Disaster management plans have traditionally been required to manage major traumatic events that create a large number of victims. Infectious diseases, whether they be natural (e.g. SARS [severe acute respiratory syndrome] and influenza) or the result of bioterrorism, have the potential to create a large influx of critically ill into our already strained hospital systems. With proper planning, hospitals, health care workers and our health care systems can be better prepared to deal with such an eventuality. This review explores the Toronto critical care experience of coping in the SARS outbreak disaster. Our health care system and, in particular, our critical care system were unprepared for this event, and as a result the impact that SARS had was worse than it could have been. Nonetheless, we were able to organize a response rapidly during the outbreak. By describing our successes and failures, we hope to help others to learn and avoid the problems we encountered as they develop their own disaster management plans in anticipation of similar future situations.

Beginning in the 1950s respiratory viruses have been gradually discovered by isolation in cell cultures The last were the coronaviruses in the 1960s. No new respiratory viruses were discovered until 2001 when human metapneumovirus was found in respiratory specimens from children with bronchiolitis. A year later, in November 2002, severe acute respiratory syndrome (SARS) suddenly appeared as atypical pneumonia. A novel virus belonging to the Coronaviridae family was found to be a cause of this infection. In 2004, a second coronavirus was discovered (CoV-NL63) and in 2005 a third new coronavirus was described (CoV-HKU1). In addition, several subtypes of the influenza A virus, previously known to infect only poultry and wild birds, were recently found to have been directly transmitted to humans. Respiratory infection has been a considerable problem for humans for centuries. Now, in the 21st century, with new associated viruses continuously emerging, it remains an important field for work.

In the future, transfer of vital sensor data from patients to the public health care system is likely to become commonplace. Systems for automatic transfer of sensor data are now at the prototype stage. As electronic health record (EHR) systems adapt such functionality, widespread use may become an actuality in the foreseeable future.To prevent spreading of diseases, an early detection of infection is important. At the time an outbreak is diagnosed, many people may already be infected due to the incubation period. This study suggests an approach for detecting an epidemic outbreak at an early stage by monitoring blood glucose data collected from people with diabetes. Continuous analysis of blood glucose data may have the potential to prevent large outbreaks of infectious diseases, such as different strains of Influenza, Cholera, Plague, Ebola, Anthrax and SARS.When a person gets infected, the blood glucose value increases. If the blood glucose data from a large number of patients with diabetes are collected in a central database, it may be possible to detect an epidemic disease outbreak at an early stage. Advanced data analysis on the data may detect predominant numbers of incidences, indicating a possible outbreak. This gives the health authorities the possibilities to take actions to limit the outbreak and its consequences for all the inhabitants in an affected area.At the Norwegian Centre for Telemedicine, a mobile system for automatic transfer of blood glucose values has been constructed. By using wireless communication standards such as Bluetooth and GSM, the system transfers blood glucose data to an electronic health record system. Combined with a system accessing and querying data from EHR systems for patient surveillance we are extending our work into an Epidemic Disease Detection using blood Glucose (EDDG) system.

The German Field Epidemiology Training Programme (FETP) and the European Programme for Intervention Epidemiology Training (EPIET) were founded to develop a network of epidemiologists for the surveillance and control of communicable diseases. During their 2-year training, FETP or EPIET fellows are based at the Robert Koch-Institut or other European host institutes and have to conduct outbreak investigations, carry out surveillance and research projects and publish the results. Since 1995, all 22 FETP and 94 EPIET fellows have conducted and published numerous outbreak investigations, surveillance and research projects, for example on pathogens inducing salmonellosis, influenza, SARS or avian influenza. Currently, 70% of FETP and EPIET alumni are working in key positions in communicable disease control on a regional, national or international level. The German FETP and the European EPIET programme offer high quality practical training in applied epidemiology. The expert knowledge of the alumni of both training programmes will be incorporated into the new European Centre for Disease Control (ECDC) and determine the future direction of infectious disease epidemiology in Germany and Europe.

Bioethics apparently suffers from a misdistribution of research resources analogous to the '10/90' divide in medical research. Though infectious disease should be recognized as a topic of primary importance for bioethics, the general topic of infectious disease has received relatively little attention from the discipline of bioethics in comparison with things like abortion, euthanasia, genetics, cloning, stem cell research, and so on. The fact that the historical and potential future consequences of infectious diseases are almost unrivalled is one reason that the topic of infectious disease warrants more attention from bioethicists. The 'Black Death' eliminated one third of the European population during the 14th Century; the 1989 flu killed between 20 and 100 million people; and, in the 20th Century smallpox killed perhaps three times more people than all the wars of that period. In the contemporary world, epidemics (AIDS, multi-drug resistant turberculosis, and newly emerging infectious diseases such as SARS) continue to have dramatic consequences. A second reason why the topic of infectious disease deserves further attention is that it raises difficult ethical questions of its own. While infected individuals can threaten the health of other individuals and society as a whole, for example, public health care measures such as surveillance, isolation, and quarantine can require the infringement of widely accepted basic human rights and liberties. An important and difficult ethical question asks how to strike a balance between the utilitarian aim of promoting public health, on the one hand, and libertarian aims of protecting privacy and freedom of movement, on the other, in contexts involving diseases that are--to varying degrees--contagious, deadly, or otherwise dangerous. Third, since their burden is most heavily shouldered by the poor (in developing countries), infectious diseases involve issues of justice--which should be a central concern of ethics. I conclude by providing sociological and historical explanations of why the topic of infectious disease has not already received more attention from bioethicists.

Linear peptides derived from the HIV gp41 C-terminus (C-peptides), such as the 36-residue Fuzeon, are potent HIV fusion inhibitors. These molecules bind to the N-peptide region of gp41 and inhibit an intramolecular protein-protein interaction that powers fusion of the viral and host cell membranes. The N-peptide region contains a surface pocket that is occupied in the post-fusion state by three alpha-helical residues found near the gp41 C-terminus: Trp628, Trp631, and Ile635-the WWI epitope. Here, we describe a set of beta3-decapeptides (betaWWI-1-4) in which the WWI epitope is presented on one face of a short 14-helix stabilized by macrodipole neutralization and side chain-side chain salt bridges. betaWWI-1-4 bind in vitro to IZN17, a validated gp41 model, and inhibit syncytia formation in cell culture. Molecules lacking a complete WWI functional epitope neither bind IZN17 nor inhibit syncytia formation. These results provide evidence that short beta-peptide 14-helices can inhibit an intramolecular protein-protein interaction in vivo. Molecules related to betaWWI-1-4 could represent starting points for the development of highly potent inhibitors or antigens effective against HIV or other viruses, including SARS, Ebola, HRSV, and influenza, that employ common fusion mechanisms.

Recent public health emergencies involving anthrax, the severe acute respiratory syndrome (SARS), and shortages of influenza vaccine have dramatized the need for restrictive public health measures such as quarantine, isolation, and rationing. Front-line physicians will face ethical dilemmas during public health emergencies when patients disagree with these measures. Patients might request interventions that are not recommended or for which they are not eligible, or they might object to intrusive or restrictive measures. The physician's primary responsibility in such emergencies is to the public rather than to the individual patient. In public health emergencies, physicians need to address the patient's needs and concerns, recognize their changed roles, and work closely with public health officials. Physicians can still work on behalf of patients by advocating for changes in policies and exceptions when warranted and by mitigating the adverse consequences of public health measures. Before an emergency occurs, physicians should think through how they will respond to foreseeable dilemmas arising when patients disagree with public health recommendations.

In late 2003 and early 2004 the ACT Division of General Practice and ACT Health conducted two concurrent surveys designed to identify knowledge, attitudes and practices of Australian Capital Territory (ACT) general practitioners around severe acute respiratory syndrome (SARS) and biothreat preparedness. One survey asked individual general practitioners (GPs) about how they gathered information about SARS in 2003, how they preferred to receive information, current practices, and how they perceived the threat of SARS and other infectious agents. The second survey asked practice principals how they organised their practice to respond to the SARS threat in 2003, any difficulties they had with implementing this response, use of SARS infection control guidelines and current policies. The response rate for the individual GP survey was 48 per cent (184/381) and the response rate for the practice organisation survey was 54 per cent (74/136). GPS used many sources of information on SARS during the 2003 outbreak. Facsimiles from the ACT Division of General Practice were the primary source (17%) and facsimile was the preferred method of receiving information in future outbreaks. The majority of GP respondents felt adequately informed about SARS during the 2003 outbreak, but many general practices did not follow the national guidelines on telephone screening of patients, warning signs and having infection control kits available. The majority of practices reported that they had policies or procedures in place to isolate potentially infectious patients from others in the waiting room. GPs rated an influenza pandemic as a threat to themselves and their patients much more highly than SARS or bioterrorism. Suggestions and comments on how ACT GPs could be better prepared to respond to future outbreaks included the need for timeliness of information, information delivery mechanisms, communication issues, education, the availability of guidelines and protocols, planning, role delineation, the use of response teams, provision of equipment, and vaccination. Planning for future infectious disease outbreak events in the Australian Capital Territory should incorporate general practitioners so that the plans reflect what is a feasible response in the general practice setting.

Measures of genetic distance based on alignment methods are confined to studying sequences that are conserved and identifiable in all organisms under study. A number of alignment-free techniques based on either statistical linguistics or information theory have been developed to overcome the limitations of alignment methods. We present a novel alignment-free approach to measuring the similarity among genetic sequences that incorporates elements from both word rank order-frequency statistics and information theory. We first validate this method on the human influenza A viral genomes as well as on the human mitochondrial DNA database. We then apply the method to study the origin of the SARS coronavirus. We find that the majority of the SARS genome is most closely related to group 1 coronaviruses, with smaller regions of matches to sequences from groups 2 and 3. The information based similarity index provides a new tool to measure the similarity between datasets based on their information content and may have a wide range of applications in the large-scale analysis of genomic databases.

The mannose binding proteins on the surface of the dendritic cells are responsible for capture of pathogens in the early stages of immune response. Conjugation to mannose dendrimers is a rarely explored but potentially powerful strategy for enhancing immunogenicity of synthetic peptides relying on direct delivery to dendritic cells. We describe a general protocol for preparation of pure, monodisperse third-generation mannosylated poly-L-lysine dendrimer-peptide conjugates using direct, machine-assisted Fmoc/t-Bu solid phase peptide synthesis. The glycodendrons were elaborated onto the N- or C-terminus of sequences derived from HIV-1 gp41, SARS-CoV S2 protein, and Influenza Hemagglutinin (consisting of 15-44 residues). The products were obtained in a homogeneous state after cleavage from the resin, deprotection, and a single purification on semipreparative RP-HPLC.
