diarrhoea – when stools (faeces) is less than firm. This can range from loose to being very watery. As a medical condition it is usually also associated with needing to go to the toilet more frequently.
For example, this is commonly defined as three or more liquid/watery faeces over 24 hour period.

Results are given as the number of copies of virus in a millilitre of blood (copies/mL).
