Cholera disease and symptoms
Cholera is a severe, highly contagious diarrhoeal disease, caused by vibrio Cholerae, from the gram negative bacillus.
The disease results in a profuse diarrhoea, sometimes with the occurrence of vomiting a few hours after the ingestion of contaminated (by V. cholerae bacillus) food or water. For most of the victims, the symptoms subside after a few days, but sometimes the diarrhoea and the vomiting are so intense that dehydration leads to death, if no rehydration measure is provided to the patient.
Symptoms of cholera infection may include:
- Diarrhea. Cholera-related diarrhea comes on suddenly and may quickly cause dangerous fluid loss — as much as a quart (about 1 liter) an hour. Diarrhea due to cholera often has a pale, milky appearance that resembles water in which rice has been rinsed (rice-water stool).
- Nausea and vomiting. Occurring especially in the early stages of cholera, vomiting may persist for hours at a time.
- Dehydration. Dehydration can develop within hours after the onset of cholera symptoms. Depending on how many body fluids have been lost, dehydration can range from mild to severe. A loss of 10 percent or more of total body weight indicates severe dehydration.
Dehydration may lead to a rapid loss of minerals in your blood (electrolytes) that maintain the balance of fluids in your body. This is called an electrolyte imbalance.
