Health officials have issued an urgent warning to parents across the UK as new data reveals a significant spike in norovirus cases, with young children being the most vulnerable group.
Children Under Five Most Affected
According to the latest figures from the UK Health Security Agency (UKHSA), infection rates are currently highest among children aged 0 to 4 years. The agency is urging parents to be vigilant and to keep their children away from school or nursery for at least 48 hours after their symptoms have completely subsided.
The virus, often called the winter vomiting bug, is highly contagious and spreads through close contact, contaminated surfaces, or infected food. It causes severe vomiting and diarrhoea, typically lasting around two days, though it can persist longer, especially in vulnerable individuals.
How to Stop the Spread
Amy Douglas, Lead Epidemiologist at the UKHSA, emphasised that while norovirus activity is at expected levels for this time of year, simple steps are crucial for containment. "Norovirus activity has remained within expected levels in recent weeks, but it’s important to remember the simple steps we can take to prevent the spread," she stated.
Douglas advised the public to practice thorough handwashing with soap and warm water, as alcohol-based gels are ineffective against the virus. Surfaces should be cleaned with bleach-based products. She also stressed that anyone who is unwell should avoid preparing food for others and visiting hospitals and care homes for 48 hours after symptoms end to protect vulnerable people.
Recognising Norovirus Symptoms
The primary symptoms of a norovirus infection include sudden-onset nausea, projectile vomiting, and watery diarrhoea. Sufferers may also experience a high temperature, abdominal cramps, and aching limbs.
Dehydration is a key concern, particularly for the very young and elderly. It is vital to drink plenty of fluids if you become ill. While most cases resolve within two days, medical advice should be sought via NHS 111 if a child stops feeding, or if vomiting continues for more than two days or diarrhoea for more than seven days.
