What are the differences between dysentery and diarrhoea?

Show Hint

The presence of blood or mucus in stool distinguishes dysentery from simple diarrhoea. If you notice blood in your stool along with severe abdominal pain and fever, seek medical help immediately rather than self-medicating with over-the-counter anti-diarrhoeal drugs.
