A notoriously disabling condition with a number of names depending on the geographical location at which it strikes (e.g. Delhi belly and Montezuma's revenge). It often afflicts tourists in locations where food hygiene is poor. Traveller's diarrhoea is usually caused by certain types of the bacterium Escherichia coli. This microbe is a common inhabitant of the gut and is usually harmless. However, in a new locality, the gut may become infected with an unaccustomed strain which upsets the intestinal lining, preventing normal reabsorption of water. Treatment includes drinking plenty of fluids to regain water lost, and sometimes, antibiotics. The condition should be treated more seriously if diarrhoea is accompanied by blood in the stool, or fever. This may indicate a more serious condition, such as dysentery, that requires immediate medical attention.
