Winter bug cases surge, hitting elderly hard

Norovirus infections are currently at elevated levels, with cases reported as 50% higher than the five-season average. Older adults, particularly those aged 65 and over, are most affected, and hospital outbreaks have seen an increase. Health experts emphasize basic hygiene practices such as thorough handwashing with soap and warm water and cleaning surfaces with bleach-based products, noting that alcohol-based hand sanitizers are not effective against norovirus.

Individuals experiencing vomiting or diarrhea are advised to stay home for at least 48 hours after symptoms cease and to avoid preparing food for others during this period. Visiting hospitals and care homes while unwell should also be avoided to protect vulnerable populations. People with asthma are particularly at risk, as any acute illness can exacerbate respiratory symptoms.

Despite the ongoing high numbers, recent data suggests that norovirus may have peaked, with a recent week-on-week fall in hospital admissions for related symptoms. Similarly, cases of flu and RSV have been declining since the start of 2026. However, health authorities stress the importance of continued caution as the flu season is not yet over, and respiratory viruses can be unpredictable.
