This weekly bulletin brings together the latest surveillance data, along with the latest public health advice for flu, COVID-19, respiratory syncytial virus (RSV) and other viruses.
According to the latest surveillance data from the UK Health Security Agency (UKHSA), Norovirus cases have increased by 47% in the first 2 weeks of 2026, compared to the previous 2-week period ending 28 December, prompting a reminder about good hygiene measures to halt the spread of the virus, News Cover reports, citing UK government.
Reports remain highest among those aged 65 years and over and although activity remains within expected levels, outbreaks in hospital settings are also rising.
UKHSA’s latest surveillance data also shows that flu, COVID-19 and RSV levels continued to decline in the first week of the year. While cases for all winter viruses remain within expected levels for this time of year, people are urged to continue taking simple steps to ensure this trend continues. Viruses like flu and norovirus can be unpredictable and trends can change throughout the season which is why it’s important that people take simple steps to reduce the spread.
For both respiratory and gastrointestinal viruses like norovirus, this includes washing hands regularly. Remember that alcohol gels do not kill norovirus, so regularly washing hands with soap and warm-water and using bleach-based products to clean surfaces will also help stop infections from spreading.
Making sure indoor spaces are well-ventilated can reduce the spread of respiratory infections like flu, and if you have symptoms, stay home where possible. If you need to go out, consider wearing a face covering particularly if visiting vulnerable people.
