The harm of flood
Flood is a natural disaster, which will bring great losses to people's lives and property. Floods can destroy houses, roads, bridges and farmland, leaving people homeless, with no way to go and no food to eat. At the same time, the flood will also bring some other hazards, such as soil erosion, water pollution, pathogen transmission and so on.
Reproduction and spread of pathogens
After the flood, the water quality will be greatly polluted. Because the flood will wash away a lot of rubbish, sewage and waste, which will be taken to other places and lead to water pollution. At the same time, the flood will also destroy the garbage treatment facilities and sewage treatment facilities, so that garbage and sewage can not be properly treated. All these will lead to the breeding and spread of pathogens.
The occurrence of plague
After the flood, pathogens will multiply in the polluted water. These pathogens will spread to human body through water and air, which will lead to the occurrence of plague. Plague is an infectious disease, which can cause fever, cough, dyspnea and other symptoms. If not treated in time, plague may lead to death.
Methods of preventing and controlling plague
To prevent and control the plague, we need to take some effective measures. First of all, we need to strengthen environmental sanitation management to ensure that garbage and sewage are properly treated. Secondly, it is necessary to strengthen pathogen monitoring and prevention and control, and find and deal with pathogens in time. Finally, we need to strengthen public health education and improve people's health awareness and self-protection ability.
