What are the channels of transmission? >
As we all know, after the earthquake or tsunami disaster, the first outbreak of cholera in the hardest hit areas was cholera. In November 2017, Lusaka, the capital of Zambia, was enveloped by 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 were infected, 5 of whom died. As of March 2022, a total of more than 1,700 people were infected, and the number of deaths increased to 44.
It is known that 5 million people in Ethiopia are at risk of contracting cholera due to long-term drought and inadequate sanitation conditions. It can be seen that the impact of cholera on people is far more serious than we imagined. Recently, a case of cholera was exposed in Wuhan University, which has aroused widespread concern from all walks of life. Fortunately, it was discovered in time and the disease has been effectively controlled. So what is cholera that makes people frightened? And how is it spread? Let's look down.
Do you know what cholera is? Why is it listed as a Class A infectious disease? In what ways will it spread? Cholera is an acute diarrhea infectious disease caused by ingested food or water contaminated by Vibrio cholerae. Its main symptoms are diarrhea, vomiting and fever. In severe cases, acute renal failure may also occur. The acute illness is severe, the infection is fast and the spread is widespread, and it is listed 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 period of positive stool, so no matter what Whether it is a light or heavy carrier, isolation treatment should be taken.
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. When it comes to this, everyone must be a little panicked, especially the students of Wuhan University, and the students in the school. People who shop at 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. The most important thing is to "take a good mouth". Cholera is actually very difficult to find.
Five of them include: washing hands before meals and after going to the toilet, cooking the seafood you buy home, reheating food every other meal or overnight, separating raw and cooked food, and seeing a doctor in time when symptoms occur. Do not include: do not drink uncooked raw water, do not patronize unlicensed restaurants, do not eat rotten food, overeating is not advisable, and do not touch unsterilized (cholera-contaminated) items. So the question is, how did cholera happen? Let's look down.
do you know? Cholera, which once ravaged the world, first broke out in India, and the main reason was related to the Ganges River in India. Everyone knows that the Ganges River is one of the birthplaces of Indian civilization and has the reputation of "holy river". Every year, 1-3 In January, at the confluence of the Ganges and the Yamuna, a bathing festival will be held. Hundreds of thousands of Indians will immerse themselves in the river to wash their bodies and souls. Not only that, but Indians will also scatter the ashes of the dead into the Ganges. Even in the Ganges, the corpses of the elderly often appear. Over time, the Ganges has become dirty and messy, becoming one of the dirtiest rivers in the world.
In 1816, a cholera epidemic broke out in the Ganges River Basin, and in the next four years, it spread throughout India. In 1820, China was in the late Qing Dynasty, and the public sanitation conditions were very backward, which also created a good environment 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 mess of the Ganges River in India. Many people say that the Indians opened The Pandora's box of cholera has since erupted 8 times around the world.
In the face of the raging and chaotic epidemic, human beings are also trying their best to think of countermeasures, but it is still a difficult problem to completely eliminate it. However, the level of medical care and sanitary conditions are constantly improving. Even if the cholera epidemic occurs, it will not be like before. So many casualties, let us hope that Wuhan can get rid of the clutches of cholera as soon as possible and restore the glory and tranquility of the past. What do you think of this?
