What is the cause of cholera? How can we effectively prevent cholera?

What is the cause of cholera? How can we effectively prevent cholera? The answer to this question is probably:

1, cholera is a kind of bacteria, which is really terrible.

According to scientific explanation, cholera is an acute diarrheal infectious disease caused by Vibrio cholerae polluting food or water. Once this bacterium enters the human body, it can cause diarrhea, dehydration and even death within a few hours, which is a national legal infectious disease. Its fatality rate can even be as high as 30%. Every year, it is estimated that there are 3 million to 5 million cholera cases and 654.38 million to 654.38 million deaths worldwide!

Usually, people will have symptoms of vomiting and diarrhea after being infected with cholera. After repeated for several hours, severe dehydration will occur, and then the eye socket will be deep, the lips will be chapped, and the skin will be extremely thirsty. Therefore, in the face of cholera, human beings have really suffered for a long time, and it is no exaggeration to say that once cholera is rampant, human beings may really face extinction.

2, drink more boiled water, wide street experiment,

Cholera germs are mainly transmitted by water and flies, as long as you drink plenty of boiled water at ordinary times? Pay attention to personal hygiene, wash your hands before drinking, before eating and after defecation, do not eat food that flies and insects have come into contact with, and do not eat peeled fruits and vegetables. Generally speaking, you won't get cholera.

Behind these conclusions, the expression of a few words is the victory of people's wisdom and rationality, because John? Si Nuo's wide street experiment in 1845 directly discovered the fundamental way of cholera endangering human beings and the method of preventing cholera. At the corner of Broad Street in Cambridge, public wells polluted by sewers have become the key for human beings to defeat cholera rationally. Although John? Si Nuo proved the relationship between cholera and water sources and sewers, and put forward a complete theory of cholera transmission. Limited by history.

But this theory really saved people, and then William? Farr's theory of cholera transmission is supported by scientific attitude, while Robert? Koch's discovery of Vibrio cholerae finally made people realize that cholera is not terrible, and we have an idea!
