A Liverpool school is closing for two days after more than a quarter of its pupils fell ill with a sickness bug.
About 55 out of the 209 pupils at Banks Road Primary School in Garston are suffering from the virus, thought to be either norovirus, rotavirus or both.
A spokeswoman for the school said it was closing for "infection control".
A Liverpool council spokesman said more pupils were sent home throughout the day and the premises would be given a deep clean before re-opening on Monday.
Norovirus is highly infectious and one of the most common causes of gastroenteritis in the UK, particularly in winter.
It is known as the winter vomiting disease due to its seasonality and typical symptoms.
Rotavirus causes diarrhoea, vomiting, abdominal pain, fever and dehydration.
The Health Protection Agency said anyone infected with Norovirus will normally recover in anything from 12 to 60 hours without treatment.
