What is the principle of the saying a great plague will be followed by a great plague ?

The corpse is the ** of the epidemic? Many students take it for granted that corpses will definitely spread the epidemic. In fact, it is the survivors who are the ones who are at stake.

People who die in natural and man-made disasters often die from trauma. There is no necessary link between the corpses of traumatic deaths and the transmission of infectious diseases, and only in rare cases when a large number of people die from cholera or haemorrhagic fever and other virulent infectious diseases, these corpses cause infectious disease outbreaks. The vast majority of pathogens do not survive long on corpses, and the risk of large-scale transmission of infectious diseases from corpses to populations from natural disasters is minimal, but the staff who handle corpses may contract the disease due to frequent contact with corpses.

Infectious diseases in China are classified and managed according to the degree of harm, and they are divided into three categories: A, B and C, of which Category A is plague and cholera. The list is growing due to the emergence of emerging infectious diseases. Infectious diseases can be transmitted through different routes, such as influenza can be transmitted through the air, some infectious diseases such as dengue fever need to be transmitted through intermediate hosts, and sexually transmitted diseases are transmitted through bodily fluids.

Conditionally pathogenic bacteria are bacteria that do not cause disease in themselves, but cause infection when the person's immunity is weakened or the distribution of microorganisms in the body changes. For example, E. coli is found in the human gut and can synthesize many vitamins for us, and with the exception of a few pathogenic serotypes, most E. coli infections only occur when immunity is weakened or colonized outside the intestine. There are far more types of conditionally pathogenic bacteria than infectious disease pathogens.

In the event of a heavy rainstorm or flooding, the risk of contracting some contagious diseases increases.

For example, in 1998 there was a nationwide flood. In this flood, not only the safety of property was threatened. After the flood passed, the people of Hunan Province said that the gastrointestinal diseases and respiratory diseases of the early hunger in Hunan Province were more than three times that of ordinary times when there were no floods.

According to the research of the World Science Organization, in the Syrian region, many epidemic diseases brought about by the flood are not only contagious quickly, but also spread very widely, which can be said to be very terrible.

And many people may not have a home to go back to in the face of the catastrophic floods, so they will live in some relief shelters. People are more densely populated, and everyone can't eat or sleep well, so their immunity is relatively low.

At this time, there are many diseases that can invade the body, especially gastrointestinal diseases, so at this time, you must avoid drinking raw water, try to drink purified water, or boiled water, and avoid eating raw meat.

The words of the old man can only be used as a reference, and some have no scientific basis.

After the soldiers, there will be a great plague, and after the great plague, there will be a great famine. From the "Flower Boat" of the Xiling Maniac in the Ming Dynasty.

Meaning: After a great war and chaos in the world, there will be a great plague, and after the great plague, there will be a great famine.

From "The Flower Boat".

As the saying goes, it means that after a great war and chaos in the world, there will be a great plague, and after the great plague, there will be a great famine.

This is a phrase that has been handed down from ancient times and has no specific source.

An outbreak refers to a contagious disease in which residents within the area experience similar symptoms, such as fever, diarrhea, vomiting, etc. If you don't get timely treatment, it can lead to serious consequences such as death.

During the feudal period, the level of urbanization was very low, and the medical conditions were also very low, and whenever a serious natural disaster occurred, people could easily feel the epidemic and break out in a large area.
