When you're on vacation it pays to be extra cautious about what you eat. Incompletely cooked and contaminated food, particularly raw milk, and salads and unboiled water, are infested with bacteria. Campylobacter, Gram-ve organism like E. Coli and Salmonellae and/ or E. Histolytica are the widest known causes of Traveller's Diarrhoea. It commonly affects the very young and the elderly.

Other causes of Diarrhoea ::
Viruses-Rotaviruses, adenoviruses, and enteroviruses. Parasitic infections, Excessive alcohol. Coarse or oily food. Drugs administered to reduce high blood pressure.

Most outbreaks are self-limiting and do not need specific treatment. A strict diet helps put the stomach back in order quickly. Avoid oily food. Drink plenty of fluids with salt; dehydration is the greatest danger diarrhoea patients face. In some case, antibiotics and anthielmenthics help. But check with your doctor first.
