Rotavirus
Rotavirus is the most common virus to cause gastroenteritis (a gut infection that results in diarrhoea, vomiting, fever and stomach cramps) in children in the UK. Most children have experienced this illness by the time they reach the age of five. Rotavirus often spreads in homes, nurseries and schools as it can live on hard surfaces such as door handles, toys or furniture for a long time.

About rotavirus
Rotavirus is a virus that is a common cause of diarrhoea in children. By the age of five, almost all children will have encountered it, usually during the first two years of life.
Rotavirus diarrhoea occurs in annual epidemics every spring. Although many children die throughout the world from rotavirus infections, children infected in the UK and other developed countries rarely become seriously ill.
Rotavirus symptoms
The most common symptoms of rotavirus are severe watery diarrhoea, vomiting, fever, and/or abdominal pain. These symptoms will usually start about two days after being exposed to rotavirus and last for three to eight days.
People can also experience loss of appetite and dehydration, which can be dangerous for infants and young children.
Possible complications
Every year in the UK, several thousand children are admitted to hospitals with dehydration caused by rotavirus diarrhoea.
Symptoms of dehydration include decreased urination, a dry mouth and throat, feeling dizzy, crying with few or no tears, unusual sleepiness, or fussiness.
Rotavirus can be fatal in rare cases; in the UK, around three or four children die every year from rotavirus infection.

Rotavirus statistics
Rotavirus is not a notifiable infectious disease, which means that cases don’t have to be reported. As a result, we don’t know the exact number of cases in the UK or worldwide over the past 12 months.
Research from 2018 found that, worldwide, rotavirus infection caused 128,500 deaths and 258,173,300 episodes of diarrhoea among children younger than five years in 2016 (more recent global figures aren’t currently available).
According to the Vaccine Knowledge Project, each year in the UK:
- 130,000 children are so unwell with rotavirus that they needed to see their GP
- Approximately 36,000 children with rotavirus are taken to A&E
- Around 12,700 of these are admitted to hospital, usually because of severe dehydration
- It is thought that three or four children die each year in the UK as a result of rotavirus infection, and some people have given higher estimates
- Death is typically due to severe dehydration caused by diarrhoea and vomiting
You can search the Office for National Statistics (ONS) website for the most recently published information about deaths where rotavirus was registered as an underlying cause.
