Causes Norovirus Cases to Double – Expert Warns of Key Symptoms and Prevention Tips
Norovirus cases have surged in the UK, with instances of the “winter vomiting bug” doubling compared to last year, according to The Mirror. Dr. John Burke, a seasoned GP with 25 years of experience and Chief Medical Officer at AXA Health, has highlighted the symptoms and prevention methods as a new strain, known as the “Kawasaki bug,” spreads rapidly. Originally discovered in Japan in 2014, this strain now accounts for 70% of current norovirus cases across the UK.
Dr. Burke explained the severity of the virus, stating, “Norovirus is an extremely contagious virus that spreads through contact and can cause sickness and diarrhoea for those infected.” He noted that cases rise sharply during autumn and winter due to closer indoor interactions, amplifying the risk of transmission.
To help those experiencing symptoms, Dr. Burke recommends managing the illness at home, as it generally resolves within a few days. Simple treatments, such as over-the-counter medications, can ease symptoms, while bland foods like toast and crackers are best when struggling with nausea. “Try to keep your meals bland while you’re unwell with norovirus to avoid further upsetting your stomach,” he advised.
Staying hydrated is also essential, especially given the dehydration risk associated with vomiting and diarrhoea. “Our bodies lose a lot of fluids through vomiting and diarrhoea,” Dr. Burke said, urging people to consume clear fluids and electrolytes consistently. Additionally, he emphasized the importance of rest, advising that anyone with norovirus allow at least 48 hours for recovery before returning to work or school.
Preventing the spread of norovirus is a primary concern, and Dr. Burke urged strict hygiene measures. “If you become infected with norovirus, it’s essential to practise proper hygiene and cleanliness,” he noted, recommending thorough disinfection of surfaces and personal items. Dr. Burke also warned against preparing food for others while symptomatic to avoid contamination, as norovirus is highly contagious.
He advised those infected to avoid public contact for at least 48 hours after symptoms have cleared to reduce the spread.
The virus’s contagious nature has prompted trials for the first vaccine against norovirus in the UK, offering potential hope for future prevention of this seasonal illness.
