Cholera

Cholera is an acute, diarrhoea illness caused by infection of the intestine with the bacterium Vibrio cholerae. The infection is often mild or without symptoms, but sometimes it can be severe.

Occurrence: Cholera occurs primary along the Ganges river and in Bangladesh. Epidemics can spread in other countries.

The transmission is through contaminated water and food.

Manifestations:

The disease is characterised by:

• Profuse watery diarrhoea
• Vomiting
• Leg cramps.
• Rapid loss of body fluids
• Dehydration
• Shock.
• Without treatment, death can occur within hours.

Diagnose and treatment: The bacteria can be demonstrated in stools. Cholera can be simply and successfully treated by immediate replacement of the fluid and salts lost through diarrhoea. Patients can be treated with oral rehydration solution, a pre-packaged mixture of sugar and salts to be mixed with water and drunk in large amounts. This solution is used throughout the world to treat diarrhoea. Severe cases also require intravenous fluid replacement. With prompt rehydration, less than 1% of cholera patients die.

Antibiotics shorten the course and diminish the severity of the illness, but they are not as important as rehydration.

Vaccine against cholera is available.
