Diarrhoea is defined as the passage of loose, liquid or watery stools.
Stools are usually passed more than three times a day. WHO/UNICEF
define "acute diarrhoea as an attack of sudden onset, which
usually lasts 3 to 7 days, but may last up to 10-14 days. It is caused
by an infection of the bowel. The term "gastroenteritis" is
most frequently used to describe acute diarrhoea". In many cases
diarrhoea stools are watery but if blood is visible in stools, the
condition is called dysentery.
