There are cholera cases in Wuhan University. When did cholera start?

Cholera has actually existed for a long time, but some people may not understand it. According to records, there have been seven cholera pandemics in the world, and the number of those small outbreaks is even more. At present, we don't know when the disease first appeared, because the previous records were not so detailed. The latest record of this disease should be in 1543. A Portuguese historian wrote a book called Legend of India. He described that 1543, a disease broke out in the Ganges Delta of South Asia in Bangladesh. At that time, the mortality rate was particularly high, and many people died within eight hours.

In the following centuries, the disease broke out in many countries, including Britain, France, Henan, Portugal and so on. The first chaotic parade in history was also caused by contaminated rice. 18 17 broke out in the Ganges delta. At that time, after the local outbreak, the disease instantly spread to many parts of India, including Myanmar and modern Sri Lanka. By 1820, it has spread to Indonesia, Thailand and the Philippines. Not only that, it also spread to China and Japan, including some countries outside Asia, such as Turkey and Syria.

This disease is currently classified as a Class A infectious disease. It can be seen from this aspect that it is highly contagious, so it is particularly serious. The third outbreak of the disease was terrible, which caused 23,000 people to rise in Britain alone, and it was a year. Although many places are under control now, the disease has not been cured or eradicated, so it will always appear suddenly somewhere in the world, but fortunately it has not caused a large-scale infection. So it's still terrible, so everyone must pay more attention.
