Norovirus cases have substantially increased in recent weeks, with a notable surge of 31% over a two-week period. This surge is attributed to the spread of a new variant named GII.17. According to figures published by the UK Health Security Agency (UKHSA), infections where 31.6% higher in the two weeks up to November 17 compared with the fortnight before. Cases are almost double the five-season average for the same period.
The NHS has warned that hospitals are “close to full” due to the surge in norovirus cases. amy Douglas, an epidemiologist at the UK Health Security Agency, stated that norovirus cases are “way above what we would usually see at this time of year and outbreaks in hospitals continue to rise.” Norovirus cases in England are currently more than double the expected number for this time of year.
To prevent the spread of the virus, Dr. Douglas has issued several warnings:
- Do not go to hospitals and care homes if you are sick: Norovirus spreads rapidly, especially among vulnerable individuals.It is crucial to stay away from hospitals and care homes if you are infected.
- Stay at home for at least 48 hours after the symptoms have passed: The virus can remain contagious even after symptoms disappear. Therefore, it is notable to stay at home for at least 48 hours after symptoms have subsided to prevent spreading the infection to others.
- Do not rely on alcohol-based hand disinfectants: Norovirus is resistant to alcohol gels. To effectively prevent the spread of the virus, wash your hands with soap and warm water, and disinfect surfaces with bleach-based cleaning products.

Norovirus cases have substantially increased in recent weeks, with a notable surge of 31% over a two-week period. This surge is attributed to teh spread of a new variant named GII.17. Data from the UK Health Security Agency (UKHSA) reveals that infections were 31.6% higher in the two weeks up to November 17 compared with the fortnight before.

Understanding the Norovirus Surge
World Today News recently caught up with Dr. Amy Douglas, an epidemiologist at the UK Health Security Agency. She provided insightful details on this recent outbreak.
Q: What triggered this surge in norovirus cases?
Dr. Amy Douglas: The recent surge in norovirus cases is largely attributed to the emergence of a new variant, GII.17. This variant appears to be more transmissible and has led to a significant increase in infections. The timing of the surge also correlates with the start of the winter season, when people tend to gather indoors more frequently, facilitating the spread of the virus.
Q: How does this variant compare to previous ones?
Dr. Amy Douglas: The GII.17 variant is notable for its increased transmissibility. Unlike previous strains, this one seems to be more resistant to conventional hand disinfectants, making it especially challenging to contain. Additionally, the symptoms it causes can be more severe, leading to higher rates of hospitalization.
Public Health Response and Prevention Tips
As the cases mount, health authorities are urging individuals to take preventive measures to curb the spread of the virus.
Q: What steps should individuals take to prevent the spread of norovirus?
Dr. Amy Douglas: First and foremost, individuals who experience symptoms should stay at home for at least 48 hours after the symptoms have passed. The virus remains contagious even after symptoms disappear, so this is crucial to prevent spreading the infection to others. Additionally, washing hands with soap and warm water, and disinfecting surfaces with bleach-based cleaning products, is more effective than relying on alcohol-based hand disinfectants.These measures can significantly reduce the risk of transmission.
Q: What advice would you give to healthcare facilities dealing with norovirus outbreaks?
dr. Amy Douglas: Hospitals and care homes should prioritize rigorous cleaning protocols,particularly in high-traffic areas. Ensuring that staff and visitors adhere to strict hand hygiene practices is essential. Additionally, screening for symptoms at the entrance and limiting visitor access can help contain the spread within these facilities. Advising staff and visitors to stay away if thay show symptoms is vital to preventing outbreaks within these sensitive environments.
Looking Ahead: Expectations for the Winter Season
The norovirus season typically peaks in the winter months, and with the current surge, the outlook for the coming weeks is concerning.
Q: What can we expect in the near future with regard to norovirus cases?
Dr. Amy douglas: Given the current trajectory, we can expect norovirus cases to remain high through the winter. The public should remain vigilant and follow preventive measures to protect themselves and others. Healthcare facilities must also be prepared for continued strain on their resources. As we learn more about the GII.17 variant, public health responses will be adapted to more effectively manage the outbreak.
Conclusion
The recent surge in norovirus cases, driven by the GII.17 variant, is a cause for concern. Through proactive preventive measures and rigorous public health interventions, we can mitigate the impact of this outbreak. Dr. amy Douglas’s insights highlight the importance of hand hygiene, surface disinfection, and vigilance in controlling the spread of the virus, particularly in high-risk settings like hospitals and care homes. As the winter season progresses, staying informed and taking the necesary precautions will be crucial for public health and safety.
