Symptoms
Vibrio cholerae is the aetiological agent of cholera, an epidemic disease of significant public health importance owing to its rapid spread in areas with poor sanitation and hygiene, and its severe consequences when access to health care is limited.
Causes
V. cholerae pathogenicity genes code for proteins directly or indirectly involved in the virulence of the bacteria. To adapt the host intestinal environment and to avoid being attacked by bile acids and antimicrobial peptides, V. cholera uses its outer membrane vesicles (OMVs).
Prevention
- 1/2 a small spoonful of salt
- 6 level spoonfuls of sugar
- 1 liter of water
Complications
Rehydration therapy, the primary treatment for cholera patients, refers to the prompt restoration of lost fluids and salts. Antibiotic treatment reduces fluid requirements and duration of illness, and is indicated for severe cases of cholera. Zinc treatment has also been shown to help improve cholera symptoms in children.
