Diarrhea occurs when you have looser or more frequent bowel movements than usual. This is one of the main symptoms of gastroenteritis, the other being vomiting. Gastroenteritis is an inflammation of the stomach or intestines that results from a bacterial or viral infection. Diarrhea usually lasts 2-4 days without the need for treatment, however severe diarrhea can be life-threatening. This watery diarrhea is caused by fluid loss, especially in infants and young children, the malnourished and those with weakened immune systems. Sadly, diarrheal disease is the second leading cause of death globally among children under the age of 5, accounting for approximately 760,000 child deaths each year.

The good news is that diarrhea is preventable. Through drinking safe water, improved hygiene (including the provision of proper facilities for the safe disposal of human waste) and practicing hand-washing hygiene with soap and water, the risk of diarrheal disease can be significantly reduced.
