Effective disaster mitigation is the foundation for efficient disaster response and rescue and for reducing the degree of hazardous impacts on the population.
A hazard vulnerability assessment HVA systematically evaluates the damage that could be caused by a potential disaster, the severity of the impact, and the available medical resources during a disaster to reduce population vulnerability and increase the capacity to cope with disasters.
We further discussed the role of epidemiology in an HVA. Disaster epidemiology studies the underlying causes of disasters to achieve effective disaster prevention and reduction.
In addition, we made several recommendations that are already in practice in developed countries, such as the U. An effective HVA plan is crucial for successful disaster preparedness, response, and recovery.
Vulnerability, Hazard vulnerability assessment, Disaster epidemiology, Disaster preparedness Background Disasters occur frequently and often place a substantial burden on affected populations. Disasters are defined as singular large-scale events that cause serious disruptions of the function of a community or a society and involve human, material, economic or environmental losses or impacts.
Disasters are the product of a combination of hazards and vulnerability. Hazards that strike in areas with low vulnerability will not become disasters [ 1 ]. However, most hazards occur in developing or underdeveloped regions or in areas with a high population density, poor infrastructure, and a limited or no disaster preparedness plan.
Comparing to developed countries, such as the U.
There is a significant gap between the knowledge level of and skills for disaster medicine and the current needs of disaster preparedness [ 2 ]. High vulnerability and insufficient disaster preparedness plans have severe consequences.
For example, during the SARS outbreak, without an effective HVA on emerging infectious diseases, some Chinese hospitals could not effectively response to this severe infectious disease and fell into crisis. More recently, the Eastern Star yacht, which was carrying more than people, sank overnight in the Yangtze River during a cyclone in southern China, and only eight people were rescued.
The causes were extreme weather conditions and possible human error. It is important for China to learn about successful experiences and current best practices and to integrate available resources to set up systematic and functional disaster preparedness plans.
In this article, we focused on the hazard vulnerability assessment aspect, which is almost nonexistent in China, in relation to disaster preparedness. In combination with our own work in disaster medicine, we emphasized the epidemiological component of the hazard vulnerability assessment.
Vulnerability represents the susceptibility of a given population to harmful effects from exposure to hazardous events.
It directly affects disaster preparation, response, and recovery [ 4 ]. Hazardous event can directly or indirectly affect the health status of an individual or a population.
Different populations have different levels of vulnerability to a hazardous event that depend on multiple uncertain factors, including hazard intensity, environment, and population characteristics [ 5 ]. Environmental and population characteristics are system-resistance factors related to population vulnerability level.
Environmental factors can amplify or mitigate the destructive power of a hazardous event.Emergency preparedness and Vulnerability assessment.
Introduction The residents were given warning in advance that would have enabled to evacuate from the path of the storm in advance. A risk assessment is a process to identify potential hazards and analyze what could happen if a hazard occurs. A business impact analysis (BIA) is the process for determining the potential impacts resulting from the interruption of time sensitive or critical business caninariojana.com are .
Kaiser Permanente has developed a Hazard Vulnerability Analysis tool which is available for download as a planning resource. Individuals or organizations using this tool are solely responsible for any hazard assessment and compliance with applicable laws and regulations. A hazard identification and risk assessment provides the factual basis for activities proposed in the strategy portion of a hazard mitigation plan.
An effective risk assessment informs proposed actions by focusing attention and resources on the greatest risks. Emergency Operation Plan Development from a Vulnerability Assessment Perspective Learn how to construct a locally tailored all hazards crisis plan based on the hazard and vulnerability assessment .
