extent, and no further, the aim of national self-sufficiency is clearly laudable. However, where this national self-sufficiency cannot be achieved without taking action that would otherwise be regarded as unethical, the fact that people may still choose to travel abroad should not force a change of policy. Barriers to blood donation are not, of course, only physical, and as in organ donation there may be other factors hindering particular communities from feeling able to donate. We commend here the work of the National Blood Service and the African Caribbean Leukaemia Trust, for example, in initiatives such as Daniel De-Gale week, to encourage both blood and bone marrow donation from black and mixed race communities. We note the growing evidence as to the potential value of publicly-accessible sources of stem cells, and the procedures recommended by the Royal College of Obstetricians and Gynaecologists to protect the welfare of mothers and babies where donation of cord blood is considered. Such an approach was at the heart of the recommendations made by the Organ Donation Taskforce. The Working Party endorses the Organ Donation Taskforces focus on tackling the structural problems that have, in the 18 H u m a n b o d i e s : d o n a t i o n f o r m e d i c i n e a n d r e s e a r c h past, hindered the optimal use of the organs that are potentially available. There is clearly a risk that, in the face of such organisational changes and pressure on budgets, valuable systemic improvements that have led in recent years to significant increases in the number of organs made available for transplantation might be lost. We recommend that the Department of Health should monitor closely the impact of these changes on organ donation services, and be prepared if necessary to act to protect systems that have been shown to work well. We note that this is a highly complex area, and that we have not been in a position to collect evidence on this issue that might enable us to make specific recommendations as to appropriate actions. We therefore limit ourselves here to highlighting what we believe is an important ethical position: the relevance of our notion of the stewardship role of the state. That stewardship role includes a duty to take positive action to remove inequalities that affect disadvantaged groups or individuals. We endorse the call of the Race Equality Foundation for a clear strategy and action plan to take forward the lessons emerging from the research in this field. While considerable effort has gone into improving cooperative working in the area of organ transplantation, such cooperation does not necessarily extend across different fields of donation. We suggest that routine information about the Organ Donor Register should include explicit reference to the 19 H u m a n b o d i e s : d o n a t i o n f o r m e d i c i n e a n d r e s e a r c h potential research uses of organs and tissue, and that potential donors should have the option of authorising such uses in advance. We recognise that there are some concerns among transplant professionals that such requests risk distressing families, leading to their refusing to agree to a transplant that they might otherwise have granted. Others argue that, if properly approached, families appreciate the potential value of contributing to research. Should such a pilot scheme prove successful, we recommend that the possibility of donating for research purposes (distinguishing between research as part of the transplantation process, and research undertaken with material that would otherwise not be used for transplantation) should be included within the standard consent/authorisation documentation for deceased donation. Finally on the issue of organ donation, we note the importance of robust information systems both in ensuring proper use of donated material and in maintaining trust among the general public. It should not be the case that the publics willingness to donate is undermined by information technology systems that are unable to account accurately for potential donors preferences. Considerable access issues, however, are reported in connection with tissue for research use, despite apparent willingness on the part of both patients and members of the public to donate if asked to do so. Factors cited as problematic include concerns around the use of generic consent; a lack of willingness at times to share samples and their associated data; funding difficulties; and licensing and governance arrangements that were perceived to be disproportionate and overlapping. This recommendation applies equally where researchers are seeking consent for a specific research project: additional generic consent should also be sought, so that any material not used up in the initial project may be made available for other research use via a tissue bank.
