With norovirus cases on the rise in the UK, the UK Health Security Agency has confirmed that the number of cases is unusually high for this time of year. Norovirus is a highly contagious stomach bug that causes symptoms like vomiting, diarrhea, high temperature, headache, and muscle aches. It usually resolves within two days. The virus can spread through close contact, contaminated surfaces, and food prepared by infected individuals. Recent changes in testing and the cold weather in spring are believed to have contributed to the increase in cases.
Hand sanitizers do not effectively kill norovirus, unlike other viruses. Washing hands thoroughly with soap and water is the best way to prevent its spread. If infected with norovirus, individuals are advised to stay off work or school, avoid hospitals and care homes, get plenty of rest, and stay hydrated. Most people start to feel better within a few days. In April, the number of confirmed norovirus cases was 75% higher than the expected average for that time, prompting the UKHSA to investigate the reasons behind this uptick. Norovirus can lead to dehydration, especially in vulnerable groups, so staying hydrated is crucial.
People can contract norovirus through contact with infected individuals, contaminated surfaces, or consuming infected food. Oysters and raw shellfish are common sources of the virus as they are often eaten raw. The symptoms of norovirus include nausea, vomiting, diarrhea, fever, headache, and muscle aches. While alcohol hand gels are ineffective against norovirus, cleaning surfaces with bleach-based products and washing hands with soap and warm water can help prevent its spread. It is essential to stay away from public places and avoid preparing food for others if infected.
The UKHSA recommends that individuals who suspect they have norovirus should isolate themselves to avoid passing on the infection. Staying hydrated, getting plenty of rest, and refraining from preparing food or visiting hospitals and care homes can help contain the virus. Cases of norovirus have been on the rise, surpassing what would typically be expected for this time of year. The agency attributes this increase to a combination of factors, including changes in testing practices since the Covid-19 pandemic and the cold spring weather. Practicing good hygiene habits and following guidelines can help limit the transmission of norovirus.
With the severity of norovirus-related symptoms, individuals are advised to take precautions if they suspect they have been infected. Dehydration can be a significant concern, especially for vulnerable groups like children and older adults. The agency underscores the importance of hand hygiene, surface cleaning, and staying home if ill to prevent the spread of the virus in the community. Symptoms of norovirus can be debilitating but usually resolve within a few days with proper care. Awareness of preventive measures and early intervention can help mitigate the impact of norovirus outbreaks in the population.
