UK households urged to follow ‘food rule’ amid warning of second virus wave | UK | News
British households are urged to follow a ‘food rule’ in the kitchen, as health chiefs warn of a potential second norovirus wave in the UK. The UK Health Security Agency (UKHSA) has warned that laboratory reports of the virus – which is also known as the winter vomiting bug – are at their highest ever levels.
Data shows that confirmed cases in the two weeks from February 3 to 16 are more than double the five-season average (168%) for this time of the year, with the increase in cases being linked to a recently detected strain. Experts warn that cases of the new strain have been sharply increasing, which means that people who have already had norovirus this season are at risk of catching it again, as having had one strain doesn’t fully protect against the other.
The virus causes gastroenteritis, which results in sudden nausea, projectile vomiting and diarrhoea. It can also cause a high temperature, headaches, aching limbs and abdominal pain.
Young children, older adults and those with weakened immune systems are more likely to develop more severe symptoms, which can result in dehydration.
Norovirus is highly contagious and is easily transmitted through contact with infected people or contaminated surfaces or objects, including food.
To help minimise the spread of the virus, people who experience norovirus symptoms are urged to stay at home for 48 hours until symptoms have stopped, and to follow a strict food preparation rule during this time.
Experts warn people not to cook or prepare food for others during this 48 hour period, as the virus can be spread by touching contaminated items and then touching your mouth. Households should also avoid eating any food that has been prepared or handled by someone with norovirus.
Amy Douglas, Lead Epidemiologist at UKHSA, said: “Norovirus levels are still exceptionally high and now with multiple genotypes spreading at the same time, people could end up getting infected more than once this season.
“We are seeing the biggest impacts in health and social care settings, such as hospitals and care homes. Symptoms of norovirus can be more severe in older adults, young children and those who are immunocompromised.
“If you have diarrhoea and vomiting, please do not visit hospitals and care homes or return to work, school or nursery until 48 hours after your symptoms have stopped. And don’t prepare food for others, as you can still pass on the virus during this time.
“Alcohol gels do not kill norovirus. Wash your hands with soapy warm water and clean surfaces with bleach-based products where possible to help stop infections from spreading.”
