What does it mean that there will be a demon after the plague is over 3?
In the past, no matter where people were, they were constantly tortured, so there was a saying that "three times will inevitably lead to disaster." The word "three" here means a long duration, such as three years, and a lot of times, such as three consecutive times.
There have been many plagues in history, but few of them lasted more than three years. So many people predict that the COVID-19 epidemic will end within three years, but the COVID-19 epidemic is very different from the previous epidemic.
This proverb has no clear source, but it was handed down by the older generation. There is no scientific basis and no relevant proof.
Epidemics in history:
1, Black Death:
Refers to the plague, which is one of the deadliest plagues in human history, causing 75 million deaths worldwide. It is generally believed that it is caused by a bacterium called plague. Nature even claimed that the "Black Death" 700 years ago left a genetic imprint on the epidemic, which has affected human health so far.
2. Smallpox:
One of the oldest infectious diseases with the highest mortality rate is poxvirus, and there is no specific medicine for infected people. The patient will leave a pockmarked face after recovery, hence the name "smallpox", which is mainly characterized by severe viremia and high mortality after infection.
3.cholera:
An acute intestinal infectious disease, mainly diarrhea, caused by Vibrio cholerae. Vibrio cholerae can produce cholera toxin and cause secretory diarrhea. Even if it stops eating, it will continue to have diarrhea. At present, cholera virus still exists in many African countries and India with high temperature all the year round.
