In addition, after casualties, due to limited conditions, in the case of high temperature and more rain, the body will rot, which will cause more problems, such as stench and environmental pollution. Judging from this situation, there are several problems:
The water source may be polluted.
Water supply mainly depends on centralized water supply and decentralized water supply after water intake. If you bring water to drink directly, the water source may be damaged and polluted by pollutants, including some stones, bricks, tiles, blocks and so on. When the house collapsed, there were still some rotting bodies or feces. During an earthquake, wells often have some changes. During the Tangshan earthquake, some wells were black and undrinkable. Pollutants will flow into the water system, making the water source unable to be used normally.
Food pollution problem
Because there is no food, there may be some rotten food, but they will still eat it to save lives. In this case, eating rotten food will cause mold and bacterial infection, which will lead to many intestinal infections, such as diarrhea, enteritis, diarrhea, dysentery and so on. After these situations happen, if they are not handled properly, the water source will be polluted and the drinking water will spread again. Therefore, when an epidemic breaks out, especially during a major epidemic, firstly, intestinal infection is a very serious matter. In addition, the collapse of buildings has affected the health of animals and food, which is everywhere. Because animals want to eat, they may eat some rotten things, spread germs to other places, and there may be plagues.
Fly harm
If the temperature is too high, flies will multiply rapidly, and rotten things after reproduction, including plants, animals and food, will spread into people's food, leading to an increase in diarrhea. There are mosquitoes. Mosquitoes stare at the patient and then at the second person, which will spread germs. From these aspects, for the current Wenchuan earthquake, one thing that needs attention is diarrhea. Because the body temperature is not very high, other symptoms have not come out, and diarrhea is very concerned.
For example, during the Tangshan earthquake, the data showed that in the initial stage, the incidence of diarrhea was higher than usual 10%-30%. Of course, the source of the disease was controlled at that time. We think that at this time, preventing diarrhea is the first priority. In addition, it is necessary to prevent the breeding of vectors, including flies, mosquitoes and plagues. We must cut these off at the source.
