Estimating in real time the efficacy of measures to control emerging communicable diseases.

Controlling an emerging communicable disease requires prompt adoption of measures such as quarantine. Assessment of the efficacy of these measures must be rapid as well. In this paper, the authors present a framework to monitor the efficacy of control measures in real time. Bayesian estimation of the reproduction number R (mean number of cases generated by a single infectious person) during an outbreak allows them to judge rapidly whether the epidemic is under control (R < 1). Only counts and time of onset of symptoms, plus tracing information from a subset of cases, are required. Markov chain Monte Carlo and Monte Carlo sampling are used to infer the temporal pattern of R up to the last observation. The operating characteristics of the method are investigated in a simulation study of severe acute respiratory syndrome-like outbreaks. In this particular setting, control measures lacking efficacy (R > or = 1.1) could be detected after 2 weeks in at least 70% of the epidemics, with less than a 5% probability of a wrong conclusion. When control measures are efficacious (R = 0.5), this situation may be evidenced in 68% of the epidemics after 2 weeks and 92% of the epidemics after 3 weeks, with less than a 5% probability of a wrong conclusion.

[Changing patterns of communicable diseases in Korea].

Before twentieth centuries and during early twentieth centuries, communicable diseases were the major cause of morbidity and mortality in Korea. But reliable data are not available. After 1975, the overall morbidity and mortality from communicable diseases, rapidly declined. Recently many new pathogenic microbes were recognized: L. monocytogenes, Hantaan virus, Y. pseudotuberculosis, P. multocida, L. pneumophilia, Human immunodeficiency virus (HIV), G. seoi, H. capsulatum, C. burnetii, V. cholerae 0139, C. parvum, F. tularensis, E. coli 0157:H7, B. burgdorferi, S. Typhimurium DT104, Rotavirus, hepatitis C virus and so on. Since the first HIV infection recognized in 1985, the reported cases of infection and deaths from HIV/AIDS have been steady increased each year. Legionnaire's disease, E. coli 0157:H7 colitis, listeriosis and crytosporidiasis have been occurring just sporadically among immunocompromized cases. Many re-emerging communicable diseases were occurred in Korea: leptospirosis, malaria, endemic typhus, cholera, tsutsugamushi disease, salmonellosis, hepatitis A, shigellosis, mumps, measles, acute hemorrhagic conjunctivitis, brucellosis and so on. Leptospirosis and tsutsugamushi diseases have been noticed as major public health problems since 1980s. The malaria that had been virtually disappeared for a decade has reappeared from 1993 with striking increase of patients in recent 3-4 years. The distributions of salmonella and shigella serotypes have been changed a lot in recent few decades. Furthermore rapid emergence of antibiotic-resistant bacterial strains induces more difficult and complex problems in control of communicable diseases. We must recognize on the importance of environment and ecosystem conservation and careful prescription of anti-microbial agent in order to prevent communicable diseases.

Communicable diseases in complex emergencies: impact and challenges.

Communicable diseases, alone or in combination with malnutrition, account for most deaths in complex emergencies. Factors promoting disease transmission interact synergistically leading to high incidence rates of diarrhoea, respiratory infection, malaria, and measles. This excess morbidity and mortality is avoidable as effective interventions are available. Adequate shelter, water, food, and sanitation linked to effective case management, immunisation, health education, and disease surveillance are crucial. However, delivery mechanisms are often compromised by loss of health staff, damage to infrastructure, insecurity, and poor co-ordination. Although progress has been made in the control of specific communicable diseases in camp settings, complex emergencies affecting large geographical areas or entire countries pose a greater challenge. Available interventions need to be implemented more systematically in complex emergencies with higher levels of coordination between governments, UN agencies, and non-governmental organisations. In addition, further research is needed to adapt and simplify interventions, and to explore novel diagnostics, vaccines, and therapies.

A survey of emergency department communicable disease reporting practices.

A group of physicians, nurses, and administrators at all 11 hospitals in the District of Columbia were interviewed to elucidate each hospital emergency department's (ED) system for patient and public health notification of the diagnosis of legally reportable communicable diseases. The hospitals' reporting systems were divided into two groups. Three hospitals (27%) had reporting systems that were centered in the emergency department (EDS). Eight hospitals (73%) had disease reporting systems that depended primarily on extradepartmental personnel (HBS) for disease reporting. The EDS outperformed the HBS in several key areas of system performance. Greater attention needs to be paid by ED directors to assuring that their hospital's system is as accurate as possible and fulfills their jurisdiction's legal requirements for communicable disease reporting.

Commentary: Emerging and other communicable diseases.

There is an increasing need for integrated, sustainable; and cost-effective approaches to the management of infectious diseases. For example, an emerging disease in one country may already be endemic in another country but nearing elimination in a third. A coordinated approach by WHO towards infectious diseases is therefore needed that will facilitate more effective support of on-going efforts for the prevention and control of endemic diseases, intensify efforts against those diseases targeted for eradication and elimination, and result in better preparedness and response to new and re-emerging diseases. In order to meet these challenges, WHO has created a new Programme on Communicable Diseases (CDS), which will replace the former Division of Emerging and other Communicable Diseases (EMC). The new Programme will better integrate surveillance, prevention, control, and research over the whole spectrum of communicable diseases. CDS will function as focal point for global data and information exchange on infectious diseases, and inter alia, will reinforce laboratory-based surveillance of bacterial, viral, and zoonotic diseases to ensure early detection of threats to international public health. Changes in susceptibility to infectious disease, increased opportunities for infection, and the ability of microbes to adapt rapidly will continue to challenge WHO to improve prevention and control of infectious diseases in the future by establishing strong partnerships with both the private and public sectors.

SARS (severe acute respiratory syndrome): reflective practice of a nurse manager.

AIMS AND OBJECTIVES: This paper describes the reflective practice of a nurse manager in Hong Kong in supporting frontline nurses to overcome the crisis of SARS. BACKGROUND: SARS infection was a crisis for everyone in endemic areas because of its threat to physical and emotional health. Hong Kong was the second leading endemic area in the world. Inadequate supplies of protective devices and the death of a nurse infected with SARS triggered nurses' negative emotions. METHODS: A model of structured reflection was adopted to examine one's practice. A problem-solving model for crisis intervention was integrated into the reflective stage of structured reflection. RESULTS: Promotion of nurses' safety and emotional stability were the major goals in handling the crisis. Strategies were employed including self-awareness, empowerment and team building, information sharing, provision of personal protective equipment and emotional support for frontline nurses. CONCLUSIONS: SARS infection threatens the physical and emotional health of nurses. From a positive perspective, such a crisis created an opportunity to learn and grow in terms of ethical, personal and aesthetic arenas. RELEVANCE TO CLINICAL PRACTICE: SARS epidemic raised worldwide attention and challenged the Hong Kong's health care system. Reflective practice is useful to guide and examine nurses' professional action during the crisis, and to put the experience into a learning perspective.

Quality assurance for the diagnostics of viral diseases to enhance the emergency preparedness in Europe.

The threat posed by emerging and re-emerging communicable diseases and, more recently, by the intentional release of infectious agents in a susceptible population, has been receiving considerable attention at the national and international levels. Public health efforts to strengthen disease detection, surveillance and control have been intensified. However, clinicians and clinical microbiology laboratories play an important role in the early detection of disease, the identification of the putative agent, and notification of the appropriate authorities. To be effective in this role, laboratories must be specially prepared to handle viral agents safely, and need, among other things, the appropriate rapid and sensitive diagnostic tests. In 1998 the European Network for Diagnostics of 'Imported' Viral Diseases (ENIVD) was established. ENIVD presently comprises, as permanent members, 44 expert laboratories in 21 European Union (EU) member states and 4 non-EU countries and is one of the networks on infectious diseases funded by the European Commission. ENIVD fulfils many of the important tasks required for the surveillance and control of imported, rare and emerging viral infections such as the exchange of expertise and the organisation of external quality assurance (EQA) programmes, both of which are needed to improve diagnostics. Here, we summarise the data generated by recent EQA activities focussed on the diagnostics of infections with hantavirus, dengue virus, filovirus, Lassa virus, orthopox virus and the SARS-coronavirus (SARS-CoV). These were carried out between 1999 and 2004 and involved 93 laboratories from 41 countries, including laboratories from additional countries outside of Europe. Particularly the EU-candidate countries and Eastern neighbouring countries will be invited to join the network in the near future. A public website is available at http://www.enivd.de.

Use of sentinel laboratories by clinicians to evaluate potential bioterrorism and emerging infections.

With the persistent threat of emerging infectious diseases and bioterrorism, it has become increasingly important that clinicians be able to identify the diseases that might signal the occurrence of these unusual events. Essential to a thoughtful diagnostic approach is understanding when to initiate a public health investigation and how to appropriately use commonly performed microbiology procedures in the sentinel laboratory to evaluate potential pathogens. Although diagnostic test development is evolving rapidly, recognizing many of these pathogens continues to challenge the capabilities of most sentinel laboratories. Therefore, effective, ongoing communication and education among clinicians, infection control personnel, sentinel laboratorians, public health authorities, and Laboratory Response Network reference laboratorians is the key to preparedness.

Common themes in changing vector-borne disease scenarios.

The impact of climate change on disease patterns is controversial. However, global burden of disease studies suggest that infectious diseases will contribute a proportionately smaller burden of disease over the next 2 decades as non-communicable diseases emerge as public health problems. However, infectious diseases contribute proportionately more in the poorest quintile of the population. Notwithstanding the different views of the impact of global warming on vector-borne infections this paper reviews the conditions which drive the changing epidemiology of these infections and suggests that such change is linked by common themes including interactions of generalist vectors and reservoir hosts at interfaces with humans, reduced biodiversity associated with anthropogenic environmental changes, increases in Plasmodium falciparum: P. vivax ratios and well-described land use changes such as hydrological, urbanization, agricultural, mining and forest-associated impacts (extractive activities, road building, deforestation and migration) which are seen on a global scale.

Pediatric emergency physicians and communicable diseases: can we be trusted to take care of ourselves?

OBJECTIVE: To determine if pediatric emergency physicians (PEP) are following Centers for Disease Control and Prevention (CDC) recommendations that all health care workers receive routine vaccines and annual tuberculosis screens. DESIGN: A two-page mail survey with one follow-up mailing. PARTICIPANTS: All active members of the American Academy of Pediatrics (AAP), Section on Emergency Medicine. Additional inclusion criteria were completion of training and employment in an emergency setting. RESULTS: Of 407 surveys, 286 (60%) were returned; 209 met inclusion criteria. Proof of immunization was not required of 43% of PEP; 42% were not required to have an annual tuberculosis (TB) screen. PEP reported immunity to the following: polio (95%), measles (94%), hepatitis B (91%), rubella (90%), mumps (90%), varicella (90%), and diphtheria-tetanus (86%). However, only 72% received a TB screen, and 60% received an influenza vaccine within the past year. Proof of vaccination for employment was required by 57/85 hospitals, 47/79 universities, and 6/32 self-employed/group practices (chi 2, P < 0.001). Proof of an annual TB screen was required by 64/87 hospitals, 44/82 universities, and 8/32 self-employed/group practices (chi 2, P < 0.001). PEP were more likely to have had a recent annual TB screen if required by their employer (104/117) than if left to their own initiative (42/87) (chi 2, P < 0.001). CONCLUSIONS: Although PEP are well protected against most vaccine-preventable diseases, many are not receiving annual TB screens nor influenza vaccines. The CDC guidelines are not being routinely followed by PEP.
