Health bosses have issued a warning after a seasonal spike in norovirus cases.
Scientists say the number of cases reported in labs were up by more than 60% this winter, compared with the average over the past five seasons.
The majority of outbreaks in recent weeks were reported in care homes, with cases in over 65s at the highest level in over a decade.
The infection is the most common cause of vomiting and diarrhoea.
National surveillance data shows laboratory reports of the virus are 66% higher than the average at this time of year.

While high numbers of cases in this age group is expected at this time of year, these levels haven’t been seen in over a decade.
NHS Medical Director Stephen Powis has urged people to be vigilant after a spike in norovirus cases (PA)In response to the increase in cases, UKHSA is reminding the public of the actions that they can take to reduce the spread of norovirus.
Norovirus is highly infectious and is easily spread through contact with someone with the infection or with contaminated surfaces.
One of the best ways to prevent the spread of norovirus is by practicing good hand hygiene.
Most people will make a full recovery within two-three days but it is important to drink plenty of fluids to prevent dehydration, especially for the very young, elderly or those with weakened immune systems who are more at risk.
The number of outbreaks caused by norovirus have increased in hospitals, schools and care homes, with the majority of outbreaks reported in care home settings.
Dr Lesley Larkin, Surveillance Lead, Gastrointestinal Infections and Food Safety (One Health) Division at the UK Health Security Agency, said: “Norovirus levels are currently the highest we have seen at this time of year in over a decade. Most reported cases are in the over 65s and we’re also seeing a rise in reported outbreaks, particularly in care home settings.
"Please stay at home if you are experiencing norovirus symptoms and do not return to work (particularly if you work with vulnerable people or food) or send sick children to school or nursery until 48 hours after symptoms have cleared.
"If you have a loved one in a care home or hospital, please avoid visiting until 48 hours after symptoms have cleared.
“Regular hand washing is really important to help stop the spread of this bug, but remember, alcohol gels do not kill off norovirus so soap and warm water is best.”

NHS Medical Director Professor Sir Stephen Powis said: “The number of people in hospitals with norovirus has risen significantly in line with what we are seeing in the community and in care homes – it is a really unpleasant illness to catch, but for the vast majority of people it will usually pass in a couple of days, and self-treating at home is the best way to help yourself and avoid putting others at risk.”
