Vomiting and diarrhoea are usually caused by irritation of the digestive system and can occur together or separately. Both can be caused by parasites, viruses or bacteria and it causes the body to lose essential salts and fluids risking dehydration.
If you are concerned about a casualty's condition, if they are a child or an older person or if the vomiting and diarrhoea persists, seek medical advice.
