The UK has been experiencing a rise in norovirus cases, including a significant increase in Wales. According to the latest figures from the Welsh Government, there has been a nearly 50% surge in confirmed cases of the virus. This spike in cases has been concerning, as norovirus, commonly known as the “winter vomiting bug,” spreads easily and can lead to sudden and unpleasant gastrointestinal symptoms. In England, the virus has also resulted in a record number of hospital admissions, with an average of 1,160 patients being hospitalized each day due to norovirus, marking a 22% increase from the previous week and more than double compared to the same period last year.
Experts caution that these reported figures may only represent a fraction of the actual number of norovirus cases, as many individuals may not seek medical attention for their symptoms, which typically last around two days. Despite the rising cases, there are several preventive measures that can be taken to reduce the risk of contracting the virus and prevent its spread to others. One of the key steps recommended is practising good hand hygiene by washing hands thoroughly with soap and water, particularly after using the toilet and before eating or handling food. It is important to note that hand sanitizers are not effective against norovirus.
In addition to hand hygiene, regularly disinfecting high-touch surfaces such as door handles, light switches, and kitchen counters with bleach-based disinfectants can help eliminate the virus. Properly handling food is also crucial in preventing norovirus transmission, including washing fruits and vegetables thoroughly and cooking seafood, especially shellfish, to safe temperatures. Individuals who are unwell with norovirus symptoms are advised to stay at home to prevent spreading the infection further and should refrain from returning to work, school, or public places until at least 48 hours after their symptoms have ceased, as the virus can still be contagious even after symptoms improve.
In Wales, Wendi Shepherd, Deputy Director in Health Protection for Public Health Wales, emphasized the importance of keeping children out of school or nursery for 48 hours after their symptoms have resolved. She highlighted the significance of thorough handwashing with soap and warm water, as hand sanitizer is ineffective against norovirus. Additionally, individuals with norovirus symptoms should avoid sharing towels and refrain from preparing food for others until they have fully recovered. The main symptoms of norovirus include vomiting, diarrhoea, mild fever, headaches, stomach cramps, and muscle aches.
As cases of norovirus continue to rise in the UK, it is crucial for individuals to be vigilant in following preventive measures to protect themselves and others from infection. By practising good hand hygiene, disinfecting surfaces, handling food safely, and avoiding contact when ill, the spread of norovirus can be significantly reduced. Public health officials urge the public to stay informed about the virus and take necessary precautions to minimise the risk of contracting norovirus during this heightened period of transmission.
