Norovirus Warning: Stay at Home Message for 48 Hours Issued by UK Health Security Agency

The UK Health Security Agency (UKHSA) has advised the public to stay at home for 48 hours if they contract the highly contagious G11.17 strain of norovirus. The agency’s latest weekly update has shown that this variant is responsible for the majority of cases in the current winter season. Norovirus activity is on the rise across all age groups, with a significant increase in cases among adults, especially those aged 65 and over.

Between November 4 and 17, 2024, there was a 31.6% increase in norovirus cases compared to the previous two weeks. The number of reported outbreaks has nearly doubled the five-season average for the same period. The UKHSA has noted that the emergence of the uncommon norovirus genotype, GII.17, along with changes in epidemiology post-COVID-19, are contributing to the uptick in cases.

The most common strain circulating is norovirus genogroup 2 (GII), with GII.17 being the predominant subtype, accounting for 66.3% of cases. While there is a rise in cases, officials have not observed more severe symptoms associated with this strain. Symptoms of norovirus include vomiting, diarrhoea, high temperature, abdominal pain, and muscle aches. It is important to stay hydrated, especially for vulnerable groups like young children, the elderly, and individuals with weakened immune systems.

Amy Douglas, an epidemiologist at the UKHSA, emphasised the need to take precautions to prevent the spread of norovirus. It is crucial to refrain from returning to work, school, or preparing food for others until 48 hours after symptoms subside. Avoiding visits to hospitals and care homes while unwell is also advised. Regular handwashing with soap and warm water, along with using bleach-based products for cleaning, can help prevent the spread of infection.

In addition to the norovirus warning, the agency’s update included information on COVID-19, flu, and Respiratory Syncytial Virus (RSV). While COVID-19 levels remain stable, cases of flu and RSV have increased. The UKHSA urged individuals to be vigilant for symptoms of serious RSV infections, such as worsening cough, shortness of breath, and feeding difficulties, especially in children.

Dr. Alexander Allen, a consultant epidemiologist at UKHSA, highlighted the importance of vaccination against flu, COVID-19, and RSV to protect against winter illnesses. He encouraged those eligible for vaccination to get immunised before the onset of the busy winter season when respiratory viruses are more likely to spread.

As the UK prepares for the winter period, health authorities are urging the public to take proactive measures to safeguard their health and prevent the spread of infectious diseases.

Insights and Summary:
The UK Health Security Agency’s warning about the highly contagious G11.17 strain of norovirus underscores the importance of taking preventive measures during the winter season. With cases on the rise, it is crucial for individuals to stay informed about symptoms, practice good hygiene, and consider vaccination to protect themselves and others. The update serves as a reminder of the ongoing challenges posed by infectious diseases and the significance of public health interventions in mitigating their impact.
