Health officials in the United Kingdom are raising alarms about the spread of norovirus, commonly known as the winter vomiting bug. The UK Health Security Agency (UKHSA) has issued a warning as the illness is expected to proliferate during this season, which typically sees an uptick in viral infections. The agency advises the public to take precautions to avoid contracting the virus, which can cause sudden and severe symptoms.
Norovirus is notorious for striking unexpectedly and usually lasts for about 48 hours. Symptoms include vomiting, diarrhoea, and nausea, which can be distressing for those affected. The National Health Service (NHS) highlights that in addition to gastrointestinal symptoms, individuals may also experience a high temperature, headaches, stomach cramps, and general body aches.
Prevention and Symptoms
The UKHSA emphasizes the importance of self-isolation to prevent the virus from spreading. Individuals experiencing symptoms should avoid schools, workplaces, hospitals, and care homes until at least 48 hours after their symptoms have subsided. Staying hydrated throughout the illness is crucial, as dehydration can occur rapidly due to vomiting and diarrhoea. The NHS advises, “The most important thing is to have lots of fluids to avoid dehydration.”
Norovirus can be transmitted through various means, including inadequate hand hygiene after using the toilet, close contact with an infected person, touching contaminated surfaces, or consuming contaminated food and water. To mitigate the risk of infection, the NHS recommends several preventive measures:
– Wash hands thoroughly with soap and water after using the toilet or changing nappies, as alcohol-based hand gels are ineffective against norovirus.
– Wash hands with soap and water before preparing, serving, or eating food.
– Launder any clothes or bedding that have come into contact with vomit or faeces at a temperature of 60 degrees Celsius, and wash them separately from other laundry.
– Clean surfaces such as toilet seats, flush handles, taps, and bathroom door handles regularly.
– Minimize contact with others while symptomatic.
What to Do If Infected
If you exhibit symptoms of norovirus, the NHS provides specific guidance on managing your health and preventing further transmission. You should:
– Remain at home and rest, avoiding work or sending children to school until 48 hours after symptoms have ceased.
– Refrain from visiting a GP or hospital while symptomatic. Instead, consult your GP by phone or contact NHS 111 for advice.
– Drink plenty of fluids to combat dehydration resulting from vomiting and diarrhoea.
– Avoid cooking or preparing meals for others until 48 hours after symptoms have ended.
– Maintain rigorous hand hygiene and disinfect any contaminated items or surfaces.
If symptoms persist, such as diarrhoea lasting more than seven days or vomiting for over two days, it is advisable to contact NHS 111 for further assistance.
With winter approaching, the UKHSA’s warning underscores the need for public awareness and proactive measures to curb the spread of norovirus. By following these guidelines, individuals can help protect themselves and those around them from this highly contagious virus.
