Chapter 4 Post-disaster epidemic analysis and prevention-4

The relationship between natural disasters and infectious diseases is often misunderstood.People will think of infectious diseases from dead bodies, and worry that "there will be a great epidemic after the catastrophe."However, the risk of post-disaster outbreaks is primarily associated with population migration.The availability of clean water and sanitation, population density, the health status of the population itself, and the availability of appropriate medical services all interact with the local disease ecology and ultimately affect the risk of infectious disease outbreaks and the deaths of infected populations Rate.Here we summarize the risk factors for post-disaster epidemics, assess possible severe outbreaks, and sort out the priorities of post-disaster epidemic prevention work.

Natural disasters refer to catastrophes caused by atmospheric, geological or hydrological factors, including earthquakes, volcanic eruptions, mudslides, tsunamis, floods and droughts.Natural disasters can strike suddenly or slowly and have major impacts on safety and health, society and the economy.Over the past two decades, natural disasters have killed millions of people worldwide, affected the lives of more than a billion people and caused immeasurable economic losses.Developing countries that suffer from underfunding, poor infrastructure, and lack of pre-disaster contingency plans tend to be more traumatized by disasters.

Most of the deaths related to natural disasters, especially those caused by sudden disasters, are from crushing, crushing, or drowning.In contrast, deaths from infectious diseases after disasters are less common.
