Cholera is an infection of the small intestine by some strains of the bacterium Vibrio cholerae.[4][3] Symptoms may range from none, to mild, to severe.[3] The classic symptom is large amounts of watery diarrhea that lasts a few days.[2] Vomiting and muscle cramps may also occur.[3] Diarrhea can be so severe that it leads within hours to severe dehydration and electrolyte imbalance.[2] This may result in sunken eyes, cold skin, decreased skin elasticity, and wrinkling of the hands and feet.[5] Dehydration can cause the skin to turn bluish.[8] Symptoms start two hours to five days after exposure.[3]

Answer 2

Cholera :

This disease attacks the intestinal tract, and is caused by a special bacterium called vibrio. The patient suffers from vomiting and loose motions. There is very little or no urination because of the shortage of water in the body. Urea accumulates in the body, which is poisonous. The patient may die if not treated properly or promptly. The treatment includes saline water injection to supply water to the blood.

How it spreads :

The cholera germ is spread through food and water. The contamination results due to dust and by direct transport through flies. The flies sit on faeces of the patient and mechanically carry the germs which stick to their spiny legs and body, to the exposed food that is eaten up through the mouth.

How to prevent it :

Prevention method include good sanitation, killing flies, keeping the food and cut fruits properly covered to prevent the flies reaching them, boiling water for drinking, and eating well-cooked food. Immunization by taking anti-cholera injection is very useful.
