"cholera"的定义和意义

What is "cholera"?

Cholera is a bacterial infection that causes severe diarrhea and dehydration. It spreads through contaminated water or food, especially in places with poor hygiene. Cholera bacteria release a toxin that makes the intestines release lots of water, leading to watery diarrhea, vomiting, and fast loss of fluids and important minerals. Without quick treatment, severe dehydration can happen, which can be life-threatening. Treatment usually involves drinking special drinks with salt and sugar, called oral rehydration solution (ORS), or, in serious cases, getting fluids directly into a vein. Antibiotics may also be used to shorten the duration of symptoms and reduce the spread of the disease. Prevention of cholera involves improving hygiene, ensuring access to clean water, and vaccination in high-risk areas.
