Question

how the molera be prevented

Answer 1

Drink only water that you have boiled or treated with chlorine or iodine. Other safe beverages include tea and coffee made with boiled water and carbonated, bottled beverages with no ice. Eat only foods that have been thoroughly cooked and are still hot, or fruit that you have peeled yourself.

Dude your spelling is wrong... It should be cholera not molera

Hope this will help you... ✌
