Effects of a natural disaster on immigrants and host population.

The psychosocial effects of the 1989 Newcastle earthquake on 250 immigrants from non-English-speaking backgrounds (NESB) were compared with a matched sample of 250 Australian-born subjects. The NESB subjects had higher levels of both general (General Health Questionnaire-12) and event-related (Impact of Event Scale) psychological morbidity. Furthermore, NESB females had the highest levels of distress, particularly those who were older on arrival in Australia and those who experienced high levels of disruption. The results suggest that NESB immigrants, particularly women, appear to be more at risk for developing psychological distress following a natural disaster. However, level of exposure and an avoidance coping style contributed more substantially to psychological distress than ethnicity.

Post-traumatic stress disorder: supportive evidence from an eighteenth century natural disaster.

Post-traumatic stress disorder was first recognized as a diagnostic category embracing reactions in response to overwhelming environmental stress 'outside the range of usual human experience' in DSM-III (APA, 1980). Such abnormal stressors are by no means a product of the twentieth century but have featured, sporadically, in all societies from the earliest civilizations. Longitudinal investigations of traumatic stress have rarely gone further back than the nineteenth century, and have been concerned, almost exclusively, with adverse effects following railway accidents and military combat. The present study, utilizing a mid-eighteenth century medical source, presents an analysis of the impact of a natural disaster on members of a peasant family trapped in an avalanche in the Italian Alps in 1755.

Acute posttraumatic stress disorder in victims of a natural disaster.

Five months after a tornado devastated a rural community in eastern North Carolina, the authors surveyed the mental health status of 116 disaster victims, using the Hopkins Symptom Checklist (HSCL) expanded to include most of DSM-III criteria for posttraumatic stress disorder (PTSD). A total of 69 (59%) victims met the criteria for acute PTSD, 19 of whom had a severe form. Although an inadequate degree of social support was more often noted in victims with severe PTSD, other demographic factors and degree of injury or property damage did not appear to be related to the presence of PTSD. Severity or presence of PTSD was supported by high scores on all HSCL subscale factors. These findings suggest a high incidence of acute PTSD in victims of natural disasters and the potential value of HSCL in screening for PTSD in large populations.

The impacts of climate change on the risk of natural disasters.

Human emissions of greenhouse gases are already changing our climate. This paper provides an overview of the relation between climate change and weather extremes, and examines three specific cases where recent acute events have stimulated debate on the potential role of climate change: the European heatwave of 2003; the risk of inland flooding, such as recently in Central Europe and Great Britain; and the harsh Atlantic hurricane seasons of 2004 and 2005. Furthermore, it briefly assesses the relation between climate change and El Niño, and the potential of abrupt climate change. Several trends in weather extremes are sufficiently clear to inform risk reduction efforts. In many instances, however, the potential increases in extreme events due to climate change come on top of alarming rises in vulnerability. Hence, the additional risks due to climate change should not be analysed or treated in isolation, but instead integrated into broader efforts to reduce the risk of natural disasters.

Long-term psychiatric morbidity after a natural disaster. Implications for disaster planners and emergency services.

The prevalence and longitudinal course of post-traumatic stress disorder were studied in a group of 459 firefighters who were exposed to the Ash Wednesday bushfires in South Australia. The main finding, that the level of morbidity four months after the disaster remained almost unchanged at 29 months, indicates the long-term nature of post-traumatic stress disorder. Twenty-nine months after the fire, 21% of the firefighters were continuing to experience imagery of the disaster, in a way that interfered with their lives. The failure of present disaster management plans to recognize the psychological impact of natural disasters and the long-term nature of post-traumatic stress disorder is emphasized, and the need for preventive mental health programmes to minimize such morbidity in the future is discussed.

Natural disasters in the United States as release agents of oil, chemicals, or radiological materials between 1980-1989: analysis and recommendations.

Generally, hazards research and literature has treated natural and technological disasters as separate entities. This study attempts to determine how frequently interaction between these two types of disaster took place in the United States from 1980-1989. Data were collected by performing a literature review, contacting organizations and individuals active in hazards research and mitigation, and through a questionnaire sent to the emergency management agencies of all 50 states. The consensus derived from the data is that the number of incidents where natural and technological disasters interact is rising while preparations, which recognize the complications inherent in such combined events, remain cursory. There is a pressing need for states to record, and make available to managers, information regarding the number of combined natural/technological events affecting their areas. Only when such data are available will it be possible to make appropriate decisions regarding the best way to reduce the effects of a natural disaster causing a catastrophic release of hazardous materials.

[The role of the veterinarian during natural disasters].

After a reminder of the main types of natural hazards that can lead to genuine disasters, the author examines the impact of such disasters on animal health. The conceptual approach to various groups of animals in a disaster situation is explained, as well as the direct and indirect effects of such disasters. Preparatory measures are presented within the general framework of prevention and forecasting, together with the veterinary measures to be implemented. Training of veterinarians and planning of activities are described in detail. A traditional approach to organising large-scale assistance is advocated, based on the competence of the personnel involved and a predefined hierarchical organisation. The author then describes veterinary actions to be taken in a disaster situation where emergency aid is required. Particular reference is made to providing assistance to save human lives, including search operations by dog teams for buried victims, and the subsequent phase of restoring human activities, during which assistance to animals is taken into account. Inter-ministerial co-ordination using crisis units and priority management implying real political choices are discussed. Finally, based on the example of the operational organisation of the French Civil Defence, the author describes the support available to Veterinary Services and the potential involvement of the profession, in particular veterinary officers attached to the emergency fire service.

[The status of immunity in the victims of industrial catastrophes and natural disasters].

The influence of industrial catastrophes or calamities upon human organism is accompanied by the affection of the immunity system. The structure and manifestations of immunity disorders depend on nature of the disturbing factors in every concrete catastrophe. The affections of the immunity system may lead to the formation of secondary immunodeficiency which will require additional medical assistance.

Shaking up immunity: psychological and immunologic changes after a natural disaster.

OBJECTIVE: The 1994 Northridge earthquake created life disruption and psychological distress for employees of the nearby Sepulveda VA Medical Center. We were interested in the immunologic correlates of disruption and distress under these stressful circumstances. METHOD: Sixty-eight employees were examined beginning 11 days post-earthquake and were observed until about 4 months after the earthquake, during which time three psychological and immunologic assessments were done. Subjects experienced life disruption from the earthquake itself, damage to home and possessions, injury to self and others, and damage to and functional disruption of workplace. Questionnaires assessed degree of life disruption (personal and work-related), mood, earthquake-specific distress, and repression (alexithymia, coping style or "Type C", and "immunosuppression-prone" traits). Immune measures included lymphocyte subsets-total T (CD3+), helper T (CD4+), cytotoxic T (CD3 + CD8+), B (CD19+), and natural killer (NK; CD3 - CD16 + CD56+)-as well as lymphoid cell mitogenesis (PHA and PWM), and NK cell cytotoxicity. RESULTS: Along with a lessening degree of distress over time, a number of immunologic measures declined over the assessment period (CD3+, CD8+, CD16 + 56+ cells. T cell blastogenesis, and NK cell cytotoxicity). Furthermore, subjects reporting low distress had higher numbers of CD3+ and CD8+ cells and a higher proliferative response to PHA. Those with distress corresponding to life disruption had highest levels of CD3+ and CD8+ cells. Measures of repression did not relate directly to immunity. CONCLUSION: These results suggest that appropriateness of psychological reaction to the realistic degree of life stress was least disruptive of an aspect of immunity.

Dealing with the continuing challenges of natural disasters.

Tropical Storm Allison--which struck the Texas and Louisiana coasts in June 2000--killed 22 people, flooded more than 27,000 homes, and caused an estimated $2 billion in property damage in the Houston area alone. Among the hardest hit were some 12 hospitals in the Texas Medical Center, south of downtown Houston, the world's largest medical facility, which all experienced flooding and reduction of services to various degrees. (The medical complex of 42 member institutions also includes numerous academic buildings and research laboratories where nearly 35,000 lab animals drowned.) Two of the hospitals were forced to evacuate all patients and close after losing emergency power. Sixteen patients died at medical center facilities during the storm, but a team from the JCAHO reportedly found that the deaths were caused by the critical nature of their illnesses rather than the severe flooding that inundated basements and other areas of the medical center.
