As we all know, after the earthquake or tsunami, the first epidemic in the hardest-hit areas was cholera. In November 2017, Lusaka, the capital of Zambia, was shrouded in the cholera epidemic. Due to the lack of effective control, the number of confirmed infections was nearly 300. For example, the death toll was 4. In June 2019, a large-scale cholera epidemic occurred in Ethiopia, causing more than 500 people to be infected and 16 people to die. More than 160 people have been infected, 5 of them have died, and as of March 2022, a total of more than 1,700 people have been infected, and the number of deaths has increased to 44.

It can be seen that the impact of cholera on people is far more serious than we thought. Recently, a case of cholera was exposed in Wuhan University, which has aroused widespread concern from all walks of life.

Do you know what cholera is? Why is it classified as a Class A infectious disease? In what ways will it be spread? Cholera is an acute diarrheal infectious disease caused by Vibrio cholerae contamination of ingested food or water. Its main symptoms are diarrhea, vomiting and fever. In severe patients, acute renal failure may be complicated. It is classified as a Class A infectious disease in China. The incubation period of cholera is generally several hours to 5 days, of which 2-3 days are the most common, and the infected person is contagious during the positive stool period. Both light and heavy carriers should be treated in isolation.
Generally speaking, most of the transmission routes of cholera can be avoided. For example, water sources and seafood contaminated by Vibrio cholerae can be used as transmission routes. Everyone must be a little panicked here, especially the students of Wuhan University, as well as the students at school. Citizens who consume in nearby snack bars are worried that they will be infected. In fact, the method of preventing cholera is relatively simple. As the saying goes, the disease enters from the mouth. Cholera is actually hard to come by.

So the question is, how did cholera happen? Let's look down.
do you know? The cholera that once plagued the world first broke out in India, and the main reason is related to the Ganges River in India. As we all know, the Ganges River is one of the birthplaces of Indian civilization and has the reputation of "Holy River". Every year 1-3 Every month, at the confluence of the Ganges and Yamuna, there will be a bathing festival. Hundreds of thousands of Indians are immersed in the river to wash the filth of their bodies and minds. Not only that, but the Indians will also scatter the ashes of the dead in the Ganges. Even the corpses of old people often appear in the Ganges. Over time, the Ganges becomes dirty and becomes one of the dirtiest rivers in the world.
In 1816, a cholera epidemic broke out in the Ganges River Basin, and in the following four years, it spread throughout India. In 1820, China was in the late Qing Dynasty, and public expectations were that the sanitary conditions were very backward, which also created good conditions for the epidemic of cholera. Conditions, Shandong, Jiangsu, Henan and other places are the hardest hit areas. Thousands of people lost their lives due to the cholera epidemic. They also paid a heavy price for the filth of the Ganges River in India. Many people say that the Indians have opened Cholera's Pandora's Box has erupted 8 times around the world since then.
In the face of the raging epidemic, human beings are doing their best to think of countermeasures, but it is still a difficult problem to completely eliminate it. However, nowadays medical standards and hygiene conditions are constantly improving, even if the cholera epidemic occurs, it will not be the same as before. With so many casualties, let us hope together that Wuhan can break away from the claws of cholera as soon as possible and restore its former glory and tranquility. What do you think of this?
