This acute, diarrhoeal illness is caused by bacterial infection. 90% of the cases are mild, only about 10% of the infected are severely sick.
Cases occur in all countries of Southern Africa, but following basic food safety recommendations, risk of infection is very low.
Cook it, peel it or leave it! Avoid contact with contaminated water in rivers, dams and lakes. In KwaZulu Natal do not swim in any water other than chlorinated swimming pools or clear seawater. Oysters and shellfish harvested along the KwaZulu Natal Coasts should not be consumed uncooked.
Mild to severe diarrhoea, hard to distinguish from travellers’ diarrhoea. Severe cases lead to dehydration rapidly.
Re-hydration solution: 1 litre of freshly boiled water. Add ½ a level teaspoon of salt and 8 level teaspoons of sugar. Add little fruit juice or some mashed banana.
