UKHSA Warns Norovirus Infections Remain High, Issues 48-Hour Rule Alert
The UK Health Security Agency (UKHSA) has issued a stark reminder to the public regarding a persistent winter bug, emphasising that infections remain high despite a recent decline. Health experts are urging individuals to adhere to a critical 48-hour rule if they experience symptoms, to prevent further spread of the illness.
Norovirus Cases and Impact on Older Adults
Norovirus, commonly known as the winter vomiting bug, is an unpleasant illness characterised by symptoms such as vomiting and diarrhoea. According to the latest data from the UKHSA, cases from the period of February 16 to March 1 were 30.5 per cent higher than the five-season average. Notably, people over the age of 65 have been the worst affected by this outbreak, highlighting the vulnerability of older adults to such infections.
Amy Douglas, lead epidemiologist at UKHSA, stated: "Norovirus remains high but has started to decrease in recent weeks. Cases remain highest among people aged 65 years and over." She stressed the importance of vigilance, as overall cases have begun to decrease, but the risk of transmission persists.
Essential Hygiene and Prevention Measures
To combat the spread of norovirus, Ms Douglas outlined several key hygiene practices. She advised: "Wash your hands with soap and warm water and use bleach-based products to clean surfaces to help stop infections spreading. Alcohol gels do not kill norovirus so don’t rely on these alone." This guidance is crucial, as improper hygiene can exacerbate outbreaks.
The NHS supports this advice, recommending additional steps to prevent infection:
- Wash hands with soap and water after using the toilet or changing nappies.
- Wash hands before preparing, serving, or eating food.
- Wash contaminated clothes and bedding separately on a 60°C wash.
- Clean high-touch surfaces like toilet seats and door handles regularly.
- Avoid contact with others as much as possible when symptomatic.
48-Hour Rule and Symptom Management
Central to the UKHSA's alert is the 48-hour rule, which mandates that individuals with diarrhoea and vomiting should not return to work, school, or nursery until 48 hours after symptoms have ceased. Ms Douglas emphasised: "Don’t prepare food for others in that time either. If you are unwell, avoid visiting people in hospitals and care homes to prevent passing on the infection to those who are the most vulnerable."
Symptoms of norovirus can appear suddenly and typically include nausea, vomiting, diarrhoea, high temperature, headaches, stomach cramps, and body aches. The NHS advises seeking medical attention if diarrhoea lasts more than seven days or vomiting persists beyond two days by calling 111.
By following these guidelines, the public can help reduce the impact of norovirus and protect vulnerable populations during this ongoing health concern.
