Current Trends in Respiratory Viruses
The latest surveillance data for the week of 12 to 18 October 2026 reveals that respiratory viruses are currently exhibiting stable patterns, with influenza activity remaining at baseline levels. The COVID-19 situation remains complex, showing mixed trends but still circulating at low levels. Respiratory Syncytial Virus (RSV) also presents with similar mixed trends, maintaining circulation at baseline levels.
Dr Jamie Lopez-Bernal, a Consultant Epidemiologist at the UK Health Security Agency, highlighted the importance of ongoing vigilance. “Our recent surveillance indicates that flu levels remain low, with a deceleration in the early rise observed in previous weeks. COVID-19 levels are similarly low. However, we will continue to monitor all significant respiratory viruses throughout the winter to identify trends promptly and keep the public well-informed,” he stated.
While current virus levels are manageable, predicting future trends remains challenging. Vaccination continues to be the most effective defence against these viruses. Those eligible are encouraged to schedule their free NHS vaccinations for flu, COVID-19, or RSV, and parents should ensure that their children receive the non-invasive nasal spray flu vaccine as soon as possible, ideally before the winter season prompts a rise in viral infections.
Influenza Surveillance Insights
During week 42 (12 to 18 October 2026), influenza activity has shown stability. Laboratory surveillance reflects a positivity rate of 6.3%, slightly up from 6.2% the previous week. Hospitalisation rates for flu have increased marginally to 1.94 per 100,000, compared to 1.81 per 100,000 in the prior week.
This consistent monitoring is crucial, as it allows health authorities to stay ahead of potential surges in influenza cases. Public health officials stress the importance of vaccination as a primary strategy to mitigate the spread of flu in the community.
COVID-19 Activity Overview
In terms of COVID-19, the latest data for the same week indicates that activity remains low, with a positivity rate of 8.9%, a slight increase from 8.8% in the previous week. Hospitalisations have risen to 2.64 per 100,000 from 2.48 per 100,000, while admissions to Intensive Care Units (ICUs) remain low at 0.05 per 100,000.
Despite these figures, the mixed trends in COVID-19 activity highlight the necessity for ongoing public health measures and vaccination efforts to prevent further transmission, particularly as the colder months approach.
RSV and Its Current Status
RSV activity has shown variable trends but remains at baseline levels. The positivity rate for RSV from laboratory tests has stabilised at 0.9%, a slight rise from 0.8% in the preceding week. The overall weekly hospital admission rate for RSV has increased to 0.33 per 100,000 from 0.23 per 100,000.
The surveillance data underscores the importance of continued awareness and preventative measures, especially for vulnerable populations who may be at higher risk of severe illness from RSV.
Norovirus and Rotavirus Updates
Analysis of norovirus activity between weeks 41 and 42 (5 to 18 October 2026) indicates a slight decrease, yet it remains within expected levels. Overall laboratory reports for norovirus during this period were 32.6% lower than the five-season average for the same timeframe.
In contrast, rotavirus activity has increased by 9.8% compared to the five-season average for the corresponding period. Thus far in the 2025/2026 season, a total of 42% fewer norovirus outbreaks have been reported compared to the five-season average, suggesting effective control measures are in place.
Symptoms of norovirus include nausea, vomiting, and diarrhoea, and can escalate to dehydration, particularly among vulnerable groups such as young children and the elderly. Therefore, it is crucial for individuals experiencing these symptoms to stay hydrated and seek medical attention if necessary.
Preventative Measures Against Norovirus
To combat the spread of norovirus, simple hygiene practices are vital. Regular handwashing with soap and warm water, along with the use of bleach-based cleaning products on surfaces, can significantly reduce infection transmission. Alcohol gels are ineffective against norovirus and should not be solely relied upon.
If experiencing diarrhoea and vomiting, individuals are advised to refrain from returning to work, school, or nursery until at least 48 hours after symptoms have ceased. It is also advisable to avoid food preparation for others during this time and to limit visits to hospitals and care homes to protect the most vulnerable individuals.
