summary

I believe that when you hear about cholera, you will feel that it is highly infectious. You will often hear it in ancient costume plays to explain the knowledge about cholera to you.

What is cholera

First of all, cholera is an acute diarrhea infectious disease caused by Vibrio cholerae contamination of food or water. Every year, it is estimated that there are 3-5 million cholera cases and another 100000-120000 deaths. This disease often occurs in summer, and the onset time is uncertain. It can cause diarrhea, dehydration and even death in a few hours.

Then cholera is caused by Vibrio cholerae. O1 and O139 serotypes can cause disease outbreaks. Most outbreaks are caused by Vibrio cholerae O1, while O139, first identified in Bangladesh in 1992, is limited to Southeast Asia. Non-O1 and non-O139 Vibrio cholerae can cause mild diarrhea, but will not cause epidemic. Recently, new mutants have been found in some areas of Asia and Africa. It is observed that these strains can cause more serious cholera disease, and the number of deaths is rising.

Finally, Vibrio cholerae is present in water, and the most common cause of infection is eating water contaminated by patients' feces. Vibrio cholerae can produce cholera toxin, causing secretory diarrhea, even if no longer eating will continue diarrhea, washing rice water like feces is the characteristic of cholera.
