Norovirus warning issued as case levels remain ‘very high’

Norovirus, computer illustration. Norovirus is a genus of RNA (ribonucleic acid) viruses (of the family Caliciviridae), which cause about half of all gastroenteritis cases around the world. The disease is characterised by nausea, vomiting, diarrhoea and abdominal pain. The diarrhoea results in fluid loss and dehydration, which may become life-threatening in the young, the elderly, and the immunocompromised if not treated promptly.

England is seeing a ‘very high’ spike in norovirus cases, forcing health chiefs to issue a warning.

Cases of the highly infectious vomiting bug have been surging, mostly affecting people aged 65 and over.

NHS figures show an average of 551 adult hospital beds were occupied last week by patients with diarrhoea and vomiting or norovirus-like symptoms.

This is just over the 547 in the previous week, but it is more than double the 264 at this stage in 2022.

Outbreaks in schools are also running above the five-year average, affecting very young children.

Health experts fear this could put greater pressure on already struggling hospitals, with Covid admissions adding to demand for beds.

Dr Lesley Larkin, surveillance lead for gastrointestinal infections and food safety at the UK Health Security Agency (UKHSA), said outbreaks at schools have returned to pre-pandemic levels.

Parents have also been warned to be on the lookout as children in early years are ‘particularly affected’ by the illness.

But the highest rates are being seen in patients over the age of 65 and the under fives.

Dr Larkin said: ‘Norovirus levels continue to be very high and most reported cases are in the over-65s.

‘Young children and older adults are at greater risk of developing dehydration while unwell with norovirus.

‘Dehydration can result in hospitalisation, so it’s important to drink plenty of fluids when unwell and contact NHS 111 or your GP surgery if you need advice.

‘Norovirus is very infectious but there are things we can do to stop the spread.

‘Hand gels do not kill norovirus so handwashing with soap and warm water is best.

‘If you or your child get the virus you should not return to work – particularly if you work with vulnerable people or food – or send your children back to school until 48 hours after symptoms stop.’
